The Heat Advisory is still in effect across Northern California and we're getting even hotter for today and Friday. A cooling trend and stronger winds will return for your weekend.

Posted: Jun 25, 2020 6:29 AM

The heat continues and even ramps up over Northern California today and Friday. High pressure in the Eastern Pacific will continue to dominate our forecast and will have more influence today than what we had over the last few days. A Heat Advisory is in effect for the valley and foothills through 8pm on Saturday, while Trinity County will have a Heat Advisory in place from noon today through 10pm Friday night, and Siskiyou/Modoc Counties have a Heat Advisory set to take effect at 11am Friday through 11pm Friday night. Skies are mostly clear across Northern California this morning, and temperatures are very warm for the start of your Thursday. Valley areas are starting out in the 70's to low 80's, foothill areas are starting out in the 70's, and mountain areas are starting out in the 50's. Winds are light and out of the Northeast this morning, but will pick up to the 10 to 15mph range out of the Northwest this afternoon. Humidity will dip into the 10 to 25 percent range this afternoon. The breezy and dry conditions are a concern for fire danger today. High temperatures are projected to be even hotter than the last few days, with valley areas ending up in the 105 to 110 degree range. Foothilll and mountain areas are projected to end up in the mid 90's to low triple digits this afternoon. We will also have a slight threat of thunderstorms across portions of the Sierra again today, but the best chance is expected to our South this afternoon and evening.

The heat peaks on Friday. Valley areas will start out in the 70's to 80's, and are projected to top out in the 106 to 112 degree range on Friday afternoon. Redding is currently projected to hit 112 degrees, which is just one degree shy of the record for June 26th. Foothill areas will start out in the mid 70's on Friday morning, and mountain areas will start out in the 50's to low 60's. High temperatures in the foothills and mountains are projected to be in the high 90's to triple digits on Friday afternoon. Winds will be out of the North to around 10mph.

We'll start to see a pattern change this weekend, but temperatures will still be well above average on Saturday. Low pressure will be dropping down into the Pacific Northwest from British Columbia and that will help to start a cooling trend over our region. Most areas will see a high temperature drop of around 8 to 10 degrees compared to Friday, and we could see a few high clouds dropping into our region by the afternoon. Winds will also become stronger and are expected to be out of the West to around 25mph. Gusts could reach up to around 35mph on Saturday afternoon. The stronger winds and the dry fuels will result in elevated fire danger through your weekend. Sunday will be much cooler than Satuday, but will still very very windy. Both low and high temperatures will be several degrees cooler than Saturday. Valley areas will start out in the mid 60's, and will end up in the high 80's to low 90's on Sunday afternoon. Foothill areas will dip into the mid 60's on Sunday morning and mountain areas will mostly start out in the 50's. High temperatures are expected to top out in the mid 70's to low 80's in the foothills and mountain on Sunday afternoon. There will also be a slight chance for some light showers in the Sierra on Sunday afternoon and evening. Sustained winds will be up to 25mph out of the Northwest on Sunday and gusts could get up to around 10mph over than on Sunday afternoon. This will keep fire danger in the moderate to high range on Sunday. Winds will not be as strong but temperatures will stay similar on Monday across our entire region. A modest warming trend will then take hold through the middle of next week that will push valley high temperatures back into the mid to high 90's by Wednesday.
