What forecasters said that day

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

NWS Los Angeles, CA wrote its last area forecast discussion before this high wind warning went out at Nov 25, 11:31 PM PST, 4 hours 1 minute earlier.

Area forecast discussion, Nov 25, 11:31 PM PST, 4 hours 1 minute before
Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
1131 PM PST Wed Nov 25 2020

.SYNOPSIS...25/1129 PM.

There will be overnight and morning patchy low clouds and fog
along the coast and particularly south of Point Conception.
Gusty Santa Ana winds will develop on Thursday, peaking late
Thursday night into Friday morning but continuing through at least
Saturday. Afternoon temperatures will warm into the weekend.

&&

.SHORT TERM (WED-SAT)...25/801 PM.

***UPDATE***

A quiet evening across Southwest California leading into the Santa
Ana event developing on Thursday. Satellite difference channels
show patchy low clouds just offshore from Ventura County and along
the LA coast, but so far has not moved onshore. Believe any low
cloud coverage will be patchy overnight, possibly moving inland
across the LA Basin, but dissipating quickly during the morning
hours. Gusty north winds are noted over the usual north wind
magnet areas, including the western Santa Barbara South Coast and
the I-5 Corridor. Gusty west winds are funneling into the Antelope
Valley. All of these areas are showing wind gusts between 25 to 35
mph this evening. The north winds will diminish fairly quickly by
around 3am, then increase from the northeast over the remainder
of the LA Mountains. A strong jump in wind speeds is forecast by
the WRF by around 8am, with winds spreading over the valleys and
down to the coastal areas of Ventura and LA Counties.

The mountains and foothills of SBA and SLO counties will also see
gusty northeast to east winds later this evening through Thursday,
but at much lower speeds than those expected further south,
generally 15 to 25 mph with gusts up to 35 mph over the higher
mountains. LA and Ventura Counties should see gusts 35 to 45 mph
for the coast and valleys on Thursday, with gusts 50-55 mph over
the mountains. Winds will increase further Thursday night into
Friday, with High Wind Warnings likely for the mountains during
that time.

***From Previous Discussion***

NW winds will start up first in the LA/Ventura mountains then
spread quickly into the valleys and eventually to the coast,
though how fast this happens will depend on the stubbornness of
the marine layer. If low clouds fail to reform or are just patchy
at best that's a good sign that winds will reach the coast much
sooner, but a solid low cloud deck would delay that arrival
potentially by several hours.

With this in mind went with wind advisories for most LA/Ventura
areas Thursday (minus the Antelope and San Gabriel valleys at
least initially), starting first in the mountains then valleys
and lastly the coast by late morning or early afternoon. Gusty
winds will also push out over the coastal waters but with this
first push they will be confined mainly to the waters off the
Ventura and Malibu coast.

Then the real crux of the event begins Thursday night with warning
level wind across the mountains (especially LA County, including
the Santa Monicas) and possibly some of the valleys. Typically
even with these stronger events, warning-level valley winds are
confined to the elevated areas like the Santa Susanna mountains
(Wiley Ridge area) so am not super confident in the watch there,
at least for the more populated areas. Advisory level winds also
possible across the foothills of the San Gabriel Valley but that's
still more than 24 hours away. And gusty northeast winds will
push out of Orange County towards Catalina Thursday night and
bring gusty winds to the island into Friday morning.

Winds expected to decrease Friday afternoon and all areas may drop
below advisory levels before sunset, but some pockets of advisory
level winds are possible again later Friday night into Saturday
morning which may require a small extension of the advisories in
certain areas, namely the LA mountains and the LA/Ventura valleys.

Temperatures will be on the mild side for this event as there is
some cold advection aloft. Daytime temps mostly 60s to lower 70s.
though some mid 70s by Fri/Sat as ridging aloft develops. In
areas without winds, like the Ojai Valley, Antelope Valley, and
interior SLO County, overnight temps will be quite cold, 20s and
30s.

.LONG TERM (SUN-WED)...25/153 PM.

Light offshore flow will continue through Monday while the ridge
aloft Sunday shifts east Sunday night and is replaced by a weak
trough Monday with essentially zero impact. Models coming into
better agreement for Tue/Wed showing another cold upper low
dropping into the Great Basin generating yet another moderate to
strong Santa Ana event. Most of the ECMWF ensembles show this with
potentially even stronger gradients and wind speeds than with the
event this week. Will see how models handle this going forward,
but very high confidence in this dry pattern likely extending well
into Dec with periods of offshore winds.

&&

.AVIATION...26/0724Z.

At 0445z at KLAX... The inversion was surface based. The top of
the inversion was around 250 feet with a temperature of about 14
degrees Celsius.

Overall... Moderate to high confidence in the current TAFs. There
is a seventy five percent chance that LIFR/IFR conditions will
return to KLAX and KLGB 10z-17z, and a thirty percent chance at
the other coastal sites and KPRB. Otherwise and elsewhere, VFR
conditions will prevail.

KLAX... Moderate confidence in the current TAF. There is a
seventy five percent chance that LIFR/IFR conditions will return
10z-14z. Otherwise, VFR conditions will prevail throughout the
forecast period. There will not be any east winds greater than 8
kts.

KBUR... High confidence in the current TAF. VFR conditions will
prevail throughout the forecast period.

&&

.MARINE...25/609 PM.

Across the outer waters...A Gale Warning issued for the
northernmost zone, due to gusts over 40 knots observed there.
Otherwise, Small Craft Advisory (SCA) level conditions will
prevail through late Thursday night across all of the outer waters.
There is also a 50% chance of SCA level NE winds for the southern
waters on Friday. Conditions will be below SCA level Friday night
through Sunday, then there will be a 40%-50% chance of SCA wind
gusts at times on Monday.

Across the nearshore waters off the Central Coast...SCA level
winds will continue through early Thursday morning, and large
swell above 10 feet will affect the area tonight through Thu
evening. Winds and seas should then be below SCA levels late
Thursday night through Monday.

Across the inner waters south of Point Conception... Gusty NE
winds to SCA levels will develop Thursday night and persist into
Fri morning, with a 50% chance of Gale Force wind gusts at times
S of Ventura out to near Santa Catalina Island for Thursday night.
Short period, steep wind waves are expected to develop as well.
These hazardous conditions will affect Catalina Island, including
Avalon Harbor. Otherwise, conditions will be below SCA levels
through Monday.

&&

.BEACHES...25/559 PM.

A long-period northwest swell will bring high surf to beaches
along the Central Coast through Thanksgiving Day. The surf will
peak tonight through Thursday morning at 12 to 15 feet with local
sets to 18 feet along west to northwest facing beaches. Strong
rip currents are likely and beach erosion is possible. Minor
coastal flooding around the time of high tides will be possible.

Most of the swell energy will avoid the southern California
bight. Beaches south of Point Conception will have elevated surf
and a high risk of rip currents through Thanksgiving Day, but a
high surf advisory will not be needed for this area.

&&

.FIRE WEATHER...25/638 PM.

Red Flag Warnings now in effect for most of L.A. County and all of
Ventura County, from 2pm Thursday through 6pm Friday evening.

Moderate to locally strong Santa Ana winds will develop through
the day on Thursday, peak Thursday evening through Friday morning,
then gradually weaken into Saturday but stay locally breezy
through the weekend. Wind gusts between 40 and 65 mph are expected
over much of Los Angeles and Ventura Counties during the peak.
Meanwhile, humidities will increase tonight into Thursday morning,
then lower sharply Thursday afternoon and evening to 12 to 25
percent, lowering further to 5 to 15 percent for Friday through
Sunday. As a result, Red Flag conditions are expected to form
over much of Los Angeles and Ventura Counties by Thursday afternoon
or evening when the wind and drier air start to coincide, then
continue through Friday afternoon. There is a 50 percent chance
for low-end Red Flag criteria to be met Friday night through
Saturday or Sunday over the mountains and windiest valleys,
including the Santa Clarita and Ventura Valleys. There is a
growing potential for moderate Santa Ana winds and Red Flag
conditions over Los Angeles and Ventura Counties sometime Tuesday
through Thursday.

We are urging the public to be extremely cautious with anything
that can start a fire. Some ignition sources are obvious
(campfires, welding equipment, cigarettes, fireworks) but others
are less so (lawn trimmers, dragging trailer chains, firearms).
Those living in wildland interfaces and areas vulnerable to
wildfire should have a plan and be ready to evacuate if a fire
starts. Any wildfire that starts has the potential to spread
rapidly and exhibit extreme fire behavior due to the combination
of very dry fuels, low humidity, and strong gusty winds.
