The extreme heat will continue today and unfortunately there is no relief in sight. A heat advisory will go into effect at noon on Monday and remain in place through Tuesday evening. This is for West Side Valleys and Western Siskiyou County where temperatures will rise to and exceed triple digits throughout the afternoon hours.
A fire weather watch has also been issued for the Cascades, Basin & Northern California to account for the lightning threat expected on Tuesday. Even Monday afternoon and evening a pop-up storm can’t be ruled out for the East Side and Siskiyou County. This will be very isolated but any storms that do develop with have frequent lightning and very little rain. Overnight Monday into Tuesday a pop-up storm is possible as well.
By Tuesday afternoon and evening, scattered thunderstorms will develop along and east of the Cascades and over Siskiyou County. I may even have to add thunder and lightning to the Valley. Into Wednesday the threat will continue. Best bet though is looking to be Tuesday. Once again the main threats will be frequent lightning, little rain and strong winds.
The heat will be ongoing into the weekend. Drier air moves in for the second half of the week but the heat sticks around. In fact, we could be talking about triple digit highs again for Saturday.
