AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1026 AM PST Wed Nov 16 2016

.SYNOPSIS...
A trough will bring cool weather and increasing northwest to north
winds today. Gusty offshore winds will occur Thursday into Friday
with above normal high temperatures by Friday. Another low will
arrive on the Central Coast by Saturday for possible
precipitation that could spread to Los Angeles County by Monday.
Then a high will arrive Tuesday for a warming trend.

&&

.SHORT TERM...(TDY-FRI)

Satellite imagery this morning showing a narrow band of high
clouds pushing through the region, producing mostly cloudy
conditions for much of the area. Most areas should be partly
cloudy to mostly sunny later this afternoon, with the exception of
the north slopes and interior SLO county where a few sprinkles or
light showers are possible.

The narrow band of high clouds is associated with a moisture
starved trough. Behind the trough, northwest to north winds are
expected to increase this afternoon and this evening. At this
point, no changes are planned for the Wind Advisories. There was
some concern that a few areas may need to be upgraded to High Wind
Warnings. The 06z NAM came in stronger with the north winds, but
it appears the 12z fell back in line with what it was previously
showing. Regardless, it will be a strong Wind Advisory for areas
prone to north winds, with isolated gusts of 60+ mph in the
mountains.

A cool and dry airmass will also move in behind the trough. Frost
Advisories for interior areas remain on track for tonight. Same
for the Freeze/Hard Freeze Watches for tomorrow night. Overall
tomorrow night will be the coldest night this week.

***FROM PREVIOUS DISCUSSION***

Cooler and drier air moving in behind the trough will bring the
first frost to the interior valleys tonight and into Thursday
morning, where the winds will decouple tonight. Even colder
temperatures are forecast for the wind-sheltered areas on Thursday
night and into Friday morning when the driest air moves in.
Radiative cooling processes will be more efficient with clear
skies and some location in the Antelope Valley and the San Luis
Obispo Interior Valleys will likely see a freeze. The first frost
could impact the Ojai and Santa Ynez Valleys, as well on Thursday
night and Friday morning.

As colder air settles into the Great Basin tonight, surface high
pressure will develop. An inverted surface trough will develop
over relatively warmer Southern California and an offshore flow
regime, or Santa Ana weather pattern will take shape for Thursday
and Friday. The desert will be cool and dry, while the coast and
valleys will warm as compressional heating takes place.
Temperatures have been nudged a bit higher for Friday, likely the
warmest day for late week. Winds will likely continue across much
of Los Angeles and Ventura Counties into Friday morning. Wind
advisories will likely be needed for this time once the finer
details can be resolved in the model solutions.

.LONG TERM...(SAT-TUE)

Southwest flow aloft will start to develop on Friday and a change
of air masses will take place on Friday night and into Saturday.
A more pronounced cooling trend will develop through the weekend
and into next week ahead of an approaching trough of low pressure.
The trough, currently located near 45N and 167W will dip south and
approach the West Coast through Friday night or Saturday. From
there the models solution start to diverge. ECMWF solutions start
to deform, stretch and elongate the trough through the weekend,
while operational GFS solutions develop a cutoff trough off the
Southern California coast on Sunday night. High confidence exists
in a cooler and cloudier pattern for early next week, but low-to-
moderate confidence exists in the rain chances at this time. If
ECMWF solutions play out, certainly a more dry than wet pattern
will be in forecast, while the GFS solutions are much more
favorable for rain in Southern California.

A tip of the hat is given to the GFS as the ECMWF solutions seem
to be playing catch-up. A majority of GEFS members have a quarter
to an inch of QPF for KVBG between Sunday and Monday, and a
ensemble mean around 0.50 inch. Much more variance (0.00-1.50
inch) exists for KLAX, hence less confidence for areas south of
Point Conception. Enough confidence exists to have chance PoPs
for now, but GFS anomalies for mixing ratios and precipitable
favor staying on drier side as values are not impressive. In other
words, if we get rain, amounts may be on the near the mean of the
ensembles or less.

&&

.AVIATION...16/1800Z

At 1728Z, the depth of the marine layer was 1600 feet at KLAX.
The top of the inversion was at 3850 ft with a temperature of 16
deg C.

Good confidence in the 18z TAFS. Once the marine clouds clear in
the next couple of hours, VFR conditions are expected through
Thursday. The only other concern is very strong gusty winds and
low level wind shear as well as associated turbulence.

KLAX...Good confidence in the 18z TAF. After the marine clouds
clear in the next two hours, gusty winds and low level wind shear
will be the only concerns in the next 24 hours. North winds may
cause cross winds at the airfield after 06z.

KBUR...Good confidence in the 18Z TAF. 30 percent chance of LLWS
and lgt- mdt turbc aft 00Z.

&&

.MARINE...16/900 AM

Good confidence in gale warnings for the outer waters. Good
confidence in timing and strength of small craft advisories for
the inner waters. Gale force gusts are likely across the extreme
western portion of the Santa Barbara channel.

A large swell is expected to move into the waters today through
Thursday. Sea conditions will be choppy and hazardous across all
areas through Thursday due to the combination of building swell
and wind-driven seas.

.HAZARD POTENTIAL OUTLOOK...(FRI-TUE)
For Friday, gusty offshore winds are expected across mainly
Ventura and Los Angeles Counties bringing heightened fire weather
conditions and possible wind advisories.

Temperatures across the interior San Luis Obispo County Valleys
and Antelope Valley are expected fall to well below freezing late
Thursday night into Friday morning which could cause threats to
crops and pets or livestock.

A storm system could bring rain to the area Sunday through
Tuesday possibly causing wet roadways and minor localized
flooding.
