.SHORT TERM...
Issued at 1203 PM PST Thu Feb 26 2026
(This evening through Friday)

Now that the low clouds and areas of dense fog are improving, 
expecting the warm up to persist across the region through the 
afternoon. Temperatures are forecast to be in the upper 60s to lower 
70s across much of the North Bay and San Francisco Bay Area with 
interior areas of the Central Coast likely to warm into the upper 
70s (cannot rule out a few of the warmest locations reaching or 
exceeding 80 deg F). 

Tonight, we are expecting less widespread coverage of fog as the 
high pressure aloft continues to build and precipitable water values 
(PWAT) of 1"-1.15" shift northward across the North Bay. This is 
where we have the greatest potential for patchy fog early Friday 
morning. In addition, mid-to-high level clouds will increase 
throughout the night and linger into the upcoming weekend. 

By Friday, forecast to be the warmest day across the region, 
temperatures will likely warm into the low-to-mid 70s across the 
North Bay, East Bay and San Francisco with the San Francisco 
Bayshore warming and the rest of the region warming into the mid-to-
upper 70s. The greatest potential for areas to exceed 80 deg F is in 
the Santa Cruz Mountains and interior portions of the Central Coast. 
These temperatures are some 10-15 degrees F above average with the 
higher terrain up to 20 degrees.

.LONG TERM...
Issued at 1203 PM PST Thu Feb 26 2026
(Friday night through next Wednesday)

Temperatures cool slightly on Saturday, but only by a few degrees 
ahead of an approaching mid/upper level cut off low. The low 
pressure system will move into northern California and Oregon by 
Sunday evening and into early Monday morning. This will bring 
cooler, unsettled weather across the Bay Area and Central Coast. 
Afternoon temperatures both Sunday and Monday look to trend closer 
to seasonal averages. As far as precipitation goes, we are not 
expecting much rain at all from this system as probabilities remain 
very low for widespread rain. However, the North Bay and the coastal 
ranges look to have the greatest potential for for receiving rain 
from Sunday afternoon through Monday morning. 

Confidence beyond Tuesday lessens, yet shortwave ridging across the 
region is expected to warm temperatures slightly. However, 
troughiness looks to return for the latter half of the upcoming 
week. However, widespread rainfall is not looking likely.

.AVIATION...
(00Z TAFS)
Issued at 415 PM PST Thu Feb 26 2026

Widespread VFR lasts into the night with high clouds building once 
again. Light to moderate winds become lighter into the night with 
directions at most sites going variable. Pockets of inconsistent fog 
will be possible in some of the more interior sites into Friday 
morning but look to erode into the late morning, leading to 
widespread VFR. Winds build slightly into Friday afternoon

Vicinity of SFO...Expect light to moderate northwest winds well into 
the night before winds become light and variable. As the winds 
weaken, some pockets of mist will affect visibilities. VFR returns in 
the late morning as moderate northwest winds return. Winds reduce 
again and become light and variable into the night.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Winds become light and variable into the 
night with some slight reductions in visibilities possible, 
particularly in the Salinas Valley. Visibilities improve into Friday 
afternoon as light to moderate east to northeast winds build.

.MARINE...
(Tonight through next Wednesday)
Issued at 415 PM PST Thu Feb 26 2026

Light to moderate winds continue across the waters through the
weekend and into the next work week. Localized fresh gusts will
affect the southern waters into the weekend. Low to moderate seas
continue into next week. Drizzle to light rain will be possible
across the northernmost waters this weekend.
