...New SYNOPSIS, SHORT TERM, LONG TERM...

.SYNOPSIS...
Issued at 103 PM PDT Fri Jun 6 2025

Mostly quiet conditions prevail through the forecast period with
warm temperatures inland and cool, seasonable temps along the
coast. Slight cooling trend by the middle of next week as a deeper
trough pattern develops off the West Coast.

.SHORT TERM...
(This evening through Saturday)
Issued at 103 PM PDT Fri Jun 6 2025

Stratus quo, deja vu, groundhog day, whatever you want to call
it. Inland areas heating up to comfortable and seasonable
temperatures today while the coastline is once again leaving folks
in a paralyzing state of "should I bring a jacket". Then they
don`t because it feels nice at first and end up regretting it 30
minutes later. This trend generally continues into the weekend
with inland locations heating up by a few more degrees while
coastal locations remain in this cool but nice state with near
normal temperatures. A few coastal locations will see temps a bit
more tolerable for short sleeves and shorts such as Santa Cruz,
Big Sur, and Monterey (for like a couple of hours). Are
convertible pants still a thing? I digress.

.LONG TERM...
(Saturday night through next Thursday)
Issued at 103 PM PDT Fri Jun 6 2025

Really not much change into the end of the weekend with the upper
level ridge mostly staying put, and nothing to drive the weak
closed low away. Therefore, the pattern is slow to revert. By the
middle of the week, guidance depicts a deeper open wave trough
that would kick off a cooling trend into late next week. Ensemble
guidance has been greatly confident in advertising this whole
pattern evolution over the next several days. All-in-all, most
people aren`t going to notice much day-to-day difference before
the middle of next week with the exception of the inland areas
recognizing that their car thermometer says 82 instead of 80.

.AVIATION...
(18Z TAFS)
Issued at 1014 AM PDT Fri Jun 6 2025

IFR/MVFR ceilings linger over the North Bay and Monterey Bay regions
this morning but are likely to return to VFR by late morning. The
exception will be at HAF where MVFR ceilings will persist through
much of the day. Onshore winds increase this afternoon and ease
after sunset. There is high confidence for MVFR/IFR ceilings to
return to the Monterey Bay terminals late this evening and the Bay
Area terminals early Saturday morning.

Vicinity of SFO...VFR conditions have returned to the Bay Area
terminals as of this writing with onshore winds expected to increase
through early afternoon. There is high confidence for ceilings to
return by early Saturday morning, generally in the MVFR range. VFR
conditions are likely to return by Saturday afternoon with
increasing west to northwest winds.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR ceilings linger at MRY and SNS. VFR
conditions are expected late this morning with an increase in
northwest winds. High confidence for an early return to MVFR
ceilings early this evening, lowering to IFR by early Saturday
morning.

.MARINE...
(Today through Wednesday)
Issued at 1014 AM PDT Fri Jun 6 2025

The pressure gradient has relaxed and buoys are now reporting a
gentle to moderate breeze across the coastal waters. Diurnal
effects will bring a fresh to strong SW breeze to the San
Francisco Bay over the next couple afternoons. Otherwise
conditions will be favorable through early next week when winds
start to build and a long period southwesterly swell arrives.
Winds and seas will rebuild more substantially mid to late next
week.

PZ...Small Craft Advisory until 9 PM PDT this evening for SF Bay N of
