Synopsis 22 105 pm.

An upper level high pressure system combined with the weak
onshore winds will result in an extended period of very warm
temperatures this week.There is a slight chance of afternoon
thunderstorms over the ventura and los angeles county mountains
and deserts through Wednesday. Night through morning clouds will
return to some coastal areas, mainly north of point conception at
least through Wednesday.

Short term (tdy-thu) 22 230 pm.

The marine inversion had lowered to near 700 ft deep at lax early
this afternoon. Low clouds lingered along the immediate central
coast, with some low clouds also along portions of the sba county
s coast. These low clouds will probably persist thru late
afternoon. Otherwise, mid level clouds continued to move into the
forecast area from the S with sunny to partly cloudy skies
overall across the region.

There will be afternoon instability in the mtns and deserts (fcst
li's down to -2 to -4) and decent MUCAPE (200 to as much as 500
j kg) along with pwats of 1.00 to 1.50 inches moving into the area.

These ingredients will contribute to a slight chance showers and
thunderstorms over vtu l.A. County mtns and antelope vly this
afternoon into early this evening, especially for the vtu county
mtns and eastern san gabriel mtns and eastern antelope vly. If any
thunderstorms develop, they would be capable of producing brief
heavy rain, gusty winds, small hail, and dangerous cloud-to-ground
lightning.

Decent onshore gradients this afternoon (nam fcst lax-dag +9.0 mb at
00z) will help to bring locally gusty S to W winds to the foothills,
mtns and deserts this afternoon and early this evening as well.

Temps will be a few degrees warmer today, with highs reaching into
the 90s to near 100 in the warmest vlys and lower mtns. The antelope
vly is expected to heat up into the 100 to 103 degree range. These
temps will be near to slightly above normal overall.

A large four-corners upper level high pressure system will remain in
place through Wednesday. The center of the upper level high is then
expected to drift S along the az nm border Wed night and thu. The
western periphery of this upper level high will be over SRN ca thru
the period, with h5 heights in the 590-593 dm range over the
forecast area. The upper level flow will be out of the S and SE thru
thu, which will help to draw additional monsoonal moisture into the
area especially Tue and wed. Pwat values should be in the 1.00 to
1.50 inch range for the most part during the period. H850 dewpoints
are forecast to be in the 8-10 deg c range each day thru Wed then
drop to about 6 to 8 deg c on thu.

The marine inversion should increase to around 1200-1300 feet
deep tonight then lower to 700 feet or less Tue night thru thu.

Night and morning low clouds and fog are expected to linger along
the central coast tonight through Thu morning, and along the l.A.

County coast tonight into Tue morning and again Wed night into
thu morning. Otherwise, mid-level moisture with some cloudiness
will bring partly cloudy skies at times to the forecast area
through thu.

There will be enough moisture and instability on Tue for a slight
chance of afternoon and evening thunderstorms over the l.A vtu
county mtns and antelope vly. By wed, there will be a slight
chance of afternoon thunderstorms over the eastern san gabriel mtns.

There will be just an outside shot at an afternoon thunderstorm over
the eastern san gabriels Thu afternoon, but the chance of this is
less than 15 percent and is not reflected in the current forecast.

Onshore gradients will turn weaker Tue and wed, which should help
coastal areas warm up a bit. With slightly stronger onshore flow
thu, temps along the coast should drop slightly. Away from the
coast, temps will be several degrees above normal with temps in the
warmest vlys and lower mtns expected to reach the 90s to about 102
on tue, and mid 90s to 105 on wed, then drop back into the 90s for
the most part on thu. The combination of the daytime heat, warmer
nighttime lows, and somewhat higher humidities may prompt the
issuance of heat advisories by Wed for the vlys and mtns. Some
locations on Wed could even approach excessive heat warning
thresholds.

Long term (fri-mon) 22 232 pm.

The ec and GFS are in general agreement that the large upper level
hi will drift W on Fri then build into SRN ca on sat. The upper
level high should persist over the region Sun before drifting back
e into az for mon. H5 heights over swrn ca will peak around 596
dm on sun.

It looks like the deeper monsoonal moisture will be largely
shunted back to the E of the region during the extended period,
with no afternoon convection expected. The marine inversion will
remain very shallow thru the period, with some night and morning
low clouds and fog possible for the immediate central coast and
just along the l.A. County coast. There may also be some night
and morning low clouds and fog along the vtu county coast Fri thru
sat. There may be a few mid or hi level clouds at times over the
region as well, otherwise mostly clear skies should prevail for
the most part Fri thru mon.

Temps will remain several degrees above normal for most areas thru
the extended period. The warmest vlys and lower mtns are expected
to be in the mid 90s to 103 Fri thru sun, then cool a degree or
two for mon.

Aviation 22 1921z.

At 1741z at klax, the marine layer was 1100 feet deep. The top of
the inversion was near 3500 feet with a temperature of 27 c.

Low to moderate confidence in the 18z TAF package. The marine
layer depth was around 1000 feet across the entire coast. The
marine clouds have cleared from most coastal TAF sites, soVFR
conditions will continue until late this evening when the marine
clouds return to most locations with more ifr to lifr conditions.

There is some doubt concerning the return of marine clouds to the
south coast, but the current tafs included that possibility.

Klax... Low to moderate confidence in 18z taf. There is a 40
percent chance ofVFR conditions through the night. There is a 10
percent chance of a shower.

Kbur... Moderate confidence in 18z taf. There is a 10 percent
chance of a shower.

Marine 22 203 pm.

Outer waters... Expect seas to remain below SCA levels through
early early Tuesday. There is a 60% chance for SCA level gusts
across the western portion of the northern outer waters zone
(pzz670) starting early Tuesday morning, then expanding across the
entire outer waters by mid to late morning Tuesday. SCA winds and
steep seas should continue across the outer waters through at
least late Wednesday night or early Thursday morning.

Inner waters (near shore between pt. Piedras blancas to point
sal)... Winds should remain below SCA levels through at least
Tuesday morning. There is a 50% chance for SCA level gusts, mainly
across the western portions through Tuesday evening. There will be
a 60% chance for more widespread SCA level gusts Wednesday
afternoon through Wednesday eve.

For the inner waters south of point conception, conditions should
remain below SCA levels through at least Thursday. However, there
is a 30 percent chance of SCA level winds in the western santa
barbara channel each afternoon and evening Tuesday and Wednesday.

Lox watches warnings advisories
Ca... None.

Pz... Small craft advisory in effect from 2 am Tuesday to 3 am pdt
Thursday for zone 670. (see laxmwwlox).

Small craft advisory in effect from 9 am Tuesday to 3 am pdt
Thursday for zones 673-676. (see laxmwwlox).
