Lower foothill residents beware: You may wake Thursday to find snow at your doorstep.
The National Weather Service forecasts that snow may land and stick in Auburn, Placerville, with a possible overnight dusting as low as El Dorado Hills.
Several weather systems will keep temperatures below normal in the Sacramento Valley for the next week and bring snow to the Sierra, according to weather service forecasts.
A winter weather advisory has been issued for the greater Lake Tahoe area from 10 p.m. Wednesday to 10 p.m. Thursday, when the heaviest snow is predicted to fall, the weather service reports. Total snow accumulations of between 6 to 10 inches are forecast above 7,000 feet during that time.
Caltrans is warning hill and mountain travelers to be prepared for bouts of intense winter weather, making roads slick.
"Intermittent periods of rapid snow accumulations on Donner and Echo Summit passes are expected with this storm, impacting travel on foothill and mountain highways, including Interstate 80 and U.S. Highway 50 where chain controls are expected," Caltrans said Wednesday. "Additionally, the severe cold will create very slick and icy conditions on all Northern California roadways."
