Warm and mild weather is on the way for your weekend forecast, but big changes are just around the corner. We had sunny skies and above average temperatures across Northern California for your Friday afternoon. Valley areas topped out in the mid to high 60's this afternoon 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 Saturday. I'd definitely have a jacket handy if you're looking to get outside early either day this weekend. High temperatures will become warmer on Saturday into Sunday. Valley areas will top out in the mid 60's to low 70's, and mountain areas will end up in the 50's to low 60's both days this weekend. Skies will be sunny and winds will mostly be light.
A modest drop in temperatures and stronger winds will be on the way in your Monday forecast. The current outlook brings sustainded wind out of the North up to around 20mph, with gusts to around 35mph. Some more wind prone areas may have stronger gusts than that on Monday. Winds are projected to lose strength on Monday night and will not be as big of a concern for the middle of the week. A big pattern change is on the way from Tuesday through Friday of next week. Temperatures will drop to below average and wet weather will be returning. 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 2500', 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. 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 the lions share of that falling on Tuesday. Temperatures will dip into the mid 50's 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 low 50's 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.
