One more decent day to go, then we return to a stormy weather pattern for the rest of this week.

We will have partly cloudy skies Tuesday with chilly afternoon highs in the mid to upper 30s. Our next winter storm hits the Sierra by Tuesday evening with chain controls likely by early Wednesday morning. This is a warmer storm, compared to the last one, with moisture moving up from the tropics in an “atmospheric river” event that will give us a lot of mountain snow and valley rain.

Atmospheric rivers originate around the Hawaiian islands and pull up a lot of warm moisture. This one funnels right into the Sierra by Wednesday and Thursday. We could see a few light snow showers Wednesday morning in our valleys, and then our snow levels rise dramatically, above 7,500 feet with heavy snow in the high Sierra that will make travel difficult through Thursday. Rain will be heavy at times for our valleys on Wednesday and Thursday. Look out for minor flooding of rivers and streams.

Our storm tapers off late Thursday with a slight chance for a few scattered showers through the weekend, mainly north of Reno with highs in the 40s.
