.SYNOPSIS...11/323 AM.

Another warm day is on tap for today with temperatures above
seasonal normals, then a cooling trend will establish over the
weekend and into early next week as onshore flow strengthens.
Night through morning low clouds will become a staple of the
forecast over the weekend, pushing into the valleys by early next
week and into coastal slopes by mid week.

.SHORT TERM (TDY-SUN)...11/432 AM.

Another warm day is in the forecast today, but a cooling trend
will establish. Most of the cooling will take place for the
Central Coast, but a slight tick down in temperatures will occur
today for most areas. While a degree or two of cooling will be on
tap for the Southland, daytime temperatures will still well above
seasonal normals for today. Onshore flow will strengthen this
afternoon and bring more significant cooling on Saturday. A
cooler air mass will likely be in place through the weekend.

Low clouds and fog continue to kept at bay this morning, but some
low clouds are creeping northward along the South Coast of
California. Patchy low clouds and fog could fill in later this
morning across the Southland coastal areas as an eddy is progged
to form shortly after sunrise this morning. To the north, a fresh
stratus deck is pushing down the Central Coast of California and
low clouds and fog should start to spread into the Central Coast
beaches as the morning progresses. Patches of low clouds and fog
cannot be entirely ruled out again for the Santa Ynez River valley
this morning. The forecast leans more heavily on night through
morning low clouds and fog over the weekend as NAM BUFR time
height sections indicate a more pronounced marine influence due
to much stronger onshore flow. The marine layer induced low clouds
should become more expansive and extensive through the weekend,
with some beaches possibly struggling to clear on Sunday.

Outside of the marine layer and across the interior, temperatures
will likely remain above normal into early next week. Increasing
high cloudiness will make for a partly cloudy day and evening
across the area today, but periods of high clouds will stream over
the area as broad troughing become entrenched along the West
Coast over the weekend.

.LONG TERM (MON-THU)...11/612 AM.

A much cooler week is looking to shape up for next week as a
split flow pattern develop. A series of cutoff troughs of low
pressure will move over the region. Due to the uncertainty of the
movement of the troughs in the split flow pattern, there is large
spread of solutions across the medium range ensemble members, but
confidence is higher for cooler temperatures than the last several
days. Climatology favors cut off troughs affecting southern
California this time of year, and these troughs will likely make
for a tough time for forecasting the smaller details of the
pattern. While the first of the series should affect the region
early in the week, the forecast leans toward cooler temperatures
and a deep marine layer, but night through morning drizzle or
mountain showers cannot be ruled out in the pattern. A few
ensemble members have precipitation developing between Monday and
Tuesday, but pattern recognition of the deterministic solutions of
the GFS would introduce the possibility of mountain showers and
maybe isolated thunderstorms over the mountains during the
afternoon and evening.

As we get into the latter part of next week, cluster analysis
favor another cutoff trough moving over the southern California
region, potentially a stronger trough that could bring a chance of
showers to the region. A cooler air mass should be expected with a
mix of clouds and sun. Both GEFS and EPS ensemble members bring
the lowest 500 mb height means for the latter portion of next
week, which should equate to much cooler temperatures and trend
toward an unstable air mass. GFS solutions currently indicate a
559-561 dam trough moving over the Southland for latter half of
next week, climatologically strong enough to produce rain for
KLAX. Forecast values go with NBM solutions for now.

.AVIATION...11/1259Z.

At 12Z at KLAX, the marine layer was around 600 feet deep. The
top of the inversion was near 3200 ft with a temp of 22 C.

Low clouds and fog were confined to southern portions of the L.A.
County Coast early this morning, with LIFR to VLIFR conds. Cigs
should dissipate by mid morning, then VFR conds are expected thru
this evening. Areas of low clouds and fog with IFR to LIFR conds
are expected in most coastal areas of L.A./VTU Counties late
tonight, with a small chance of stratus on the Central Coast.
Conds should be mostly IFR tonight.

KLAX...Fairly high confidence in the 12Z TAF. There is a 10%
chance of IFR cigs from 15Z-17Z this morning. There is a 20%
chance skies will stay clear tonight. Any east wind component
should remain below 7 kt thru the pd.

KBUR...High confidence in the 12Z TAF with VFR conds thru the pd.

.MARINE...11/553 AM.

In the outer waters, GALE force winds in far western portion of the
northern zone (PZZ670) will become widespread in that zone this
morning, then spread into the central zone (PZZ673) this afternoon.
Gale force winds will continue in these areas much of the time thru
Sat evening. Small Craft Advisory (SCA) level winds are expected
late Sat evening thru Sun morning, then SCA level seas will
continue into Sun evening. In the southern zone (PZZ676), SCA
level winds will continue thru Sun morning, with seas likely
staying at SCA levels thru the evening. There is a 30% chance of
Gale force wind gusts during the afternoon/eve hours today/Sat.

In the inner waters N of Pt Conception, SCA level winds will likely
develop (>80% chance) this afternoon. SCA conds will likely
continue thru late Sat eve. Winds may drop below SCA levels late
tonight/Sat morning, but seas will likely remain near or above
SCA levels thru late Sat night. SCA conds are not expected Sun
thru Tue night. There is a 30% chance of Gale force winds during
the afternoon/eve hours today and Sat.

In the Santa Barbara Channel, SCA level winds are likely (70%
chance) in western portions during the afternoon/eve hours today
and Sat, with a 20% chance of SCA winds pushing eastern portions.
SCA conds are not expected Sun thru Tue night.

In the southern inner waters, there is a 20% chance of SCA level
wind gusts during the afternoon/eve hours today and Sat from
Anacapa Island to Malibu. Otherwise, SCA conds are not expected
thru Tue night.
