Area Forecast Discussion
National Weather Service San Francisco CA
214 PM PDT Tue May 28 2024

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

.SYNOPSIS...
Issued at 150 PM 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 with an inland warming trend.

&&

.SHORT TERM...
(This evening through Wednesday)
Issued at 150 PM PDT Tue May 28 2024

The afternoon forecast update mostly fine-tuned the winds over the
marine environment, while the overland forecast remains on track.

Expect mostly sunny skies into the evening for all but the coastal
Monterey and Half Moon bays areas. The earlier clearing for some of
the more interior areas will make this afternoon slightly warmer
than yesterday, and act as the start of our mid-week warming
trend.

While the coast remains cool, areas inland will warm Wednesday
with the more interior valleys breaking into the mid to upper
80s. Luckily overnight lows mostly stick to the 50s, allowing for
relief from the heat.

&&

.LONG TERM...
(Wednesday night through next Monday)
Issued at 150 PM PDT Tue May 28 2024

Thursday looks to offer the warmest temperatures of the week as
inland areas break into the 90s, but the immediate coast looks to
remain in the 60s. Again with some fair overnight relief. The
patter shifts into the end of the week, allowing for a slow and
steady cooling trend into the weekend.

The extended forecast offers another, similar warming trend
arriving Monday and Tuesday next week. Temperatures from this
warming trend look to peak again in the 90s for the more interior
areas, while the coast sticks to the upper 50s and low 60s. This
looks to be followed my a much quicker cooling trend into the
mid-week.

.AVIATION...
(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...
(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.
