Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1041 AM PDT Thu Jun 26 2025

.SYNOPSIS...25/158 PM.

Night and morning low clouds and fog will affect the coasts and
some valleys, otherwise mostly clear skies are expected across
the area with gusty onshore winds each afternoon. Temperatures
will continue to turn a bit warmer tomorrow, with little change
over the weekend into early next week.

&&

.SHORT TERM (TDY-SAT)...26/820 AM.

***UPDATE***

Latest satellite and surface observations indicated widespread
stratus/fog into the coastal valleys with clear skies elsewhere.
Current sounding data indicates marine inversion ranging in depth
from 1200 feet north of Point Conception to around 2200 feet
across the LAX Basin. No significant winds are observed.

Forecast-wise for the immediate short term, no significant issues
are expected. Current stratus blanket should dissipate by late
morning for most areas. The only exceptions may be the beaches
along the Central Coast and the Ventura south to Malibu where some
stratus may linger through the afternoon. Other than this stratus,
sunny skies will prevail through the day. Moderate onshore
gradients will generate the typical gusty southwesterly winds
across interior sections, but nothing approaching any advisory
concerns.

Overall, current forecast has good handle on the immediate short
term. So, no significant updates are expected.

***From Previous Discussion***

The main upper level flow is well north of the area and 588 dam
hgts along with very weak upper level flow will remain over the
area for the next 3 days. At the sfc there will be weak to mdt
onshore flow in the mornings and mdt to stg onshore flow in the
afternoons.

The marine layer is currently near 1000 ft and low clouds cover
the csts and most of the vlys. The shallower marine layer has
delayed the arrival of the low clouds into the LA vlys and there
will likely be less low clouds in the San Fernando Vly today than
ydy. Most areas will clear by late morning, but many beaches will
see delayed clearing with a few beaches staying cloudy all day.
With little change in the forcing over the next few days expect
this cloud pattern to repeat itself both Fri and Sat.

Max temps jumped nicely in the non coastal areas ydy as the trof
and cooler air moved out of the area. A slight 1 to 2 degree warm
up is fcst today with a 2 to 3 degree warm up on tap for Friday.
Saturday`s temps should be similar to Friday`s. Still given the
similarities between all three days would not be surprised if the
warming is less than this forecast. Max temps will remain a
little below normal across the csts/vlys and a little above normal
for the interior sections.

Look for 30 to 40 mph Sundowner Wind gusts each evening and
overnight for the southwestern portion of Santa Barbara County.
The onshore push to the east (~8mb) each afternoon will result in
gusty W-SW winds each day through Saturday across the Antelope
Valley and foothills.

.LONG TERM (SUN-WED)...26/1211 AM.

Not much excitement planned for the extended fcst. The EC and GFS
both agree that an upper trof will develop over the east Pac and
will then very slowly move into and over the state. Hgts will
lower only slightly from 588 dam to 586 dam. At the sfc there
there will be moderate to strong onshore flow to both the east and
north.

Look for a persistent night through morning low cloud and fog
pattern each day. The clouds will cover the coasts and most of the
vlys (the Santa Clarita Vly will likely be clear). Some west
facing beaches will likely stay cloudy for most of or all of the
day. Other than the low clouds skies will be clear.

There will be relatively little day-to-day change in temperatures
across the entire area. Beaches will be in the upper 60s to low
70` each day and the valleys will mostly be in the 80s, touching
the low 90s in warmest areas. The interior will see temperatures
in the upper 90s and approaching the low 100s, with warmest
temperatures in the Antelope Valley, foothills, and lower
mountain elevations. These max temps will mostly be a little below
normal for the csts/vly and generally a little above normal for
the interior.

Persistent onshore flow (~8mb onshore push to the east in the
afternoon) will bring gusty W-SW winds each afternoon and evening
to the Antelope Valley, and the typical sea breezes will be
slightly stronger.

.AVIATION...26/1739Z.

At 1706Z at KLAX, the marine layer was 1600 ft deep. The top of
the inversion was at 3500 ft with a temperature of 22 C.

High confidence in VFR TAFs for desert airfields (KPMD and KWJF).

Moderate confidence in remaining TAF sites. Timing of CIG/VSBY
restrictions may be off +/- 2 hours and flight cat minimums by
one. There is a 30% chance V/LIFR conds do not arrive at KPRB
between 12Z-18Z Fri. There is a 20% chance of LIFR CIGs at KSBA
and KOXR.

KLAX...Moderate confidence in TAF. Timing of CIG/VSBY restrictions
may be off +/- 2 hours. There is a 10% chance of LIFR CIGs from
03Z to 12Z Fri. No significant wind issues expected.

KBUR...Moderate confidence in TAF. Arrival and departure of CIGs
may be off +/- 2 hours. There is a 15% chance of LIFR CIGs from
06Z to 15Z Fri.

&&

.MARINE...26/811 AM.

Small Craft Advisory (SCA) winds are expected across the Outer
waters through Thursday night. Localized Gale force wind gusts
are likely (70% chance) across the northern portion of PZZ670
Thursday evening. There is a 40% chance Gales become widespread
enough to warrant a last minute GALE warning - will continue to
monitor trends. For PZZ676, the lull in winds this morning will
increase back to SCA levels this afternoon.

For the inner waters along the Central Coast, SCA winds are
expected Thursday (today) during the afternoon and evening hours.
SCA winds are not expected across the Santa Barbara Channel Today.
Although, cannot rule out localized gusts to 21 kts across far
western portions of the channel.

For the weekend, relatively benign conditions (light winds and
calm seas) are expected across the coastal waters.

Night to morning dense fog is possible through the weekend,
especially adjacent to the Central Coast.
