Synopsis 21 254 am.

Afternoon temperatures will peak this afternoon with a cooling
trend expected through the end of the week. High temperatures
will remain above normal through Thursday. High pressure will
build back in this weekend into next week. There will be areas of
night through morning low clouds and fog for most coastal areas
and possibly affecting a few coastal valleys into this weekend.

Short term (tdy-fri) 21 246 am.

Latest goes-w fog product imagery indicted mostly clear skies
except for low clouds and patchy fog across much of the santa
barbara central coast and into the santa ynez valley. A northerly
surface gradient between sba-smx continued to be over -3 mb as of
2 am. This was causing gusty northerly winds across the western
portion of the santa barbara south coast and adjacent foothills,
strongest west of refugio. Sustained winds remain over 30 mph with
gusts around 40 mph with highest gusts reaching the lower 50s last
evening. A wind advisory remains in effect until 3 am for this
area. Another wind advisory will likely be issued this morning valid
for this afternoon and overnight hours once again tonight for the
same location.

Synoptically, a 594 dm high was located over the eastern pacific
extending eastward over much of southern california. An upper
level trough located across the west coast from northern
california into the pac NW will dig farther south into socal
Thursday Friday bringing a cooling trend across most areas. Today
will be the warmest over the next few days with highs 2-6 degrees
warmer than yesterday. Triple digit heat is expected across the
antelope valley, salinas river valley and should hit 100 degrees
at woodland hills. Otherwise, most valleys will reach the mid to
upper 90s as the coastal areas remain mild over the next few days.

Night through morning low clouds are expected to be more
widespread across the central coast with only patchy low clouds
developing across the la county coast and possibly reaching the
oxnard plain. This stratus will continue Thu night into Friday.

Possibly more widespread S of point conception. Higher confidence
for clear skies across the sba south coast due to the sundowner
winds this evening into Thu morning.

For Thursday, expect high temps to lower 2-4 degrees, with an
additional 2-6 degrees of cooling on Friday. The one exception
will be across the salinas river valley including paso robles where
highs will go from the upper 90s on Thursday to the lower to mid
80s on Friday as cooler southerly flow moves into the area.

The pattern becomes a bit more complex after Friday as the national
hurricane center is expecting a high chance of a tropical depression
forming just west of southern mexico over the pacific. The gfs
shows this disturbance moving north parallel to the baja peninsula
but loses a lot of its punch by Sunday.

Long term (sat-tue) 21 309 am.

Overall, a few degrees of warming is expected this weekend into
early next week as high pressure builds in over the region. Moderate
onshore flow is expected to remain in place so will likely deal
with a relatively shallow but widespread marine layer across most
coastal areas during the night and morning hours. High
temperatures will rise a few degrees with most valleys in the mid
to upper 90s. The antelope valley will experience triple digit
heat, but not much higher than normal for this time of year.

The GFS continues to show a tropical cyclone spinning up over the
pacific just west of southern mexico on Friday and tracking north
parallel to baja. It quickly weakens as it reaches southern baja
Saturday. It's possible there will be some mid to high level
remnant clouds moving over across southern california by Sunday,
but remaining too dry at lower levels to pose much of a risk for
convection.

Aviation 21 0644z.

At 0545z, the marine layer was 800 feet deep at klax. The top of
the inversion was around 1350 feet with a temp of 26c.

Areas of low clouds have pushed into the central coast this evening.

Low clouds are expected to become widespread on the central coast
and in the santa ynez valley overnight with generally lifr to vlifr
conds. Skies should clear by mid morning, except late morning near
the coast. Elsewhere, skies are expected to remain clear, with
just a chance of ifr CIGS in coastal sections of l.A. County.

Klax... Moderate to high confidence in the 06z taf. There is a
20-30% chance ifr CIGS between 10z and 16z.

Kbur... High confidence in the 06z TAF withVFR conds thru the pd.

Marine 21 359 am.

For the outer waters, moderate to high confidence in the forecast.

Small craft advisory (sca) level winds are expected to increase
to gale force this afternoon and continue thru late tonight. Then,
sca level winds are likely late tonight thru Thu evening. Conds
are expected to be below SCA levels late Thu night thru sun.

For the inner waters north of pt. Sal, moderate confidence in the
forecast. SCA level winds are expected this afternoon thru this
evening, and there is a 30-40% chance that SCA level winds will
continue thru late tonight. There is a 40% chance of SCA level
winds during the afternoon and evening hours thu. Then, SCA conds
are not expected Thu night thru sun.

For the inner waters south of pt. Conception, moderate to high
confidence in the forecast. SCA level W to NW winds are expected
across western portions of the sba channel late this afternoon
thru late tonight. Otherwise, SCA conds are not expected thru sun.
