Area Forecast Discussion...UPDATED
National Weather Service San Francisco CA
532 AM PDT Mon Jun 16 2025

...New AVIATION...

.SYNOPSIS...
Issued at 306 AM PDT Mon Jun 16 2025

Pleasant weather continues into the new work week. Temperatures will
be near normal today, slightly above normal Tuesday and Wednesday,
then back to normal or slightly below normal for the end of the week
into the weekend.

&&

.SHORT TERM...
(Today and tonight)
Issued at 306 AM PDT Mon Jun 16 2025

Temperatures today will be near seasonal averages with sunny skies
inland and mostly a mix of sun and marine layer stratus along the
coast, especially the San Mateo coastline. The marine layer is pre
sent, however dry boundary layer air (PWATS ~ 25th percentile or
lower) will continue to hold off more widespread low level stratus
that is generally present during `June Gloom`. A weak trough axis
will push across our area this afternoon and evening resulting in
moderate onshore flow and gusty winds from late this morning through
later this evening across the Bay Area and higher elevations inland.
Despite the increased onshore flow the drier air aloft will help
keep widespread low marine stratus from developing again tonight.

&&

.LONG TERM...
(Tuesday through Sunday)
Issued at 306 AM PDT Mon Jun 16 2025

Relatively weak shortwave ridging will lift temperatures Tuesday and
Wednesday slightly above normal, with a passing shortwave trough
bringing temperatures back to or slightly below normal for the end
of the week into next weekend. Continuing the theme of PWATs well
below normal through most of the extended, it will be difficult to
identify exactly where the most impactful marine layer clouds will
develop on a day to day basis.

&&

.AVIATION...
(12Z TAFS)
Issued at 532 AM PDT Mon Jun 16 2025

Coastal stratus and patchy fog /MVFR-LIFR/ are moving inland on
onshore winds, the SFO-SAC pressure gradient is currently 3.2 mb.
The marine layer depth varies from near sea level to 1500 feet per
recent profiler data. Gusty onshore winds developing today, winds
easing tonight and Tuesday morning.

Vicinity of SFO...IFR ceiling to 1630z today, otherwise increasingly
gusty onshore wind today with gusts to 35 knots from late morning
through early to mid evening.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...IFR-LIFR in stratus and patchy fog
through late morning, MVFR-VFR during the afternoon. Stratus
/IFR/ redeveloping tonight and Tuesday morning. Onshore winds 5 to
10 knots increasing to 10 to 20 knots during the afternoon and
early evening, then decreasing to 5 to 10 knots tonight and
Tuesday morning.

&&

.MARINE...
(Today through Saturday)
Issued at 306 AM PDT Mon Jun 16 2025

Fresh to strong northwesterly breezes, near gale force gusts, and
moderate to rough seas will prevail through Thursday. Gale force
gusts are expected near the coastal jet regions of Point Reyes and
Point Sur.

&&

.FIRE WEATHER...
Issued at 556 PM PDT Sat Jun 14 2025

No real notable changes to the ongoing forecast fire weather wise.
Still highlighting elevated fire weather conditions across the
interior Central Coast. While not in our forecast area, a decent
veg fire developed and spread quickly to over 1k acres in SLO.
This could have easily happened in San Benito or Monterey
counties.

Observations over the last 24 hour and predicted weather continue
to show marine layer influence keeping fire weather conditions in
check for lower elevations and coastal areas. However, about
roughly 2k feet and farther inland conditions remain mild and dry
both day and night. On top of that is onshore flow leading to
breezy conditions each afternoon. Some of the winds are being
enhanced by topography leading to gustier flow in the valleys,
gaps, passes with 20-35 mph gusts.

Simply put, if you`re recreating outdoors, be one less spark in
these elevated fire weather conditions.
