Synopsis 21 954 pm.

Gusty offshore winds will continue through Wednesday across many
mountain and valley areas and will be strongest during the morning
hours. Temperatures will gradually warm through the week as
conditions remain dry.

Short term (tdy-thu) 22 254 am.

Strong north flow aloft covers the state as a trof exits to the
east and a ridge pushes into the north of the state. At the sfc a
1038mb high sits over NRN nv. The kdag grad is almost 3mb offshore
while the kbfl grad is nearly 6mb offshore. The north flow has
banked up plenty of clouds across the NRN la mtns and slo sba vta
corner of SW kern county. The upper support and the strong sfc
grads will combine to bring advisory level winds to much of the
area south of pt conception today. Right now the strongest winds
are from the north and are affecting areas like the i-5 corridor
and the sba south coast. North winds are spill out of the passes
and canyons of the santa monica mountains bringing advisory level
winds to the malibu area and even traveling further south to bring
interesting cross winds to klax. Later this morning the winds
will shift a little to the NE and the vlys near the vta la county
line will see advisory level gusts.

Aside from the clouds near the kern county line skies will be
sunny today. MAX temps will warm some but there will be just
enough cool desert air moving into the area to keep MAX temps a
degree or two below normal.

On Wednesday the state will be under NW to SE flow around the east
side of pacific ridge. At the sfc the kdag grad will increase and
will be greater than the kbfl grad and this will create another
santa ana event. There will be advisory level wind gusts from the
la mtns through all the vlys on the la vta county line and then
through the santa monica and out through malibu. With no cool air
advection the compressional warming will take hold and most of the
coasts and vlys will see 4 to 8 degrees of warming, most cst vly
will end up 3 to 6 degrees above normal.

There is a little cyclonic bend in the NW flow on Thursday as a
large long way trof sets up over the eastern two thirds of the
nation. Offshore flow will weaken just enough to preclude advisory
level gusts but there will still be plenty of 15 to 25 mph gusts
in the morning in the areas favorable for NE winds. Everyone will
be talking about the MAX temps as almost all of the coasts and
vlys will be in the mid to upper 70s and there will likely be a
few 80 degree readings as well.

The combination of clear skies and very dry air will allow for
rapid nighttime cooling in the wind sheltered areas. There will be
a few areas of near or actual freezing temperatures across the
deserts and the interior vlys.

Long term (fri-mon) 22 314 am.

The ec and GFS agree that the right side of the east pac ridge
will move over the state on Friday. On Saturday the ridge will
move further east and the ridge axis will be right on the coast.

On Sunday the ridge axis will move further east and will run the
middle of the state. The mdls disagree on Monday with the gfs
keeping a weaker ridge over the area while the ec pushes the
western edge of a very large near CONUS spanning trof westward
into the state.

There will be a good uptick in the offshore flow both Friday and
Saturday and it looks like there will be advisory level santa ana
wind gusts each morning. Skies will remain clear and MAX temps
will continue to be 5 to 10 degrees above normal.

The offshore winds will be a little weak on Sunday but the hgts
will peak. Sunday will be 1 to 3 degrees warmer than Saturday and
will be the warmest day of the next 7.

Lower hgts and weaker offshore flow on Monday. There will either
be some cooling (gfs) or plenty of cooling.

Next Tuesday is a long way off but both the ec and GFS are
advertising a major offshore wind event.

Aviation 22 1035z.

At 1030z, there was no marine inversion at klax.

Overall, moderate to high confidence in 12z TAF package. High
confidence inVFR conditions for all sites through the TAF period.

However, moderate confidence in wind forecast due to uncertainty
of timing of changes in direction strength.

Klax... High confidence in 12z taf.VFR conditions are anticipated
through the TAF period. There is a 60% chance that northerly
cross winds will continues 12z-14z. There is a 30% chance of llws
12z-20z.

Kbur... High confidence in 12z taf.VFR conditions are anticipated
through the TAF period. Moderate confidence in north to northeast
winds gusting 20-25 knots 16z-23z. There is a 50% chance of llws
and strong uddfs.

Marine 22 235 am.

For the outer waters, high confidence in current forecast. Winds
and seas are expected to remain below small craft advisory (sca)
levels through Saturday. However, there will be some local gusts
to 25 knots this morning, especially around point conception.

For the inner waters north of point sal, high confidence in
current forecast. Winds and seas are expected to remain below sca
levels through Saturday.

For the inner waters south of point concpetion, moderate
confidence in current forecast. There is a 70% chance of SCA level
north to northeast winds today from ventura southward then a 50%
chance of SCA level northeast winds again late tonight and
Wednesday. Otherwise, winds and seas are expected to remain below
sca levels through Friday. On Saturday, there is a 50% chance of
sca level northeast winds developing again, from ventura
southward.

Beaches 22 235 am.

A westerly swell will produce moderate to elevated surf and
strong rip currents on west-facing beaches through this morning
and a beach hazards statement will remain in effect until noon
today. Large astronomical high tides are also be expected this
morning. Due to the higher than normal tides and the surf, there
could be minor coastal flooding near the time of the morning high
tide around 10 am this morning.

Lox watches warnings advisories
Ca... Beach hazards statement in effect until noon pst today for
zones 34-35-40-41-87. (see laxcfwlox).
