.SHORT TERM...
Issued at 124 PM PST Wed Nov 26 2025
(This evening through Thursday)

Seeing less cloud cover compared to yesterday at this hour. Thus, a 
greater potential to reach our high temperatures this afternoon.
Temperatures will warm into the lower 70s across the Central Coast 
and Santa Cruz Area, approach 70 degrees F in the North Bay, and 60s 
across much of the remainder of the region. This is as moderate, dry 
offshore flow persist in the higher elevations and a mid/upper level 
ridge axis is currently in place aloft. 

Tonight, again expecting less widespread coverage of low clouds and 
fog. However, cannot rule out patchy to areas of dense fog across 
the North Bay valleys, East Bay valleys, and the Santa Clara Valley 
overnight. Temperatures overnight are forecast to be mostly in the 
upper 30s to lower 40s. In the higher elevations, we can expect 
temperatures to be in the mid 50s to lower 60s due to continued 
offshore winds. 

Any low clouds and/or fog that does develop will give way to mostly 
sunny skies by Thursday afternoon. This will again allow temperatures 
to be up to 10 degrees above seasonal averages. Overall, within a 
few degrees of what today's forecast high temperatures will be.

.LONG TERM...
Issued at 124 PM PST Wed Nov 26 2025
(Thursday night through next Tuesday)

Thursday night and into Friday an upper level trough is forecast to 
move into the Pacific Northwest. This will bring a weak, dry frontal 
boundary across the Bay Area and Central Coast cooling temperatures 
to near seasonal averages. A general troughing pattern will persist 
over the region through early next week as high pressure builds 
offshore. Thus, look for weak to moderate offshore flow in the 
higher elevations, dry conditions, and temperatures near seasonal 
averages.

.AVIATION...
(00Z TAFS)
Issued at 355 PM PST Wed Nov 26 2025

Currently VFR across the region with localized fog returning to the 
North and East Bays tonight. Moderate confidence that fog cover will 
continue to diminish tonight as offshore winds bring drier air into 
the region. Guidance does show some potential for visibilities to 
drop into MVFR territory across the rest of the Bay Area but 
confidence is low that widespread fog will develop. Main adjustment 
was to add a tempo for lowered visibilities to SJC early tomorrow 
morning. Otherwise, winds generally stay light and offshore through 
the TAF period with breezier winds developing during the 
afternoon/evening hours. 

Vicinity of SFO...VFR with some potential for MVFR conditions 
overnight. Fog is not expected to impact the terminal but 
visibilities may drop below 6SM between 10Z-16Z. Winds remain light 
and offshore overnight with moderate onshore winds redeveloping 
during the day.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR through the TAF period. Winds remain 
offshore with light winds at MRY and light to moderate at SNS. 
Drainage winds are expected to develop at SNS early tomorrow morning 
and persist through the early afternoon.

.MARINE...
(Tonight through next Monday)
Issued at 355 PM PST Wed Nov 26 2025

Lingering high pressure along the coast will keep gentle to
moderate northerly flow over the coastal waters through tonight.
Patchy dense fog will be possible again tonight, especially in the
West Delta. A weak dissipating cold front will bring increasing
northerly winds Thanksgiving day lasting into Friday.
Additionally, a squared seas state will develop late Thanksgiving
day leading to hazardous conditions.
