Northern California is currently sandwiched between high pressure centered in the Desert Southwest, and high pressure off the Coast in the Pacific. This will result in hotter temperatures and gusty north winds across northern California today. The bad news is that temperatures will be much hotter and winds will continue to be gusty today, but the good news is that this will help to limit impacts to air quality in our region through tonight. Gusty north winds have kept temperatures much warmer in some areas overnight. The most obvious area where this has been the case is in Redding, where the current temperature just before 5AM is 87 degrees. Most of the valley and the foothills are starting out in the 60's to 70's this morning, while mountain areas are in the 50's to 60's. North to northeast winds to 15mph, and gusts up to 35mph are being reported early today, but winds will be shifting to become out of the east in the Sierra and foothillls this afternoon. Winds will stay gusty into the afternoon, and that is a big concern for fire danger today. Humidity will also end up very low with values expected to drop into the single digits to around 27 percent this afternoon. High temperatures will be much hotter than the last few days, and are projected to end up in the 100 to 110 degree range in the valley this afternoon. Foothill and Sierra locations are projected to end up in the upper 80's to mid 90's, while the Northern Mountains top out in the upper 80's to around 100 degrees this afternoon. Fire danger will be in the high range today.
High pressure will continue to dominate our forecast for the remainder of the week, but winds shifting to the south will help to keep temperatures several degrees cooler than Tuesday on Wednesday through Friday. Valley areas are projected to end up in the mid 90's to lower triple digits during that time, while foothill and mountain areas top out in the mid 80's to mid 90's. Smoke will have more of an impact on our air quality as the south winds return, so enjoy the improved air quality while it lasts on Tuesday. High pressure will build over our region this weekend and we'll see a return of north or east winds in our forecast area. This will result in much hotter temperatures on the way for your Labor Day Weekend, with many areas seeing potential for record setting high temperatures. Current projections are putting the valley in the 105 to 112 degree range on Sunday and Monday. Mountain and foothill areas can expect high temperatures in the mid 90's to triple digits starting on Saturday and lasting through the start of next week. Get ready for poor air quality and very hot temperatures for your first weekend of September and your Labor Day Weekend.
