.SHORT TERM...
Issued at 228 AM PDT Fri Aug 1 2025
(Today and tonight)

Very well-defined and deep marine layer persists this morning
penetrating well inland and providing a refreshing shot of heavy
drizzle along coastal areas overnight. In fact, several locations
along the coast and East Bay Hills have seen a few hundredths of an
inch of precip over the last 24 hours. There is potential for
another round of this weather tonight as high surface pressure over
the waters reinforces robust onshore flow and a subtle upward
vertical motion promotes a deep marine layer.

.LONG TERM...
Issued at 228 AM PDT Fri Aug 1 2025
(Saturday through Thursday)

Still on track for a quick bout of gusty winds Sunday and Monday as
a weak upper low moves in to the PacNW. There is a consistent trend
where guidance has been nudging this trough a bit further north,
limiting its impact on us. Sunday and Monday afternoons still look
to be rather gusty, especially along the coastal areas and known
windy spots such as the San Bruno Gap and Altamont Pass. Still not
thinking this will be an "advisory level" event, but definitely
worth a mention for those traveling and recreating.

Beyond the windy period Sunday and Monday, there is a confident
signal for a warming trend through the middle of next week, but this
will likely only take us to about 5 degrees or so above normal for
interior areas. Otherwise, it`s back to our boring pattern.

.AVIATION...
(18Z TAFS)
Issued at 1216 PM PDT Fri Aug 1 2025

Quiet and VFR conditions for interior locations, while coastal
sites are struggling to clear the stratus leaving them with,
with MVFR cigs. Expect this to hold through the afternoon and early
evening hours, which is when stratus will start to seep into some of
the valleys. MVFR to perhaps IFR cigs are expected again tonight at
most sites, though they may not arrive until early Saturday morning
just before sunrise. The forecast will rinse and repeat, with
stratus retreating to the coast by mid to late morning.


Vicinity of SFO...Stratus has eroded over the eastern side of the
range ring, including San Francisco Bay, while the western side
remains socked in with stratus. Will likely continue to see clouds
of FEW015 through the afternoon, leaving us with a period of VFR
conditions. Stratus is expected to return this evening, perhaps as
early as 3Z which is where we hinted at that possibility. The more
likely scenario, based on the latest guidance, is closer to 5-7Z
with conditions filling in shortly after that. Clearing is expected
to begin mid tomorrow morning, with VFR returning by late morning or
early afternoon. Gusty westerly winds are expected each afternoon
and evening, with gusts up to 20-25kt.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Well, stratus remains around MOnterey Bay
and has cleared from KSNS. This should likely hold through the rest
of the afternoon with stratus quickly returning this evening,
especially for KMRY if it actually stays scattered. Look
for MVFR and IFR cigs to return tonight and for conditions starting
to improve by mid to late morning.

.MARINE...
(Today through Wednesday)
Issued at 952 AM PDT Fri Aug 1 2025

Moderate to strong northwesterly breezes will prevail with
widespread near-gale to gale force gusts on Sunday and Monday.
