There is an upper low now moving over the Bay Area, this feature (as expected) really forced interior valley temps to nosedive. Not only was it cooler this afternoon but this morning clouds covered beaches, coastal and interior valleys. I expect a similar pattern Thursday morning.
The low will begin to kick out so Thursday will not be as cool as Wednesday but still below average for the interior.
Skies did clear out everywhere except a few beaches, and again I expect similar performance Thursday with even better clearing Friday (thanks in part to some higher wind flow). Friday should have 15-25mph NW winds.
I expect interior temps Thursday to reach the high 70s to low 80s with more low 70s in the coastal valleys
and high 60s at the beaches.
While some breezy conditions are likely Friday and Saturday, winds should slow down on Sunday and Monday and coastal low clouds could be a bit more stubborn then.
Late next week interior temps look to be above average.
