Synopsis 13 658 pm.

Offshore flow beneath high pressure aloft will keep a dry weather
pattern in place through the end of the week. Onshore flow will
establish over the weekend as a trough of low pressure approaches
the california coast. A return of the low clouds and fog could
occur as soon as Friday at the coast.

Short term (tue-fri) 13 811 pm.

Latest satellite imagery indicated plenty of high clouds moving
across the region this evening, and the fog product was picking up
on the heat from the hot spot of the woolsey fire across the most
western portion of the santa monica mtns. Expect periods of high
clouds over the next few days.

Offshore winds were continuing across the wind prone passes and
canyons of l.A. And ventura counties early this evening. The lax-
dag gradient actually bumped up from -5.5mb at 5 pm to -6.3 mb a
couple hours later. The results have been a punch of very gusty
winds across the santa monica mtn range and the san gabriel mtns
this evening. Gusts in the upper 50s at boney mtn and camp 9, with
lower 50s across cheeseboro. Malibu hills was gusting to the mid
40s. With the gradients actually strengthening this evening, have
decided to extend the wind advisory for the l.A. And ventura
county mtns including the santa monica range through tomorrow
afternoon to coincide with the other valley wind advisories that
go through 3 pm tomorrow. The coastal sites are not expected to
reach wind advisory level criteria, although camarillo could could
gust to 35 mph briefly in the morning.

Expect the offshore flow to continue through Thursday morning,
before turning weakly onshore in the afternoon. Some beach cities
should see a late afternoon seabreeze tomorrow. With weaker winds
and less of a cold air source from the high desert to tap into,
high temps should moderate a few degrees warmer, especially
across the l.A ventura coast and coastal valleys. Highs should
reach the lower 80s, while interior locations will remain in the
upper 60s to around 70 degrees Wednesday. The central coast will
also see a few degrees of warming with continued offshore flow
from the san lucia mtns.

For Thursday, there will be weak offshore flow in the morning
before turning onshore. High temps will be cooler along coastal
areas due to the earlier sea-breeze and maybe a degree or two
cooler across the valleys. Interior locations such as the lower
mountain elevations and the antelope valley will warm a few
degrees. Gradients finally turn onshore Friday and the NAM is
showing a significant increase in boundary layer moisture from la
county south, suggesting that could be our first day of marine
layer stratus in a while. Highs will be a few degrees cooler,
mostly in the 70s.

Long term (sat-tue) 13 118 pm.

Cooling trend that begins in earnest Friday will continue into the
weekend with a return to onshore flow and likely a more widespread
marine layer for coast and eventually the lower valleys. Highs
mostly 60s to lower 70s so finally dropping to near to slightly
below seasonal norms.

As it was yesterday the situation for next week has been
complicated by inconsistent model solutions, though for the 12z
run today there was 100% agreement that any rain chances for this
area would hold off until at least Wednesday as the first upper
low that approaches the west coast actually slides well south into
mexico. This includes all the ensemble members and the nbm. So
have opted to keep rain out of the 7 day forecast. Confidence
doesn't really improve much after next Tuesday other than odds
favor at least some rain coming mid to late next week or the
following weekend but models are still all over the place. It will
probably be a few days at least before we gain any sort of
confidence in our rain chances for next week.

Aviation 14 0532z.

At 0530z at klax, there was no marine inversion.

High confidence in the 06z tafs.VFR conditions will prevail
throughout the 24-hour forecast period. High clouds will prevail
across the region through tonight.

Klax... High confidence in the 06z taf.VFR conditions will
prevail throughout the 30-hour forecast period.

Kbur... High confidence in the 06z taf.VFR conditions will
prevail throughout the forecast period. There is also a 20% chance
of llws at times between 08z-15z

Marine 13 147 pm.

For the outer waters... Generally hi confidence in the current
forecast. There is a 50% chance of small craft advisory (sca)
level NE to E wind gusts to 25 knots through early this afternoon
in the southern outer waters. Otherwise and elsewhere, the winds
will remain below SCA levels through Saturday.

For the inner waters north of point conception... Generally hi
confidence in the current forecast. Conditions are expected to
remain below SCA levels through Saturday.

For the inner waters south of point conception... Generally hi
confidence in the current forecast. There is a 60% chance of sca
level NE wind gusts through early this afternoon, especially near
shore south of rincon point and below passes and canyons. These
winds could affect the waters out to catalina island at times
until early afternoon, where there may be hazardous swells and
gusty winds in and around avalon harbor. Otherwise and elsewhere,
the winds will remain below SCA levels through Saturday.

Fire weather 13 110 pm.

Moderate santa ana winds combined with single digit humidities
will continue to bring very critical fire weather conditions
across much of los angeles and ventura counties through Wednesday.

The exception will be for the los angeles and ventura county
coasts, and the san gabriel valley where winds will not be as
strong and even a brief seabreeze across the oxnard plain this
afternoon. For the other valleys and mountains, northeast winds
gusting between 35 and 45 mph will decrease to 25 to 35 mph this
evening, then return again late tonight into Wednesday morning.

Winds will slowly decrease Wednesday afternoon with peak gusts in
the 20 to 30 mph range. These offshore winds in combination with
persistent single digit humidities will continue to bring red flag
warning conditions through 5 pm Wednesday for the ventura county
valleys, the los angeles county mountains, santa monica mountains,
santa clarita valley, and san fernando valley. Lax- daggett
gradient peaked at -7.1 mb this morning, and is expected to be
near -5.5 mb Wednesday morning, then -5.1 mb Thursday morning. A
light offshore wind influence will maintain dry conditions across
interior sections Thursday into Friday morning, maintaining
elevated fire weather conditions.

Fire weather conditions through santa barbara and san luis obispo
counties will be elevated through this period with plenty of dry air
along with pockets of gusty east winds expected.

If fire ignition occurs, conditions will be favorable for very rapid fire
spread and extreme fire behavior including long range spotting,
especially today into Tuesday.
