Synopsis 17 135 pm.

Temperatures will be cooler this weekend then warmer next week
with the highest readings midweek. Overnight and morning low clouds
and fog will continue in coastal and adjacent valley areas through
Monday then will be primarily along the coast through Wednesday.

Short term (tdy-tue) 17 208 pm.

The marine inversion early this afternoon was near 2400 ft deep at
lax. Low clouds lingered along portions of the central coast and sba
county S coast into the afternoon, with patchy low clouds noted
along the vtu county coast. The marine layer stratus is expected to
linger along portions of the coast thru early evening, and perhaps
expand some inland over the coastal plain by sunset, otherwise
mostly sunny skies will prevail for the rest of the day.

Nam fcst gradients of +9.2 mb lax-dag are expected for late this
afternoon. The good onshore gradients will promote gusty S to w
winds across much of the foothills, mtns and deserts thru early
evening. Temps will be much cooler across the forecast area as well,
with highs expected to reach only into the 80s in the warmer vlys
and lower mtns, altho the antelope vly should still warm into the
90s this afternoon. Temps overall across the region today will be 6-
12 deg below normal for this time of year.

An upper level trof will persist along and off the ca coast thru
sun, with h5 heights in the 586-588 dm range. A large upper level
high over the southern plains will start to slowly expand W and into
srn ca Sun night thru tue, with h5 heights expected to increase to
590-591 dm for Mon afternoon and 592-594 dm for Tue afternoon. A dry
sw flow aloft will prevail for the most part thru the period.

The marine inversion is expected to be slightly lower tonight into
sun morning, then shrink to about 1500-1800 ft or so Sun night into
mon morning, and probably down to 1000-1500 ft for Mon night into
tue morning. Plenty of night and morning low clouds and fog will
affect the coastal areas into portions of the adjacent vlys thru
mon, then be confined mainly to the central coast, santa ynez vly
and the l.A. County coast Mon night into Tue morning. Low clouds and
fog will likely affect the salinas river vly as well for the late
night and morning hours tonight thru Tue morning. Otherwise,
mostly clear skies will continue across swrn ca thru tue
afternoon.

The onshore flow will slowly decrease thru the period, with the lax-
dag forecast gradient (nam) expected to be about +8.3 mb sun
afternoon, +7.3 mb Mon afternoon and +6.3 mb Tue afternoon. Some
gusty s-w afternoon and evening winds will continue for the
foothills, mtns and deserts especially thru Mon afternoon. Some
gusty NW winds are also forecast for the central coast during the
period.

Temps are expected to remain about 6-12 deg below normal for many
areas on sun, then warm slightly to about 2-7 deg below normal for
mon. On tue, temps will continue to warm up, with highs ranging
from slightly below normal along the coast to 2-8 deg above normal
inland. The warmest vlys and lower mtns should reach the 80s to
low 90s on sun, mid 80s to lower 90s mon, and 90s to around 100 on
tue.

Long term (wed-sat) 17 212 pm.

It looks like the upper ridging will split Wed and Thu with one
upper level high centered over the desert SW to four-corners region
and another upper level high centered over the E pac off the ca
coast. Between these upper level highs, weak upper level troffiness
will move into swrn ca, altho h5 heights will still be rather high
at around 588-591 dm. Weak upper level troffiness will linger over
the forecast area Fri before h5 heights increase again into Sat as
upper level ridging starts to move back in.

The marine inversion should lower to well below 1000 ft deep by
early Wed before deepening again Fri and Sat to above 1000 ft.

Marine layer night and morning clouds and fog should be confined
to just the central coast Tue night into Wed morning, with all the
low clouds remaining off the coast Wed night and Thu morning. The
nightly low clouds should then spread back into the coast and
some adjacent vlys from Thu night into Sat morning. Otherwise, a
dry air mass will keep skies mostly clear across the region thru
the extended period.

Temps are forecast to become quite hot again across the region wed
and thu, with highs about 4-12 deg above normal away from the
immediate coast. Only slight cooling is expected Fri and Sat as
temps remain a few degrees above normal away from the coastal plain.

The hottest temps during the extended period will be Wed and thu
with highs reaching the upper 90s to around 104 in the vlys and
lower mtns, and 103 to 106 in the antelope vly. These forecast high
temps may eventually prompt the issuance of heat advisories for some
of these areas.

Both the ec and GFS forecast the development of a tropical cyclone
off the southern mexico coast probably as early as tue, then the
models track this system NW to a position off the SRN baja coast by
fri or sat. This system has a good chance of becoming the 9th
named tropical cyclone for the eastern pac this season which would
be ivo. The moisture and swell from this system could affect swrn
ca during the last week in august.

Aviation 17 1720z.

At 1615z, the marine inversion at klax was based at 2700 feet.

The top of the inversion was 4500 feet with a temperature of
23 degrees celsius.

Overall, moderate confidence in 18z coastal valley tafs and high
confidence in desert tafs. Current MVFR CIGS will dissipate by
noon withVFR conditions for all sites this afternoon. For
tonight, high confidence in return of stratus fog to all coastal
and valley sites, but only moderate confidence in timing.

Klax... Overall, moderate confidence in 18z taf. High confidence in
vfr conditions this afternoon. For tonight, high confidence in
return of MVFR cigs, but only moderate confidence in timing (could
be + - 2 hours of current 04z forecast).

Kbur... Overall, moderate confidence in 18z taf. High confidence in
vfr conditions this afternoon. For tonight, high confidence in
return of stratus, but only moderate confidence in timing (could
be + - 2 hours of current 07z forecast). There is a 40% chance
of ifr CIGS 07z-12z.

Marine 17 151 pm.

For the outer waters, moderate to high confidence in current
forecast. High confidence in winds and seas remaining below small
craft advisory (sca) levels through Sunday. On Monday and Monday
night, there is a 50-60% chance of SCA level winds developing. For
Tuesday through Thursday, high confidence in SCA level winds.

For the inner waters north of point sal, moderate to high
confidence in current forecast. High confidence in winds and seas
remaining below SCA levels through Sunday. On Monday, there is a
40% chance of SCA level winds during the afternoon and evening
hours. For Tuesday through Thursday, there is a 70% chance of sca
level winds each afternoon and evening.

For the inner waters south of point conception, moderate to high
confidence in current forecast. Generally, high confidence in
winds and seas remaining below SCA through Thursday across a
majority of the area. The only exception will be the western half
of the santa barbara channel where there is a 60% chance of sca
level winds on Tuesday and Wednesday during the late afternoon and
evening hours.
