Synopsis 22 454 pm.

A high should build in through Thursday for fair skies with the
temperatures around the daily record maximums and above normal at
night. The onshore flow will return to start the cooling trend on
Friday. The temperatures will stay above normal on Friday and into
the weekend with the marine layer to bring in the overnight clouds.

Short term (tonight-wed) 22 758 pm.

***update***
northerly pressure gradients increased sharply early this evening
over sba county with the sba-smx gradient down to -4.1 mb at 02z.

Gusty NW to N winds developed through and below the passes and
canyons of S sba county including the santa ynez range, with some
gusts to around 40 mph noted at gaviota and refugio raws sites.

The support for advisory level winds will persist overnight in
this area, and have issued a wind advisory which will be in effect
until 3 am pdt late tonight. Gusty NW winds will also prevail in
the l.A vtu county mtns especially along the i-5 corridor for a
while tonight, with gusty W to SW winds in the antelope vly,
close to advisory levels at times.

The marine inversion was near 1300 ft deep at vbg early this
evening, and was near 500 ft deep at lax. Marine layer clouds
were noted along the central coast this evening but were
diminishing from the n. The low clouds should redevelop overnight
and affect mainly the immediate central coast later tonight. Low
clouds are expected to be sparse S of point conception overnight.

Otherwise, mostly clear skies with just a few hi clouds at times
can be expected thru the night across the forecast area.

***from previous discussion***
forecast remains largely intact through next weekend. The heat
wave has begun but will really kick into gear Monday and Tuesday
with plenty of triple digit highs. Still not expecting this event
to come close to the numbers with the heat wave earlier in the
month but still close to or locally exceeding record levels. Main
action today was to convert the excessive heat watch for northern
areas to a heat advisory. The primary reason for not going with a
warning up there is mainly due to the overnight lows recovering
into the 50s and lower 60s as opposed to the 70s in many areas in
the south. More impactful sundowners can be expected Mon tue
nights which will be hotter, drier, stronger, and more widespread
than tonight.

The rest of the forecast pretty much unchanged. Decreased stratus
coverage tonight south of pt conception given the minimal coverage
this morning and stronger northerly flow tonight. Still could be
some dense fog north of pt conception. Also bumped up highs a
degree or two based on most of the guidance trending in this
direction and the increase in forecast northerly gradients.

Long term (thu-sun) 22 1244 pm.

Gradients will start trending onshore Thursday which will begin a
slow cooling trend going into next weekend. Temps will still be
well above normal through at least Friday but 5-10 degrees cooler
than earlier in the week. At this point not expecting heat
advisories warnings after Thursday but could be a close call for
and advisory in some areas Friday. Monsoon moisture start to
increase across the area late Saturday into Sunday with the first
possibility for convection being on Sunday afternoon. May also
start to see some marine layer clouds returning to coastal areas
south of pt conception by next weekend.

Aviation 22 2351z.

At 2307z at klax, the marine inversion was around 800 ft deep. The
top of the inversion was around 1800 feet with a temperature near
27 degrees celsius.

Moderate confidence overall in the 00z tafs at ksbp and ksmx due to
the timing and extent of low clouds tonight into Mon morning. Low
clouds with lifr ifr CIGS are expected to move into these airfields
generally from 04z at ksmx to 08z at ksbp. The low clouds are
forecast to dissipate about mid Mon morning withVFR conditions the
rest of the day. The timing of the onset and dissipation of the low
clouds may be off + - one to two hours.

Elsewhere, generally hi confidence in the 00z tafs with mostlyVFR
conditions expected thru Mon afternoon, except a few low clouds with
MVFR vsbys due to fog will be possible at koxr, ksmo, klax and klgb
late tonight and early Mon morning. There is also a 30% chance low
clouds with ifr MVFR CIGS could affect klax and klgb at times late
tonight thru mid Mon morning.

Klax... Generally hi confidence in the 00z taf. There should be
mostlyVFR conditions thru Mon evening, except a few low clouds with
MVFR vsbys due to fog will be possible from about 11z-17z mon
morning. There is also a 30% chance low clouds with ifr MVFR cigs
could affect the airfield at times late tonight thru mid Mon morning.

Kbur... Hi confidence in the 00z TAF withVFR conditions expected
thru Mon afternoon.

Marine 22 808 pm.

For the outer waters... A gale warning has been added for the
southern two zones for Monday afternoon and Monday night. There is
a decent chance that this warning may need to be extended or
reissued for Tuesday and Tuesday night. For the northern outer
waters, a small craft advisory was added for late Monday morning
through late Tuesday. There is a good chance that this advisory
will be extended.

For the inner waters north of point conception... SCA conditions
will become more likely during the afternoon and evening hours of
Monday through Thursday. A small craft advisory has been added for
late Monday morning through late Monday night. There is a good
chance that this advisory will be extended or reissued.

For the inner waters south of point conception... SCA level winds
will continue through Monday night across the santa barbara
channel, especially western portions. Winds could drop off
briefly early Monday morning, but winds will increase again by the
afternoon. There is a 40 percent chance of SCA level winds
developing each afternoon and evening through Wednesday, again
mostly in western sections. For the western portion of inner
waters south of point mugu, winds will likely drop off late
tonight. There is a 40 percent chance of small craft advisory
conditions again on Monday afternoon and evening.

Beaches 22 1120 am.

A long-period southerly swell will be moving through the coastal
waters producing strong rip currents and high surf conditions at
southern california beaches Monday through Wednesday.
