.SYNOPSIS...10/746 PM.

Above normal temperatures will continue on Friday. A cooling trend
will arrive Saturday and will continue through Tuesday.  Night
through morning low clouds are expected through the weekend and
into early next week. Below normal temps will work their way from
the beaches to the valleys Sunday through Tuesday while the
interior remains above normal. There will be a gradual increase in
night through morning low clouds and fog through Tuesday. Skies
otherwise, will be mostly clear.

&&

.SHORT TERM (THU-SUN)...10/759 PM.

***UPDATE***

Very nice day today. Skies were mostly sunny to partly cloudy as
some mid level clouds drifted overhead. South of Pt Conception.
These clouds lingered over VTA county and cooled the are 2 to 4
degrees. The Central Coast cooled as well as the onshore flow
there increase and brought a stronger and earlier sea breeze. All
max temps (save for the beaches) were above normal today with the
vlys and interior areas coming in 10 to 15 degrees above normal.

Friday will be sunnier which will bring some warming to most of
the areas. Onshore flow to the east increases some and this will
likely cool the beaches some.

Low clouds are developing near SAN county and will likely work
their way up to LA county just before dawn and last through mid
morning. There is a 30 percent chc that the low clouds will reach
VTA county as well.

Forecast is in good shape and will only need a minor update for
small adjustments to clouds and max temps.

***From Previous Discussion***

Weak northerly winds are expected tonight over the Santa Barbara
Southwest Coast and foothills, with gusts 25 to 30 mph. These
northerly winds are likely to increase during the evening to
overnight hours Friday into Saturday, possibly reaching advisory-
level speeds, especially Saturday.

On the large scale, there is a large ridge of high pressure
centered close to the 4-corners area, with 582 dm heights over SW
California. High temperatures will peak today, but very warm
conditions will persist into Friday with highs lowering only about
2 to 4 degrees.

The ridge aloft will continue to push eastward Friday into
Saturday as a trough of low pressure shifts toward the West Coast
and Pacific Northwest. Onshore flow will increase through the next
several days, helping enhance the cooling trend as heights aloft
decrease. However, while slight cooling is expected for most
areas on Friday, some portions of LA County could see a degree or
two of warming. Cooling on Saturday will be more pronounced
across the area, with highs down on average 5 to 10 degrees, and
as much as 12 degrees cooler in some locations. More extensive low
cloud coverage is expected Friday night into Saturday morning,
with a chance of further deepening (and cooling for coast and
coastal valleys) into Sunday.

.LONG TERM (MON-THU)...10/136 PM.

Fairly good agreement with the medium range models with cooler
conditions through much of next week, especially the first half of
the week. An elongated upper trough is forecast to split with a
couple of cut off lows forming, one near Point Conception and the
other to the southwest near 140 W and 30 N. The weak low near
Point Conception will be dry with no precip chances, but the
offshore low is forecast to swing toward the coast late in the
period. Any precip is very low confidence at this time. However,
there is a chance of a deep marine layer forming with low clouds
moving well onshore through much of next week, with associated
areas of drizzle or light rain during the night to morning
periods.

.AVIATION...11/0006Z.

At 2330Z at KLAX, the marine layer was around 400 feet deep. The
top of the inversion was near 2200 ft with a temp of 24 C.

Moderate confidence in coastal TAFs with a 25 percent chc of no
cigs at sites with cigs and a 20 percent chc of LIFR cigs 11Z-17Z
at sites with no cigs fcst.

High confidence in inland TAFs.

KLAX...Moderate confidence in TAF 09Z-17Z with a 25 percent chc of
no low clouds. High confidence for the rest of the times. Good
confidence that any east wind component will be under 6 kt.

KBUR...High confidence in TAF.

.MARINE...10/809 PM.

In the outer waters, A GALE WARNING is in effect for the northern
zone (PZZ670) through late tonight for wind gusts up to 35 kts.
Otherwise, Small Craft Advisory (SCA) level winds (21+ kts) are
expected (>90% chance) to persist thru at least late Sat night or
early Sun morning across the outer waters. SCA level seas (10+
feet) will develop Fri afternoon/eve and will likely linger into
Sun afternoon. There is a 50-60% chance of GALE force winds in the
northern two zones (PZZ670/673) Fri afternoon thru Sat evening,
so a GALE WATCH has been issued. There is a 40-50% chance of GALES
in western portions of PZZ676 during aforementioned timeframe.
Will let the overnight shift assess whether or not an upgrade to
GALE warning is necessary.

In the nearshore waters N of Pt Conception, a combination of SCA
winds and seas are likely (>80% chance) thru late Sat, especially
in the afternoon and evening hours. SCA level seas could linger
thru late Sat night. There is a 30-40% chance of GALE force winds
during the afternoon/eve hours Fri and Sat.

In the Santa Barbara Channel, SCA level winds are likely (50-70%
chance) across western portions during the afternoon/eve hours Fri
and Sat, with a 20% chance of SCA winds pushing into eastern
portions.

In the southern inner waters, there is a 10-20% chance of SCA
level wind gusts during the afternoon/eve hours on Fri and Sat
around Anacapa Island. Otherwise, SCA conds are not expected thru
Sun.

Sub advisory conds expected Sun afternoon through Tues across the
entire coastal waters.
