The heat continues and the potential for thunderstorms will restult in elevated fire danger today and Wednesday. Skies are mostly clear this morning, but clouds will move North into our mountain areas again this afternoon. Valley areas will be mostly sunny, with a slight chance for thunderstorms from Red Bluff to the North. Mostly sunny to partly cloudy skies will be ahead for higher elevations later today, and the threat of thunderstorms will be returning to the Sierra and Northern Mountains this afternoon and evening. That threat of thunderstorms has prompted a Red Flag Warning for high fire danger in areas of Lassen, Plumas, and Modoc Counties from 1pm this afternoon through 9pm tonight. Temperatures are starting out in the 60's to 70's in the valley, in the 60's in the foothills, and in the 50's in most mountain areas. Winds are out of the Northeast early this morning, but will shift to become out of the South to around 15mph this afternoon. Gusts in the valley could reach up to around 20mph, while portions of the Sierra could get gusts up to around 50mph. Humidity is starting out above 50 percent across our region, but will dip into the 25 to 40 percent range in the valley and into the 17 to 37 percent range in the Sierra. High temperatures are projected to top out in the mid 90's to around 102 degrees in the valley today, while foothill areas end up in the high 80's to low 90's, and mountain areas mostly end up in the mid 90's this afternoon.
Slightly cooler temperatures are expected on Wednesday, but the threat of thunderstorms will continue for the afternoon and evening in the same areas as Tuesday. Low temperatures will end up in the 60's to low 70's in the valley and foothills, while mountain areas mostly dip into the 50's. High temperatures are expected to top out in the 90's in the valley, in the mid to high 80's in the foothills, and in the 80's to 90's in the mountains on Wednesday afternoon. The potential for gusty winds and thunderstorms will keep fire danger elevated in portions of the Sierra on Wednesday afternoon and evening. The threat of thunderstorms is expected to move to our South and East on Thursday, and temperatures will be similar to what we had on Wednesday. Skies will be sunny to mostly sunny on Thursday afternoon. We'll stay sunny with a slight uptick in temperatures on Friday, but most areas are expected to end up around average for this time of year.
Sunny to mostly sunny skies, and hotter temperatures are expected this weekend. The threat of thunderstorms will return to the Sierra on Saturday afternoon and evening. Valley temepratures will end up back in the mid 90's to low triple digits on Saturday, and will then climb into the high 90's to triple digits on Sunday. Skies will clear back out on Sunday into Monday, and temperatures wil be slightly hotter for the start of next week. The current projections put all valley cities back in the triple digits on Monday afternoon.
