[National Weather Service] – A cold storm system will push southward from the Gulf of Alaska across the forecast area tonight (Thursday) and continue through Friday night.
Snow levels will plummet from 4,500 feet later this evening to 2,000-3,000 feet on Friday.
Elevations above 4,000 feet can expect between 4 and 8 inches of snow, with lesser amounts at lower elevations.
Major roadways that will likely be impacted by snow showers and icy road conditions include Interstate 5 (from Castaic to the Grapevine), Highway 14 through Soledad Canyon into the Antelope Valley, Highway 33 in the Ventura County mountains, and Highway 138 in the Antelope Valley.
Non-mountainous areas that are at risk for snow showers on Friday include the Antelope Valley, Cuyama Valley and interior valleys of San Luis Obipso County. Even foothill areas could see a light dusting of snow.
Due to the convective nature of this system, there is a slight chance of thunderstorms capable of producing brief heavy downpours and small hail. Dangerous winter driving conditions can be expected in the mountains with this system, with the potential for road closures.

• Upper Big Tujunga Canyon Road from Angeles Forest Highway to SR-2 (Angeles Crest Highway)
