Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1100 PM PST Tue Dec 7 2021

updated aviation discussion

.SYNOPSIS...07/904 AM.

Dry and cool conditions expected the rest of today through
Wednesday. A better chance of rain and mountain snow will move
over the area with a stronger storm system between Wednesday night
and Thursday. A cool air mass is expected to linger into the
weekend, then a potentially significant storm system could affect
the area early next week.

&&

.SHORT TERM (TUE-FRI)...07/809 PM.

***UPDATE***

Latest satellite and surface observations indicate partly to
mostly cloudy skies across the area this evening, due to a
combination of low and high clouds. Current AMDAR soundings do not
indicate much, if any, marine inversion, but a deep moist layer
up to around 4000 feet. No significant winds are observed.

Forecast-wise for the immediate short-term, weather should remain
very benign overnight. With a deep moist layer, but not solid
inversion, low clouds coverage will be very chaotic overnight. So,
partly to mostly cloudy wording will cover the situation best.
Additionally, there could be some patchy fog across the area, but
like the low clouds, any fog development will be very chaotic. As
for winds, no issues are anticipated overnight.

Overall, current forecast has good handle on the immediate short
term. So, no significant updates are expected this evening.

***From Previous Discussion***

We've entered an active period of weather but there will be at
least a day or two of relative quiet between systems. The first of
those is now through Wednesday evening. Dry weather but cool with
mostly light winds and some clouds at times but also a fair amount
of sunshine. The next system on tap for Thursday, though precip
will likely begin before sunrise in many areas. Another light
event overall but slightly higher rainfall than today's rain. And
once again little to no southerly flow ahead of it so really no
precip enhancement potential. In these scenarios the transverse
ranges often provide a rain shadow to Ventura County so amounts
there will likely be a tenth or less. Elsewhere probably in the
tenth to quarter territory. Highest likely in northwest SLO County
and eastern San Gabriels where up to around a half inch is
possible. Minimal to no impacts with this one. Snow levels around
6000' for most of the precip portion of the event, with up to 3 or
4 inches possible at higher elevations. One potential issue to
watch for is some post-frontal colder air coming in Thursday
evening with northwest flow maybe generating some upslope showers
near our border with Kern County. At that time snow levels drop
to around 4500' so a dusting or a mix of rain and snow near the
Grapevine in the evening can't be ruled out.

The next "break" in the weather will be Thursday night into
Friday, though there will be some gusty winds during that time.
First from the northwest Thursday night and then shifting to
northeast Friday. Either or both of those events could be advisory
level, though more likely Thursday night. The northwest winds
will be focus in the mountains but could also sneak into southern
Santa Barbara County, especially in the Montecito Hills area. The
Friday winds will be of the Santa Ana variety and will focus on
the usual parts of Ventura and LA Counties. Probably a better
chance of advisory winds with the northwest event Thursday evening
but there could be some brief advisory level gusts Friday as
well. A little warmer on Friday but still mostly just low to mid
60s.

.LONG TERM (SAT-TUE)...07/159 PM.

A little bit of warming over the weekend with lighter winds to
continue to the overall quiet period. The next system, the
strongest of the bunch by far, will hit the northwest coast of SLO
County as early as Monday morning. Ensembles and deterministic
solutions in remarkably good agreement on timing and strength, and
run to run consistency has been very good as well so confidence is
higher than usual this far out. However, having said that, it's
not uncommon for storms that have strong southerly flow ahead of
it to slow down prior to arrival. In any case, timing
uncertainties aside, this has the ingredients for an impactful
storm, and one that has the potential to cause some flooding
issues beyond just the routine ponding of water. Not seeing a lot
of convective potential yet, but strong orthogonal flow hitting
the foothills and mountains should be enough to enhance rain rates
to levels we haven't seen in quite some time. The most likely
time frame for those higher rates appears to be on Tuesday when
the cold front comes through. Will have more details later as we
get closer but certainly rain totals in the 1-3" range seems like
a good early estimate. Quite possibly higher (3-5") in the usual
favored upslope areas like Rocky Butte in northwest SLO and in the
Santa Ynez Range. Snow levels around 7000', so a good dump for
the ski resorts but not much impact elsewhere through Tuesday.
Potentially at lower elevations Wednesday depending on how much
moisture is left behind the front.

&&

.AVIATION...08/0658Z.

At 0621Z at KLAX, the marine layer was at 3000 feet deep. The top
of the weak inversion was at 4000 feet at a temperature of 10 C.

Low confidence in TAFs. With a weak inversion in place low clouds
will likely be highly disorganized. There is a 50% chance of MVFR
conditions for LA and Ventura County coastal sites 09Z-18Z. Cig
heights will likely vary frequently.

KLAX...Low confidence in TAF. There is a 50% chance of BKN025
09Z-18Z. High confidence that any east wind component will stay
below 4 kt.

KBUR...Low to moderate confidence in TAF. There is a 30% chance
of BKN025 10Z-17Z.

&&

.MARINE...07/834 PM.

For the rest of tonight and through Wednesday afternoon, good
confidence that winds and seas will remain mellow and below SCA
level. However, a strong eddy circulation may bring SE wind gusts
of 10 to 15 kt through the San Pedro and Santa Barbara Channels
through Wednesday morning.

NW winds will strengthen again Wednesday night into early
Thursday morning across all the waters ahead of an approaching
storm. High confidence in at least SCA level conditions over all
the waters by mid to late Thursday morning lasting through at
least Friday morning. There is also moderate confidence (40%
chance) of Gales across the outer waters from the Central Coast to
San Nicolas Island developing by Thursday afternoon. Small Craft
Advisory level winds are likely across the inner waters. These
gusty winds will create dangerous short period seas over all the
waters. Seas just above 10 feet are likely across the outermost
waters, mainly on Thursday.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
PZ...Gale Watch in effect from Thursday afternoon through late
      Thursday night for zones 670-673-676. (See LAXMWWLOX).

&&

.HAZARD POTENTIAL OUTLOOK (FRI-TUE).

Lingering rain and snow showers are possible Thursday evening
near the Grapevine. Gusty northwest to northeast winds are
expected late Thursday into Friday. Gales are possible across the
coastal waters between Thursday and Friday. A potentially
significant storm system should move over the region between late
Monday into Tuesday.
