Several weak low pressure systems brought a break this week from what has been an unusually warm, dry winter up to this point.

Cool weather arrived Monday as a cold air mass descended over the region, bringing cold low temperatures Tuesday morning. Rain did not enter the region until Wednesday, in the form of isolated showers that continued into Thursday and early Friday. Cumulative storm totals were mostly under a tenth of an inch in places where measurable rain fell, while many locations received drizzle but did not measure at all. The storm left a dusting of snow on the mountains down to approximately 5,000 feet above sea level.

San Diego's City Heights station recorded the highest total in the WeatherCurrents network with 0.07 inches. Anza placed second with 0.04 inches, with several other communities receiving 0.01 inch. A notable total of 0.13 inches was reported in East Highland by Peter Michas, as well as 0.07 inches in Yucaipa (courtesy of Don Kramer) and 0.03 inches in Temecula Valley's Wine Country (courtesy of Jim Sappington).

Sunny, yet still seasonably cool weather is predicted going into the weekend, until the possible arrival of more wet weather next week. Timing and intensity remain uncertain.

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