Record-breaking heat has been the main weather story for most of California today, as well as massive fires and huge amounts of smoke billowing into the air. Both Redding and Red Bluff broke records today, and records could easily fall on Labor Day Monday. Tonight will be a clear night except for areas of smoke and haze. Lows will be unseasonably warm in the foothills and valley ranging from the 60s to near 80, with 50s and 60s in the mountains. Monday will be another mostly sunny to sunny day with more areas of smoke and haze, and continued dangerously hot temperatures. Highs will range from the 90s in the mountains to over 110 degrees in the hottest valley locations.
An Extreme Heat Warning remains in place for our entire area through Monday night, and in a few places through Tuesday evening. This is due to a strong ridge of high pressure in control of the weather over the western United States. A trough of low pressure will pass over the Pacific Northwest and Great Basin late Monday into Tuesday. It won't bring any chance for rain, but unfortunately it will usher in stronger wind out of the north and northeast from late Monday through early Wednesday. A Red Flag Warning is in effect during that time due to the wind, heat, and dry conditions. Thankfully, highs will decrease after Labor Day, but they will remain in the 90s and lower 100s next week.
