What a contrast from yesterday to today. Wall to wall sunshine blankets the Bay Area and Central Coast this afternoon. Stronger N-S and dissipating front helped to get rid of the coastal stratus. Increased sunshine and lack of natural A/C aided in generally warmer temperatures this afternoon. Pretty impressive 24 hour trends across the North Bay with many Sonoma Co sites 10-20 degrees warmer than yesterday.
For tonight and into Thursday, stratus way offshore will inch closer with additional stratus developing along the coast. Not expecting a full on marine layer push, but patchy stratus. Most coverage will be along the SF Peninsula Coast and Monterey Bay region. For Thursday, AM clouds will fade quickly leading to another sunny day across the region. Temperatures will nudge upwards by a few degrees. Far interior locations will have no issues reaching the upper 80s to mid 90s.

Thursday night into Friday as a little bit of rinse and repeat with some patchy coastal marine layer clouds and afternoon sunshine. Temperatures will be similar to Thursday: 60s to near 80 coast/bays and 80s to mid 90s inland.
Still looking at a notable pattern change over the weekend with regards to temperatures. An upper level low/trough currently in the Gulf of AK will move through that PacNW and ultimately CA. Lower 500mb heights, deeper marine layer, colder 850mb temps will yield a drop in temperatures across the board - roughly 5-10 deg from Friday to Saturday. A more subtle cooling trend will continue into early next week. The trough will also bring more widespread night/morning clouds with coastal drizzle possible. Longer range ensemble guidance continues to suggest a few showers around the region Monday into Tuesday, but confidence is generally less than 20% at this point. If it does happen it won't be much in the way of precip.

Cloud cover continues to erode with widespread VFR expected into the afternoon. Moderate to breezy winds are expected at most site this afternoon, with HAF and SFO seeing much stronger winds building in the mid afternoon. Expect some passing high clouds through the day. Winds reduce into the night becoming mostly light, aside from HAF and SFO which stay breezy until early Thursday. CIGs will struggle to return tonight, but look to affect HAF and the Monterey Bay terminals. Some scattered clouds look to affect the SF Bay terminals, but confidence is low on persistent cloud cover. GIGs look to lift and begins to erode again in the late morning and early afternoon on Thursday.
Vicinity of SFO, Strong west winds build through the afternoon with gusts peaking around 38 kts from the mid afternoon and into the night before reducing back down to 24 kt gusts. Winds reduce further into the night, becoming more moderate. Scattered low clouds will pass near the terminal overnight, but don't look to fill. This cloud cover erodes into Thursday afternoon as breezy winds build.
SFO Bridge Approach, Similar to SFO.
Monterey Bay Terminals, VFR and breezy winds last into the evening before winds weaken and MFVR/IFR CIGs move over the terminals. Winds CIGs lower slightly overnight, with fair chances of mist slightly affecting visibilities. CIGs look to lift and erode late Thursday
