A low pressure system from the north brought cooler weather and rain to parts of the region this week, mainly Thursday night into Friday morning.

Significant rains fell mainly in Los Angeles County and more northerly locations, particularly along coastal-facing mountain slopes. Simi Valley received 1.06 inches, taking a major lead in WeatherCurrents totals from the storm. Lake Elsinore was the only other WeatherCurrents station to see any significant accumulations, with a stationary area of precipitation over a portion of the Santa Ana Mountains extending into northern Lake Elsinore producing 0.86 inches there. The storm's southwest flow likely contributed to a major rain shadow being cast over much of the Inland Empire valleys, with virtually no meaningful precipitation falling in most inland areas east of the Santa Ana Mountains. Moreno Valley's total of 0.33 inches was potentially aided by the station's location along the south-facing slopes of Box Springs Mountain. A modest total of 0.31 inches fell in South Fallbrook. In Temecula Valley's Wine Country, a total of 0.14 inches was reported (courtesy of Jim Sappington), matching totals in South Temecula and Northwest Murrieta. Elsewhere, precipitation totals were meager at best and fell short of predictions. The driest communities were East Hemet and San Jacinto, which both received totals of only 0.02 and 0.01 inches respectively.

Residual moisture had mostly left the region by Friday night. Following drier weather with offshore flow this weekend, a trough passing over the region Monday and Tuesday could bring chances for additional precipitation, with a focus on San Diego County. A more significant storm could bring widespread rain late next week, but details remain uncertain.

Here are the rain totals for the WeatherCurrents network and associates:
