Snow and rain forecast: When to expect Sierra chain controls

March 2026 is about to go down as Northern California's warmest March on record. The return of rain and snow on the final day of the month could prevent it from also being the driest. Scattered showers will begin popping up in the Valley, Foothills and Sierra on Tuesday morning. Wet weather is in the forecast through early Thursday morning. The snow level will drop enough for accumulation at the Tahoe area summits. Wednesday is a KCRA 3 weather Impact Day specifically for the Sierra because snow and wind will affect travel in the mountains. Here is what the KCRA 3 weather team is expecting during the next few days. KCRA 3 is your home for California breaking news and weather.
