Severe heat prompts a Heat Advisory across Northern California today

Triple digit heat and the potential for mountain thunderstorms are ahead for your Monday

Posted: Jul 16, 2018 6:35 AM

Get ready for a scorching hot day across the majority of Northern California and the potential for thunderstorms in the Northern Mountains this afternoon. The thunderstorms from last night have tapered off this morning, but the potential for active weather looks likely in areas of Trinity, Shasta, and Siskiyou Counties this afternoon. Skies are mostly clear this morning, and most of our region will have sunny skies today. Clouds will increase in the mountains this afternoon. Temperatures have dipped into the 60's to 70's in the valley overnight, and into the 40's to 50's in the mountains this morning. Winds are out of the Northeast to around 5mph this morning, but are projected to become out of the South to 10mph this afternoon. High temperatures are projected to climb into the 102 to 109 degree range in the valley this afternoon, and into the high 80's to high 90's in the mountains. Humidity will dip to around 15 percent later today. The low humidity and severe heat will combine to result in high to extreme fire danger this afternoon. The potential for dry lightning in the Northern Mountains will also elevate fire danger later today. A Heat Advisory is in place for the entire valley, and some mountain areas through 8pm Wednesday night.

The severe heat will continue for the next few days, but the chance for active weather will move off to the North and East for the middle of the week. Temperatures will be as hot if not hotter than today through Wednesday. Very low humidity paired with the severe heat will result in elevated fire danger this week. There will be a very modest dip in temperatures on the way towards the end of the week, but all of Northern California will have temperatures staying above average. The potential for mountain thunderstorms will be returning later this week, and mostly looks to impact portions of the Sierra. Temperatures will continue to be very hot through your upcoming weekend.
