Aviation discussion updated...

Synopsis 22 833 pm.

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

Short term (tdy-wed) 23 246 am.

Still a few gusts over the sba south coast but not enough to
continue the wind advisory. There is a 500 ft deep marine layer
but good offshore trends both from the north and the east have
prevented any stratus formation save for the sba county west
coast. Hgts will rise to about 595 dm and this along with the
offshore trends and sunny skies will combine to bring MAX up about
3 to 6 degrees from ydys readings. MAX temps today will mostly be
8 to 10 degrees above normal today. Excessive heat warning and
hear advisories all kick off today at 1000 am. These product will
continue through Thursday as a heat wave grips SRN ca.

There will be another advisory level sundowner tonight as well as
a sub advisory north wind push down the i-5 corridor. The
compressional warming created by the sundowner will likely make
the evening the warmer than the afternoon for many locations along
the sba south coast. There will be only a minimal marine layer
stratus presence tonight likely just around the western portion of
sba county as the north push eliminates the stratus elsewhere.

Heat will remain a problem even after sunset for the sba south
coast and all of vta and la counties. The warm airmass... Very
strong inversion and north winds will all combine to make overnight
lows in the upper 70s for many vly mtn desert areas as well as all
of the sba south coast. These kinds of lows are 12 to 18 degrees
above normal. The lack of good overnight cooling is actually the
major driver for the heat warning. Slo and the rest of sba
counties will have comfortable lows near 60 and these areas are
only under a heat advisory.

The high will continue its slow move to the west but Tue and wed.

Hgts will rise again Tuesday to about 598 dm and then change
little an Wednesday. The N to S gradient will go offshore flow
both Tue and Wed mornings with only a minimal return to onshore
flow in the afternoon. Tue and Wed will be nearly identical days
and will be the warmest days of the next 7 with MAX temps up
another 1 to 3 degrees from todays already very warm values. Again
there will be advisory level sundowner winds both Tue and wed
nights. Low temps will also continue to be well above normal south
of pt conception.

Long term (thu-sun) 23 314 am.

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 mid week will have to take a closer
look at Friday to determine if any heat products will be needed
for that day as well. Monsoon moisture will start to increase
across the area late Saturday into Sunday as the upper high
retreats eastward with the first possibility for convection being
on Sunday afternoon. Stratus will slowly reform across some
coastal areas starting Friday or Saturday as the onshore flow
strengthens and the hgts fall.

Aviation 23 1205z.

At 0833z at klax... The inversion was surface based. The top of
the inversion was around 2200 feet with a temperature of about 30
degrees celsius.

Overall... Moderate confidence in the current coastal tafs and
high confidence in the remaining tafs. There is a sixty percent
chance of lifr ifr conditions developing at ksbp near daybreak
and along with similar conditions at ksmx will remain only for a
few hours past daybreak. There is a ten percent chance of lifr ifr
conditions occurring at other coastal terminals during the 12z-
17z period. Otherwise and elsewhereVFR conditions will prevail.

Klax... Moderate confidence in the current taf. There is a ten
percent chance of lifr ifr conditions occurring during the 12z-
17z period. OtherwiseVFR conditions will prevail. No east winds
greater than 8 knots are expected during the forecast period.

Kbur... High confidence in the current taf.VFR conditions will
prevail throughout the forecast period.

Marine 23 304 am.

For the outer waters... A gale warning is in effect for the
southern two zones for this afternoon and tonight. 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 (sca) was added for late this
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
today through Thursday and an advisory has been added for late
this morning through late tonight. 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 tonight across the santa barbara channel,
especially western portions. Winds could drop off briefly early
this 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 there is a 40 percent chance of SCA conditions developing
this afternoon and evening.

Beaches 23 507 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 today through Wednesday.
