Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
825 AM PDT Fri Jul 11 2025

.SYNOPSIS...11/133 AM.

Night through morning low clouds and patchy fog will affect the
coasts and lower valleys into next week. Max temperatures will
cool today and Saturday and will end up several degrees below
normal. There will be continued cooling through the middle of next
week with valley highs on Tuesday only in the 80s.

&&

.SHORT TERM (TDY-SUN)...11/747 AM.

***UPDATE***

An eddy spun up overnight, allowing marine layer clouds to push
into the coastal valleys south of Point Conception, including into
Burbank. The marine layer has risen to about 1000 ft south of Point
Conception while it remains under 500 ft north as a result of the
eddy. In addition, onshore gradients will continue to strengthen
into the afternoon, and clouds may remain hugging the coasts
through the day. These onshore gradients will also help cool down
the areas on the coastal side of the mountains (including the
coastal slopes) today, while the temperatures across the far
interior areas will remain in the low triple digits. Max
temperatures today will range from 60s to 70s across the beaches
up to 80s to mid 90s across the coastal valleys. Additionally, the
strong onshore push will bring gusty winds to the interior, such
as the Antelope Valley western foothills, where local gusts to 45
mph will be possible.

***From Previous Discussion***

The onshore push is stronger by 2 to 3 mb this morning compared
to ydy both to the north and east. As a result there is better
marine layer stratus coverage. By sunrise low clouds will cover
almost all of the coasts and much of the lower vlys. The increase
in marine layer and onshore flow will bring 1 to 2 degrees of
cooling to the csts and 3 to 5 degrees across the vlys. This
cooling will bring most cst/vly locations down to a couple degrees
blo normal. The onshore push this afternoon is forecast to be
near 9 mb and this is strong enough to keep a few west facing
beaches cloudy all day.

Saturday will be very similar to today. There will likely be a
little more marine layer clouds in the vlys as an eddy should spin
up. This will result it a few more degrees of cooling. Look for
70s and lower 80s for most of the csts (mid to upper 60s for the
Central Coast`s beaches) and mid 80s to mid 90s for the vlys. The
strong onshore flow will, again, keep a few beaches socked in with
clouds. Gusty west winds across the Antelope Vly may reach low end
advisory levels.

Very similar weather is likely Sunday as there will be little to
no change in the major weather parameters.

.LONG TERM (MON-THU)...11/133 AM.

Fairly dull weather on tap for the xtnd fcst. Weak ridging
extending from the SW will cover the state through Wednesday.
On Thursday weak cyclonic flow is forecast to move over the state.
Hgts will fall slowly through the period from 594 dam Monday to
590 dam on Thursday.

More importantly there will be mdt to stg onshore flow both to the
north and east. The afternoon push to the east is forecast to be
near 10 mb each day.

Look for night through morning low clouds and fog across the
coasts and into the lower vlys (the 590+ dam hgts should smoosh
the marine layer low enough to prevent deep vly penetration). The
strong onshore flow will likely mean slow to no clearing for many
beach areas.

Monday`s max temps will be near 70 at the beaches with 70s across
the rest of the coastal areas. The vlys will see max temps in the
80s and lower 90s. Tuesday`s max temps will be 2 to 4 degrees
cooler and end up 4 to 8 degrees blo normal for this time of year.
Temps will not change much from those readings on Wed and Thu.

The strong onshore flow will bring gusty likely advisory level
winds some of the mtns and the western portions of the Antelope
Vly and foothills. Additionally, the gusty winds across the mtns
and interior along with fairly warm temperatures and fairly low
humidities will bring an uptick in fire weather danger.

At this time there is no monsoon threat.

.AVIATION...11/1053Z.

At 08Z at KLAX, the marine layer was 800 ft deep. The top of the
inversion was near 2700 feet with a max temperature of 27 C.

High confidence in TAFs for KPMD, KWJF, and KPRB.

Moderate confidence elsewhere. Flight category changes may be off
by two hours and one flight category. There is a 20-30 percent
chance of IFR or lower cigs/vsbys for KBUR and KVNY through 17Z.

KLAX...Moderate confidence in TAF, except low confidence after 00Z
when flight category changes may be off by 3+ hours. There is a
10 percent chance of 6 kts east wind component at times between
10-17Z.

KBUR...Moderate confidence in VFR TAF. There is a 20-30 percent
chance of IFR or lower cigs/vsbys between through 17Z.

&&

.MARINE...11/824 AM.

No hazardous winds or seas expected through the forecast period.
Night to morning patchy dense fog is possible at times through
this weekend, with highest chances along the Central Coast.

&&

.LOX WATCHES/WARNINGS/ADVISORIES...
