A winter weather advisory has been issued for heavy snowfall in the Sierra Nevada mountains, beginning Monday night through Tuesday, said the National Weather Service.
Rain is forecast in the valley Monday and Tuesday, as a cold system moves in from the Gulf of Alaska.
Another storm may bring more rain to the Sacramento area later in the week, said Craig Shoemaker, a meteorologist with the NWS.
Snow levels could drop as low as 1,500 feet elevation in the mountains along Interstate 80 and U.S. Highway 50, making travel hazardous at times on Monday and Tuesday, he said. The weather advisory is currently in place for elevations above 2,000 feet. The storm is expected to dump its heaviest amounts of snowfall Tuesday.
The higher elevations, 3,000 feet and above, will receive a possible 6 to 10 inches of new snow, while the foothills above 2,000 feet elevation will get anywhere from 2 to 4 inches.
Scattered valley showers and possible thunderstorms are expected, mainly on Tuesday, Shoemaker said. Forecasts said the valley could get up to 0.60 inches of rain in some areas.
