Get ready for dangerous heat on the way in your Thursday forecast. High pressure off to our east will continue to build into northern California today, and we also have high pressure off the coast in the Pacific. This will result in very hot and dry conditions across our region over the next few days. An Excessive Heat Warning is in effect for the valley, foothills, and a portion of Plumas County through 9pm Saturday evening. Temperatures up to 113 degrees will be possible in the valley through that time, and we'll have 90's to triple digits in store for our foothill and mountain areas. A Heat Advisory will go into effect in Trinity County at 11am this morning, and is set to last through 11pm Saturday night. High temperatures in the 90's to triple digits will be possible there over the next few afternoons. We'll also have gusty north winds and very low humidity helping to drive high fire danger today. Some thin clouds have tracking north into northern California over the last 24 hours, but those clouds will continue to thin out through the day. Mostly sunny conditions are expected over most of our region. Temperatures are starting out in the 60's to 70's in the valley and foothills this morning, and we're starting out in the 40's to 50's in our mountain zones. Wind up to 15mph out of the north looks likely for the valley today, with gusts up to around 25mph. Humidity will dip into the 2 to 13 percent range across most of our region this afternoon. High temperatures are projected to end up in the 107 to 112 degree range in the valley, while foothill and mountain areas end up in the 90's to triple digits this afternoon. Record breaking high temperatures are in the forecast for several cities across our region. Our fire danger will also be high due to the hot, dry, and windy conditions across our region, so it's extremely important to be cautious today.
Projected record breaking heat today:
Redding: 110/108 (1985)
Red Bluff: 111/109 (1985)
Willows: 111/106 (1906)
Paradise: 103/102 (1985)
Temperatures will be just as hot if not a degree or two hotter across our region on Friday. We'll have sunny skies, but will have a shift in the wind. South wind in the 10 to 15mph range will be likely on Friday. That will help to decrease fire danger slightly, but the hot and dry conditions will keep our fire danger in the high range. Record high temperatures are a little harder to break for most of us on Friday, but we could still have some records broken on Friday afternoon. High pressure will stay strong across our region through this weekend, but low pressure approaching the West Coast will result in our high temperatures dropping by a couple of degrees each day this weekend. We'll still end up well above the century mark in the valley, and in the 90's to low triple digits in our mountain and foothill areas.
The low pressure approaching northern California from the Pacific will help to break down the high pressure early next week and that will help to result in temperatures dropping back into the upper 90's to lower triple digits in the valley on Monday. We'll have high temperatures in the upper 80's to lower 90's in the valley on Tuesday and Wednesday. Foothill and mountain areas will end up in the 80's to 90's on Monday, and then mostly in the upper 70's to mid 80's from Tuesday into Wednesday of next week. The good news is that there is an end in sight to the dangerous heat, but the bad news is we do not have any decent chances for wet weather through our region in your extended forecast.
