The warning, in effect from Friday afternoon through 6 a.m. Sunday morning, reports that a cold system with lower snow levels and heavy snow will drop south over the region into the weekend.
The heaviest snow will be Friday night with a second round Saturday night, with the forecast calling for 4 to 8 inches at lower elevations, and 12 to 18 inches over the mountains. Peaks could see snow accumulations of up to 3 feet.
Areas in Lake County forecast to see some snow include Cobb, parts of the Mendocino National Forest north of Upper Lake and Mt. Konocti.
Lake County is primarily expected to see rain, which the National Weather Service forecasts to range from as little as a tenth of an inch in some areas of the southeast county to up to half an inch in the south county and about an inch in the northern part of the county.
Rain is expected through Sunday, when the forecast calls for conditions to clear.
Forecasters also are predicting wind gusts of up to 25 miles per hour in lower elevations and more than 30 miles per hour in the Cobb area on Friday night and into Saturday, with single digit wind speeds expected on Sunday.
Nighttime temperatures are expected to dip into the high 29s on Saturday before gradually rising into the low 40s early next week.
Daytime temperatures next week are forecast to rise into the low 70s, the National Weather Service said.
