Cold winter storm brings scattered showers, snow to areas of SoCal

A cold storm out of the Gulf of Alaska will generate snow in the San Gabriel Mountains Tuesday while rain is expected in urban areas, forecasters said.

"Significant travel impacts are likely across Interstate 5 near The Grapevine due to accumulating snow and icy road conditions,'' according to an NWS statement.

A winter weather advisory, which denotes challenging travel conditions, will be in effect until 10 tonight in the San Gabriel Mountains, but a winter weather advisory scheduled to be in effect in the Antelope Valley until 10 tonight was canceled shortly before 6 a.m.

The NWS said between two and six inches of snow are expected in the San Gabriels and accumulation of up to four inches is ``likely'' across Interstate 5 near The Grapevine.

"Plan on slippery road conditions. Be prepared for reduced visibilities at times,'' urged an NWS statement.

In urban areas, including metropolitan L.A., it will be mostly cloudy today with a chance of showers and a slight chance of thunderstorms, according to the NWS. Wednesday should be sunny, but rain will return to L.A. County on Thursday.

Temperatures, meanwhile, will remain on the chilly side for Southern California, with no L.A. or Orange County community expected to exceed the high 50s today.

The NWS forecast showers in L.A. County today and highs of 40 degrees on Mount Wilson; 48 in Palmdale; 49 in Lancaster; 53 in Saugus; 55 in San Gabriel; 56 in Burbank; 57 in Long Beach and Pasadena; and 58 in Downtown L.A., Avalon, Woodland Hills and at LAX. Rain is also in the forecast on Thursday, Friday and Saturday, and a slight warmup is expected Sunday.

Showers were also forecast in Orange County today, along with highs of 51 in San Clemente; 53 in Mission Viejo; 56 in Newport Beach, Laguna Beach, Irvine and Yorba Linda; and 57 in Fullerton and Anaheim. More showers are expected in Orange County Friday and Saturday. A sharp warmup is expected Monday.
