The current warm-up peaks today and Wednesday when much of the Central Valley will see highs around the century mark. A gradual cooldown is forecast after mid-week as the next upstream trough approaches bringing a return of onshore flow along with synoptic cooling.

Upper troughing remains over Interior NorCal Saturday through Tuesday as associated upper low moves through PacNW into the Great Basin. Dry weather expected through the extended forecast period except for a slight chance of showers over the Eastern Shasta and Plumas county mountains Saturday afternoon into evening. High temperatures will be near to above normal through the weekend into early next week.
