AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
1118 PM PDT Thu Apr 13 2017

.SYNOPSIS...
Tonight through Friday morning will be breezy with north to
northwest winds and the mountains may see a few lingering light
showers. Friday and Saturday will be several degrees warmer with
light offshore flow. Sunday through Tuesday will bring another set
of storm systems with a chance of some precipitation to the area,
mainly Santa Barbara and San Luis Obispo counties.

&&

.SHORT TERM...(TDY-SAT)

There were some lingering stratocu early this evening over the L.A.
County mtns, Antelope Vly and SBA County mtns. Otherwise mostly
clear skies prevailed across the region which should continue
overnight for most areas. Some upslope clouds and a slight chance of
showers can be expected overnight on the n mtn slopes, especially
for VTU County. Northerly gradients have been increasing this
evening, with -4.7 mb LAX-SFO and -3.2 mb SBA-SMX at 02Z. This
combined with some cold air advection at 850 mb, 850 mb winds up to
35 kt, and 950 mb winds 20-30 kt will help to bring gusty advisory
level nw to n winds tonight into Fri morning to the mtns of
SBA/VTU/L.A. Counties, SBA County s coast, Santa Clarita Vly, and
Antelope Vly. Gusts up to 50 mph can be expected in the mtns, with
gusts up to 40 to 45 mph elsewhere. A wind advisory is in effect for
these areas thru 9 AM Fri. Please see the latest Non-Precipitation
Weather Message for further details. There will also be gusty sub-
advisory nw to n winds overnight into Fri morning for the Central
Coast, some of the vlys adjacent to the coast, and Santa Monica
Mtns.

Broad but weak upper troffiness will linger over srn CA tonight.
Weak upper level ridging should then build into the area Fri thru
Sat. The upper ridging will weaken Sat night. For Sun, an upper trof
will move into the nrn CA coast, with the tail end of a surface cold
front brushing western SLO/SBA Counties.

Mostly clear skies with a warming trend will prevail across
southwestern CA Fri thru Sat. An eddy should develop Sat night with
some low clouds moving into the L.A./VTU County coastal areas.
Otherwise, some increasing clouds will prevail across the region
thru Sun, especially over SLO/SBA Counties. The weakening cold front
on Sun afternoon should bring a slight chance to chance of rain to
western and central SLO/SBA Counties as well.

Some gusty nw winds will be possible along coastal areas Fri
afternoon and early evening. Offshore flow can be expected Fri night
into Sat morning, with gusty sub-advisory nw to n winds possible in
the favored locations across the mtns, vlys and SBA County s coast.

Temps across the area are forecast to be near normal to slightly
below normal on Fri, warm to near normal to several degrees above
normal Sat, then cool to near normal to slightly below normal
overall for Sun, with the most cooling over SLO/SBA Counties. Highs
in the warmest vlys and inland coastal areas should reach the low to
mid 70s Fri, the mid 70s to near 80 on Sat, and low to mid 70s on
Sun.

***FROM PREVIOUS DISCUSSION***

.LONG TERM...(SUN-WED)

Overall, 12Z models still are indicating some significant
differences, making for a low confidence forecast through the
period. Both models agree that cold front passing across the area
Sunday night and Monday morning will be weak, generating some
light rainfall across the area (with the best chances across San
Luis Obispo and Santa Barbara counties).

Big differences exist for Monday night and Tuesday. Both the GFS
and ECMWF indicate another frontal passage, but differ
dramatically on the rainfall potential. The GFS is rather wet,
dumping over one half inch across San Luis Obispo and Santa
Barbara counties and one quarter inch or less across Ventura and
Los Angeles counties. Conversely, the ECMWF is MUCH drier,
indicating little precipitation. The models have been consistent
with these differences the last few days, keeping the forecast
confidence low. With the afternoon forecast, will continue to
split the difference between the models, indicating chance and
slight chance pops through Tuesday night. Hopefully, models will
converge on a solution over the next few runs.

For Wednesday/Thursday, models come back to some decent synoptic
agreement as a dry northwesterly flow pattern develops. With this
pattern, there is the potential for another round of advisory
level northerly winds.

&&

.AVIATION...14/0600Z

At 0545Z, there was no marine inversion present at KLAX.

Hi confidence in CAVU conditions for all TAF sites over the next
24 hours. Lower confidence on timing and strength of north wind
forecasts.

KLAX...High confidence in CAVU conditions through Friday. Lower
confidence in wind forecast with a 30 percent chc that north winds
will not develop of be weaker than fcst.

KBUR...High confidence in CAVU TAF.

&&

.MARINE...13/800 PM

High confidence in northwest winds at/above SCA for much of the
waters overnight. It is likely that there will be local gale force
gusts in the waters around the Channel Islands...with a 30
percent chance of these gusts becoming widespread enough to
warrant a gale warning. Winds will diminish some Friday morning
and increase again Friday afternoon into Friday night. There will
be a 40 percent chance of gales over the outer waters during this
time...especially the waters near Point Conception and southward
to San Nicolas Island. While weaker winds are expected on
Saturday...there is a 30 percent chance that SCA conditions will
continue into early Sunday across the Outer Waters.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
CA...Wind Advisory in effect until 9 AM PDT Friday for zones
      39-52>54-59-88. (See LAXNPWLOX).
