Today has been a hot day but active as well with many thunderstroms in the mountains. Tomorrow most will see sunny skies with highs-in the upper-90s to triple-digits. If you are in the mountains, 90s will be possible but thunderstorms will also be a concern. Lightning strikes on dry vegetation can easily spark fires. Gusty winds from thunderstorms can spread both new and existing fires rapidly.
Thunderstorm chances in the mountians have also led to a RED FLAG WARNING being issued for Modoc, Plumas, Lassen & Siskiyou counties. The thunderstorms are expected to be more numerous compared to Sunday. And compared to today, tomorrow will actually see a chance for a few of those thunderstorms to make their way into the valley.
The strong heat continues in the area through Tuesday.
By Wednesday, a broad trough of low pressure moves in the area. It does not have much moisture associated with it so the valley and mountains will stay sunny. However, it will bering temperatures back to seasonal levels. Mid-90s in the central valley and upper-90s to near 100 in the north valley.
We keep the seasonal temperatures until Saturday where temperatures begin to heat more extremely again.
