A low pressure system has brought cooler, slightly damp weather to the region late this week, even resulting in measurable precipitation in some locations - a very rare occurrence during what is typically one of the driest months of the year on average.

A deep marine layer, with multiple levels of stratus, brought scattered patches of light precipitation to parts of the region - still ongoing as of early Saturday morning. As of this writing, WeatherCurrents' station in Beaumont (Cherry Valley) has recorded the greatest amount of precipitation since Friday, totaling 0.20 inches. This is followed by 0.12 inches in De Luz. Northwest of Beaumont, a total of 0.05 inches was reported in East Highland (courtesy of Peter Michas). South of De Luz, Fallbrook recorded 0.08 inches through early Saturday morning. Other totals included 0.05 inches in Riverside's Orangecrest suburb, 0.10 inches in Temecula Valley's Wine Country (courtesy of Jim Sappington), 0.08 inches in Yucaipa (courtesy of Don Kramer), 0.03 inches in Moreno Valley, 0.02 inches in south Temecula, and 0.01 inch in both Anza and East Hemet. A trace of rainfall was observed in Central Murrieta.

Mountain ranges and foothills have been more prone to seeing higher, although still not significant precipitation amounts. The trough is forecast to exit the region by Monday as the weather pattern shifts to warmer, drier offshore flow. A brief ridge of high pressure is expected to build mid-week before another trough enters the region, bringing down temperatures to below normal once again.

Here are the rain totals for the WeatherCurrents network and associates as of 9 AM Saturday:
