Slightly above average temperatures, breezy south winds, and impacted air quality are ahead for your Monday. Low pressure tracking towards the Pacific Northwest from the Pacific will bring breezy south winds through our region today, but is not expected to bring any shower activity to our region. Temperatures are starting out in the 50's to 60's in the valley and foothills, while mountain areas have dipped into the 30's to 40's in most areas overnight. Winds are out of the northeast to around 10mph this morning, but will shift to become out of the south from 10 to 15mph this afternoon. Gusts up to around 20mph will be possible out of the south later today. Humidity is projected to dip into th e10 to 30 percent range across our entire region. High temperatures will end up in the upper 80's to low 90's in the valley, while foothill and mountain areas top out in the upper 70's to mid 80's this afternoon. The breezy winds, and low humidity will keep fire danger in the moderate range for most of us today. This is also the last full day of the summer season.
A very modest dip in temperatures is expected for your first day of the fall season on Tuesday. Valley areas are currently projected to end up in the mid to upper 80's, while mountain and foothill areas top out in the 70's to lower 80's on Tuesday afternoon. We'll stay in that same range on Wednesday, but a few more clouds will move into our region. There will be a chance for some showers along the coast as early as Wednesday night, but the latest models are keeping those at bay until Thursday afternoon and evening. The potential for showers will be as far inland as Redding, but valley showers are not likely as the trough moves into the Pacific Northwest late this week. Temperatures will be slightly cooler on Thursday afternoon in most of our region, but only by around 1 to 2 degrees compared to Wednesday.
The low pressure will move out of our region and to the east on Friday and high pressure will rebuild over our region. This will result in a modest uptick in temperatures on Friday afternoon, and a more substantial rise in temperatures through your weekend. Valley areas can expect high temperatures back in the mid to high 80's on Friday, and then in the mid to upper 90's this weekend. Mountain and foothill areas will end up back in the upper 70's to lower 80's on Friday and then in the mid 80's to lower 90's for your first weekend of the fall season. Skies will be clear, but we will likely still be dealing with haze and patchy smoke from wildfires.
