Another interesting and challenging forecast, the ridge of high pressure that fueled above average temps for a week is finally beginning to break down. That will bring inland temperatures back to near average by the end of the weekend. Coastal valleys and beaches will also see temps come back.
Of course there are a lot of other factors, smoke haze will complicate forecasts. Interior valleys have seen a lot more smoke than some coastal locations. Saturday looks like another smokey day inland with some improvement Sunday.
Early next week the remnants of former Hurricane Genevieve will move northward toward the Central Coast which will crank up humidity. Saturday into Tuesday we'll have to watch for isolated thunderstorm, especially over the mountains of San Luis Obispo and Santa Barbara counties.
Thunderstorms can produce lightning (which have started a number of fires).
