Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
222 PM PST Sun Dec 26 2021

.SYNOPSIS...26/216 PM.

More rain and mountain snow will affect the area later tonight
through Monday evening, and again later Tuesday night thru
Thursday evening. Significant amounts of rain and snow can be
expected with these storm systems. There may be a few lingering
showers into Friday, then dry weather can be expected over the New
Years Day weekend. Temperatures will be significantly below
normal through the period.

&&

.SHORT TERM (TDY-WED)...26/210 PM.

Mostly sunny skies with just a few cu here and there covered the
region early this afternoon and this trend should continue thru
sunset. Temps this afternoon will be well below normal again,
about 6-12 deg lower than seasonal norms. Highs over the coast and
vlys will only be in the 50s to near 60, except 40s across the
Antelope Vly. Breezy W-NW winds should affect the region thru the
afternoon, altho should be quite gusty across the Antelope Vly.

A broad upper level trof with fast cyclonic flow aloft will
continue along the W coast at least through Tue, with a couple
more weather systems embedded in the upper level flow expected to
move into SW CA during the period. The first system, with a
vigorous cold front, will approach the area later tonight then
pass quickly thru the area Monday into Mon evening, bringing rain
and mountain snow to all areas. Gusty SW-W winds will also
accompany the front, with strong and gusty winds possible in the
mtns as 850 mb winds increase to 40-50 knots. Rainfall amounts for
this system will likely range from a about 0.25-1.00 inch for
most of the area with locally higher amounts in the mtns. It will
be another cold day on Mon with high temps remaining in the 50s
for the coast and vlys.

This will be a cold system with snow levels generally between
4000 and 5000 feet for most of the event. There is a chance of
slightly lower snow levels into Mon evening which would affect the
major mtn passes such as the Grapevine on Interstate 5. A Winter
Storm Warning will be issued with the afternoon zones for the
SBA/VTA/LA mtns for most of Mon into Mon night. There is the
potential for 5 to 10 inches of snow above about 4500 to 5000 feet
along with wind gusts up to 50 mph or even higher. Hazardous
wintry driving conditions can be expected with snow covered roads,
and very poor visibilities in snow and blowing snow.

Min temps have to be watched Tue night if skies clear out quickly
enough. There will likely be plenty of freezing temperatures in
the vlys and even in some interior coastal sections.

The second weather system will be a dry inside slider upper level
trof over eastern CA on Tue. A mostly NW flow aloft will prevail
over the forecast area, with mostly sunny to partly cloudy skies
overall. There may also be some light showers in far NW SLO County
in the afternoon. Temps will fall about 5 degrees from Monday due
to plenty of cold air advection. Highs will only be lower to mid
50s for the coast and vlys, except only in the 40s for the
interior vlys. These temps are about 15-20 degrees below normal
for late December, and could be close to record low max temps for
some areas.

It looks like an upper level low pressure area is going to develop
off the Oregon coast Tue night then track quickly S off the
northern and central CA coast on Wed. A surface low is expected to
develop off the Monterey County coast on Wed as well, with a
frontal system moving into swrn CA bringing more periods of rain
to the area starting Tuesday night and continuing at least thru
Wed evening. Early estimates of rainfall from this weather system
for Tue night thru Wed evening is generally in the 0.33-1.00 inch
range for most areas. There will also be low snow levels
generally between about 3500 and 5000 feet with significant snow
accumulations possible above about 4500 feet. There may be the
need for another Winter Storm Watch for the mtns as we draw
closer to the event. Gusty S winds will also accompany this storm
system thru Wed. Needless to say, temps will continue to be much
below normal across the forecast area on Wed.

.LONG TERM (THU-SUN)...26/205 PM.

The GFS and EC deterministic and mean ensembles are in generally
good agreement during the extended period. It looks like the
upper level low will continue tracking S to a position well SW of
the forecast area Wed night and Thu, then push E Thu night and
Fri and moving inland while weakening over nrn Baja by late Fri.
An inside slider will pass thru eastern CA Fri night then well E
into Sat, with a broad NW and dry flow aloft over srn CA for New
Years Day. A zonal flow aloft or even weak upper level ridging can
be expected for next Sunday.

The storm system that began Wed will continue to affect the
region late Wed night thru Thu evening, with additional
significant rain and mountain snow possible. The models do show
winds switching around to a NE direction over the area Wed night
and Thu which may lessen potential rain and snow amounts at that
time. A lot depends on the exact timing and position of the upper
level and surface low off the coast as a little nudge toward or
away from the coast could make a large difference in the storm's
impact. So overall, even though the models are in better
agreement, there is still only moderate confidence in the fcst for
this storm.

There may be a few leftover showers later Thu night and Fri as the
inside slider moves past the region. Dry north to northeast
offshore flow with mostly clear skies should then prevail over
the region New Years day thru Sun. Temps across the region will
remain significantly below normal thru the extended period.

.AVIATION...26/1822Z.

At 18Z at KLAX, there was no marine layer nor an inversion.

Low to moderate confidence in TAFs. Timing of rain start/end
times could be off by +/- 2 hours. Frequent cat changes from VFR-
MVFR can be expected during period of rain. There is a slight
chance that vis could drop to IFR conditions during periods of
heavier rain.

KLAX...Low to moderate confidence in TAF. Timing of rain
start/end times could be off by +/- 2 hours. Frequent cat changes
from VFR- MVFR can be expected during period of rain. There is a
slight chance that vis could drop to 1-3SM conditions during
periods of heavier rain. There is a 30% chance that east wind
component will reach 10 kt from 14Z-18Z, otherwise moderate
confidence in east wind component being 8 kt or less.

KBUR...Moderate confidence in TAF. Timing of rain start/end times
could be off by +/- 2 hours.

&&

.MARINE...26/221 PM.

In the outer waters, Small Craft Advisory (SCA) levels seas will
likely continue through Mon afternoon, however, there is a 30%
chance that seas will drop below advisory levels late tonight
early Mon morning. After a lull in the winds tonight, SW winds are
expected to increase late tonight, and will probably reach SCA
levels in most areas Mon morning. Winds will shift to W-NW and
increase Mon afternoon, reaching Gale force Mon afternoon thru
late Mon night. There is a 20% chance that winds do not reach Gale
force Mon afternoon/night for the waters north of Pt Sal. SCA
level winds will likely continue in some areas Tue morning, then
winds and seas will be below SCA levels thru Wed. SCA level E
winds are likely to reach SCA levels Thu, especially across the
southern two zones.

In the inner waters north of Pt Sal, seas have dropped below SCA
levels, though may be close to advisory levels toward the outer
portion of the zone. There is a 30% chance of SCA level SW winds
Mon morning, then Gale force NW winds Mon afternoon/evening. There
is a 20% chance that winds do not reach Gales Mon
afternoon/evening. SCA level winds may continue thru late Mon
night. SCA conds are not expected Tue thru Thu.

In the SBA Channel and the inner waters S of Pt. Mugu, winds were
at SCA levels, strongest in the western portion of the zones.
There may be a brief drop below advisory level, but likely not
long enough to cancel SCA. Gale force NW winds from mid afternoon
Mon thru late Mon night are likely. SCA level winds may continue
thru early Tue morning, then SCA conds are not expected thru Wed
night. There is a 30% chance of SCA level E winds Thu.

An unsettled weather pattern will bring periods of rain and
mountain snow to the region Wednesday into Friday. The rain will
create slick roads and travel delays along with moderate snow
accumulations and wintry driving conditions in the mountains.
