A cold storm system out of the Pacific Northwest will bring the Southland a slight chance of showers and thunderstorms today.
Only a 10th of an inch of rain was expected in metropolitan Los Angeles but up to a quarter of an inch is possible in the county’s eastern tier, according to the National Weather Service. The chance of measurable precipitation was set at 20 percent.
The chance of thunderstorm is greatest over coastal waters north of Point Conception, NWS forecasters said.
Gusty winds, meanwhile, will pack the power to topple trees and high- power lines. The winds over coastal waters will subside this morning but revert to gale-force strength in the afternoon, a statement said. A small craft advisory will be in force until 3 a.m. Thursday.
In the San Gabriel Mountains, the snow level was at 5,500 feet this morning, the NWS said, and between one and two inches of snow are expected to accumulate above 6,000 feet by this morning.
The storm, “the first relatively cold storm system of the season,” arrived Monday, and light rain began falling by late afternoon, just in time for the evening rush hour.
Temperatures today will remain around 10 degrees below normal but mild, with the NWS forecasting partly cloudy skies and highs of 55 on Mount Wilson; 59 in Palmdale and Lancaster; 66 in Saugus; 67 in Mission Viejo; 68 in Avalon, Pasadena, Burbank and San Clemente; 69 at LAX, in San Gabriel, Woodland Hills and Irvine; 70 in Fullerton; 71 in Long Beach, Laguna Beach, Yorba Linda, Anaheim and Newport Beach; and 72 in downtown L.A.
Wednesday’s highs will be about the same but under sunny skies.
