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

.SYNOPSIS...
Issued at 131 AM PDT Fri Jun 6 2025

A slight warming trend continues through the early part of next
week. Temperatures rise slightly above seasonal averages inland
while coastal areas remain near or slightly below seasonal averages.
A cooling trend is likely by the middle of next week.

&&

.SHORT TERM...
(Today and tonight)
Issued at 131 AM PDT Fri Jun 6 2025

Satellite imagery shows stratus developing across the coastal
valleys and beginning to spread inland, with the clouds mixing out
after sunrise through the morning hours. Morning lows continue to
hover into the upper 40s to middle 50s across the lower elevations,
perhaps as warm as 60 in the highest peaks. A slight warming trend
is expected to continue today with an upper level ridge building
into the Pacific Northwest and southwestern Canada; high
temperatures today reach the upper 70s to the middle 80s in the
inland valleys, into the lower 90s for the warmest spots, around the
70s across the San Francisco Bayshore, and into the lower to middle
60s along the Pacific coast. Winds should be generally light and
diurnal, with some stronger gusts this afternoon and evening of
around 20-25 mph through the gaps and passes, along the San Pablo
and northern San Francisco Bayshores, and the northern Salinas
Valley. With the marine layer remaining deep (around 1500-2000
feet), marine layer stratus should return to most of the coastal
valleys tonight.

&&

.LONG TERM...
(Saturday through Thursday)
Issued at 131 AM PDT Fri Jun 6 2025

The upper level ridge will build across the northwestern United
States and southwestern Canada through the early part of next week.
However, an embedded jet will contribute to the formation of a
cutoff low meandering off the California coast, helping to moderate
the influence of the upper level ridge and reinforce the marine
layer. Thus, high temperatures will continue to ride near or
slightly above seasonal averages away from the immediate coastal
region, where the sea breeze will keep temperatures slightly below
seasonal averages. The warmest temperatures are expected early next
week with highs in the inland valleys reaching the middle to upper
80s, up to the upper 90s in the warmest spots of southern Monterey
County. By the middle of next week, a cooling trend should begin as
the upper level ridge erodes and an troughing pattern develops over
the West Coast.

&&

.AVIATION...
(06Z TAFS)
Issued at 1029 PM PDT Thu Jun 5 2025

Widespread MVFR-IFR conditions are expected overnight. Low
confidence but high resolution guidance does continue to indicate a
chance for LIFR CIGs to develop overnight. CIGs will initially start
out MVFR before lowering and becoming IFR overnight. Not currently
anticipating widespread fog/LIFR conditions but patchy reductions in
visibility may be possible directly along the coastline. Stratus
will return early tomorrow evening with CIGs expected to reach HAF,
MRY, and SNS at the end of this TAF period. Confidence is low to
moderate for HAF with guidance showing a slight chance of MVFR CIGs
continuing through the entire TAF period. For now, leaning towards
HAF clearing by late tomorrow morning but stratus looks to return by
the early evening hours. Light, variable at times, winds are
expected overnight before moderate onshore winds return during the
day tomorrow.

Vicinity of SFO...Stratus has started to fill in through the Golden
Gate Bridge and is expected to fill in over the SF Bay by early
tomorrow morning. Current thinking is that stratus will not reach
SFO until around 10Z but patchy/temporary stratus may impact the
airport prior to that. CIGs look to clear by mid to late morning
with VFR conditions through the remainder of the day. Guidance
indicates stratus may return towards the end of the TAF period with
confidence increasing after 09Z. Winds continue to ease overnight
with moderate onshore winds to return during the day tomorrow.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...MVFR-IFR conditions are expected overnight
with CIGs gradually lowering from MVFR to IFR during the early
morning hours. CIGs start to rise mid tomorrow morning with clearing
expected by mid to late morning. Light, variable winds are expected
overnight with moderate onshore flow returning during the day.
Stratus is expected to return tomorrow evening with confidence

&&

.MARINE...
(Tonight through next Wednesday)
Issued at 1029 PM PDT Thu Jun 5 2025

Winds have eased over the coastal waters with the exception of the
northern outer coastal waters where a SCA remains in effect
through  early Friday morning for locally fresh to strong gusts.
Diurnally  breezy winds are expected to develop again over the San
Pablo Bay  tomorrow afternoon with fresh to strong gusts expected.
Otherwise,  conditions will remain mostly favorable over the
coastal waters  through early next week when winds start to build
and a long period  northwesterly swell arrives.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
CA...None.
PZ...Small Craft Advisory from 3 PM this afternoon to 9 PM PDT this
     evening for SF Bay N of Bay Bridge.

     Small Craft Advisory until 3 AM PDT early this morning for Pt
     Arena to Pt Reyes 10-60 NM.
