Synopsis 20 526 am.

Temperatures will trend warmer through midweek with many valley
locations in the mid to upper 90s, while the antelope valley
climbs back into triple digit heat Wednesday and Thursday.

Temperatures will cool slightly on Friday, then a modest warming
trend this weekend. Night through morning low clouds will remain
limited to coastal areas and the santa ynez valley each day
through Thursday then increase coverage again beginning this
weekend affecting coastal valleys.

Short term (tdy-thu) 20 253 am.

There is no eddy tonight and there are 1 to 2 mb offshore trends
in all directions. These two items have combined to eliminate the
marine layer stratus south of pt conception. Brisk NW flow has
brought stratus to all of the central coast and the santa ynez
vly.

It now seems almost certain that the mdl fcst given last weekend
is not going to pan out. Instead of a ridge or upper high, there
will be broad cyclonic flow albeit with fairly high hgts.

591 dm hgts and only weak onshore flow will combine today to bring
3 to 6 degrees of warming today to all areas except the beaches
which will see little change. The interior will be 3 to 6 degrees
warmer than usual... The vlys and the interior coastal sections
will be near normal, while the coastal areas nearer to the beaches
will still be several degrees blo normal.

It does not look like there is any mechanism to develop stratus
south of pt conception again tonight so looks for clear skies. The
central coast will still have plenty of stratus due to the NW flow
off of the waters. The bigger news tonight will be the sundowner.

The ksmx-ksba gradient will approach -4mb this evening and this
should bring about 35 to 45 mph gusts through and below the
passes and canyons of the santa ynez range. The strongest winds
will be west of goleta. A wind advisory has been issued for this
area starting at 6pm.

There is actually offshore flow from the north on Wednesday
morning. The hgts stay about the same. Still the low level air
mass will be warmer and MAX temps will climb a few more degrees.

There could be locally bigger warm ups in and around north
oriented canyons due to the morning offshore flow. At this time it
just looks like a warmer than normal day, but there should not be
a need for any heat products.

There will be another sundowner focused on gaviota it will flirt
with minimal advisory levels.

Hgts fall and onshore flow increases on Thursday. There may be a
few patches of stratus south of pt conception. MAX temps will slip
a bit but for the most part will remain above normal.

Long term (fri-mon) 20 304 am.

Fairly ambiguous weak upper level flow will be over southern ca
as all of the major features will be to the north west and east of
the area. Hgts will remain near 591 dm through the period. The
forecast dilemma resides in the low level flow. The GFS brings
back moderate onshore flow for the period, which would bring low
clouds back along with a cooling trend. The ec, on the other hand,
has weak onshore and even some weak offshore flow during the
period. The ec solution would be sunnier and warmer. The ec
struggles with sfc pressure and given the patter feel the GFS is
the way to go.

At one time there looked as if the remnants of a tropical system
could affect the area but both the ec and GFS no longer see this
threat.

Aviation 20 1058z.

At 08z at klax, the marine layer was 900 ft deep. The top of the
inversion was around 1300 ft with a temp of 24c.

High confidence in ksba, kbur, kvny, kpmd and kwjf tafs.

Otherwise..

N of point concepton... Moderate confidence with ifr cigs. There is
a 30% chance for lifr CIGS at kprb after 11z. Scour out times
should be + - 1 hour this morning, with similar timing expected
for CIGS to redevelop this evening.

S of point conception... Moderate confidence forVFR conds for
coastal TAF sites. There is a 30% chance for ifr MVFR CIGS to
develop at klax and koxr after 12z. Low confidence that any cigs
across coastal TAF sites will develop.

Klax... Moderate confidence in 12z taf. There is a 30% chance for
ifr MVFR CIGS to develop between 12-16z. Low clouds will be patchy
in nature. There will be a 50% chance of MVFR CIGS after 11z wed
morning. Good confidence in no east wind component over 3 kt.

Kbur... High confidence in cavu 12z taf. Confidence in taf.

Marine 20 246 am.

Outer waters... Moderate to high confidence in current forecast.

Small craft advisory (sca) level winds are expected to continue
through at least early Wednesday afternoon. There is a 30% chance
that winds will briefly drop below SCA levels late tonight and
wed morning. There is a 50% chance for gale force winds to develop
across the outer waters including areas NW of san nicolas island
from Wednesday afternoon through early Thursday morning. Therefore
a gale watch has been issued and valid for that time. There is a
30% chance that winds will briefly drop below SCA levels late tue
night and Wed morning.

Inner waters north of pt sal... Fair confidence in forecast with a
60% chance of SCA level winds during the afternoon and evening
today and Wednesday and a 40-50% chance on Thursday.

For the inner waters south of point conception... Good confidence
in forecast. There is a 60% chance for SCA level NW to N winds
across the western portions of the sba channel late this afternoon
through late tonight and once again during the same times
Wednesday. Not expecting sundowner winds on Thursday.

Lox watches warnings advisories
Ca... Wind advisory in effect from 6 pm this evening to 3 am pdt
Wednesday for zones 39-52. (see laxnpwlox).

Pz... Small craft advisory in effect from 3 pm this afternoon to 3
am pdt Wednesday for zones 645-650. (see laxmwwlox).

Small craft advisory in effect until 3 pm pdt Wednesday for
zones 670-673-676. (see laxmwwlox).

Gale watch in effect from Wednesday afternoon through late
Wednesday night for zones 670-673-676. (see laxmwwlox).

Hazard potential outlook (thu-mon)
Hot temperatures could lead to heat advisories for some inland
areas Thursday. The remnants of a tropical system could move north
into the region and bring chances for shower and thunderstorm
activity early next week. Strong rip currents and elevated surf is
also possible area area beaches.
