NOAA has issued a Winter Storm Warning for the west side of Lake Tahoe that is calling for 6-16″ of snow tonight through Tuesday.

“A spring storm will drive a cold front through the region with rain changing to snow as snow levels lower to near 7,000 feet by Monday morning.

Plan on slushy Sierra passes by Monday morning with 1 to 4 inches of wet snow possible between 7000 and 8000 feet with 4 to 8 inches possible above 8000 feet. Monday will also be the best potential for spillover rainfall across western Nevada valleys as the front moves through. Rainfall totals will generally be 0.25-0.75 inches in the valleys.

As colder air filters in behind the front, snow levels will continue to fall below 6,000 feet by Tuesday morning. Scattered snow showers are possible through the day Tuesday with isolated thunder and pellet showers possible. Some light snow will fall down to Lake Tahoe level and for much of Mono County, but ground temperatures may make road accumulations difficult. Some grassy surface may lightly accumulate.”

Last year, Lake Tahoe saw non-stop snow for 9 days in the end of May and it was absolute fire.
