A very welcome change of pace is ahead for your Wednesday forecast, but there is also reason for concern today. Temperatures will be much cooler this afternoon, and are expected to end up several degrees below average. Skies will stay sunny to mostly sunny in the valley and foothills, but some clouds are expected in higher elevations. There will be a chance for some light showers along the Sierra Crest early in the day, and then the potential for thunderstorm activity will return to areas from Shasta and Lassen Counties to the north this afternoon and evening. The threat of thunderstorms over dry fuels has prompted the National Weather Service out of Sacramento to issue a Red Flag Warning for high fire danger in the western portion of Siskiyou County from 2PM through 11PM today.

Skies are mostly clear in the valley, foothills, and Northern Mountains this morning, but partly cloudy skies have returned to the Sierra this morning. We are tracking the potential for some light shower activity along the Sierra Crest early today, but the threat of more acitive weather will be looming over the Northern Mountains, Shasta County mountains, and portions of Lassen and Modoc Counties this afternoon. That is where the best chance for thunderstorm activity will be later this afternoon through this evening. Temperatures are starting out in the 60's in the valley and foothills this morning and in the 40's to 50's in the mountains early today. Winds are in the 5 to 15mph range out of the east this morning and will end up in the 10 to 15mph range out of the south this afternoon. Humidity will stay higher today, and is projected to end up in the 25 to 45 percent range this afternoon. Temperatures will also be much cooler today, with valley areas topping out in the mid 80's to mid 90's. Foothilll areas are expected to top out in the high 70's to low 80's, while Sierra locations end up in the mid 80's, and the Northern Mountains top out in the 80's to low 90's this afternoon.

Temperatures will be very similar on Thursday, but could bump up by two or three degrees compared to today. We'll also have partly cloudy skies in most areas on Thursday, but the threat of showers or thunderstorms will stay very low. High pressure will be building back into our region from Friday through the weekend and that will result in a sharp rise in temperatures. Skie swill be sunny and temperatures will end up in the mid to high 90's in the valley on Friday. Foothill and Sierra areas will top out in the mid to high 80's on Friday, and the Northern Mountains will climb back into the 80's to mid 90's.

Skies will be sunny and temperatures will be even hotter than Friday this weekend. Valley areas will end up in the high 90's to around 107 degrees, with the hottest temperatures expected on Sunday. The mid valley will end up in the high 90's to low triple digits, while the north valley ends up several degrees above the century mark. The foothills and Sierra are expected to end up in the low to mid 90's, while the Northern Mountains end up in the 90's to low triple digits. Temperatures are not expected to change much on Sunday, but will drop by a few degrees on Tuesday. Models are split on what to expect for the middle of next week. The more likely solution currently looks to be average temperatures and dry conditions, but there are models hinting at another dip in temperatures and the potential for thunderstorms returning. We'll be tracking the latest conditions and will have a much better idea of what to expect over the next few days.

As expected, we had much quieter weather around northern California on Wednesday with plenty of sunshine, much weaker wind, and a wide range of temperatures. Thursday will be similar, but much more active weather is coming.
