Synopsis
A trough over the western u.S. Will keep cool weather across the
region today. This trough will sharpen tonight and thu, bringing
lots of clouds, with a slight chance of showers to much of
ventura and los angeles counties. The trough will linger across
the region, keeping below normal temperatures into the beginning
of the weekend. An upper ridge building in from the west, and week
offshore flow will bring significant warming to the area Sunday
and Monday, with above normal temperatures continuing Tuesday.

Short term (tdy-fri)
low clouds were slow to form this morning, but were finally
starting to organize across eastern l.A. County. The marine layer
was deep, so clouds were approaching the coastal slopes. The big
question is far west the cloud shield will expand this morning. At
this point, feel that clouds overspread all l.A. County valleys,
and into at least eastern vtu county, with mostly clear skies
elsewhere, except for some patchy low clouds on the central coast
and in the santa ynez valley. The other tricky part of the
forecast will be the clearing of any low clouds. Based on the very
weak inversion, would expect clouds to clear reasonably well, but
there could be some stratocu development this afternoon near the
foothills. Gusty winds continued in the mountains, so will leave
marginal wind advisory in place through mid morning. Gusty west
winds will affect the antelope valley this afternoon with gusty
northwest winds on the central coast, but winds should remain
below advisory levels. It will be another cool day across the
region, with MAX temps 5 to 10 degrees below normal in most areas.

Broad upper trough across the western u.S. Will sharpen up and
dig southward tonight and Thu in response to a strong vort
dropping southward from the pac nw. The marine layer will deepen
and low clouds, which will in fact not be that low, will likely
push into all coastal and valley areas, up to the coastal slopes
tonight. With the strong vort rotating into the region on thu.

Models are showing some decent lift in the moist layer, especially
across l.A. And vtu counties, so there will be a slight chance of
showers or some light rain, especially in the foothills of eastern
l.A. County and on northern mountain slopes. Expect skies to
remain partly cloudy in the afternoon, except possibly remain
mostly cloudy across l.A. County. It will be breezy on the central
coast, in the antelope valley and in the mountains. MAX temps
will likely drop a few more degrees on thu, and will be 10 to 20
degrees below normal in many valley, mountain and desert
locations, and 5 to 10 degrees below normal across the coastal
plain. The exception could be across the south coast of sba
county, where some NW winds in the afternoon could bring some
downslope warming.

The upper low will evolve into a closed low over northern nevada
thu night, with a sharp trough lingering south southwestward into
the forecast area. The marine inversion may be eradicated, so not
too sure that there will be much in the way of low clouds, except
possibly across l.A. County. Otherwise, expect partly cloudy skies
thu night and fri. It will be another cool day on fri, though
temps may edge upward a few degrees.

Long term (sat-tue)
the upper low will be slow to move eastward Fri night and sat,
with a sharp trough axis hanging back over the region, especially
on the ec solution. Height rises (especially on the gfs), and
weakening onshore flow should bring some warming to most areas on
sat, though MAX temps should be below normal in most areas. There
may be some low clouds Fri night Sat morning, most likely across
coastal sections of l.A. County. The upper low will move eastward
sat night and sun, and both models show strong height rises across
the area. In addition, low level flow will turn offshore. This
should bring significant and widespread warming across the
forecast area, especially west of the mountains. MAX temps may
rise above 90 degrees in some of the warmer valley locations
Sunday.

The ec shows an upper high over the eastern pacific edging
eastward into the region Mon for continued height rises, as did
the 00z gfs. The 06z GFS shows a shortwave trough dropping south
southwestward through the great basin, and actually shows heights
lowering a bit. Both models show offshore flow continuing,
probably enough for some gusty, but below advisory level,
northeast winds. Will go with the ec and the 00z gfs, and
forecast a few more degrees of warming in most areas mon. Both
models show slight height rises for Tue as the upper ridge pushes
slowly eastward. There will likely be some additional warming in
the mtns and deserts, and possibly even west of the mountain if
the low level flow does not turn onshore.

Aviation 20 12z.

At 1130z at klax... The inversion was around 2700 feet deep. The
top of the inversion was around 6200 feet with a temperature of 24
degrees celsius.

Overall... Low to moderate confidence in the current tafs at
coastal and adjacent valley terminals and high confidence at
remaining terminals. Patchy stratus has developed over portions
of los angeles county including the coastal plain... The san
gabriel valley... And the far eastern section of the san fernando
valley as well as portions of santa barbara county. Ifr MVFR
conditions will waft in and out of klax... Klgb... Ksmo... And
ksmx through 17z. There is a fifteen percent chance of those
conditions reaching kvny and kbur during that time period as
well. Ifr MVFR conditions will return to most coastal and adjacent
valley terminals after 03z. Otherwise and elsewhereVFR
conditions will prevail. There is a slight chance of rain in
portions of los angeles county after 21 12z.

Klax... Moderate confidence in the current taf. Ifr MVFR
conditions will waft in and out through 17z then will return after
04z. OtherwiseVFR conditions will prevail. Southeast winds to 10
kts may develop 21 10z-14z. There is a slight chance of rain after
21 12z.

Kbur... Low to moderate confidence in the current taf. Patchy
stratus has developed in the terminal vicinity and there is a
fifteen percent chance of ifr MVFR conditions 13z-17z. Ifr MVFR
conditions will develop tonight after 04z. OtherwiseVFR
conditions will prevail.

Marine 20 200 am.

Winds across the outer waters...

winds are only locally reaching gale warning levels this morning
in the northern and central outer waters but will be stronger in
the afternoon and evening hours through Thursday afternoon. A
gale warning for the southern outer waters has been replaced with
a small craft advisory through early Thursday morning with a gale
watch issued from Thursday morning through Thursday afternoon.

Stronger winds across the outer coastal waters may continue into
Friday and the warnings and or advisories may need to be
extended.

Winds across the inner waters...

the northern inner waters will have small craft advisory (sca)
level winds through Thursday afternoon. Winds across the santa
barbara channel will be below SCA levels into early this afternoon
but may strengthen to SCA levels winds by late afternoon and
evening and possibly into each afternoon and evening through
Thursday night.

Hazardous seas...

combined seas will peak today at 7 to 9 feet at 14 seconds as
building short-period waves combine with the first northwest
swell of the season.

Lox watches warnings advisories
Ca... Wind advisory in effect until 10 am pdt this morning for
zones 53-54. (see laxnpwlox).

Pz... Small craft advisory in effect until 3 pm pdt Thursday for
zone 645. (see laxmwwlox).
