.SHORT TERM...
Issued at 148 PM PDT Sat Jul 26 2025
(This evening through Sunday)

The forecast will  be mostly on repeat this period. The marine layer
is expected to compress Sunday into early next week falling to
around 1000ft +/- a couple of hundred feet. This will keep the
stratus creeping too far inland; however, a deepening marine looks
to return mid week. What does that mean, No Sky July continues and
we`ll start off August as Fogust. Cloudy nights, stratus retreating
to the coast during the day, and near seasonal to below seasonal
temperatures.

.AVIATION...
(18Z TAFS)
Issued at 1028 AM PDT Sat Jul 26 2025

Solid marine layer to start the day with widespread IFR to MVFR
conditions with a mix of drizzle to light rain at times. However,
latest trends from observations, satellite, and cams are showing
gradual improvement. Terminals LVK/SJC and southward will be
going VFR by 19Z if they haven`t already. SFO/OAK northward will
struggle to clear by 20Z with continued onshore flow and solid
stratus feed. The near term wrinkle in all of it is the stratus
deck over the waters is a mix of open/close cellular strato-cu.
Meaning, we`re seeing pockets of rapid clearing given some low
level mixing. That being said, confidence is moderate to high
(60-80%) that SFO/OAK will see at least a few hours of VFR this
afternoon. Fro tonight, more of the same with a marine layer
cloud deck returning early and persisting through most of the TAF
period.

Vicinity of SFO...CIGS have lifted, but still BKN. Will keep
previous 2030Z SCT time as it still looks reasonable. Cigs return
early this evening and then lower again by Sunday AM.

SFO Bridge Approach...Earlier clearing of approach, especially S
end of SF Bay.

Monterey Bay Terminals...Transitioning to VFR 18-19Z. Cigs return
early this evening.

.MARINE...
(Today through Thursday)
Issued at 931 AM PDT Sat Jul 26 2025

Light to moderate northwest winds remain over the coastal waters
as high pressure remains over the Eastern Pacific. Moderate seas
will prevail through the weekend then gradually increase next
week.
