Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1042 PM PST Mon Dec 13 2021

.SYNOPSIS...13/153 PM.

A strong storm system will slowly move over the region through
Tuesday. Rain, heavy at times, and high elevation snow will
develop later today and will continue through Tuesday. Gusty and
potentially damaging winds are expected over the area through
Tuesday. Another weak storm system will affect the region Thursday
followed by dry weather next weekend.

&&

.SHORT TERM (MON-THU)...13/757 PM.

***UPDATE***

Rather cloudy and cool day today with highs mostly in the 50s. The
day was mostly dry save for SLO county coast and foothills where
is has been raining for most of the day.

The big storm is just beginning to transform from an atmospheric
river configuration to one of a more classic cold frontal set up.
This transformation is due to a strong jet diving down the
backside of the parent trof.

The front is over NW SLO county and has not moved much. As a
result there is a steep rainfall gradient across SLO county with
2.87 inches total over Rocky Butte (in the foothills north of
Cambria) to an inch in Morro Bay to just a quarter inch near the
SBA county border. Southerly flow ahead of the front has created
decent rainfall across the Santa Ynez range where about a half
inch has fallen which is much less than the tenth of an inch or so
across the flatter portion of southern SBA county. Pockets of
light rain have just begun to develop over portions of VTA and LA
county as well.

The 00Z NAM does not differ too much from the previous thinking.
There will be two rainfall peaks...one with the main front and
then a second with a jet enhanced post frontal trof. Peak rain
for SLO and western SBA county will occur now through sunrise.
Southern SBA county will have their peak rain from midnight to 300
am and another mid morning. VTA county will lag southern SBA
county by about 3 hours. LA county will have the first peak mid
morning and the second in the early afternoon. Flash Flood Watches
look good as both peaks will be capable of producing rainfall
rates at or slightly above established debris thresholds for the
recent burn areas.

Strong jet dynamics still look good for some convective/TSTM
development esp over LA county in the afternoon.

Rainfall and snowfall totals still look good. The new NAM does
move the main trof through the area quicker which will limit the
amount of lower elevation snow tomorrow evening- will evaluate
than and address it in the 300 am update.

***From Previous Discussion***

Overall, 12Z models in good synoptic agreement through the short
term period. Main features will be a strong upper low moving
across the area tonight/Tuesday, followed by a much weaker low
moving across the West Coast on Thursday.

Forecast-wise, main focus continues to be on a very strong storm,
moving across the area tonight and Tuesday. Overall, 12Z models
continue to advertise the same story, leading to a high confidence
forecast. Moderate/heavy rain (associated with a cold front) will
impact SLO/SBA this afternoon and tonight with the rain pushing
south and east tonight and Tuesday with moderate/heavy rain
across LA county on Tuesday. Behind the front, there will be some
lingering showers Tuesday night, mainly across the northern
slopes. Rainfall totals with this storm still look to range from
1-3 inches for coasts/valleys and 3-6 inches across the foothills
and mountains. Locally higher amounts will be possible in the more
favored upslope areas through Tuesday afternoon. Hourly rainfall
rates generally 0.33 to 0.66 per hour are expected with local
rates up to 1.00 per hour possible. With a strong jet moving
across the area on Tuesday, there will be a slight chance of
thunderstorms all areas during the day on Tuesday which could
enhance rainfall rates. Due to the potential for significant
rainfall and rainfall rates, a FLASH FLOOD WATCH has been issued
for burn scars in SBA and LA counties. Please see LAXFFALOX for
the latest details on timing/location.

With this system, snow levels will remain quite high through
Tuesday (above 6000 feet) as the heaviest rain moves through. So,
resort levels can expect anywhere from 1 to 3 feet of snowfall.
For lower elevations, snow levels will not drop until late Tuesday
afternoon/night when the rain will be tapering. So, snowfall
totals at lower elevations will be much less. However, there is a
possibility of 1-3 inches of snowfall Tuesday night down to the
Grapevine level. Please see LAXWSWLOX for the latest details on
WINTER STORM WARNINGs for the LA and Ventura mountains.

Finally, the third main hazard with this storm will be strong and
gusty winds. Gusty southerly wind will continue to increase
tonight and Tuesday across the area. Across the local mountains as
well as the interior valleys of SLO/SBA counties and Antelope
Valley, warning level wind gusts are likely and a HIGH WIND
WARNING remains in effect for these areas. Elsewhere, advisory
level wind gusts are likely and WIND ADVISORIES remain in effect
for all other areas. Please see LAXNPWLOX for the latest details
on the various wind products.

After a cool and dry Wednesday, another system is expected to
impact the area on Thursday. However, this system on Thursday is
much weaker than the current system. Initial rainfall estimates
with this system are for 0.25 inches or less with the "heaviest:
rainfall across the Central Coast.

.LONG TERM (FRI-MON)...13/150 PM.

For the extended, models exhibit good synoptic agreement through
the period. At upper levels, ridge will build in from the west
through the weekend. Near the surface, varying amounts of offshore
flow will develop.

Forecast-wise, this pattern will lead to dry conditions across the
area through the weekend. There may be some scattered high clouds
from time-to-time, but offshore flow will keep any stratus from
developing. So, mostly clear conditions can be expected. There
will be some gusty northeast winds through the period, but winds
are generally expected to remain below advisory levels. Despite
the ridge overhead and the offshore surface flow, temperatures,
albeit warmer, will still be a few degrees below seasonal normals.

.AVIATION...14/0635Z.

At 0450Z at KLAX, there was a deep moist layer to 7000 feet.

Low confidence in all TAFs as cigs, vis, wx and winds will all be
highly variable. Cigs and VIS will be predominantly MVFR. Only
isolated instances of LIFR conds are expected. There is a 20
percent of chance of thunderstorms Tuesday with the best chc over
the LA coast late morning through afternoon. Improving conditions
are likely after 02Z.

Turbulence is likely over and near to the higher trrn.

KLAX..Low confidence in all TAFs as cigs, vis, wx and winds will all be
highly variable. Cigs and VIS will be predominantly MVFR. There
is a 20 percent chc of brief 1SM +RA OVC004 14Z-18Z. There is a 20
percent of chance of a TSTM 18Z-00Z. There is a 30 percent chc
that the wind direction will be 140 degrees in the morning which
would dramatically increase the east wind component.

KBUR...Low confidence in all TAFs as cigs, vis, wx and winds will all be
highly variable. Cigs and VIS will be predominantly MVFR. There
is a 20 percent chc of brief 1SM +RA OVC004 14Z-18Z. Lgt turbc is
likely and there is a 30 percent chc of mdt turbc.

.MARINE...13/1049 AM.

For the Outer Waters, moderate confidence in current forecast.
Gusty winds will start out southerly, reaching Gale Force sometime
this morning over northern portions of the waters. Winds shift to
a northwest direction Tuesday afternoon and night. Gale force
winds should linger over southern portions of the outer waters
into Tuesday evening. The current Gale Warning has been extended
into Tuesday night for the waters south of the Channel Islands.
SCA level seas may linger into Thursday.

For the Inner Waters north of Point Sal, moderate confidence in
current forecast. High confidence in SCA level wind and seas
remaining through Tuesday, with Gale force winds likely today and
tonight. By Wednesday, high confidence in winds returning to below
SCA levels, whereas SCA level waves may linger into Thursday.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. High confidence in winds
increasing to SCA levels today and remaining through Tuesday.
Gale force winds are likely this evening through Tuesday evening.
By Thursday, high confidence in winds and seas returning to below
SCA levels.

A storm system approaching from the northwest will bring
dangerous sea conditions with widespread gale force winds, seas up
to 12 to 15 feet, and steep waves, especially along the Central
Coast. There will also be moderate to heavy rain and the
potential for thunderstorms. Refer to the Marine Weather Statement
for more information. Mariners should remain in safe harbor
during these dangerous conditions.
