Mountain freeways north of Los Angeles and the cities of Lancaster and Palmdale will see snow accumulate Tuesday night and Wednesday, as a cold storm out of Canada blows in.
Because the flow is blowing in from the north, over land, it will not pack much rain for Southern California’s urban areas, the National Weather Service said Sunday.
About a quarter inch is the most Los Angeles can expect, before the storm blows out Wednesday afternoon, and the clouds should blow out by the Rose Parade starting time on Thursday morning.
As clouds and cold air blows in Tuesday evening, the snow level in northern Los Angeles County will fall to 2,000 feet above sea level. That will coat the hills above Castaic and could cause problems on Interstate 5’s 4,140- foot Tejon Pass near Lebec, and on the Antelope Valley (14) Freeway at Acton, 2,700 feet above sea level.
The National Weather Service said today it expects about 2-4 inches of snow to accumulate on the floor of the Antelope Valley cities of Lancaster and Palmdale late Tuesday and Wednesday.
Given the expected winds from the north, the heaviest snow accumulations will be on the northern slopes of the San Gabriel Mountains, with upper elevations such as Wrightwood and Big Pine expected to get a foot of snow.
Snowfall up north, and rain in the L.A. Basin, should blow out New Year’s Eve, but the first day of 2015 will be clear and cold, the NWS said.
