The National Weather Service hasn't issued any expected precipitation totals for our area for the two upcoming storms. If they do, I'll post them.

The weather pattern is changing. We had a mostly cloudy night and morning, and rain is now in the forecast for Saturday, Sunday, and Monday. Today will be mostly cloudy with a high around 67°F. Tonight and Saturday morning will be mostly cloudy with a low around 42°F. Chance of rain (50%) begins Saturday, which will be mostly cloudy with a high around 62°F.

The winds will be with us through Sunday afternoon; expect sunny conditions Sunday and a high around 62°F. Looking ahead, the next chance of showers has been moved back to Thursday and Friday.

The wireless rain gauge appears to have accurately recorded yesterday's rain. I've had to move it to be within ten feet of the receiver. The location is not the best, so I will probably go back to a wired rain gauge that I can place across the backyard sometime soon. The rainfall total which was nearly 1/3 of an inch was much more than expected.

Partly cloudy today with showers possible later in the afternoon. The chance of rain is 60%, winds will be gusting to 25 mph, and the high temperature will be around 57°F.

TemeculaWeather.com was cited in a story in the Californian newspaper this morning about high winds and power outages in the Temecula area. The reporter seems to have used information directly from the web site. I was not contacted, I could have provided something more accurate than the hourly summary, which is currently a one hour sampling of winds and doesn't take gusts into account. For those that are interested, wind gusts Saturday morning reached a maximum of 35 miles per hour.

Nasty wind gusts and an unusually warm low temperature this morning are part of the latest Santa Ana wind condition currently affecting much of Southern California. These conditions, due to high pressure aloft, will erode starting today as a low pressure system begins to come in. The winds will begin diminishing this afternoon with a high of 82°F expected. Tonight will be mostly clear and won't repeat last night night's warmth; expect a low tomorrow morning of 44°F. Sunday will feature increasing clouds and a slight chance of rain (20%) in the late afternoon; expect a high of 69°F. Most of the rest of the upcoming week will have high temperature in the sixties with no rain the forecast.
It's not as cold as predicted this morning, so I doubt there will be any frost to worry about. The weather will be sunny and warmer today, with a high around 72°F. Tonight and Friday morning will be mostly clear with some gusty northeast winds possible. The low will be about 38°F. Friday will be sunny with gusty northeast winds possible and a high of 78°F. The chance of showers has been moved up to Sunday as a cold front will begin to move in then.
Possible patchy frost this morning, although I don't see any around my yard. It will be sunny today and warmer with a high around 69°F. Tonight and Thursday morning will be clear and chilly with patchy frost again possible and a low around 35°F. Thursday will be sunny and warmer still with a high of 78°F and wrong way winds possible. The warmer pattern is predicted to hold through the weekend before the next chance of showers on Monday.
Partly cloudy and clear today, with a small chance (20%) of a shower or two. Expect a high around 63°F. Tonight will be mostly clear and cold with patchy frost Wednesday morning and a low around 34°F. Wednesday will be mostly sunny and clear with a high of 74°F. The next slight chance of rain in the short term forecast is next Monday or Tuesday.

Mostly cloudy tonight as well with a 60% chance of showers. The low will be about 46°F. Tuesday will be partly cloudy and cool with showers possible and a high of 62°F as the storm leaves the area. The chance of measurable rain for Tuesday is 40%.
Increasing clouds this afternoon and a 30% chance of rain later with a high around 66°F. Rain will be likely by tonight (60% chance). Showers will continue through Monday morning, the low will be about 43°F. Monday will feature a 70% chance of showers and a high of 61°F. The heaviest showers are predicted for Monday afternoon. Winds will be gusting to 25 mph. The National Weather Service is predicting rain accumulations of 1/4 to 1/2 inch in coastal and valley areas from this storm.

Rain will be likely (60% chance) Sunday night, and is predicted to taper off to showers on Monday morning. The showers will continue Monday and are also possible Tuesday and Wednesday.
The clouds will be decreasing today from yesterday's storm. Temperatures were flat overnight due to the cloud cover, but expect some warming today up to 62°F. Tonight will be partly cloudy with a low of 41°F. Saturday expect partly cloudy conditions and a high around 63°F. Rain is predicted to return Sunday afternoon, with a 40% chance forecast.
It was a much warmer night and morning than expected or predicted, thanks the cloud cover, a welcome change from the past couple of nights and mornings.

Decreasing cloudiness on Friday with a 30% chance of showers in the morning and a high of 62°F. Looking ahead, there are stronger storms on track to hit the area, with the next one coming in on Monday.

9:45 amEQUIPMENT FAILURE The weather station appears to be partially inoperative. The failure seems to have occurred sometime after 7 am this morning. I'm going to have to back out several errant weather records, and travel from my office in San Diego back to Temecula to attempt to figure out if I can get things working again. In the meantime, ignore the low; it did not get any colder than 45°F this morning. My apologies, this is the first failure of this type in the three years I've been using this equipment. More on this when I've diagnosed what's going on ...

3:45 pm End to end connectivity fixed and things are operating normally again. An electrical short in the older rain gauge wreaked havoc this morning and it took a while to get everything sorted out. There was no permananent damage to the equipment and things are working with the wireless rain gauge again, which I've temporarily deployed very close the receiver to hopefully ensure that all the rain is measured. All of the errant data has been removed. A lot of today's rainfall was missed; I will correct that sometime tomorrow.

The cold, dry high pressure system will stay with us today. Frost conditions in some areas this morning will be followed by mostly sunny conditions, possible winds from the east, and a high around 67°F. Tonight and Thursday morning will feature increasing clouds and a low around 36°F. Frost is not currently called for in tomorrow's forecast. Thursday will be mostly cloudy with a high of 61°F and a chance of rain (50%) starting in the afternoon. The chance of showers Thursday night is 80%. The National Weather Service is predicting the upcoming storm will be weaker than the one we experienced last Saturday.
Mostly sunny and continued cool conditions today with a high of 63°F. There is a wind advisory issued for this morning; strong winds from the north east are possible, especially in canyons and passes. Tonight and Wednesday morning will be clear and gusty with a low of 35°F and frost in some wind-protected areas. Wednesday will be windy and sunny as well with a high of 67°F. The next chance of rain is Thursday afternoon, with the rain chance currently at 40%.

Some areas of the Temecula Valley may be experiencing frost conditions this morning. Yesterday I issued a first ever frost warning via email to subscribers to the email list. Just because a frost warning is issued doesn not mean it will happen; I try to err on the safe side. If you find this useful, consider subscribing the the list.

The new wireless rain gauge underreported actual rain totals for the recent storm. The actual total should have been between 0.59" and 1", according to other reports in the Temecula Valley. I'm temporarily going to switch back to the older rain gauge and will correct Saturday's reading to 0.59".

Rain is now out of the forecast until Thursday. Today will be partly cloudy with a high of 63°F. Partly cloudy tonight and Tuesday morning as well with a low of 38°F. Tuesday will be warmer and sunny with a high of 75°F.

I've added last year's high and low onto the site, and reorganized the high and low section.

Most of the storm passed through yesterday afternoon and early last night, leaving only 0.16" of rain. Already it is clearing and partly cloudy today, and that is expected through today, with a high around 63°F. Tonight will be mostly clear with areas of frost. Expect a low Monday morning around 34°F, the coldest of the season so far. Monday will feature increasing clouds and a high of 67°F. There is a slight chance (20%) of showers Monday night and Tuesday as a storm passes to the north. There will be another chance of rain Thursday according to the long term forecast.
Increasing clouds and wind today with a chance of rain in the afternoon and a high of about 64°F. The rain chance for this afternoon is 30%. Tonight will feature rain, heavy at times, turning to showers by Sunday morning. There is a 90% chance of rain tonight and tomorrow morning. Expect a low around 50°F. Rainfall totals for the approaching storm are currently projected at between 1/2" to 1" for the coast and valleys. There will be chance of showers Sunday morning (50% chance of measurable rain) turning partly cloudy in the afternoon as the storm passes to the east. Expect a high of only 60°F. Another storm will pass by to the north Monday night and Tuesday, bringing a chance of showers.
Mostly cloudy today with a slight chance of light showers, and a high of only 68°F. The chance of measurable rain for today is 20%. Tonight and Saturday morning will be partly cloudy with a low around 48°F. Saturday will be increasingly cloudy with rain likely later in the day (evening in the Temecula Valley). The high should be about 65°F; the chance of measurable rain is 80%. Morning showers will also be likely Sunday morning and the storm should clear after that. Rainfall estimates are currently 1/4" to 3/4" in coastal and inland valley areas for the upcoming storm. The snow level is expected to be above 7000 feet Saturday evening and 6000 feet Sunday morning for the local mountains. Next week it looks as if more storms will miss to the north of us; there are slight chances of rain each day.
Happy Thanksgiving! Today will be partly cloudy and pleasant during the afternoon with a high around 73°F. Look for partly cloudy conditions tonight and Friday morning with some chance of low clouds and fog and a low around 46°F. Friday will be partly cloudy as well and slightly cooler with a high of 71°F. Look for rain, heavy at times, by Saturday evening in the Temecula Valley area. Things should start clearing out Sunday afternoon. The National Weather Service's preliminary rain estimates are between 1/4" and 1/2" of rain for the coast and valleys.
Partly cloudy today with a high temperature around 79°F. Also partly cloudy tonight and Thursday morning with a low of 48°F and possible areas of fog. Thanksgiving Day looks to be partly cloudy as well and cooler with a high of 74°F. Friday is currently looking much the same as Thursday. A series of storms is predicted to miss us to the north, but by Saturday and Sunday rain will be likely.
Today will feature variable high clouds and a warm afternoon. Expect a high around 82°F. Variably cloudy also tonight and Wednesday morning with a low about 45°F. Wednesday will be much the same with a high of 81°F. Cooling in the days after that; 79°F on Thanksgiving Day, and a chance of rain on Saturday and Sunday.
High pressure is going to cause mild Santa Ana winds today which will lead to a clear, sunny day and a high around 83°F. Clear and chilly tonight and tomorrow morning with a low around 40°F. Tuesday will be warm and sunny with a high of about 83°F. The high pressure system may be breaking up by then, so don't expect any wrong way winds tomorrow. The weather will trend cooler through the weekend, with a chance of rain still in the forecast for the coming weekend.
Variable cloudy this afternoon with a high around 76°F. Tonight and Monday morning will be clear with a low of about 40°F. High pressure build back up Monday and will lead to a mostly sunny day with a high of 80°F. The rain chance in the long term forecast has been pushed back to next weekend. A gradual cooling trend should be in place by the middle of the week, according to current predictions.
Low clouds persist this morning, but later this afternoon it should be variably cloudy and warm. Estimated Saturday high 80°F. Tonight and Sunday morning will be mostly clear with patchy low clouds and fog; low around 44°F. Expect mostly sunny conditions Sunday with a high of 78°F. Longer term, things look to be cooling off approaching Thanksgiving Day and the chance of rain towards the end of next week is still in the predictions.
Today will be very much like yesterday, mostly sunny with a high of 82°F, thanks to a high pressure system aloft. Tonight and Saturday morning will be variably cloudy, with a low of 43°F. The current weather pattern will continue Saturday and Sunday, with variably cloudy conditions and highs of 82°F.

2:32pm A problem with some local internet trunk lines knocked hundreds of San Diego businesses (including this web site) offline between about 10:30am and 1:15pm this afternoon. Service has been restored! Sorry to those who couldn't get through. No weather data was lost as a result of this outage.

Sunny and warm today. Santa Ana winds are possible from the east and north east, which will keep things dry. Expect a high of 81°F. Tonight and Friday morning will be mostly clear with lows dipping down around 39°F, the coldest so far this season. Friday will be variably cloudy and continue the warm conditions with a high of 80°F. Looking ahead, the weekend looks much the same and rain is possible towards Thanksgiving next week.
Today will be a very seasonal day. Low clouds and fog this morning will give way to a mostly sunny day with a high of 78°F. It will be chilly and clear tonight and Thursday morning with a low of 45°F. Thursday will be sunny with a possibility of Santa Ana wind conditions and a high of 81°F. Looking ahead, the nights will continue to be cool but frost-free and the high pressure ridge is expected to continue through the weekend.

Apologies for the errant rain totals you may have seen on the site yesterday. My new wireless rain sensor appears to be catching interference on the frequency it was operating on. The interference triggered wild rainfall totals starting about noon until I noticed. I've adjusted the frequency and we'll see if it happens again.

It looks like the rain has come and gone; the bulk of it fell before 9 pm last night. Mostly cloudy this morning, followed by partly cloudy later today, with a high of 67°F. Tonight and Wednesday morning will be mostly clear except for patchy morning low clouds. Expect a low of 47°F. Wednesday will be mostly sunny with a high of 73°F.

The new wireless rain gauge was deployed yesterday and successfully captured rainfall from yesterday's storm. There will be a picture of it within the next week or so on the About page.

Rain is likely coming by tonight. Today will be mostly cloudy, with a high of 69°F, and a 40% chance of rain in the late afternoon. There is an 80% chance of rain tonight, expect a low of 53°F. Clearing will begin by Tuesday morning, with a 40% chance of showers, followed by partly cloud conditions and a high of 68°F.

The National Weather Service has adjusted the expected rain accumulations. We should expect between one quarter to one half of an inch in our area. The mountains may get up to an inch. Snow levels are expected to fall to 6500 feet by Tuesday morning, so there will be snow up in the mountains and snow may affect travel in some of the local passes.

Rain appears to have missed us this morning. The most we seem to have gotten here in the Temecula Valley is partly cloudy conditions. It should stay partly cloudy through Sunday afternoon with a high of 75°F. Tonight and tomorrow morning will be mostly cloudy with a low around 54°F. Monday will also be mostly cloudy with a 40% chance of rain in the late afternoon, and a high around 70°F. Rain is likely Monday night (70% chance) and is projected to end Tuesday morning.

Among the things predicted by the National Weather Service for the tomorrow's upcoming storm is snow about 7000 feet in the mountains (the first of the season) and rain accumulations up to one inch in coastal areas and foothills. Rain amounts in our area should be between one third to one half of an inch.

Weekend Update: Today will be parly cloudy, with a high of 71°F. The NWS is predicting a weak storm will miss us to the north, but we may get deepening low clouds and drizzle overnight and Sunday morning. So tonight and tomorrow morning will be mostly cloudy with a low of 57°F. Sunday will be mostly cloudy with a slight chance of rain (20% chance of measurable rain). The high should be 69°F. Looking forward, a stronger storm is predicted to reach us by Monday night, with a 60% chance of rain forecast and rainfall of up to a quarter or half an inch predicted.
The Temecula Valley seems free of fog this morning. There is patchy low clouds and fog in the forecast but it seems to have missed us today. Mostly sunny the rest of today with a high of 87°F. Tonight will be mostly clear with a low of 51°F, and low clouds and fog in the early morning. Saturday will be slightly cooler as the high pressure begins to break down; high 83°F. There is a chance of rain predicted for Sunday as a weak pressure system will come onshore.

I've bought and received a new wireless rain gauge to replace the wired one that's given me so much trouble over the past year. The new gauge features a tipping bucket design that should be highly reliable. This gauge costs as much as some of the cheaper weather stations and meets NWS specifications for bucket size. I'm hoping to run tests Saturday and have it deployed by Sunday.

2:19pm: So much for hot weather this afternoon. After heating up to 80°F, the temperature has fallen off eight degrees ... The high pressure system is weakening. The rain chance has been moved up to Saturday night (30% chance).

For the fourth morning in a row we have a fog advisory. The low clouds and fog have the effect of keeping temperatures up; otherwise morning temperatures might be plunging into the 40's this time of year. Later this morning and afternoon will be mostly sunny (with high clouds) and warmer with a high of 83°F as Santa Ana conditions develop. Expect wrong way winds and dry conditions through Saturday. Tonight and Friday morning will be mostly clear with some high clouds and a low of 48°F. Friday will be mostly sunny and wrong way windy with a high of 82°F. There should be cooling of three degrees or so on Saturday.

The new banner on this site was done by Scott Bram. Scott is also doing some forecast icons for TemeculaWeather.com that should make their debut shortly on this site.

This is the third morning in a row with a fog advisory issued by the NWS. Later today, the fog and drizzle will give way to hazy sunshine and a high of 78°F. The fog and low clouds will return tonight and tomorrow morning. Expect a low of 51°F. Thursday will be mostly sunny with a high of 84°F.
Another fog advisory starts out this morning. Yet another day to be careful driving to work (or wherever you're going). It should eventually get mostly sunny with a high of 81°F. Low clouds and fog return tonight and tomorrow morning, with a low of 50°F. Expect a mostly sunny day Wednesday with a high of 83°F.
The rain moved off quickly yesterday and was replaced by a typical, somewhat sunny November day. This morning there are areas of dense fog in the Temecula Valley. The National Weather Service has issued a dense fog alert. Take care driving this morning. Later today should be mostly sunny with a high of 79°F. Overnight will be mostly clear with areas of low clouds and dense fog in the morning and a low of 49°F. Mostly sunny Tuesday with a high of 81°F. There's no rainfall in our area currently forecast for the week.
I woke up this morning to the pitter patter of light rain. That's funny, I didn't even see that in the NWS forecast yesterday morning (that's because it wasn't). It's there now! People will probably be staying mostly indoors today because the rain chance through today is 80%. It looks like all the rain should be gone by tonight. The high temperature will be only 65°F. Tonight will be mostly cloudy with a low of 57°F. Monday will be partly cloudy with a high temperature of 82°F.

The NWS San Diego office publishes something called the forecast discussion twice a day. It has detailed information about developing weather conditions, rather than the straight forecasts that are a part of their Inland Empire forecast and which you see adapted here to Temecula. Perhaps the threat of rain was detailed in the discussion, which I read occasionally but did not Saturday morning. The current discussion predicts this weak storm will quickly move on and be replaced by weak high pressure the rest of the week.

Weekend update: Mostly sunny later today with a high of 78°F. Increasing high clouds tonight and a low of 50°F Sunday morning. It's interesting that low clouds and fogs aren't in tonight's forecast. For Sunday, expect variable high clouds and a slightly warmer day, with a high temperature of 80°F.

For the next few months, overnight temperatures for the most part are going to be in the 40's. The mornings are starting to get a little cold. It's normal in December and January to have low temperatures in the 30's. The high temperatures should continue to drop through November and December as well. the Temecula area can have frosts, but they don't occur very often. Last year there were only a handful of them.

More low clouds and fog this morning; again, be careful driving. Variably cloudy later today with a high of 80°F. Mostly clear tonight with low clouds Saturday morning and a low of 48°F. Saturday will be a mostly sunny and a little warmer with a high of 82°F.
Foggy with low visibility in the Temecula Valley this morning. Be careful on the road this morning. Later today, it will be mostly sunny with a high of 77°F. Mostly clear also tonight and Friday morning with low clouds late and a low of 50°F. Friday will be much the same as today, mostly sunny and a high of 77°F. It looks like this mild weather pattern is going to continue into the near future.
Halloween forecast: The scattered rain and showers has missed to the north. Today will be partly cloudy with a high of 74°F. Tonight will be mostly clear, with patchy morning fog Thursday morning and a low of 53°F. Slightly warmer and sunny Thursday, with a high of 78°F.

It should be in the 60's for trick-or-treating tonight.

The clouds did not show up yesterday as advertised, and the forecast was badly off as a result. Today's forecast calls for increasing clouds and a 40% chance of rain late in the afternoon. The high today should be around 72°F. Tonight will be cloudy with a 60% chance of showers and a low of 56°F. Partly cloudy Wednesday with a high of 75°F.

The Hourly Summary page now shows current conditions as well, and is now updated every ten minutes like the main page. I will be working to get rainfall in there so people can see when the rain fell.

After yesterday's blown forecast we hope to get it better today. Low clouds this morning, and mostly cloudy today, with a high of only 66°F. Tonight and tomorrow morning will be cloudy with low clouds and fog; low 56°F. The chance of rain is now 30% on Tuesday, which will have a high of 62°F. It looks like we'll make it though today without rain. 20% chance of rain is currently in the forecast for Wednesday as well.
Sunday: Areas of low clouds and drizzle this morning, followed by variable high clouds this afternoon and a high of 73°F. Tonight and monday morning will feature more lows clouds and drizzle, with a low of 56°F. Increasing clouds Monday afternoon with a high of 72°F. A 40% chance of rain is forecast for Monday night, and the rain chance is even higher (50%) on Tuesday.
Weekend update: Today will feature variable high clouds and a high of 79°F. Tonight will be cool with patchy low clouds and fog late and a low of 49°F. Partly cloudy and cooler Sunday with a high of only 72°F. Looking ahead there is a developing low pressure trough over the ocean which will begin to move ashore and inland on Monday, dropping temperatures, increasing clouds, and leading to a slight chance of rain on Tuesday.
Friday looks like it will be very similar to both Thursday and Wednesday. Except that there's no fog advisory from the National Weather Service this morning. Today will be mostly sunny with a high of 82°F. Tonight and Saturday morning there will be areas of late night low clouds and fog, and a low of 50°F. Saturday will be variably cloudy and slightly cooler with a high of 78°F.
Very much like yesterday for Thursday. Including the fog warnings, which have been repeated this morning. Visibilities are going to be very poor at times, so be careful. Mostly sunny later today with a high of 83°F. Late night clouds and fog tomorrow morning with a low of 49°F. Friday is predicted to be much the same as today, mostly sunny with a high of 82°F.
Fog warning: Drive very carefully this morning. The National Weather Service has issued a fog advisory and visibilities are not good outside. Later on today it will be mostly sunny and windy with a high of 83°F. Mostly clear tonight and tomorrow morning with a low of 51°F. Thursday will be mostly sunny and windy as well with a high of 84°F.
Yesterday we received our first measurable precipitation in a long while, courtesy of some drizzle. There are low clouds once again this morning, which will give way to a nice sunny day with a high of 80°F. Tonight and tomorrow morning will be mostly clear with a low of 56°F. Sunny again on Wednesday, warmer, and windy in some areas with a high of 84°F.
There are low clouds and fog this morning, so be careful on the roads. It will be mostly sunny later on with a high of 78°F, well below normal. More low clouds tonight and Tuesday morning with a low of 54°F. Expect a warmer, mostly sunny day on Tuesday with a high of 88°F.
Sunday update: Variable cloudy today, and sprinkles are possible. Expect a pleasant high around 77°F. Overnight there will be low clouds and drizzle, and a low of 54°F. Monday will also be partly cloudy with a predicted high of 77°F.
Weekend outlook: Saturday will be partly cloudy with a high of 84°F. Mostly cloudy with a few sprinkles (!) tonight and Sunday, according to the National Weather Service. Sunday's low will be around 53°F and Sunday's high will be around 80°F.

The National Weather Service's San Diego office is now incorporating data from TemeculaWeather.com's weather station into their forecasting! I received an email message yesterday to this effect. They mentioned that they have little real time data from the southern Inland Empire, so our data will help them produce a better forecast.

Friday forecast: Today it will be mostly sunny with some high clouds and a high of 88°F. Expect a partly cloudy night with areas of low clouds and fog, and a low of 50°F. Saturday will be much the same, sunny with a high of 87°F. The National Weather Service is predicting that Sunday will be as much as ten degrees cooler, so it should be a pleasant autumn weekend.

My internet service provider from the house had difficulties for a couple of hours last night (from 8pm to 10pm or so) and the weather data was stale for a while. That was the first service interruption in more than two months; a pretty good run.

Variable high clouds are again in the weather pattern for the next few days. Expect a slighly warmer high today of 88°F. The low tomorrow morning will be 49°F with patchy morning low clouds and fog. Variably cloudy again on Friday with a high of 87°F.

I expect to have the email list up and running soon, possibly later today!

A few low clouds this Wednesday morning. There will be variable high clouds today and it will be cooler, with a high of 84°F. This will be followed with possible low clouds tomorrow morning and a low of 51°F. Tomorrow should be very similar to today, with variable high clouds and a high of 84°F. The National Weather Servie is predicting it will get a little cooler through the weekend.
Low clouds this Tuesday morning are holding the pre-dawn temperatures in the mid-50's. Later today it will be partly cloudy with a high of 91°F. Tonight will also be partly cloudy with the low tomorrow morning around 56°F. The National Weather Service is predicting Wednesday to be much cooler; partly cloudy with a high of 82°F.
Monday update: The National Weather Service is now predicting the heat will last another two days; today will not be cooler as predicted yesterday. Expect sunny skies and a high of 93°F today. Tonight will be partly cloudy with a low of 51°F. Tuesday will be partly cloudy during the day with a high of 91°F.
Sunday update: Not as warm as yesterday's forecast. We'll probably see a high of 90°F later this afternoon under sunny skies. Tonight will be mostly clear with a possibility of low clouds late and a low of 53°F. Mostly sunny and much cooler Monday with a high of 84°F.

A story about this web site appears in the Sunday edition of The Californian, an edition of the North County Times. You can read the text of this story online. I'd like to thank John Hunneman and The Californian staff for noticing this site and taking the time to publish such a nice story.

Weekend outlook: Clear, dry, windy and warm with cold mornings. More wrong way winds gusting as high as 30 miles per hour today. Temperatures will top out today around 93°F. The low tonight will be near 50°F. Look for even higher temperatures on Sunday, with a predicted high of 95°F.
There's a few low clouds in the Temecula Valley this morning. They will give way to Santa Ana winds and dry heat later today. For those that don't know, this means wrong way winds (from the east or northeast) of up to 30 or 40 miles per hour and uncomfortably low humidities. These conditions are common this time of year and can lead to dry, cracked skin. It will be mostly sunny, and the high should be around 90°F. Overnight it will be mostly clear with a possibility of low clouds late and a low of 49°F. The Santa Anas will continue Saturday with strong winds at times and an even warmer high of 93°F.
Late forecast today, sorry. Yesterday was warmer than the forecast anticipated, and today looks like it may be a little warmer still, sunny and a high of 88°F. Tonight will be clear and cool with an overnight low of 50°F. Tomorrow will be even warmer with a high of 91°F.
Only a few low clouds this morning, giving way to a warmer day than the last couple. Expect a high of 81°F, still well below normal for this time of year. Conditions tonight will feature some low clouds with a low temperature of 54°F. Thursday will be mostly sunny and warmer with a high of 86°F.
Low clouds once again this morning. They will give way to a mostly sunny afternoon with a high of 76°F. Tonight will feature low clouds yet again and a low of 56°F. Look for mostly sunny skies again Wednesday with a high of 79°F as we start into a predicted warming trend.
Just a little bit of low clouds this morning. This afternoon will be mostly sunny with a high of 80°F. Tonight will be partly cloudy with low clouds and a low of 53°F. Tuesday looks to be very much like today; mostly sunny and 80°F once again.
Late forecast today. Today is shaping up to be a very nice day, mostly sunny with a high later on of 74°F. The National Weather Service forecast is currently missing, so tomorrow is tough to forecast, but the low tomorrow morning should be around 56°F, with low clouds. Enjoy the nice weather!
Today should be mostly sunny after the low clouds clear with a high of 82°F, continuing the downward trend in temperatures we've seen this week. Look for low clouds tomorrow morning and a low of 56°F. Saturday will be clear with a high of 79°F.
Hmmmm. The NWS forecast is missing again this morning, for the second time this week. We are definitely into a cooling trend, though. The effects of Hurricane Juliet are gone as well. It's clear this morning, and it'll be mostly sunny today with a high of 82°F. Tonight will be clear with a low of 56°F tomorrow morning. Expect even cooler temperatures tomorrow with a high of 77°F.
This morning is mostly clear and not as cool as predicted. Today will be sunny with a high of 88°F. We are going into a cooling trend according the National Weather Service and should drop 5 degrees per day through Friday. The weekend outlook looks nice with temperatures in the 70's. Tonight will be mostly clear with a low of 56°F, and tomorrow will be mostly sunny with a high of 84°F.
Sorry for no forecast this morning. The National Weather Service Inland Empire forecast, on which this forecast is based, was missing. Tonight will be clear with a low of 56°F. Tomorrow will be mostly sunny and finally cooler with a high of 88°F.
Humid, hot and partly cloudy today with a 20% chance of showers or thunderstorms. The high today should be around 98°F. Overnight it will be partly cloudy with a low of 65°F. Tuesday looks to be partly cloudy with a high of 94°F.
Very hot and partly cloudy today, with a high of 100°F. Tomorrow morning's low will be 66°F, a warm low for this time of year. Tomorrow's predicted high is 97°F under partly cloudy and unusually humid conditions. The reason for the humidity in tonight's and tomorrow's forecast is the breakup of Hurricane Juliet off of Baja California. It will influence the weather pattern even this far north.
This is a late update for Saturday. Today is sunny, and the high today will likely top out around 93°F. Tonight will be clear with a low of 56°F. Tomorrow will be partly cloudy and warmer, with a high of 98°F. I'm somewhat suspicious of tomorrow's forecast, but that's what the National Weather Service is saying.
Sunny and hot again today under clear skies. Expect a high today of 94°F. The low tomorrow morning should be around 59°F. Saturday is predicted to be warmer with a high of 98°F.
The heat continues today with another sunny day and a high of 95°F. Similar conditions are predicted all the way into the middle of next week, according to the National Weather Service.
Yesterday was the fourth triple digit day of the year. Today will also be sunny and hot, with a high of 98°F.
Get ready for another scorcher. It's fall, but we're definitely experiencing summer weather. It will be sunny today with a high of 99°F. The National Weather Service is predicting highs in the 90's until Friday this week.
Low clouds abound this morning, to be followed by another sunny, hot day. Expect a high temperature around 94°F. This weather pattern is predicted to hold the entire week ahead.

2:30 pm So much for today's forecast. Today is only the third day above 100° in Temecula so far this year. Today also features the highest temperature of the year to date. The humidity is very low, but it sure is baking outside.

Once again the NWS is predicting sunny and hazy conditions. I'd been perplexed by this, since Temecula was not experiencing any hazy conditions, until yesterday. Yesterday morning I drove up to Ontario and noticed that the San Bernardino valley had those hazy conditions. So, today will be sunny once again with a high around 91°F.
It's warmed up quite a bit into the 90's, and the weather patttern is expected to last into the weekend. Due to the time of year, low temperatures are now falling regularly into the 50's at night. This is the time of year, in the fall, where the largest differences between high and low temperatures occur. Today (Saturday) is predicted to be sunny and somewhat hazy with a high of 93°F. Similarly, Sunday will be the same with a high of 92°F.
The NWS is forecasting a hazy day, but this morning it is relatively clear and cool. We should see a high much like yesterday around 87°F.
Low clouds and ground fog this morning in the valley. Be careful driving this morning. This afternoon will be mostly sunny though with a high of 87°F.
Another late forecast, but the weather today will be a lot like yesterday. The low clouds and fog have burned off at this point (9am) and we are headed for a mostly sunny day and a high of 84°F.
More low clouds and fog this morning, then it will become mostly sunny once again with a below normal high of 86°F.
Low clouds and fog are back this morning. It will be mostly sunny later today with a high of 82°F.
Today it will be sunny with a high of 87°F. It's even clear this morning, which means temperatures are dipping down into the 50's.

Today I'm unveiling the wireless version of our site, which can be accessed on most internet-capable cellular phones with mini-browsers. If you have a phone that supports a wireless standard called WML, you can now access current weather information wherever you are on your cell phone. If your cell phone mini browser supports a "goto url" function, just type in temeculaweather.com for a mini, text only version of our site.

I'm also unveiling advertising today. If you have a local business and are looking to reach a growing online audience of local residents, visitors, and people looking to relocate to the Temecula Valley, consider placing advertising on the Temecula Weather pages.

Mostly sunny today and a little warmer than yesterday, with a high temperature of 96°F. Sunday is predicted to cool a couple of degrees.
The NWS forecast is predicting a partly cloudy day today and continued very warm conditions. Clouds means the humidity will be higher than normal. Expect a high temperature today of 93°F.
Apologies for the late forecast today. I've been on travel in the San Francisco bay area and had trouble getting back due to commercial aircraft being grounded. I drove a rental car back last night and made it in late. Again, my deepest sympathies to and prayers for the victims and their families and friends of Tuesday morning's acts of war. I (and I imagine everyone) remain deeply troubled by the attacks.

In Temecula today, conditions are already sunny, and the high temperature should be around 87°F.

Our nation yesterday suffered the darkest tragedy in recent history. Not since the attack at Pearl Harbor has there been such a devastating attack on our country. All of us who watched the new reports were mesmerized and helpless as our passenger jets with our people on them slammed into buildings in New York and Arlington, Virginia where thousands of people were at work. We watched as the twin towers of the World Trade Center sighed and crashed to the ground, with thousands entombed inside.

My heartfelt condolences go out to the thousands of victims and their families. I pray for all them in this time of shock, sorrow and anger, that they will have peace and that they will be consoled.

In Temecula today, it will be sunny on this day of reflection, following fog and low clounds this morning, with nice temperatures around 83°F.

The NWS forecast for today is calling for the usual low clouds and fog this morning, followed by a hazy afternoon. The high temperature today should be 79°F.
Okay, something a little different today. We'll start with the same low clouds and fog we've been having, but the NWS forecast is calling for hazy sunshine after that. And cooler. The predicted high temperature for today is only 76°F. Partly cloudy conditions are predicted for Tuesday and Wednesday, and cooler still.
Temperatures today will continue to be well below seasonal norms, with a high of 81°F. It seems like we've been having the same weather forecast for days and days now, with low clouds in the morning and sunny afternoons. This afternoon will be very pleasant in the Temecula Valley.
It looks like today will bring more of the same, with morning low clouds and a sunny afternoon, and a high of 81°F, which is well below normal for this time of year. It may warm five degrees or so on Sunday.
More low clouds and fog this morning. According to the NWS forecast, the rest of the day should be sunny with a high around 85°F. But then, that forecast was wrong yesterday ... It looks like pretty much the same weather (with temperatures slightly below normal) through the weekend.
There is fog in parts of the Temecula Valley this morning; please be careful driving. There will likely be some dew this morning. The low clouds and fog will burn off quickly and the rest of the day will be sunny with a high around 88°F. Yesterday afternoon ended up being partly cloudy, against the NWS forecast, so that was something of a surprise. The forecast currently calls for a warmer day on Friday.
Once again, according to the NWS forecast, patchy morning clouds and fog giving way to mostly sunny by mid-morning or so, with a high temperature of 91°F.
Looks like some low clouds and fog to start today, followed once again by mostly sunny skies and a high of 89°F. Similar conditions are predicted for tomorrow; a warming trend is in place through Friday.
Enjoy your Labor Day! My update is late for today (11:30am), but today started with fog and is turning mostly sunny. There are some clouds, though, and humidity is higher than normal. It looks like temperatures will top out at 88°F later today.
Thunderstorms are predicted for parts of the Inland Empire today. While it's unlikely that they will get as far west as the Temecula Valley, we'll be able to see the thunderheads to the east and we will also be more humid than normal. It will be mostly sunny today with a high of 90°F.
Sunny again today and a little warmer with a high of 88°F. Have a good Labor Day weekend! Sunday and Monday, according to National Weather Service, will be very similar.
The weather warmed up much more quickly than forecast yesterday. According to the latest forecast, today will be sunny with a high of 86°F, slightly warmer than yesterday. Days pretty much like to today are forecast throughout Labor Day weekend.

Yesterday also marked the one year anniversary of the first visit to this site. Since then there have been over 36,000 visits. Thanks for making TemeculaWeather.com a success!

Yesterday was only the second day under 80°F this summer (July 17th was the other, with a high of only 78.3°F). Today is predicted to be the third, with a high of only 77°F. Low clouds and fog are featured again this morning, but will give way to mostly sunny conditions. Temperatures are supposed to warm slightly tomorrow but the high should again be below 80°F.
Temperature cooled much quicker than the NWS (and my forecast based on it) expected yesterday. Today is starting very cool for this time of year with low clouds and fog in the Temecula Valley. After the morning clouds are gone, today will be mostly sunny with a high of only 80°F.
Sunny again today, and likely slightly cooler, with a high of 94°F. Temperatures may fall down into the 80's on Wednesday. We are having slightly warmer than normal temperatures for late August. The change from the hotter days earlier this month are that it's been drier and that the lows have begun to trend down into the upper 50's and lower 60's, even on hot days.
Yesterday featured little of the normal westerly wind and got very hot. Today will again be sunny and hot, with a high of 97°F. The NWS forecast shows some easing from here, cooling a few degrees per day into Wednesday. Note that the normal temperatures are down for this period in August. We've experienced some unusually cool weather in this stretch over the last couple of years, including a high last year on August 29th of only 69.5°F, the coolest summer day we've recorded.
The forecast is a little late today. Look for a high of 94°F under sunny skies. The overnight low will be around 60°F. Sunday should be warmer still and mostly sunny with a high of 96°F as high heat returns. I'm going to move these forecasts up into the forecast area of the page when I get a chance. Note that these are not scientific forecasts, but they are based on the NWS Inland Empire forecast and past patterns of where we've ended up in their temperature range.
Well, I sure missed the mark yesterday. Forecasting is tough. Based on the NWS forecast today, I think we'll see a high of 89°F. It will again be mostly sunny!
The unseasonably cool weather we've experienced the last couple of days is going to continue today. There are low clouds again this morning, and that will give way to a mostly nice, sunny day. The high today will be around 83°F, based on the NWS forecast. Wind will likely start today by 11am and continue a little past dusk tonight. A warming trend is predicted over the next several days, so look for warmer temperatures tomorrow.
It seems we're in for a day very similar to yesterday. The high temperature today should be around 82°F, a very nice cool summer day with lots of sun. Expect to see the winds start early today and they will likely hang around after dusk tonight.

I should point out again that all I'm doing here is customizing the NWS forecast to the local area, based on my observations for this summer. I was two degrees too high Monday and three too high yesterday; I don't think that's too bad, and I think today may be even closer.

Based on the NWS forecast, I think we're in store for a high of just 85°F today, well below normal. It looks like tomorrow will be similar as well. There are some low clouds this morning; they should be gone by mid-morning and conditions should be mostly sunny.
Expect high temperatures to be reduced the next couple of days, according to the NWS forecast. We're going to get a break from last week's high heat. Based on that, I think today's high will be 88°F or possibly 89°F. Humidity continues to be lower the last couple of days and I think that will continue today.
The wind kicked up early today, and as a result it's possible that today might turn out a little below normal, which is against the forecast. If you are interested in what's normal in Temecula, check out the new climate page. It's recomputed nightly and tracks normal highs, lows and average temperatures for the months of the year, including August, which is the hottest time of year around here.
The high heat is expected to continue into the near future. Today is featuring low relative humidities and the lack of water content in the air does not bode well for this afternoon. The National Weather Service is predicting highs of 98°F to 108°F in the Inland Empire today. If this forecast is right, Temecula will be in the lower end of this range.

Yesterday's high of 100.5°F was the warmest of the year to date, and the first official triple digit high of the year. This is the latest in the year that I can remember the first hundred degree day occurring. On an average temperature basis, July 4th remains the warmest day this year.

HEAT ALERT! The 100° weather watch is on, and I don't think we're going to escape this time. Temperatures have been well above normal all morning. We'll see in the afternoon. Stand by ...

5:18 pm Today's high was 99.9°F, which many saw rounded up to 100°F on the web site this afternoon. That won't do it for the archive, which uses the extra digit of precision and will not remember today as a hundred degree day. More high heat is predicted for tomorrow.

I've now placed a normal temperature calculation for the current weather report directly below the current temperature. This should give visitors a quick indication of how close to normal the current conditions are. Note that last year at this time was characterized by blistering hot days, so that accounts for the normal temperatures being so high in the afternoon.

Lost four hours of data when the processing computer locked up very early this morning. I am about to add a 36 hour summary, so unfortunately the data gap will be visible in that table.

8:57 pm The 36 hour summary has been added to the site. Note that rainfall is missing from it for the time being. New to the summary are normal temperatures, winds, humidity and dewpoint for times of the day. These are calculated on an 11 day moving average just like the normal high and low on the main page. Please let me know what you think.

At noontime a connectivity outage from the house continues. It started just after 2:30am. I'm working on getting an alternate connection going; there's been too many problems recently with the ISDN connection.

2:41 pm Connectivity restored. And this was after I did quite a bit of work to get a backup modem line to do a one time dial and update the site. The modem link's success shipped the last 1400 records to the site only twenty minutes ahead of ISDN service being restored.

Today may be the first 100° day of the year. At this writing, the temperature is already 94°F at 11:30am. It has heated rapidly over the past few hours from a warm low of 67°F this morning. The wind has started for today (and will continue until dusk), so the temperature will not rise as quickly in the afternoon, but we could see the temperature spike above 100° sometime between 2pm and 4pm. Stay tuned.

4:51 pm Today flirted with 100°F, topped out at 98°F, and has slid back down. Today's high is the highest temperature recorded so far this year, and will likely be the highest average temperature when it is done as well (currently July 4th is the warmest day of the year with an average temperature of 81.7°F), due to the early heat today. The all-time highest average temperature of 85.2°F occurred September 16, 2000.

Some minor improvements have been made to the web site. A few days ago I got the pressure trend arrows operational. Also, as of today, the wind gust speed indicated on the site is for the last ten minutes. Before it was only a 30 second indicator.
Internet connectivity problems are resulting in data delays to the web server this morning.

1:29 pm Problem resolved: The internet service provider has reported routing problems that are now fixed!

The weather has warmed up to normal summer conditions, and they are predicted into the near future. This means high temperatures in the mid 90°'s and low temperatures around 60°. Still no very hot days this summer to date, but stay tuned.
The summer continues to be very mild to date. Yesterday's high was only 78.3°F and was the coolest July day on record. Yesterday also featured morning marine layer, something that is usually absent this time of year. Last year about this time is when things really started to heat up, so enjoy the nice weather while it lasts!
Is this summer? Closing in on noon today the temperature is only a balmy and very springlike 75°F. If today finishes below 80°F (that would be against predictions, by the way), it would be the first July day under 80°F in the two year data history of TemeculaWeather.com. In the past two years, there have been very few sub-80°F summer days: three in August, 2000 (including a high of only 69.5°F on August 29, 2000), one in September, 2000, and three in September, 1999 (including a high of only 67.9°F on September 18, 2000, which is the coldest summer day on record).

1:55 pm Over 80: And this day won't be one of them!

Service problems are resolved for now as of this morning. Scattered thunderstorms earlier today brought some spattering from the skies. We usually get only one or two bouts of this type of weather per summer. The National Weather Service is predicting this pattern will be around for a couple more days or so.
Happy Birthday America! Cloudy, muggy and very warm today. Yesterday even brought some scattered thunderstorms. For the record: last season's total rainfall was 11.33". This is only from November 8th on, however. The rain season just started will be the first July to July season we have data for. The internet service problems from the house continue. I'm currently holding the connection open until the service provider fixes some router problems. Yesterday's and this morning's live results were disrupted by the problems.
Yesterday's average temperature of 77.7°F was the warmest day of the year to date, and is just a harbinger of things to come this summer. Average temperatures will be in the 80's on many days this summer. The latest heat has been accompanied with unusual humidity. The heat index attempts to factor in humidity, and even with the relatively high humidity, the heat index is still registering lower than the air temperature in the middle part of the day.

1:09 pm Mid-day problems: Looks like connectivity problems from the house to the server. The weather data is more than one hour out of date at this point.

Welcome to summer (solstice occurred yesterday). The spring pattern was broken eight days ago and every day since has been in the 90's. Still no hundred degree days yet, but they will be coming. I'm still working on the barometer change arrow, which should be done any day now.
Uh oh. I woke up this morning to no clouds. It's already warming quickly. This would appear to be the end of our cooling trend.
The web server machine was upgraded today, and complications surrounding the upgrade caused down time of about four hours. No data was lost, and things are back up and operating normally.
We seem to be cooling from normal late spring weather patterns at the moment. The National Weather Service is forecasting more cooling for tomorrow, but we'll see if that happens or not. In other happenings, I'm currently working on a barometer change arrow which should be done by the end of the week.
Interesting how wrong the weather forecasts can be, huh? Last week there were predictions of 100° heat in our area and the highest we got was 92° on Thursday. And then it cooled right off.

Some people refer to the weather patterns we see this time of year as "June Gloom". June typically has lows in the upper 50's, held up by marine layer (low clouds). The marine layer also holds the daytime highs down. This far inland (Temecula is approximately 20 miles from the coast), the layer is thinner and usually burns off by midmorning. Then Temecula heats up for the rest of the day. Around dusk, you can see the marine layer coming back in from the west, hugging the hills and belching through the Temecula gorge (which the Santa Margarita river flows through to the ocean). It is a strange, unique sight. The marine layer pattern usually breaks by July. Last year was an exception; the pattern lasted into mid-July. When this pattern does finally break, summer conditions will begin.

After last week's run short of 100°, near record heat is predicted to return today and tomorrow. June and the first part of July last year were unusually cool; this year summer looks to be arriving early.
12:14pm - Unless the wind picks up, Temecula is going to have its first 100° day of this year. In a normal year, there are between 12 and 25 hundred degree days. There were 18 such days in 2000. Hundred degree days are possible in May, but not probable. Last year's first 100° day did not occur until July 18th!

The wind did indeed pick up, and temperature did not reach 100°.

An obscure software error caused processing from the weather station to stop today for about four and a half hours. The problem is corrected and won't cause processing to stop again when it occurs, but it's amazing that this problem took nearly two years to surface! Apologies to those who looked at the site this morning hoping to see up to date weather.
The weather is starting to follow the late spring pattern of highs around 80°F and early morning clouds. Today I added the National Weather Service wind chill calculation onto the main page. The wind chill is the apparent temperature as the wind hits the skin. As with the heat index, the wind chill values for Temecula aren't likely to be dramatic. Perhaps next winter we might see some values in the twenties...
H-O-T! Today I completed heat index calculations, which are now on the site. The heat index is a misery formula derived from the air temperature and relative humidity. In the summertime Temecula may experience rare days when the comparative heat index temperature is pretty high (which happens when the temperature and humidity are both high). Normally, however, humidity is low when it is hot and that will mean most of the time the heat index will be at or below the air temperature.
The weather is starting to fall into typical springtime patterns. We're having some warm days, but most days have been nice with low clouds in the morning and afternoon sunshine. An ISDN glitch yesterday morning caused the web server to fall ten hours out of date. Today the IP address of the web server has changed. The result should be quicker loads for those of you with higher speed connections.
Added today is wind gust speed. This is tabulated every thirty seconds, and is the highest wind speed recorded in that time. In the future I may increase the amount of time for computing the wind gust. The wind speed and direction are thirty second averages. Warm weather is coming -- the next couple of days are predicted to be in the 80s and may even reach the 90s. And this only days after a chilly winter-like storm passed through the area.
Data from the barometer is finally online. Interestingly enough, the barometer is the pressure that corresponds to pressure at sea level. This is done so that the pressure can be compared to other reported pressures at various elevations. The mean pressure at sea level is 29.92 inches hg (hg is scientific notation for the element mercury which was used in early barometers to measure air pressure). Since Temecula is a little over 1000 feet above sea level, the air is a little thinner and the actual pressure should be about one inch lower. But you will never see the actual air pressure reported that way and we follow that convention here.
Still waiting for the barometer. A bug related to the daylight savings time switch last week caused rain and archive results for this month to often be off. Essentially a day would be missing from the calculations. The calculations have been fixed to take daylight savings time into account. Meanwhile, the weather has taken a very cold and stormy turn for April, with high temperatures well below normal.
I've ordered the final sensor, which is a barometer. Actually, getting a barometer involved upgrading the Ultimeter 800 to a Ultimeter 2000. The upgrade should arrive later this week, and I hope to have barometric readings up shortly thereafter. I'm still working on getting the National Weather Service forecasts directly on the site; it will be part of a page redesign I hope to do soon.
Wind information is now on the site! I completed mounting the sensor on top of my chimney, and worked out some software problems translating the information from the sensor. I'm not 100% sure it's bug free yet, but it's now on the site. The addition of wind information means it will be possible to compute wind chill, although that is not a major factor for Temecula (just as the heat index is not a major factor for the area since a typical hot day features low humidity).
The web server was affected by this evening's rolling blackouts, a consequence of the recent heat and a fire at a Southern California power plant that took it down this morning. Yours truly accidently hit the off switch in the darkness instead of the mute switch on the UPS that was supposed to keep it on through something like this, and the UPS battery couldn't supply enough wattage to reboot the computer. The surge wattage required at startup is more than the normal load, which the UPS is designed to handle. So, as a result, the site was down between about 6:20 pm to around 7:20 pm while our San Diego office was pitch black. Data collection continued like normal, though, and Temecula appeared unaffected by this round of rolling blackouts. In case of one, though, the data collection computer attached to the weather station also has a UPS and has been tested to survive almost two hours on battery power.
The latest storm has arrived. The forecast is for a light storm without a lot of moisture, but so far that hasn't been the case. Today I deployed the new relative humidity and temperature sensor, and other new equipment purchased (including the RF filter and the new junction box). The National Weather Service has granted permission to put their forecast directly on the site; this will take some work and may not happen immediately. I also plan on putting up the dewpoint temperature very shortly.
We're currently waiting for a storm to hit from the north. This storm originally was supposed to hit us Saturday, actually sent some sprinkles through yesterday, and may finally get here this afternoon sometime. Or maybe not. In other news, I've asked permission from the U.S. Weather Service to use their forecast data on this site. Stay tuned ...
Three days of fairly steady rain, showers and even hail. The latest series of storms has delivered more than two inches to date and there may be some more. One caveat is that these storms have been warmer than those in the recent past. A warmer storm usually means more rain potential. I received the combined outdoor humidity/temperature sensor, but I just found out that there is a more expensive solar shielded model that would be ideal instead. So we wait. I would not have been able to install the new sensors anyway under the current weather conditions.
TemeculaWeather.com is now featured on the City of Temecula website in two locations! The city had asked my permission to add a link to this site a few months ago and it took until recently to accomplish that.
A outdoor humidity sensor has been ordered today. It should arrive in a week. I think the fake rainfall readings that we get occasionally are coming from the junction box of the weather station so I've ordered a replacement for that as well. I've also ordered an RF (Radio Frequency) filter to cut down on any interference in the instruments from radio tranmission sources.
Happy Valentine's Day! Snow is back impressively on all of the mountains in the region, including Agua Tibia. My January picture does not do it justice. It seems so close when you can see the individual trees (or what used to be trees before the fire) on the mountain. Get a look at it in the next day or so as you drive around town. It is impressive!
Lots of rain in the last 24 hours. Since yesterday morning, there's already been more than one inch total (with a brief break in between last night) and the rain continues into today, heavy at times. Although nothing like the overnight torrent we experienced in January. Our rainfall totals haven't been anything like those experienced in the L.A. basin, either (4" in some locations). I've added monthly rainfall to the site and I hope to have seasonal rainfall up shortly (although for this season it will be incomplete since we started recording last November).
The heat wave is diminishing. We went from a cold January to a very unseasonably warm first part of February, with temperatures in the upper 80s and 90s that aern't uncommon in May and June. But, not only will today be much cooler than the past few days, there is also some chance of showers later tonight. And with the weather pattern changing, there isn't much chance of the warm temperatures returning anytime soon.
I've added a short story about the Agua Tibia snowfall.
Yesterday's average temperature of 40.6°F is the coldest since we began recording by a few degrees! Actually, most of the coldest days (all of the top six) have occurred this month. The previous coldest day was January 17th, with an average temperature of 44.4°F. See this month's records for the chilly details.
We are currently being visited by a very cold storm, one of the coldest I can remember here. 35°F for a low is a very cold low for cloud cover. There is a threat of hail with temperatures like they are.
The current monster storm has dropped nearly 2" of rain on us overnight. We had technical difficulties earlier this morning that are now corrected.
Rain! Boy do we need it.
Dramatic weather change in the last 24 hours to overcast and cloudy. The very dry weather continues. Temecula ordinarily (according to other sources) receives about 12" of rain in a season. We may only have about an inch of that by now (the season begins on July 1).

The Temecula weather pages are a service of WeatherCurrents. Temecula, California is located in the Temecula Valley, in southwestern Riverside County, along the Interstate 15 highway. The Temecula Valley's rolling hills are home to the Temecula wine country, vineyards, golf courses, a casino resort, and Old Town Temecula.
