Synopsis 18 742 am.

High pressure aloft will build in over the region the next
several days. A warming and drying trend with gusty northerly
winds will develop through Thursday with temperatures warming to
above seasonal levels from Wednesday to Friday. A cool down is
likely Friday, becoming more pronounced over the weekend into next
week.

Short term (tdy-thu) 18 925 am.

Yesterday's system has moved east and a ridge of high pressure is
quickly establishing itself along the west coast. Everything looks
on track for a sundowner tonight followed by santa anas Wed thu.

The sundowner tonight may be strong enough for a low end wind
advisory as models have come in a touch stronger with the
gradients and winds aloft. The santa anas however still look quite
weak and well below advisory levels in most areas. Temps will be
warming up, peaking Thu before onshore flow returns.

***from previous discussion***
synoptically, a 590 dm upper high west of baja ca will begin to
nudge closer to southern cal over the next few days as the upper
low that brought light rain to the region will move into texas
today. The combination of the upper ridge building overhead, and a
northerly surface gradient setting up late this afternoon or
evening, will bring gusty sub-advisory northerly winds across the
i-5 corridor and likely spread south across santa clarita and san
fernando valley this evening. A sub-advisory sundowner will set up
as well this evening across the western portion of the sba south
coast, mainly between refugio and gaviota this evening. Winds
should begin to diminish across the sba south coast by midnight.

The northerly winds across l.A. County will begin to shift to the
northeast as a weak offshore gradient sets up between northern
nevada and so cal. At this time not expecting advisory level santa
ana winds Wednesday morning, but there could be a few local gusts
to 35 mph in the usual wind prone valleys of l.A. And ventura
counties, and between 40 and 45 mph for the mountains. Winds will
remain weakly offshore Wednesday into Thursday. Offshore winds
should remain fairly weak Thursday morning as there will be less
cold air advection from the high desert.

As for temperatures go, a warming trend is expected through
Thursday with high pressure building aloft and offshore flow
through the period, especially for coast and coastal valleys.

High temps will be around normal for most areas, while Wed thu
will be several degrees warmer. It will be slightly cooler across
the interior areas such as interior slo county and the antelope
valley. The central coast will see some additional warming due to
the offshore winds from the san lucia mtns. Except by Thursday,
the seabreeze should kick in earlier making it cooler than
wednesay. There will continue to be periods of high clouds over
the forecast area today and once again on Thursday. The warmest
temps across l.A. And ventura coast and valleys will be on
Thursday with some valley locations reaching the lower 80s, and
possibly a few coastal sites.

Long term (fri-mon) 18 254 am.

Both the GFS and ECMWF are in good agreement through Saturday
before becoming out of phase Sunday through Monday. On Friday, the
upper ridge will begin to breakdown as a weak upper trough moves
across california. Onshore flow will replace offshore flow from
Thursday. A cold front will fizzle out before it reaches the
northern portion of the forecast area Friday. Expect increasing
clouds and the start of a cooling trend. High temps will cool 3 to
8 degrees on Friday with highs still a few degrees above normal
across l.A. Ventura counties. Not much change for Saturday.

By Sunday the ec is advertising a weak upper disturbance moving
through the area, while the GFS has a weak ridge ahead of the next
upper trough. So GFS is showing a slight warming trend while the
ec is cooling slightly with a chance of rain. By Tuesday (xmas
day), the ec starts going in a different direction at that point
leading to low confidence as it's advertising a much deeper and
farther west upper low than the more "insider slider-ish" system
the GFS has. At the least there should be some cooling Tuesday
with cloudy conditions and a slight chance of showers. High temps
should be a bit cooler than normal for the time of year.

Aviation 18 1812z.

At 1800z... There was no marine inversion present at klax.

Generally hi confidence in the 18z tafs.VFR conditions can be
expected for the most part at the airfields through Wednesday,
except kprb where dense fog will develop again tonight.

Klax... Generally hi confidence in the 18z taf.VFR conditions are
expected thru the TAF period.

Kbur... Generally hi confidence in the 18z taf.VFR conditions are
expected thru the TAF period.

Marine 18 955 am.

Moderate to high confidence in the current forecast. A very large
wnw swell will continue to move through the coastal waters
through today. This swell will affect west to northwest facing
harbors, including morro bay, where dangerous breaking waves will
be possible in the harbor entrance. In addition, breaking waves
will be possible in shallower water areas outside the typical surf
zone. Moderate-to-high seas will then persist Wednesday through
Thursday.

Small craft advisory (sca) winds will affect the southern outer
waters zones (pzz673 and pzz676) through tonight or Wednesday.

Another round of SCA winds will be possible for the entire outer
waters Friday and Saturday, with a 50%-60% chance of this
occurring.

For the inner waters, winds are expected to remain below sca
levels through Saturday.

Beaches 18 959 am.

Surf heights will slowly subside the rest of today through mid
week before another large west northwest swell moves into the area
for later in the week. High surf advisories are likely to be
needed for several days.

The coastal flood advisory has expired. Water could locally spill
into normally dry beaches, beach parking lots and harbor
walkways. There is a risk of large breaking waves across the
morro bay harbor entrance, which could capsize small boats.

Some of this large swell energy has affected areas south of point
conception, impacting west-facing beaches of la, ventura, and
southern sba counties. High surf advisories remain in effect for
this area through 10 pm pst this evening, where west-facing
beaches will generally see 6 to 10 foot breakers, with the
highest surf for the ventura county coast. Local sets to 12 feet
will likely continue across ventura harbor as well. Surf of 5 to 8
feet is expected for the santa barbara south coast, highest on
beaches that have some west exposure, such as rincon point.

High surf could continue at least through Wednesday morning for
all areas.

Lox watches warnings advisories
Ca... High surf advisory in effect until 4 pm pst Thursday for
zones 34-35. (see laxcfwlox).
