Update from meteorologist Dave Hovde at 8:57am

From meteorologist Dave Hovde: Afternoon thunderstorms are likely in the hills and mountains and steering winds could carry them toward inland communities…so we have a flash flood watch in place….
There is a chance of thunderstorms in the mountains and some interior areas during the afternoon and evening hours through Tuesday. Over the last few days some flash flooding has happened in interior areas of both Santa Barbara and SLO counties, the difference today is that steering current could take storms that form further west and could potentially impact larger communities. Rain rates over 1″ per hour are possible. A watch means this activity can happen a warning is when it is happening. We are currently only in a watch.

Are more thunderstorms possible Saturday? Yes. This is the Storm Prediction Center outlook for Saturday.
Overnight and morning coastal low clouds will persist in coastal and valley areas into next week. Cooling is expected through the weekend, then some warming is expected next week.
Thunderstorms are developing faster than yesterday and covering more of the area but limited steering winds aloft will keep them near their formation area. As of 4pm most of the activity has been in the Temblor Range in between SLO and Kern county.

KSBY weather app Doppler is showing those mountain thunderstorms and indicating lightning as well. The app also shows future radar, watches and warnings and more.
These are driven by cold air aloft and daytime heating of the land mass. Since the mountains extend several thousand feet up into that cooler air, that is why storms form there and not at the coast where temps are cooler and atmosphere stable. This condition will be around into early next week. Sunday and Monday we’ll have to watch this carefully as steering winds from the NE could carry storms that form back toward Central Coast communities, but the chances are under 30%.
Elsewhere, the marine layer is expected to deepen as the upper low moves overhead this weekend, likely pushing into all the valleys by sunrise.
Winds out of the South will shift to the West on Saturday which is a slow clear for the SB Southcoast.
Inland temps will warm next week into the lower 90s but near the coast the typical night and morning clouds with clearing pattern will keep temps there in check.

Here is the #PasoRobles daily forecast from the app. Check out the return of 90s next week.
Late next week interior temps could dip a bit.
