Showers are possible at times through Memorial Day weekend. Nicer weather returns next week. Additional cool troughs with unsettled weather are possible as we go into June.
We have a chance for showers Saturday into Monday morning as an active pattern returns to the Pacific NW for the weekend.
The best chance for showers over Donner Pass looks to be Saturday night into Sunday. Snow levels could fall as low as 7000 ft. Saturday night which is just below pass level, and as low as 6000 ft. by Sunday morning. With the sun down any heavier snow showers could coat the roads during this period.
Watch for possible slick roads over Donner Pass, and possibly chain controls if the moisture shifts far enough south for some heavier showers.
We could see a few scattered snow showers again Sunday night, but anything that falls Saturday into Sunday night should have a hard time sticking. But if temperatures fall below freezing Sunday night there could be a few slick spots.
We should dry out Monday through the end of next week. Additional troughs are possible in June with unsettled weather. We will keep an eye on it and will let you know.
