TRUCKEE, Calif. — A white Thanksgiving appears to be in store for the greater Tahoe-Truckee region, according to the National Weather Service.

A winter storm warning will be in effect from noon Tuesday through 4 a.m. Wednesday as a cold front moves into the region late Monday.

Originally, NWS had forecast a winter storm watch for Tuesday, but forecasters upgraded it around midday Monday to a warning,

A foot or more of snow is possible above 7,000 feet, according to NWS, with 4 to 8 inches possible at lake and ground level.

“A strong cold front will sweep south during the day Tuesday and usher in much colder air, along with periods of snow into Wednesday,” according to NWS. “Snow levels may fall as low as 2,000 feet, leading to a significantly lower commute time for those traveling down the western Sierra slopes and across much (of) Western Nevada.”

Wind gusts of 45 mph are possible at lower elevations, according to the winter storm warning, with 100 mph gusts forecast across Sierra ridge tops.

As is the case with most Sierra storms, conditions will make driving a challenge. Snow tire or chain restrictions may be in effect along most highways and passes, including Interstate 80, U.S. Highway 50, California highways 28, 89 and 267, and Nevada highways 28, 207 and 431.

Heading into the weekend, NWS reports that snow is possible, although it’s too early to predict snow levels.

Low temperatures are forecast in the single digits in Truckee overnight Wednesday through Friday, with a Thanksgiving night low of 5 degrees.
