Despite last week's spring-like weather, winter has another wallop in store for the Sacramento region, according to National Weather Service forecasters.
A cold system will bring showers to the valley and snow to the Sierra Nevada mountains Monday night through Wednesday, said Craig Shoemaker, a meteorologist with the Sacramento office of the NWS.
Another storm may follow later in the week, he said.
Monday night's storm could make for hazardous travel on Interstate 80 and Highway 50,with 1 to 6 inches of snow predicted as low as 2,500 feet.
Shoemaker said snowfall will be heaviest on Tuesday, with a total of 6 to 12 inches falling above 3,000 feet elevation.
Meanwhile, the valley will see scattered showers and possible thunderstorms, mainly on Tuesday.
"Expect 0.20 to 0.50 inches across the valley," Shoemaker said. "The focus of the precipitation will be Tuesday afternoon and evening."
