You'll probably want to take advantage of the mild heat on the way in your Tuesday forecast, as dangerous heat is on the way for the rest of this week. The low pressure parked off the coast in the Pacific that brought the modest cooling trend and active weather to our region yesterday is now tracking through the Pacific Northwest. This will continue to keep our high temperatures in check for today, but high pressure building west from the four corners region will bring a substantial rise in temperatures to our forecast from Wednesday through this weekend. We have clear conditions overhead for the start of your Tuesday, and we'll be sunny to mostly sunny today. Temperatures are starting out in the 50's to 60's in the valley, 40's to 50's in the foothills, and 30's to 40's in our mountain zones for the start of your Tuesday morning. We'll have plenty of sunshine across our region today, as the clouds and potential for showers are now off to our north in Oregon and Washington. Wind will start out of the south to 10mph, but will shift to become out of the northwest to 10mph in the valley this afternoon. Humidity will dip into the 9 to 22 percent range this afternoon, which is down compared to Monday. High temperatures will range from the upper 80's to lower 90's in the valley, while our foothill and mountain areas range from the lower 70's to lower 80's this afternoon. The lower humidity will mean fires could start easier than yesterday, but the lighter winds are keeping our fire danger in the moderate range today.

High pressure off to our east will continue to build west across our region for the remainder of this week, and will result in much hotter temperatures on the way. High temperatures will end up 10 to 15 degrees hotter in most of our region on Wednesday afternoon. High temperatures in the valley will end up in the triple digits, while foothill and mountain areas top out in the 80's to mid 90's. An Excessive Heat Warning is now set to go into effect from 11am Thursday through 9pm Saturday for the valley and foothills, and an Excessive Heat Watch has been issued for Trinity County from Thursday afternoon through Friday evening. Dangerous heat is expected from Thursday through at least Saturday. High temperatures will end up in the 104 to 113 degree range in the valley late this week into the weekend, while foothill and mountain areas have high temperatures in the 90's to lower triple digits during that time. Overnight low temperatures will also stay very warm across our region. Valley areas will mostly have low temperatures in the 70's late this week through the weekend, while foothill areas dip in the 60's to 70's, and mountain areas bottom out in the 50's to 60's.

Temperatures will start to fall on Sunday, but will still be very hot across our region. We'll finally fall back out of the triple digits by Tuesday of next week, but we'll also be staying dry. The good news is we do not have any signifigant wind events expected in your forecast, so that should help to mitigat fire danger. This is going to be a dangerous heat event, and you'll want to make sure to take precautions. Dress for the heat, make sure you're staying hydrated, and keep a close eye on the very young, the elderly, and your pets.

Dry conditions, warmer temperatures, and gusty north winds will drive high fire danger and a Red Flag Warning across most of northern California Monday. Winds will diminish and temperatures will warm up on Tuesday. We'll stay dry and heat up later this week. Cooler temperatures then return for your weekend.
