Synopsis 16 501 am.

An upper level high will keep temperatures above normal today.

Then on Thursday, a low pressure trough will cool temperatures
several degrees. Gusty northerly flow will develop Thursday
through early next week, especially across santa barbara los
angeles counties.

Short term (tdy-fri) 16 244 am.

Today will be a transition day between Tuesday's ridge and
Thursday's trof. Gradients are weakly offshore but still enough to
keep the low clouds away everywhere save for the central coast.

Skies will be partly cloudy as a plume of high level clouds waft
over the state. The offshore flow will bring a few degrees of
warming to most of vta and la counties but decreasing hgts in
ahead of the approaching trof will cause a little cooling over the
central coast.

A trof will begin to move through the state Wednesday night.

There will be an increase in the low clouds. Strong NW flow across
the outer waters will flow over the western sba coast through the
western passes and canyons of the santa ynez range creating a
weak sundowner mainly west of the airport. These northerly winds
will keep the sba south coast cloud free.

The trof should be east of la county by mid day. Skies will be
partly and at times mostly cloudy due to the mid and high level
clouds associated with the trof. Moderate onshore flow to the east
will develop while the N S gradient will stay weakly offshore. The
onshore push to the east is much more influential on most of the
areas temps. This onshore push, the 10 dm drop in hgts, the
increase in mid and high level clouds and the deeper marine layer
will all conspire to drop temps anywhere from 6 to 12 degrees.

Most MAX temps away from the beaches will be 3 to 6 degrees blo
normal. The passage of the trof will usher in an extended period
of windy conditions. Advisory level NW winds will develop in the
afternoon across the central coast and the antelope vly.

During the predawn hours Friday morning the lax-bfl gradient will
fall to -5.3 mb, the sba-smx gradient will fall to -3.1 and the
sba-bfl grad will fall to a fairly impressive -4.8 mb. Advisory
level winds will likely develop across all of the sba south coast
(more focused on the montecito area) and the i-5 corridor.

Advisory level gusts may also affect the santa clarita vly,
portions of the san fernando vly and the santa monica mtns. There
will not be much marine layer left probably just a little in the
long beach area. This north flow will also create plenty of
upslope clouds on the north slopes of the mtns on the kern county
line. Some of these clouds will likely spill over into the cuyama
vly.

A little warmer Friday due to sunnier skies, slightly higher hgts
and the increase in northerly offshore flow. The winds will also
turn a little to the northeast and there will be some santa ana
winds that will not reach advisory levels.

Long term (sat-tue) 16 316 am.

The long term forecast is all about the winds.

Gfs and ec and most of the ensembles agree that dry fast moving nw
flow will be over the state for the weekend and will move east
later Sunday as a warm upper high moves into the state from the
sw.

There will be moderate offshore gradient from the north and near
neutral gradients in the W E direction. It is likely that there
will be another round of advisory level sundowner winds Friday
night but sub advisory north winds through the i-5 corridor. Max
temps will be similar to Friday under sunny skies.

A very weak short wave will add a little oomph to the north flow
Saturday night. The lax-bfl gradient will fall to -7.3 mb, the
sba-smx gradient will fall to -3.8 and the sba-bfl grad will fall
to a very strong -6.7 mb. These gradients will produce at least
strong wind advisory level winds and there is a decent chc of
warning level gusts 60 to 65 mph through the tejon pass and
montecito hills. This will be the most critical wind day and will
be monitored closely. Better offshore flow develops from the east
as well and this will contribute to a 3 to 6 degree warm up across
the area. Most MAX temps will come in 3 to 6 degrees above normal.

On Monday the north flow relaxes while the east flow increases.

This will set up a santa ana event. There is no upper or thermal
support for the santa ana so it will likely not even be a moderate
wind event. It will be a warm event, however, as 590 dm hgts
combine with the offshore flow to bring another 4 to 8 degrees of
warming. Almost all of the coasts and vlys will have MAX temps in
the mid 80s to lower 90s. MAX temps will be 10 to 20 degrees above
normal.

Not much change Tuesday. Maybe a little cooling along the coast
due to an earlier sea breeze.

Aviation 16 1200z.

At 1124z at klax, the marine layer was 700 feet deep. The top of
the inversion was near 1500 feet with a temperature of 27 c.

Good confidence in all 12z tafs except for ksmx and ksbp where
there is much less confidence in timing and cig hgts. For areas s
of point conception, low confidence for timing of stratus tonight
into Thu morning. Moderate confidence with ifr to low MVFR cigs
when CIGS do develop. There is a 20% chance that CIGS will develop
across l.A and ventura counties and 30-40% forVFR conds at ksba.

Klax... Good confidence in 12z taf. Any east wind component will
remain less than 8 knots.

Kbur... .Good confidence in 12z taf.

Marine 16 213 am.

Outer waters... Moderate confidence for small craft advisory (sca)
level gusts this morning across the outer waters S of point sal
increasing to higher confidence by this afternoon. There is a 40%
chance for SCA level gusts for the northern waters through mid
morning, then higher confidence for SCA level gusts this afternoon.

Good confidence that SCA NW wind gusts and steep seas will continue
through Thursday mid afternoon. At that time, there will be a 60%
chance for gale force winds occurring by mid Thursday afternoon through
mid morning Friday. A gale watch has been issued valid from Thursday
mid afternoon through mid morning Friday for the entire outer waters.

After a brief decrease in winds Friday morning to SCA level gusts,
there is a 50% chance for another round of gale force winds by Friday
night or Saturday morning continuing into the weekend.

Inner waters N of point sal... Winds will remain below SCA levels
through early Thursday. Moderate to high confidence in winds increasing
to SCA level Thursday afternoon through Thursday evening. With a 20%
chance for local gale force winds Thursday evening.

For the inner waters south of point conception... Winds will remain
below SCA levels through early Thursday. Moderate to high confidence
in winds increasing to SCA level Thursday afternoon over the western
half of the santa barbara channel. There is a 30% chance for local
gale force gusts across the western portion Thursday evening. There
will be a 50% chance for SCA level gusts across the western portion
of the santa barbara channel both Fri and Sat late afternoon and
evening hours, then a 30-40% chance for Sunday afternoon and evening.

For the santa monica bay... There is a 50% chance for northerly sca
level gusts late Thursday evening through Friday mid morning.

There is a 20% chance for local gale force winds across the santa
monica bay between santa monica and the ventura county line from 4
am Friday through mid morning hours. Winds will then shift out of
the south nearshore east of malibu below SCA level thresholds by
late morning into the afternoon hours.

A long-period, large NW swell is expected to move into the waters
on Thursday and will likely persist through the weekend.

Lox watches warnings advisories
Ca... Dense fog advisory in effect until 9 am pdt this morning for
zones 34>36. (see laxnpwlox).

Pz... Small craft advisory in effect from 9 am this morning to 3 pm
pdt Thursday for zone 670. (see laxmwwlox).

Gale watch in effect from Thursday afternoon through Friday
morning for zones 670-673-676. (see laxmwwlox).

Small craft advisory in effect until 3 pm pdt Thursday for
zones 673-676. (see laxmwwlox).

Hazard potential outlook (fri-tue)
Moderate to strong northerly winds are expected through Sunday,
focused over santa barbara and los angeles counties. These winds
may produce damaging gusts near 60 mph Saturday night around the
santa ynez range. These winds and moderately dry conditions may
result in critical fire weather conditions in santa barbara
county. Gusty santa ana winds are possible Sunday afternoon
through Tuesday, with critical fire weather conditions possible
over los angeles and ventura counties.
