The heat continues across northern California and high fire danger is going to return this week. High pressure off the coast in the Pacific will continue to be the main driving factor in our forecast over the next couple of days, but we will also see influence from an area of low pressure dropping into the Rockies. This setup is very similar to the one from last week, and will bring dry and windy conditions back into our forecast. A Fire Weather Watch has been issued by the National Weather Service out of Sacramento for the valley and foothills from this evening through Wednesday morning due to the dry conditions and gusty north winds. The potential for gusty north winds and very dry conditions will keep fire danger high late this week, but a welcome cooling trend will return in your extended forecast.
Skies are clear and air quality is mostly in the good range for the start of your Monday. Temperatures are starting out in the 50's to 60's in the valley and foothills, while mountain areas are ranging from the high 20's to 40's this morning. Skies will stay sunny through the day, and winds will be out of the north or northeast to around 10mph. Humidity will dip into the 10 to 20 percent range in most areas this afternoon. High temperatures are projected to top out in the upper 80's to mid 90's in the valley, and in the mid 70's to mid 80's in the foothills and mountains. Fire danger will stay in the moderate to high range today, and will start to increase again tonight.
Temperatures will be similar across our region on Tuesday and winds will be picking up out of the north to northeast. Sustained winds to around 20mph will be possible on Tuesday and Wednesday, while gusts mostly top out around 30mph. Locally stronger gusts will be possible in the foothills and favorable canyons. A cooling trend will arrive in our region on Wednesday, and will ramp up later this week. Temperatures in the valley will continue to top out in the mid 80's on Wednesday , and willl then slide back into the upper 70's to low 80's on Thursday and Friday. Foothill and mountain areas will mostly end up in the 70's on Wednesday, and then dip into the 60's to lower 70's on Thursday and Friday. Gusty north to northeast winds will continue to result in elevated fire danger on Thursday and Friday.
An area of low pressure will track across the Pacific Northwest this weekend, and that will bring even cooler temperatures to our forecast. We'll also have a chance for showers in our region from Saturday through Sunday, but the models are keeping the wet weather in the mountains. Valley areas will mostly top out in the low to mid 70's this weekend, while mountain and foothill areas end up in the upper 50's to mid 60's. Make sure to stay safe with the elevated fire danger across our region this week, and get ready for a big drop in temperatures ahead for your weekend.
