...New AVIATION, MARINE...

.SYNOPSIS...
Issued at 255 AM PDT Tue May 28 2024

Near seasonal temps inland again today with the coast remaining
cool under a well-formed marine layer. Pleasant weather continues
through the week.

&&

.SHORT TERM...
(Today and tonight)
Issued at 255 AM PDT Tue May 28 2024

Another day with temperatures right around seasonal averages
across inland areas. Coastal areas will still be under the
influence of a stout marine layer with cool temps in the upper
50s to near 60. Passing upper trough through the PacNW flattens
out our ridge a bit, putting a slight pause on the warming as we
move into the middle part of the week. Overall no major changes
to the short term period.

&&

.LONG TERM...
(Wednesday through Monday)
Issued at 255 AM PDT Tue May 28 2024

The cooling trend will be short-lived as the flattened ridge
begins to build back over the region with warming 850 mb temps and
rising 500 mb heights. Still looks like night/morning clouds with
inland afternoon sunshine will persist. The warming trend will
continue into this weekend with the warmest temps expected
Thursday and Friday. Far inland locations will reach the low 90s
by week`s end.

(18Z TAFS)
Issued at 1056 AM PDT Tue May 28 2024

Currently VFR at all terminals except the Monterey Bay terminals of
MRY and SNS which have been slow to clear of IFR and MVFR stratus,
respectively. Moderate confidence in VFR through the TAF period at
all terminals with the exception of the Monterey Bay terminals of
MRY and SNS. Winds will be gusty out of the west/northwest this
afternoon and evening with gusts of 20-25 knots to be expected at
all terminals, 30 knots to be expected at SFO.

Vicinity of SFO...Currently VFR with westerly flow. Moderate
confidence in VFR through the TAF period. Westerly winds will
continue to be on the increase with gusts up to 30 knots to be
expected this afternoon and evening. Winds will become less gusty
overnight, slightly diminishing through the late morning hours
before ramping back up again tomorrow afternoon.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Currently IFR with northwesterly flow at
MRY and MVFR with northerly flow at SNS. Breezy to gusty westerly
winds will prevail through the TAF period. High confidence that both
terminals will receive at least a low-end MVFR ceiling overnight
with lower confidence on exact timing and if the ceiling will
further deteriorate to IFR.

.MARINE...
-- Changed Discussion --
(Today through Sunday)
Issued at 1056 AM PDT Tue May 28 2024

Strengthening surface high pressure over the Eastern Pacific Ocean
in addition to an upper-level trough will allow for strong
northwesterly winds to prevail today and tomorrow with gale force
gusts especially possible over the northern zones and outer
waters.  This surface high pressure will weaken and retrograde to
the west  heading into the weekend allowing for northwesterly
winds to  slightly diminish. Significant wave heights will build
to 12 to  14 feet by Thursday with an abating trend set for Friday
into the  weekend.
