Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
329 AM PST Tue Nov 23 2021

.SYNOPSIS...23/223 AM.

Fair weather today with cooling everywhere except for the
Antelope Valley. Another surge of gusty north winds will develop
early Wednesday in predawn hours. The winds will then transition
to a Santa Ana wind event later Wednesday through Friday. An
extended duration of very dry and warm weather will return through
the holiday weekend.

&&

.SHORT TERM (TDY-THU)...23/329 AM.

Skies are mostly clear this morning save for some mid level clouds
covering southern LA county. A decent sized vort max that at one
time looked like it might slide over LA county now will likely
pass to the south. Falling hgts and weaker offshore flow will
bring double digit cooling to the coasts. The vlys will end up 5
to 10 degrees cooler than ydy as well. Do to the lack of cool air
advection off of the high desert the Antelope Vly will buck the
cooling trend and warm about 5 degrees.

SFC high pressure will build into the center of the state this
evening and set up a sundowner and I-5 corridor wind event. The
gusts across the western portion of the SBA south coast may
approach advisory levels. Further south a weak eddy will likely
spin up a marine layer stratus deck that will cover portions of
the LA coast and some of the VTA coasts as well.

The low clouds should be short lived however as the SFC high
pressure shifts into the great basing and turns the gradients to
the NE. Sub advisory NE winds will develop over the Santa Lucias
while low end advisory level winds are likely along the
traditional Santa Ana line from the Santa Clarita Vly to western
Malibu coast. The strengthening SFC high over the Great Basin will
overwhelm the diurnal pressure pattern and the offshore flow will
increase through the day so there may not be much let up in the
winds during the afternoon. There will be a good deal of cold air
advection off of the high deserts and despite the compressional
warming most areas will cool. It is likely that only the beach
areas will see warming.

The cool dry air and long nights will combine to bring near
freezing conditions to portions of the interior SLO vly and a
possible hard freeze to the Antelope Vly early Thanksgiving
morning.

Wednesday evening a ridge will poke into the center of the state
while an upper low will set up in NW Mexico. This will bring NE
flow aloft over the area on Thanksgiving. At the same time the
offshore flow peak at around 8 mb from the east and 4 mb from the
north. The upper support and the strong offshore flow will combine
to bring a moderate Santa Ana wind event to the area. 45 to 55 mph
wind gusts will be common across eastern VTA county and western LA
county and isolated 60 mph gusts will occur on the windiest
ridgetops. The gradients will fall off in the afternoon and the
advisory level gusts will end early in the afternoon. The cool air
advection will sub side and max temps will rise 4 to 8 degrees
across the board. Most csts/vlys will see max temps in the upper
70s and lower 80s or about 10 degrees above normal. Along with the
winds will come very dry air with many areas of single digit
humidities. There are many fire weather concerns with this event
please see the fire weather section of the AFD for a detailed look
at the hazards.

.LONG TERM (FRI-MON)...23/328 AM.

Both the Deterministic runs of the EC and the GFS along with
almost all of their respective ensemble members keep the upper
ridge over the southern half of the state for the entire Friday
through the Monday period. High pressure over the Great Basin will
remain in place as well although it will weaken with time. There
will be offshore flow both from the east and north each morning.
By early next week however there should be a diurnally driven
return to onshore flow in the afternoon (esp to the east).

Friday will be the windiest day of the xtnd but the majority of
the ensemble members point to a sub advisory event. There will be
a few morning breezes each morning but nothing near advisory
levels.

Skies will be mostly clear through the period with maybe some
coastal stratus developing early next week over LA county.

Max temps will warm some each day Fri through Sunday with Sunday
being the warmest of the next 7. Sunday's max temps will be 13 to
15 degrees above normal. There will be noticeable cooling on
Monday as the offshore flow relaxes.

Unfortunately the ensemble crystal ball does not show any rain
through early December for Srn CA.

.AVIATION...23/0538Z.

At 0445Z at KLAX, there was no marine layer. There was a sfc based
inversion with a top of 500 feet with a temperature of 26 C.

High confidence in TAFs.

KLAX...High confidence in VFR TAF. No significant easterly wind
component is expected.

KBUR...High confidence in VFR TAF.

&&

.MARINE...22/857 PM.

For the outer waters, good confidence in forecast. Winds and seas
will remain below SCA levels through Tue morning. SCA level NW
winds are expected Tue afternoon thru Wed. There is a 20% chance
of Gale Force winds across the outer waters north of Point
Conception late Tue afternoon into Tue night. There is a 40%
chance of SCA level NW winds Thu thru Fri.

For the inner waters north of Pt. Sal, moderate confidence in the
forecast. SCA level NW winds are possible Tue afternoon and
evening. Otherwise, winds and seas will remain below SCA level
through the period.

For the inner waters south of Pt. Conception, moderate confidence
in the forecast. SCA level W to NW winds are possible across the
western SBA Channel late Tue afternoon into Tue night. There is a
chance of SCA level NE winds across the eastern SBA Channel and
southern inner waters Wed. By Wednesday night and Thursday, SCA
level NE winds are likely, creating hazardous choppy seas
nearshore from Ventura to Santa Monica, as well as the San Pedro
Channel. Due to increased cold air advection with this event,
there will be an increased risk of offshore winds extending
further out into the San Pedro Channel on Wednesday night and
Thursday morning, which could generate some 3 to 4 foot breakers
across northeast facing harbors including Avalon Harbor.

&&

.FIRE WEATHER...22/830 PM.

The next Santa Ana wind event remains on target. Winds will
increase on Wednesday, peak Wednesday afternoon through Thursday
morning, then gradually weaken through Saturday. Peak wind gusts
between 30 and 50 mph are expected, with isolated gusts to 60 mph
in favored mountain and foothill locations. Humidities will
drop to between 8 and 15 percent on Wednesday, then likely lower
into the 2 to 8 percent range by Thursday and Friday, which is
very dry, along with very poor overnight recoveries. High
temperatures will generally be in the 70s on Wednesday, and warm
to the mid 70s to mid 80s Thursday and Friday. As such, Red Flag
conditions are very likely for most of Los Angeles and Ventura
Counties Wednesday and Thanksgiving Thursday, with a chance of
continuing through Friday. The current Fire Weather Watches will
likely be upgraded to Red Flag Warnings by Tuesday. Elevated to
brief critical conditions will continue over Santa Barbara and San
Luis Obispo Counties, but the chance for Red Flags are minimal.

This is a critical period with multiple days of Red Flag
conditions. The public needs to be extra cautious with anything
that could start a fire. Those living near fire prone undeveloped
areas, like the national forests, should make or review the
family plan in the event of an evacuation order or a wildfire
start. This is especially important with unaware visitors during
the holiday week.

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...Fire Weather Watch in effect from Wednesday morning through
      Friday afternoon for zones

      Wednesday for zones 670-673. (See LAXMWWLOX).

&&

.HAZARD POTENTIAL OUTLOOK (THU-MON).

For Thanksgiving Day into Friday, very dry Santa Ana winds will
likely create critical fire weather conditions across Ventura and
Los Angeles Counties. Cold overnight temperatures in the interior
valleys could produce a frost or a freeze Thursday and Friday
nights.
