A cold low-pressure system out of the Gulf of Alaska will generate isolated showers in Southern California Wednesday and Thursday, while bringing snow to the mountain communities.
The chance of measurable precipitation in the Los Angeles area has been set at a low 20 percent.
In the mountains, the snow level was expected at 4,500 feet Wednesday, then lower to 2,500-3,000 feet Wednesday night and Thursday, according to the National Weather Service.
Forecasters expect 2-4 inches above 6,000 feet but 1-2 inches across The Grapevine and the Interstate-5 corridor and a dusting across the Antelope Valley foothills, including Highway 138 -- Pearblossom Highway on Thursday.
Wind gusts of 45 miles per hour are expected Wednesday, diminishing to 40mph on Thursday. The storm will cause travel delays and road closures, strong crosswinds, low visibility in blowing snow, and icy roads, the National Weather Service said.
