Area Forecast Discussion
National Weather Service San Francisco CA
1050 PM PDT Tue Oct 15 2024

...New AVIATION...

.SYNOPSIS...
Issued at 114 PM PDT Tue Oct 15 2024

Mild weather through midweek, critical fire weather conditions
expected by the end of the week. Fire Weather Watch has been
upgraded to a Red Flag Warning, in effect Thursday night through
Saturday.

&&

.UPDATE...
Issued at 910 PM PDT Tue Oct 15 2024

Not much to update from the previous discussion. Models and
ensemble members continue to increase confidence in significant
offshore winds in the second half of the work week. Winds are also
looking to be strong over the ocean, leading to aggressive ocean
hazards with gale-force to storm-force marine wind thresholds
possible.

-Murdock

&&

.SHORT TERM...
(This evening through Wednesday)
Issued at 114 PM PDT Tue Oct 15 2024

Mild and fairly quiet conditions continue through the middle of
the week. A shortwave trough out ahead of the main upper low is
progged to move across the region Wednesday morning, which will
result in a slight chance of drizzle across the Bay Area, North
Bay, and coastal areas. A few lucky locations in the North Bay and
around San Francisco may see a passing light shower through
midday Wednesday, but most places are not expected to see much in
the way of beneficial wetting rain.

&&

.LONG TERM...
(Wednesday night through next Monday)
Issued at 114 PM PDT Tue Oct 15 2024

Thursday is the transition day where things start to become more
interesting. Following the passage of the weak shortwave
Wednesday, a deep upper low is progged to move into the Great
Basin from the northwest. Winds are set to increase as the surface
front approaches through the day Thursday, but humidity will
remain relatively high as winds will be out of the northwest
initially. By Thursday evening, the rather vigorous trough axis
sweeps through the state by around sunset, which is when we should
see a more substantial increase in winds. Strong surface high
pressure will quickly build in the wake of the front overnight
Thursday, promoting a more north-northeasterly wind component.
This will be the defining moment when humidities will start to
drop quickly to critical levels through Friday morning. The
offshore-oriented pressure gradient from Redding to Sacramento is
expected to peak Friday morning near the 99th percentile, further
bolstering confidence in a potentially high impact event for the
North Bay interior mountains. On a more broad scale, the pressure
gradient from San Francisco to Winnemucca is forecast to be
offshore-oriented from Friday morning until Saturday night,
peaking around Friday afternoon. Nothing particularly notable on
the extreme scale, but there is reasonable agreement among
guidance...once again increasing the confidence in the large scale
impact of this offshore wind event. As it stands with current
guidance, the most worrisome areas are likely to be the North Bay
interior mountains, the East Bay hills and Diablo Range, and the
SF Peninsula. Higher terrain and ridges will be especially
vulnerable, with gusts up to 65 mph possible. Otherwise, winds
will be in the 25-35 mph range, with gusts to 45. The offshore
gradient weakens and order is restored by late Saturday into
Sunday as the upper low weakens and moves inland.

&&

.AVIATION...
(06Z TAFS)
Issued at 1031 PM PDT Tue Oct 15 2024

The tail end of a cold front is approaching the North Bay tonight
and may bring a few rain drops over the next 24 hours. The main
effects on aviation weather will be the increased mid and high
cloud coverage and a deepening marine layer in response to the
lower atmospheric pressure. Despite the increasing cloud cover,
the deeper marine layer should result in less ceiling and
visibility issues as compared to last night. The front likely
won't make it to the southern terminals before LIFR ceilings roll
in overnight, however.

Vicinity of SFO...VFR expected through the TAF period, but there
is an increasing chance of a sunrise surprise, with IFR ceilings
possible between 12 and 18Z. Otherwise standard onshore winds are
expected to pick up in the afternoon. Looking ahead, much
stronger winds are expected Thursday evening, which may trigger an
airport weather warning.

SFO Bridge Approach...Similar to SFO.

Monterey Bay Terminals...Clear skies at the moment, but the night
fog imagery is showing increasing low cloud cover building at both
MRY and SNS. Expect IFR-LIFR ceilings to dominate after midnight
(07Z). Otherwise mid and high cloud coverage will arrive as the
low clouds clear midday.

&&

.MARINE...
(Tonight through next Monday)
Issued at 910 PM PDT Tue Oct 15 2024

Rough seas continue to diminish across the outer waters with
fresh to moderate NW breeze. Conditions will gradually improve
through early Wednesday as the long period swell abates but this
reprieve will be short lived as conditions deteriorate again by
Wednesday night. Gusty winds will start to increase and will
become hazardous into Friday, with the potential for gale and
possible storm force winds.

&&

.FIRE WEATHER...
Issued at 149 AM PDT Tue Oct 15 2024

A Fire Weather Watch is in effect from 11 AM Thursday until 8 PM
Saturday. Normal temperatures, excellent relative humidity
recoveries, and onshore flow will keep fire weather concerns at
ease through Wednesday. Fire weather concerns will be high
Thursday through the weekend as an inside slider event comes to
town. While fuels are near average, they are expected to dry out
as the week progresses. Northerly winds will develop Thursday as
a deep upper-level low digs into the Great Basin. As this digs
further south and becomes a cutoff low, winds will become
northeasterly/offshore. These winds will lead to rapid drying,
compressional warming, poor relative humidity recovery and
retention as low as 15%, and a nonexistent marine layer. The
windiest timeframes will be Thursday night into Friday morning and
Friday night into Saturday morning with winds largely on the
order of 20-30 mph with gusts to 40 mph, isolated gusts to 50 mph
across the highest terrain and ridgetops and through gaps and
passes.

&&

.BEACHES...
Issued at 1050 AM PDT Tue Oct 15 2024

Long period northwesterly swell of 13-17 seconds with wave heights
approaching 10 feet will result in a moderate risk of sneaker waves
across all Pacific Coast beaches through at least Wednesday. Large
waves can sweep across the beach without warning, pulling people
into the sea from rocks, jetties, and beaches. Beachgoers should
always remember to observe the ocean for 20 minutes before relaxing
near the water, keep your pets on a leash and away from the water,
and never turn your back on the ocean.

&&

.MTR WATCHES/WARNINGS/ADVISORIES...
