.SYNOPSIS...
Issued at 1257 PM PDT Fri Jun 20 2025

Seasonably cool temperatures through this weekend with windy
conditions. Elevated fire weather concerns continue into Sunday
morning as gusty winds combine with dry conditions. Return to
normal temps and quiet conditions by early next week.

.UPDATE...
Issued at 917 PM PDT Fri Jun 20 2025

It has been a windy day across the Bay Area with SFO notably gusting
to 53 mph at 7:56 PM this evening. Winds will remain gusty overnight
before peaking Saturday morning/afternoon. The overall forecast
remains on track with winds set to diminish Sunday into next week as
an upper level trough moves eastward. In terms of fire weather,
daytime relative humidity values dropped into the teens to 20s
across the North Bay Interior Mountains and interior Central Coast.
Fire weather conditions will remain near critical through Saturday
across the higher elevations of the North Bay Interior Mountains,
Interior Central Coast, and East Bay Hills as gusty winds and dry
conditions continue.

.SHORT TERM...
(This evening through Saturday)
Issued at 1257 PM PDT Fri Jun 20 2025

Mostly clear skies across the region today a gusty NW winds ramp
up. Current winds gusting in the 25-35 mph range across some of
the more wind-prone gaps and passes. Most notably up to about 40
mph at Altamont. Winds are expected to remain gusty through
tonight as a deep upper low digs into the Great Basin. Due to the
positioning of the low and juxtaposition of the upper level jet,
winds will largely remain onshore through the event, which is a
bit of a silver lining, keeping the marine layer moisture present
below about 2000 feet. For areas above the marine layer, very dry
afternoon RH and limited overnight recovery will present an
elevated fire weather threat thanks to dry grasses and shrubbery.

.LONG TERM...
(Saturday night through next Thursday)
Issued at 1257 PM PDT Fri Jun 20 2025

The peak of the winds looks to be Saturday during the early
morning hours, but gusty conditions will linger through into
Sunday morning. Towards the end of the event Monday morning,
there is a small chance that the winds make a turn towards a more
offshore direction, but by the time the surface pressure gradient
supports this, much of the upper level support from the system
will have moved on. Therefore, we aren`t expecting any offshore
wind component Monday morning to have much more than a very minor
impact as of this forecast issuance. For the rest of the period, a
more "normal" pattern is restore as a ridge builds over our region
and subtle troughing to the north subdues any substantial
warming. Thus, we return to seasonable temperatures and relatively
quiet conditions next week.

.AVIATION...
(06Z TAFS)
Issued at 1006 PM PDT Fri Jun 20 2025

VFR through the TAF period. Interior winds are becoming more
moderate while winds along the coast are reducing but will still be
breezy and gusty. However, winds aloft remain strong for much of the
night, causing LLWS concerns, specifically at STS, which will have
strong winds at 1000 ft AGL. Winds aloft and at the surface reduce
further into Saturday morning, easing LLWS concerns. Winds build
across the region again into Saturday afternoon, but gusts won`t be
as strong as the Friday afternoon winds. The widespread breezy
conditions linger along the coast and in the North Bay valleys into
Saturday night, but ease for more interior areas.

Vicinity of SFO...VFR through the TAF period. Winds and gusts are
reducing but are still strong. Expect gusts to cut off and winds to
reduce slightly into early Saturday, keeping winds moderate through
the morning and into the early afternoon. Gusty winds return for
Saturday afternoon with around 30 kt gusts on top of 24 kt winds.
These winds and gusts reduce into the early night.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...VFR through the TAF period. Breezy and
gusty winds last into the night before reducing, becoming moderate
for MRY, but still seeing some southwest breezes at SNS. Cloud cover
looks to form just outside of MRY in the late night and early
morning to the south and east, but does not look to fill over MRY.
Skies clear into the mid morning. Breezy winds return in the mid
afternoon and reduce again that night.

&&

.MARINE...
(Tonight through next Thursday)
Issued at 917 PM PDT Fri Jun 20 2025

Strong gusts and rough seas are producing hazardous marine
conditions continue through the first half of Sunday before winds
reduce. Seas look to be slower to ease but will improve into the
next work week. Breezy but less strong winds linger for the first
part of the next work week as well.

&&

.FIRE WEATHER...
Issued at 323 AM PDT Fri Jun 20 2025

Elevated fire weather conditions continue today across the
interior becoming more widespread on Saturday, with RH values
around 30% expected across the interior of the East Bay south
through the Gabilan Range, along with the Santa Lucia mountains
this afternoon. Gusty winds above the marine layer and elevated
interior locations will once again be around 25 to 40 mph with
less coverage today than Thursday. Brief periods of critical fire
weather conditions are possible with daytime relative humidities
of 15 to 25% in the interior. However, continuing marine layer
influence, especially during the night, and the fact that winds
remain onshore, mean that widespread critical fire conditions do
not develop across the district. Gusty winds begin to subside
somewhat on Saturday, but the upper level pattern will lead to
more northerly winds developing across the region. As with
Thursday`s fire weather threat, widespread critical fire weather
conditions are not expected within the district, although the fire
weather threat will increase once again for areas closer to the
Central Valley. The fire weather threat will continue to diminish
Sunday into the early part of next week with the gusty winds
further relaxing, although humidity values in the interior will be
slow to rise.
