High pressure has build back into Northern California and that has resulted in dry, windy, and slightly warmer conditions across our region on Monday. We had some thin clouds brushing through our region this morning, but skies are mostly sunny this afternoon. Temperatures ended up warmer than this last weekend, but are still below average. Valley areas topped out in the 70's to low 80's, foothill areas ended up in the high 60's to low 70's, and mountain areas mostly ended up in the 60's to low 70's. Winds have been out of the North to around 15mph, but are expected to become lighter tonight.
The ridge of high pressure overhead will continue to be the dominant feature in our forecast through Thursday, and will result in dry and warming conditions across our region. We'll have sunny to mostly sunny skies on Tuesday and temperattures will end up around 10 degrees warmer than Monday. Valley areas are expected to dip into the mid 50's overnight and will end up in the high 80's to low 90's on Tuesday afternoon. Foothill areas can expect low temperatures in the 50's and high temperatures in the low 80's, while mountain areas will start out in the 30's to low 40's and end up in the 70's to low 80's on Tuesday. Winds will be out of the Northwest in the morning, but will shift to become out of the South late in the afternoon.
Skies will stay sunny to mostly sunny on Wednesday, but we will have some clouds moving into our region late in the day on Thursday. Temperatures will end up in the low to mid 90's in the valley on Wednesday and Thursday, foothill areas will end up in the mid 80's, and mountain areas will end up in the low to mid 80's during that time.
Low pressure tracking towards the Pacific Northwest from the Pacific will bring cooler temperatures and the potential for showers and thunderstorms back into our forecast on Friday. The best chance for active weather is expected to stay in higher elevations and the far northern end of the valley. There currently looks to be a moderate chance for thunderstorm activity in the foothills and far north valley on Friday afternoon. Gusty South winds will also be possible. Temperatures in the valley will end up in the high 70's to low 80's on Friday, while foothill areas top out in the low to mid 70's, and mountain areas end up in the 60's to 70's. There will still be a chance for showers on Saturday, but that is mostly expected to be in higher elevations closest to the Oregon border. Temperatures will be similar to Friday on Saturday.
Sunny skies and warmer temperatures are projected to return to Northern California on Sunday, and we'll be getting even warmer for the start of next week. Valley areas are currently projected to end up back in the high 80's with sunny to mostly sunny skies on Sunday, and in the mid 90's with sunny skies on Monday.
