.SYNOPSIS...10/311 AM.

There will be above normal temperatures today. A cooling trend
will develop Friday and continue through the weekend. Night
through morning low clouds and fog will increase in coverage over
the weekend.

&&

.SHORT TERM (TDY-SAT)...10/252 AM.

The marine layer is under 1000 ft. There is offshore flow from the
north and 3 mb of onshore flow to the east. Marine layer stratus
covers the Central Coast but is largely absent from areas south
of Pt Conception. Ample sunshine, limited marine layer and 594 dam
hgts (3 dam above normal) will bring 2 to 5 locally 7 degrees of
warming to most areas. Max temps at the beaches will be in the
70s, coastal areas away from the beaches will be in the 80s and
lower 90s while the vlys cook up to 90 to 103 degrees. Triple
digit heat will dominate the lower mtn elevations and far
interior. This max temps are 5 to 10 degrees above normal. Not
quite hot enough for heat advisories, but still people working or
playing outside should be mindful of the heat.

One more round of advisory level Sundowner winds is expected to
redevelop later this afternoon and last into the overnight hours.

The onshore push to the east will be about 2 mb stronger on Friday
while the offshore flow from the north will flip to about 2 mb
onshore. This will bring more marine layer clouds to the coasts
and portions of the lower vlys. The cool marine air will have a
dramatic effect on the max temps which will drop by 5 to 10
degrees across all csts/vlys and most of the mtns. The Antelope
Vly and Cuyama vlys will only see very limited cooling since they
are so removed from the ocean. A 9 mb onshore push to the east
will bring gusty west to southwest winds are expected for
interior areas.

The onshore push to the north will be even stronger on Saturday
while the push to the east remains strong. There will be more
marine layer stratus in the vlys and some west facing beaches may
see only limited clearing. Another 3 to 6 degrees of cooling will
result in below normal temps for most of the area. Max temps will
end up in the upper 60s and 70s across the csts and 80s and lower
90s in the vlys.

.LONG TERM (SUN-WED)...10/309 AM.

A very static pattern develops for the xtnd period with high
pressure and 590 dam hgts. Very strong (9-10 mb) onshore flow to
the east will develop each afternoon. Every day will be very
similar to each other with night through morning low clouds and
patchy fog (isolated dense fog is possible). There will be good
clearing for most areas, but some beaches will likely remain
cloudy through the afternoon. The strong onshore flow will bring
gusty likely advisory level winds some of the mtns and the western
portions of the Antelope Vly and foothills. Below normal temps
will continue for most of the area although the Antelope Vly with
the downsloping westerly winds will remain 2 to 3 degrees above
normal. Max temps will remain in the upper 60s and 70s across the
csts and 80s and lower 90s in the vlys.

The gusty winds across the mtns and interior along with fairly
warm temperatures and fairly low humidities will bring an uptick
in fire weather danger.

The monsoon threat looks pretty non existent through Wednesday.
Some mdls hint at an increase in moist easterly flow starting next
Thursday or Friday.

.AVIATION...10/0601Z.

At 05Z, there was no marine layer at KLAX. There was a surface
based inversion, and the top of the inversion was near 2900 feet
with a max temperature of 28 C.

High confidence in KPMD, KWJF, KBUR, and KVNY.

Moderate confidence elsewhere with a 20-40% chance of IFR or lower
cigs/vsbys for KPRB and KSBA and south, highest for KOXR and
KCMA. There is a 40% chance that VFR conds prevail for KSBP.

KLAX...Moderate confidence in TAF. There is a 20% chance of
OVC003-OVC006 cigs and vsbys 1SM to 2SM from 10Z-16Z. High
confidence in any east wind component remaining under 8 kts.

KBUR...High confidence in TAF.

&&

.MARINE...10/1258 AM.

Small Craft Advisory (SCA) level winds will continue across the
outer waters south of Point Conception through early Friday
morning. There is a low- to-moderate (20-30 percent) chance of
Gale Force winds through Thursday evening from near Point
Conception south to San Nicolas Island.

SCA level winds are likely for the inner waters north of Point
Sal and the Santa Barbara Channel this afternoon and evening.
Local SCA wind gusts may occur this evening off the coast of Los
Angeles and Orange Counties, particularly across the San Pedro
Channel and near Point Dume during the aforementioned time. Steep
and choppy seas are likely across most of the coastal waters
through tonight.

Patchy dense fog focused across the waters adjacent to the central
coast and west of the Channel Island will likely continue through
this morning.
