Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
811 PM PDT Fri Jun 12 2026

.SYNOPSIS...12/524 PM.

Night through morning low clouds and fog will cover most of the
coasts and many valley locations through the weekend and into
early next week. Highs will cool slightly through Sunday. Most
high temperatures will remain above normal, with the exception of
the coasts, which will see temperatures near to slightly below
normal.

&&

.SHORT TERM (FRI-MON)...12/809 PM.

***UPDATE***

Satellite shows marine layer clouds blanketing a large portion of
the coastal waters this evening. Those clouds are beginning to
move onshore along the Central Coast as well as parts of Ventura
and LA Counties.

Similar to yesterday evening, onshore pressure gradients are
bringing breezy west-southwest winds to many interior areas,
particularly the Antelope Valley where winds are gusting to
25-30 mph. Winds will slowly subside through the night, then pick
back up tomorrow afternoon and evening.

Marine layer stratus and fog will continue to push inland
overnight tonight, becoming widespread along coasts and coastal
valleys by morning. Expect high temperatures tomorrow to cool by
a degree or two regionwide.

***From Previous Discussion***

Very typical June weather will dominate the short and long
term period across Southern California. Our CWA will remain
situated under the southeastern periphery of the ridge. At
the surface, persistent moderate to strong onshore flow is
expected (strongest in the afternoon).

Marine layer stratus will behave similarly each day and night.
Expecting early evening arrival and late morning/early afternoon
departure. Locations across the immediate coastline could remain
cloudy all day (if not most) due to strong pressure gradients.

This morning there was localized patches of dense fog across the
Santa Maria Valley. Due to lighter winds, there is a higher chc
of dense fog tomorrow morning. This should allow the clouds to
settle at the sfc. There is a 20% chance a dense fog advisory
will be needed.

The strong (8-9mb) LAX-DAG in the afternoon will bring enhanced
seabreeze and gusty winds (20-30 mph locally 35 mph) across the
Antelope Valley each day. Winds will remain below advisory levels
across the CWA.

The increasing onshore flow and expanded marine layer coverage
will bring a slow cooling trend through the weekend. By Sunday,
csts/vlys should be fairly close to normal temperatures. While
the mtns & interior will remain above normal thru the weekend.
Csts: 70s - low 80s. Vlys: mid 80s - low 90s. near 100 across
Antelope Valley.

.LONG TERM (TUE-FRI)...12/203 PM.

Heights are expected to peak Monday into Tuesday in response
to aforementioned ridge nosing in from the north and west.
Due to persistent moderate to strong onshore flow not expecting
too much warming for csts/vlys (remaining fairly close to normal).
By Tuesday, the far interior should be around 10 degrees above
normal. 100 degree readings are possible to likely across the
Cuyama and Antelope valleys. Unlikely that we will need any
heat products.

Thereafter, the ridge is expected to break down and at the sfc
onshore flow will increase even more to the N and E. Subtle
differences in guidance but the flow turns zonal and even
a bit cyclonic as there is some agreement of a dry shortwave
trough approaching the coast by Friday. This will result in a
cooling trend with near to below normal temperatures into the
weekend.

No major wind issues expected, but typical gusty SW-W winds
in the afternoon will occur across the Antelope Valley (likely
strongest Wednesday into Friday).

.AVIATION...13/0023Z.

At 1708Z at KLAX, there was no marine layer. The top of the
inversion was at 2300 ft with a maximum temperature of 27 C.

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

Moderate confidence in TAFs for KBUR and KVNY with a 20 percent
chc of LIFR/IFR cig and vis 12Z-15Z.

Moderate confidence in remaining TAFs. Timing of CIG/VSBY
restrictions may be off +/- 2 hours and flight minimums by one
category.

KLAX...Moderate confidence in the 00Z TAF. The timing of CIGs
arrival and dissipation could differ by +/- 2 hours from TAF
times. No significant east wind component expected.

KBUR... Moderate confidence in TAF. There is a 20 percent chc of
LIFR CIGs 12Z-15Z.

&&

.MARINE...12/804 PM.

Moderate to high confidence in current forecast. Conditions are
generally expected to remain below Small Craft Advisory (SCA)
levels across the waters through the forecast period.

Local gusts to around 20 kts are affecting the waters near Point
Conception, and also along some of the LA County Beaches. This
pattern is likely to repeat each afternoon to evening period,
especially along the LA Coast, through Monday.

&&

.BEACHES...12/809 PM.

A couple of long period southerly swells (14 seconds and 18
seconds) will move into the coastal waters on Saturday and
continue through early next week. A Beach Hazard Statement is in
effect from Saturday morning through Monday evening due to
elevated surf of 3 to 6 feet on south-facing beaches of Ventura
County Beaches, Malibu Coast, Los Angeles County Beaches, and
Southern Santa Barbara County Beaches.

Evening tides of near 7.5ft are predicted from Saturday through
Tuesday. The combination of the unusually high tides with elevated
surf could result in minor to locally moderate coastal flooding
for south exposed coasts, along with potential for sneaker waves.
Even as tides lower, another southerly swell arrives which could
extend concerns into Wednesday or Thursday. Stay tuned for
updates.
