Be prepared for a chilly morning and a warmer afternoon across northern California today. High pressure is set up to our south and will keep our region dry today. Skies are mostly clear for the start of your Friday and will continue to be mostly sunny through the day. There is a slight potential for modest fog development in the Northern Mountains this morning, and frost will be possible in some areas. Frost will more than likely be the biggest issue in the mid valley where winds have been mostly calm overnight. Temperatures are ranging from the 30's to 40's in the valley and foothills this morning, and mountain areas have dipped into the teens to low 30's overnight. We'll have north winds up to 15mph in the valley and foothills, and winds out of the east to 15mph in the Sierra today. High temperatures are projected to end up in the mid 60's in the valley, in the 50's to lower 60's in the foothills, and in the 40's to 50's in the mountains this afternoon. All around, today looks mostly mild and comfortable.
The set up for Saturday looks very similar to what we'll see outside on Friday, but low temperatures may end up a few degrees cooler and high temperatures will end up a couple of degrees warmer. Skies will be sunny through the day on Saturday, and it looks like a great day to get outside. Low pressure tracking through the Pacific Northwest will bring a modest dip in temperatures and some clouds back into our forecast on Sunday. High temperatures will dip into the low 60's in the valley, mid 50's in the foothills, and upper 40's to mid 50's in the mountains. The clouds moving in will also help to keep overnight low temperatures slightly warmer on Sunday and Monday. There will be a decent chance for showers in the Northern Mountains from Sunday evening through mid day on Monday, and we'll also have a slight chance for showers in the far northern Sierra.
We'll fluctuate between mostly sunny to partly cloudy skies from Monday through the middle of next week, and our temperature trend won't change much from Sunday. There is a chance for more mountain showers on the way from Tuesday evening through Wednesday as another area of low pressure tracks through to our north. Models are even hinting at a slight chance for light showers in the far northern zones of the valley Wednesday afternoon through early Thanksgiving day on Thursday. The best chance for showers will stay in the mountains, and travelers heading north to Oregon or East to Nevada for the holiday will want to keep a close eye on the potential for wet weather from Tuesday evening through Thanksgiving day.
