Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
303 AM PDT Wed Aug 13 2025

.SYNOPSIS...13/302 AM.

It will be slightly cooler today. The cooling trend will continue
through Saturday and weekend temperatures will be around 6 degrees
below normal. Night through morning low clouds and fog will
continue along the coast and into some coastal valleys through the
period. A warming trend will kick off next Monday.

&&

.SHORT TERM (TDY-FRI)...13/302 AM.

The ridge will break down today and this will lead to a slight
cooling trend across the interior. Just slight enough to keep
conditions below heat advisory/warning thresholds. Above normal
temperatures are still forecast for the lower mtn elevations and
far interior, so people planning outdoor activities this afternoon
should be mindful of the possibility of heat danger. A bigger
cool down is on tap for the vlys as an eddy has lifted the marine
layer to over 1200 ft and low clouds have overspread the San
Gabriel and San Fernando Vly. The csts will not see much
temperature change, since these areas have been under a steady
marine influence. Max temps today in the vlys will mostly be in
the 80s with some higher readings in the western San Fernando Vly.

A north wind event will develop tonight as high pressure develops
to the NW and N. The strongest winds will be across the western
portion of the SBA south coast where gusts to 55 mph will occur.
The I-5 corridor and western Antelope Vly will also see gusty
winds to 40 mph which is just under advisory criteria.

Troffing will replace the ridge on Thursday. The slight lift from
the trof and continued onshore flow will bring low clouds to the
coasts and some of the vlys. Max temps will continue to cool
across the interior while the csts/vlys see little change.

Another round of north winds will occur and advisory level gusts
remain very likely for the western SBA county coast. Additionally
the I-5 corridor will also likely see some advisory level gusts.

The trof will remain over the state on Friday and hgts will fall
to 586 dam. The marine layer cloudiness more representative of
June than August will persist and some beaches may only see
limited clearing. Another 2 to 4 degrees of cooling everywhere,
save for the Central Coast which will warm 1 or 2 degrees, will
bring coast temps down to the 70s and lower 80s with the vlys
coming in with 80s and lower 90s. These max temps are mostly 3 to
6 degrees below normal.

.LONG TERM (SAT-TUE)...13/302 AM.

The troffing pattern will continue over the weekend with both days being
the coolest day of the next 7 as 586 dam hgts and up to a 9mb
onshore push to the east in the afternoon. Look for 1 to 3 degrees
of additional cooling Saturday and little change to those numbers
Sunday. Max temps will end up in the 70s across the csts and only
the 80s in the vlys. The Antelope Vly will only see mid 90s. Most
max temps will be 3 to 6 degrees blo normal, but the LA/VTA vlys
will be around 8 degrees under normal. The strong onshore push
to the east will generate gusty afternoon winds across the some
mtns and the western Antelope Vly. These winds will create locally
elevated fire wx conditions.

The strong upper high to the east will push westward starting
Monday and continuing into Tuesday. The strong onshore push to the
east will weaken and will only be moderate. The onshore flow to
the north will also weaken and may reverse to slightly offshore in
the mornings. Right now max temps are forecast to rise 2 to 3
degrees each day, but would not be surprised to see even greater
warming esp next Tue.

The night through morning low cloud pattern will continue all 4
days of the xtnd period. There will likely be more clouds in the
vlys on Sat and Sun. The weakening onshore flow plus increasing
hgts will likely keep the vlys cloud free on Mon and Tue with
quicker clearing times for the csts.

.AVIATION...13/0942Z.

At 09Z at KLAX, the marine layer was 1500 ft deep. The top of the
inversion was at 4500 ft with a temperature of 27 C.

High confidence in VFR conditions for at least the next 24 hours
at KPMD and KWJF with seasonally typical winds.

Chances for LIFR/IFR conditions at KPRB (60%) and KSBA (40%). All
other airports currently with ceilings, with moderate confidence
in similar clearing times as yesterday. Moderate confidence in
similar return ceiling times tonight at KSMX KSBP, and later
returns elsewhere, with 100-300 feet increase in ceilings.

Vis reduction due to FU from Gifford Fire is possible at times
for KSBP, KSMX, KSBA, & KPRB.

KLAX...High confidence in ceilings staying in MVFR category
OVC010-015 today. Clearing to VFR could occur as early as 16Z and
as late as 20Z. There is a 20% chance of brief bkn015 23-02Z.
Moderate confidence in VFR 03-06Z with return in the 06-10Z
window. Southeast winds likely, but high confidence in winds
staying under 8 knots.

KBUR...Moderate confidence in ceilings rising to MVFR by 12-14Z
and clearing by 15-17Z. Ceilings likely to return tonight, but
later than last evening with a likely return window of 09-12Z.

&&

.MARINE...13/204 AM.

High confidence in seasonally gusty NW winds across the waters
beyond 20 miles from shore between the Central Coast to San
Nicolas Island, with Small Craft Advisory (SCA) conditions common
each day through at least this week. Cannot rule out brief and
very localized gale force gusts to 35 knots from Point Conception
to San Nicolas Island each evening. The nearshore Central Coast
waters will flirt with SCA winds each afternoon and evening. The
western Santa Barbara Channel will also see SCA conditions late
each afternoon and evening, but unsure if it will be widespread
enough to warrant an SCA for the entire zone. The winds tonight
look strongest and most widespread, so will keep the SCA going.
All areas will see choppy seas from these winds in the late
afternoon through late night hours.

In addition, night to morning dense fog may continue at times
through Thursday mainly off the Central Coast. Moderate confidence
in some improvement by Friday.

A long period south swell will continue to bring hazardous waves
nearshore and elevate currents near harbor entrances through at
least this evening and possibly through Thursday evening.
