Synopsis
Increased onshore flow will result in more widespread night/morning clouds and coastal drizzle. Cooler temperatures are also expected, especially closer to the coast. Seasonable weather conditions are then anticipated Friday and into the upcoming weekend.

as of 02:00pm PDT Wednesday...Coastal stratus persists right along the coast or a little offshore from the Bay Area and Central CA coastline this afternoon. The marine layer continues to vary between 1500 and 2000 ft deep which, coupled with onshore flow, has allowed for more cooling inland. Several sites are reporting about 1-6 degrees cooler than 24 hours ago.

Looking at the synoptic pattern, an upper level trough is still on track to move into NorCal tonight into Thursday. That will help support our continued marine layer and the cooler temperatures. It's also likely that the marine stratus along the coast could be thick enough to produce drizzle and we may even see a few observations of measurable precipitation from that drizzle. Even the hi-res NAM has been showing hints of light precipitation for some of our coastal locations. Don't be surprised if you need to use your windshield wipers tomorrow morning.

As this trough moves into CA, this will enhance onshore flow so we expect breezy to windy conditions along the coast. Speaking of winds, many people have called our office concerned about smoke from the larger wildfires in far NorCal. The smoke is being pushed north and eastward from the southwesterly flow as that trough moves inland. Thus, the Bay Area and Central CA coast won't have any smoke concerns.

The trough will continue to track eastward Thursday night into Friday which will allow for a minor warm up on Friday and Saturday. Highest temperatures will be in the interior portions of our CWA where max temps will range in the upper 80s to upper 90s. Closer to the coast and Bay area will see upper 60s to mid 80s.

In the extended forecast, there's the potential for another trough to track well north of our CWA. This will likely nudge our temperatures back down to seasonable values.
