Overnight showers Monday into Tuesday morning brought a moderate round of rainfall around the region, according to National Weather Service reports for the North Bay.
While the storm's effects were minimal in this area, they were more severe in the Sierra Nevada where heavy snowfall called for vehicle controls and tire chains, the CHP reported.
Highway 80, heading west out of the Reno area, was closed for awhile Tuesday morning due to snow and traffic problems, including cars spinning out. But at times, Caltrans and the CHP were allowing some cars through, 20 at a time, the CHP reported.
The worst stretch was from the Nevada state line to three miles east of Gold Run in California.
Chains also were required on Highway 50, from four miles east of Placerville to Meyers.
"It's just a mess and it's still coming," said Tina Hopkins at the CHP office in Truckee.
Several feet of snow already have fallen in the mountains, bringing a massive start to the ski season prior to the long Thanksgiving holiday weekend.
At least another foot of snow was expected Tuesday in higher elevations around Lake Tahoe, with several inches due at lake level.
It was all blustery enough to warrant a winter storm warning in the Tahoe area, with snow showers and gusty, freezing winds due Tuesday. Temperatures looked to fall to about 12 degrees in the area Tuesday afternoon.
The mountain forecast called for dry skies after Tuesday until the weekend, when more snow could fall.
In Sonoma County early Tuesday, Sebastopol rainfall watchers reported as much as .5 and .47 inches in a few neighborhoods as of about 7 a.m.
Santa Rosa residents reported about a quarter inch or slightly more in multiple areas.
Guerneville checked in with .67 inches, Sonoma reported .26, Rohnert Park had .28 and Windsor showed .23 inches. Cloverdale had .33 inches in one spot and Geyserville received .35 inches.
In Mendocino County's Redwood Valley, one resident reported .56 inches.
The residents are trained volunteers with the weather service who report rainfall and other data at about 7 a.m. daily.
