Be prepared for another day of hot temperatures, high fire danger, and impacted air quality across northern California in your Monday forecast. High pressure centered to our southeast will keep us hot and dry today, and an area of low pressure dropping south into the Pacific Northwest will start to drive breezy to gusty southwest winds along the foothills, Sierra, and southern Cascades today. A Red Flag Warning for high fire danger has been issued for portions of the foothills, northern Sierra, Shasta County Mountains, and southern Cascades from 11am Monday through 11pm Tuesday. Southwest winds to 20mph, and gusts to 35mph will be possible in our foothill and mountain areas today. We'll also have humidity values dipping into the 8 to 20 percent range this afternoon. The dry and windy conditions are a recipe for high fire danger, and the warning area does include the entirity of the Dixie Fire. Skies are mostly clear of clouds to start your Monday, but smoke and hazy will still be overhead today. Temperatures are starting out in the 60's to 70's in the valley and foothills, while mountain areas have dipped into the 40's to 50's overnight. Valley winds will mostly end up out of the south to 10mph after starting out light and out of the northeast early Monday. High temperatures are projected to top out in the upper 90's to lower triple digits in the valley, and in the 80's to mid 90's in our foothill and mountain areas. Air quality will continue to be impacted today, but we are expecting some modest improvement as the south winds pick up through the day. Most of the bigger smoke impacts will get pushed to the northeast of our active fires over the next few days.
The area of low pressure dropping south into the Pacific Northwest will bring additional cooling and breezy west winds into our forecast through the middle of this week, and there does seem to be a decent drop in temperatures in your mid week forecast. Valley araeas are projected to end up in the low to mid 90's on Tuesday afternoon, and then cool into the mid 80's to lower 90's for the middle of this week. Mountain and foothill areas will have high temperatures in the 70's to lower 80's for the middle of this week. Low temperatures will also dip by several degrees over the next few days. Valley and foothill areas will have low temperatures in the 50's to 60's, while mountain areas dip into the 30's to 40's. You may want to keep a light extra layer handy for the morning hours. Temperatures will start to heat back up into the upper 80's to mid 90's in the valley towards the end of this week, and will then climb back into the mid to upper 90's in the valley by the end of this upcoming weekend. Foothill and mountain ares will have high temperatures in the 70's to 80's this weekend.
