Rain and up to a foot of new snow expected in Lake Tahoe Basin

A new winter storm along with an atmospheric river will impact the Sierra and western Nevada starting Friday and through the weekend.

The National Weather Service is anticipating travel impacts due to rain, snow, and gusty winds for the entire weekend. Precipitation will begin in northeast California and the Sierra early Friday with very high snow levels and accumulating snow mainly above 8000 feet. Snow levels will begin to drop late Friday into early Saturday allowing accumulations down to near 4500 to 5000 feet.

The southern Sierra in Mono county will be about six hours, but snow accumulations will be similar or greater once precipitation starts because of the high elevations in that area. A colder system is expected for Sunday and Monday with the potential for additional snow in the Sierra and snow across western Nevada as well, but uncertainty remains high with the details for now.
