GOES-West visible imagery offers a similar snapshot compared to yesterday with marine stratus blanketing the Pacific Coast. The one difference to point out would be a thin shield of high clouds passing over the northern third of the Golden State. All in all, a very pleasant day on-tap for the San Francisco Bay Area and Central California Coast with minimal weather impacts to speak of. High temperatures will land in the 50s and 60s along the immediate Pacific Coast, warming to the 70s and 80s for interior locations.
The synoptic picture features a trough over Western North America with a strong ridge over the Eastern United States. The trough axis has remained quasi-stationary over the last several days, which has promoted the overall tranquil late June, and now, early July weather. The trough will weaken on Thursday as the Eastern Pacific returns to more zonal flow aloft. That said, tomorrow will be largely a repeat of today with marine stratus for the coast and mostly clear conditions inland.

Upper-level pattern will transition to zonal flow on Friday/Saturday as 500 mb heights begin to increase. This will correspond to some synoptic warming at the surface, mainly for inland locations, through Saturday. Overall, this warming will just return interior communities closer to early July climatology. In fact, HeatRisk for Independence Day will remain Low (green) along the coast and Minor (yellow) inland with the usual coastal stratus.
Ensembles advertise ridging over the Desert Southwest late weekend and early next week. Still do not foresee much in terms of HeatRisk beyond the Minor (yellow) and very isolated Moderate (Orange) categories for central and northern California through early next week. According to the National Blend of Models, the only local areas with at least 20% probability of exceeding 90 deg F through next Tuesday are confined to far eastern Contra Costa, southern San Benito, and southern Monterey Counties.

Stratus with MVFR ceilings are solidly in place along the coast this evening. Locally breezy onshore winds continue this evening before decreasing overnight. Later tonight some of CIGS may briefly drop to IFR, but this is starting to look less likely with them starting around 1500 to 2000 feet. The stratus is expected to clear again in most areas, but this may be brief at the immediate coast. Stratus, mainly MVFR ceilings with localized IFR, will redevelop tonight into Friday morning.
Vicinity of SFO, VFR through the evening. Low confidence of a brief return of MVFR ceilings Thursday morning. Winds will increase to around 15 kt again Thursday afternoon before diminishing again overnight.
SFO Bridge Approach, Similar to SFO.
Vicinity of SJC and OAK, VFR conditions through the evening. Confidence is moderate that MVFR stratus will return late tonight into Wednesday morning at OAK. So far not much has developed as of 05Z so confidence is getting lower on this. At SJC, VFR conditions are likely to prevail through Thursday morning. Some stratus is moving north near Morgan hill. This is not anticipated to make it much farther, but there is a low potential for a brief period of MVFR CIGS towards morning. Tonight, winds decreasing and becoming west to southwest at OAK, and southeast at SJC. Thursday afternoon winds are expected to become northwest again at SJC again by 21 or 22Z.
Monterey Bay Terminals, MVFR stratus returning quickly this evening at both SNS and MRY. Breezy winds are slowly diminishing this evening and tonight. VFR conditions are expected to return in the afternoon on Thursday although confidence is low on the timing and it will likely be a similar duration to today.

Gale force gusts across the northern outer waters will ease tonight. Moderate northwest breezes will prevail elsewhere. Rough to very rough seas will continue in the outer waters through tonight before abating to become moderate to rough Thursday into Friday. Moderate to strong breezes are expected to continue through the weekend with the strongest winds in the north.
Ca, None. PZ, Small Craft Advisory until 3 AM PDT Thursday for Pt Arena to Pt Reyes 0-10 nm.
Gale Warning until 3 AM PDT Thursday for Pt Arena to Pt Reyes 10- 60 NM.
Small Craft Advisory until 9 AM PDT Thursday for Pigeon Pt to Pt Pinos 10-60 NM.
