At the coast the low clouds are returning and they will drive into the coastal valleys into Friday morning. That and general onshore flow and more pace to the winds will also transport some of that cool air into the interior as well where temps have been running 15-17 degrees above average the last several days. Friday and Saturday hold hope of temps being a few degrees below average before the heat returns inland early next week.
The larger feature at play here is the upper level trough coming in, pushing an old ridge off to the east. This is a highly amplified trough so it'll sweep through quickly to be replaced by a flat ridge. These features this time of year usually promote warm inland temps but breezy conditions near the coast, and that's the outlook for the first part of next week.
As for the weekend, winds will be strong out of the NW in the afternoons. This will clear skies but also keep temps mild. Sunday into Monday that warming mentioned before starts.
