Temperatures are on the rise, and the threat of thunderstorms will return to some mountain areas in your Friday forecast. Skies are mostly clear and we're starting out a bit warmer than 24 hours ago in the valley. Valley areas will start out in the 60's to low 70's this morning, while foothill areas are in the 60's, and mountain areas are in the 40's to 50's. Winds are out of the Northeast to around 8mph early today, but will shift to become out of variable directions for your afternoon. Most of us will have south winds to around 10mph, but our northern zones will have north winds to around 10mph. Gusts up to around 20mph will be possible out of the north in our northern areas this afternoon, and when combined with lower humidity, that will increase fire danger compared to yesterday. Humidity is projected to dip into the 15 to 30 percent range this afternoon. High temperatures will also end up warmer than yesterday, with valley areas ending up in the mid 90's to around 100 degrees. The foothills and Sierra will mostly end up in the mid 80's to around 90 degrees this afternoon, and the Northern Mountains will top out in the mid 80's to mid 90's. Fire danger is expected to end up in the moderate to high range later today. The threat of thunderstorms will return to the Sierra this evening, and the most likely areas for thunderstorm activity in our region will be in Lassen and Plumas Counties. There will also be a slight threat of thunderstorms in eastern Shasta County this afternoon and evening. Lightning sparked fires will be a concern today.

High pressure will continue to build through northern California this weekend and that will result in well above average temperatures, sunny skies, and very dry conditions. Low temperatures will dip into the 60's to 70's in the valley and foothills through the weekend, and mountain areas can mostly expect overnight lows in the high 40's to lower 50's. High temperatures in the valley will end up in the high 90's to around 105 degrees on Saturday, and will end up a couple of degrees hotter than that on Sunday. Foothill and Sierra location will top out in the low to mid 90's this weekend, while the Northern Mountains end up in the 90's to lower triple digits.

The heat will persist through your Monday forecast, and temperatures will be very close to what's projected for Sunday. A modest cooling trend will then return as we head into the middle of next week, and that should knock all valley areas back into the double digits. Current projections put valley high temperatures in the mid to high 90's by Wednesday and Thursday. Foothill and mountain areas will top out in the 80's to low 90's for the middle of next week. Models are currently split on whether or not we can expect the potential for active weather to return to higher elevations in your extended forecast, so we will continue to monitor the threat of more thunderstorms closely over the next several days.

It was a bright and breezy Friday for northern California, however the wind has been much stronger over Modoc County where a High Wind Warning is in effect through this evening. Stronger wind and cooler air will define our weather Saturday.
