The heat persists across Northern California today, and the potential for thunderstorm activity will linger in the far northern portions of our region this afternoon and evening. High pressure off to our east will be the dominant feature in your forecast today, but low pressure passing through to our southeast will continue to kick up the potential for active weather in areas to the north of Redding. Temperatures are starting out in the 60's to 70's in the valley and foothills this morning, and mountain areas have dipped into the 40's to 50's overnight. Winds are light and out of the northeast early today, but will shift to become out of the south to 10mph this afternoon. Gusts up to around 20mph will be possible in the valley later this afternoon and this evening. Humidity is projected to dip into the 15 to 30 percent range across our entire area this afternoon, and fuels are still very dry. Fire danger is mostly expected to stay in the moderate range, but could lift into the moderate to high range in portions of Shasta, Siskiyou, Modoc, and Northern Trinity Counties if the projected thunderstorms do occur later today. High temperatures are projected to be just as hot, if not a little hotter, than yesterday. Valley areas are projected to end up in the 99 to 105 degree range this afternoon, while foothill and Sierra locations top out in the low to mid 90's, and the Northern Mountains end up in the 90's to around 100 degrees later today.
Sunny skies, less active conditions, and hot temperatures are expected over the next few days. The temperature trend is not expected to change much, but we could see a slight dip in low and high temperatures from the middle to latter part of your work week, as low pressure approaches the Pacific Northwest. This could increase the onshore flow, and leave us with some modest influence from the Delta Breeze in some areas. Valley areas are projected to dip into the 60's to low 70's over the next few days, and top out in the 90's to low triple digits. Foothilll areas will dip into the 60's to 70's and end up in the high 80's to low 90's for the rest of this work week, and mountain areas will start out in the 40's to 50's and end up in the 80's to 90's from Wednesday through Friday.
High pressure will build across Northern California from the Desert Southwest this weekend, and that is expected to result in an uptick in temperatures. Overnight low temperatures will stay in the same range as the next few days this weekend, but high temperatures will end up a couple of degrees hotter. Valley areas are expected to range from around 98 to 104 degrees on Saturday and Sunday, whlie foothill and Sierra locations end up in the low to mid 90's through your weekend. The Northern Mountains will mostly end up in the low to mid 90's this weekend, but parts of Trinity County could see high temperatures in the high 90's to around 100 degrees for both Saturday and Sunday. Skies will be sunny, and there is currently not much of a chance for thunderstorm activity returning in your extended forecast.
