A cold storm sweeping down from the Gulf of Alaska into the North Coast will bring rain on and off this week, with a chance of a dusting of snow today in the higher spots of Mendocino and Lake counties.

"This is a typical winter storm," said Will Pi, a meteorologist with the National Weather Service in Monterey. "It will be colder, but not much moisture, 2 to 4 inches over the next week."

In the Sierra, the snow level will drop to 3,500 to 4,000 feet this week and 5,000 feet next weekend, Pi said.

The forecast is for 5 to 10 inches of snow today in the Sierra, with rain and snow showers the rest of the week.

There is a chance of some light accumulations of snow today in Lake and Mendocino counties, following snow showers that hit the area Saturday.

About 2? inches of snow fell Saturday in Lake County in areas above 1,800 feet between 11 a.m. and 5 p.m., said Holly Osborne, a Weather Service meteorologist in Sacramento.

Caltrans crews were working overnight Saturday into Sunday morning on Cobb to clear roads.

Snow was reported at the Cal Fire station on the Ridgewood Grade, which is at an elevation of 2,000 feet just south of Willits, but it didn't stick, said communications coordinator Steven Doyle.

"Today, we have nothing, just foggy and overcast," he said.
