Warm and mild weather for your Sunday, but big changes are just around the corner. We had sunny skies and above average temperatures across Northern California once again on Sunday afternoon. Valley areas topped out in the mid to high 60's this afternoon with some near 70 and most mountain areas ended up in the mid to high 50's. Clear skies and light winds will allow temperatures to become chilly again tonight. Overnight low temperatures are projected to dip into the mid 30's to low 40's in the valley, and mountain areas will dip into the high teens to low 30's for the start of your Monday.
Monday will be a transition day to cooler weather with clouds increasing during the day. It will be windy at times as well.
A big pattern change is on the way Tuesday through Friday. Temperatures will drop to below average and wet weather will be finally arrive after a very dry Fall. Valley rain and mountain snow look very likely on Tuesday. Snow levels will be very low as a very cold airmass moves into our region from the North. Snow could fall to as low as 2000', and some isolated areas could get a dusting of snow lower than that. Higher elevations are projected to get up to around 3 feet of snow from Tuesday through Friday. A few inches of snow will be likely in the foothills. And it may even snow in and around Redding. Mountain travel impacts look very likely, so you'll need to be cautious while making your travel plans. Valley rain is expected to be widespread and substantial. Between a half an inch to an inch of rain is in your forecast for next week, with most of that falling on Tuesday, Tuesday night and into Wednesday morning. Temperatures will dip to near or below 50 in the valley on Tuesday and mountain areas will only top out in the 30's. Temperatures will continue to cool for your Wednesday and the rest of the week. High temperatures in the valley are expected to top out in the high 40's to near 50 during that time, and mountain areas will end up in the 20's to 30's. Overnight low temperatrues will be below average for the middle of next week, with the potential for low temperatures in the 20's to 30's in the valley, and teens to 20's in the mountains.
