SACRAMENTO, Calif. — Northern California is in the grips of hot and potentially dangerous weather Friday before big changes by the end of the weekend.
The National Weather Service has issued an Excessive Heat Warning for Northern California Valley locations for dangerous heat potential. The warning begins at 11 a.m. and expires at 10 p.m. The temperatures are expected to rise to 102-107 degrees by the afternoon but very warm temperatures will continue into the evening. It's expected to be around 80 degrees until around 10 p.m. Friday night.
Special care should be taken to stay indoors and find air conditioning during the hottest parts of the day. Seniors, pets, and children are especially at risk as well as people unhoused or those working or recreating outdoors.
Saturday will be hot as well with high temperatures above 100 degrees.
Sunday will be a day of rapid changes. Wind will kick up during the day and after days of hot weather created a fire risk for part of Sunday. Valley temperatures will fall and many locations will only warm to the upper 80s.
Sunday afternoon and evening the Sierra and Coastal Range will see a chance of rain and thunderstorms. Rail totals are expected to be light but rain on a weekend in June always catches people off guard so pay special attention if you are doing anything outdoors or camping Sunday.
