Severe weather has returned to Northern California this afternoon. A Winter Storm Warning is in effect for portions of the Sierra above 5500' and is set to stay in effect through 1pm Sunday. Heavy snowfall is expected from tonight through early Sunday down to 5500', and that could result in major travel impacts. We also have a Flash Flood Watch going in effect at 7pm tonight and lasting through 6pm Saturday for the Camp, Carr, Delta, Hirz, and Mendocino Complex fire burn scars in Butte, Shasta, and Lake Counties. Rain in excess of a half an inch per hour will be possible during that time, and debris flows will be possible. The potential for thunderstorms will also bring an added threat of heavy rainfall and hail on Sunday.
Some breaks in the rain will be possible in the valley overnight and early tomorrow, but it could intensify again tomorrow afternoon. Thunderstorms will be possible in the valley again on Sunday. High temperatures are not expected to change much through your weekend, but low temperatures will stay a little bit warmer overnight.
Showers will mostly taper off by Sunday evening, and we'll be dry for the start of next week. Temperatures will become slightly warmer and skies will become mostly sunny on Monday. We'll have partly to mostly cloudy skies and mostly mild conditions on the way for the middle of next week. There will be a slight chance for some showers at times but these won't add up to much. A slightly stronger storm is lining up for the end of the week.
