(CBS/AP) - California Department of Transportation traffic cameras showed snow on the ground in the Sierra Nevada on Tuesday morning.
The National Weather Service has issued a winter storm warning for the central and southern Sierra, where some areas could see as much as a foot of snow. A winter weather advisory was in effect farther north.
The cold system from the Gulf of Alaska is also expected to drop snow at much lower elevations before moving out by Wednesday.
The first organized rain showers will creep into the Yuba City area at around 8 a.m. The weather will begin to be more active by 10 to 11 a.m.
Rain showers and thunderstorms are moving into the valley today, keeping conditions gusty and chilly. Rain totals will range from .25 to .50 inches, with small hail possible in any thunderstorms that form. Winds will be out of the southeast at 10-20 mph, gusting up to 30 mph. High temperatures will be much cooler, topping out at about 51 degrees in Sacramento.
We will see low snow in places like Placerville, Grass Valley and Nevada City. Elevations around 2,000 feet can expect 2 to 4 inches of accumulation, with 4 to 8 inches possible around 3,000 feet, and more than a foot expected above 7,000 feet.
Most of the wet weather will taper off late tonight, but gusty winds will continue on Wednesday, with cool high temperatures in the 50s.
