What forecasters said that day

The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS San Francisco Bay Area, CA wrote its last area forecast discussion before this gale warning went out at Oct 13, 5:21 PM PDT, 3 hours 52 minutes earlier.

Area forecast discussion, Oct 13, 5:21 PM PDT, 3 hours 52 minutes before
Area Forecast Discussion
National Weather Service San Francisco Bay Area
521 PM PDT Tue Oct 13 2020

.SYNOPSIS...Warming and drying trend will continue through Friday
as high pressure builds back across the region. Offshore winds
will also develop, becoming locally strong and gusty in the North
and East Bay, especially in the hills, from early on Wednesday
through Friday morning. Strongest winds are forecast from
Wednesday evening through Thursday morning. These winds will
occur in conjunction with a very dry air mass, resulting in
critical fire weather conditions.

&&

.DISCUSSION...As of 02:00 PM PDT Tuesday...Water vapor imagery
shows high pressure starting to build over California today, with
sunny as well as dry and warmer conditions prevailing across the
Central Coast this afternoon. Temperatures are running up to 4
degrees warmer than this time yesterday, with Santa Rosa upward of
7 degrees warmer. This additional warming is likely due to some
light offshore winds there, aiding in the adiabatic warming. These
north to northeast winds will continue to develop across the
region tonight, becoming locally gusty in the hills by morning.

This ridge will continue to build along the West Coast this week,
and will be dominant weather feature through at least Friday, with
even warmer and drier conditions developing as well as stronger
offshore winds. Looking specifically at the temperatures for the
time being, temperatures will warm a few degrees each day, with 850
mb temperatures warm to near 23 degrees C by Thursday. This means
that with no marine layer to speak of that most areas will be 12
to 20 degrees warmer than normal for this time of year. Will need
to take a closer look at record temperatures for Thursday and
Friday, but we may have a few locations flirting with those kinds
of numbers. If that is the case, will likely need to consider
issuing a heat advisory, but for now, the heat risk is only
indicating a moderate risk for those that are sensitive to the
heat.

The other main story this week will be with the developing
offshore winds over the next few days, and the critical fire
weather conditions.. The 12z NAM and WRF show the strongest
offshore gradient Wednesday night into Thursday morning, with KSFO
to KWMC upwards of -16.5 mb by 12z Thursday. That gradient
combined with 925 mb winds in the 30 to 40 kt range across North
and East Bay, felt confident in upgrading the Fire Weather Watch
to a Red Flag Warning as extremely dry air will accompany these
winds. Daytime humidity values will likely fall into the single
digits and teens, with overnight RH values struggling to recover
into the teens and 20 percent range. While the strongest winds
will likely be focused on the North and East Bay Mountains and
Hills, with gusts up to 55 mph possible over the highest ridges
and favored peaks, cannot rule out some gusty conditions in the
Santa Cruz Mountains as well. These winds will likely gust up to
45 mph in the windiest locations. Also expanded the Red Flag
Warning to include the North and East Bay Valleys. Confidence is
there that these areas will see the extremely low humidity values,
but the winds are the question. Given that it does not take much
winds with those kind of humidity values, and believe gusts up to
30 mph are not out of the question, have included the North and
East Bay valleys as well.

This ridge will shift farther to the west this weekend, allowing
cooler conditions to finally return. At this time, still believe
inland areas will be quite warm on Saturday, but most areas return
to normal ranges by Sunday. These cooler and more seasonal
conditions will prevail through the first part of next week.
Unfortunately, it looks to remain dry through the period. Palmer

&&

.AVIATION...As of 5:20 PM PDT Tuesday...For 00Z TAFs. VFR with
clear skies throughout the region. These conditions will continue
throughout the TAF period, with NNE winds aloft keeping the dry
airmass in place. As noted in previous discussion, LLWS will be a
factor at several terminals overnight (KSTS/KLVK/KAPC/KSJC) into
tomorrow morning with light winds at the surface and 20kt-30kt
northerly winds at 1000ft-2000ft AGL. This event is expected to
last through Friday morning, so additional LLWS in subsequent TAF
packages possible. Winds at the surface are moderate onshore with
breezier conditions through coastal gaps. Winds will subside
overnight.

Vicinity of KSFO...VFR through the TAF period. WNW winds at 18 kt
continuing through early evening and subsiding overnight. Surface
onshore flow continuing tomorrow.

SFO Bridge Approach...Similar to KSFO.

Monterey Bay Terminals... VFR. Light to moderate winds, easing
overnight with VFR conditions. Models hint at a little cloud
cover build up along the coast from the northwest winds over the
ocean, but no impacts are expected at terminals. Pattern continues
through tomorrow.

&&

.FIRE WEATHER...As of 02:15 PM PDT Tuesday...Primary period of
concern is from Wednesday morning through Friday morning when
models develop locally strong and gusty north to northeast winds
in the hills, especially the North Bay Mountains and East Bay
Hills, but also at the higher elevations of the Santa Cruz
Mountains. Latest NAM starts to ramp up northerly winds in the
hills early Wednesday morning, especially over Napa County, but
also farther south into the Diablo Range. Significantly stronger
and gustier winds are then expected to develop and become more
widespread in the hills Wednesday evening and peak overnight
Wednesday night into early Thursday morning, then diminish during
the day on Thursday. An uptick in wind speeds is likely again on
Thursday night, but winds then are not expected to be as strong as
those Wednesday night. In addition to gusty offshore winds, an
extremely dry air mass is forecast to move in from the north and
northeast. Afternoon relative humidity values beginning Wednesday
are forecast to drop into the single digits and teens, with very
poor overnight recoveries anticipated. Based on these expected
developments, critical fire weather conditions will likely occur

Hills, and Santa Cruz Mountains between Wednesday Morning and
Friday Morning. The Fire Weather Watch has been upgraded to a Red
Flag Warning for the North Bay Mountains, East Bay Hills and Santa
Cruz Mountains from early Wednesday morning to Friday morning. A
Red Flag Warning was also issued for the North and East Bay
Valleys, as extremely dry conditions will develop there, with some
locally gusty winds possible as well.

Winds are forecast to subside in all areas by Friday afternoon and
temperatures are forecast to cool next weekend.
