Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1121 PM PDT Fri Jun 6 2025

.SYNOPSIS...06/750 PM.

Night through morning low clouds and fog will continue for the
next several days over the coast and valleys with slow, if any,
clearing at the coast. A warming trend will develop for the
weekend and through next week, especially away from the beaches.

&&

.SHORT TERM (FRI-MON)...06/738 PM.

***UPDATE***

The low clouds and fog have cleared out more than expected, with
clouds just over the Los Angeles County coasts. All the parameters
are there for solid coverage over most coastal and some valleys by
daybreak tomorrow, but it is awfully clear out there right now.
Will have to wait and see. Updated to forecast to better reflect
the current conditions. The rest of the forecast looks on track
with no changes needed.

***From Previous Discussion***

An upper low over the Bay Area is expected to be nudged a few
hundred miles over the Pacific which will allow heights and
thicknesses to rise over the weekend into Monday, leading to a
decreasing marine layer depth and 1-3 degrees of warming each
day, especially inland. High temps expected to reach the low to
mid 90s in the warmest valleys while coastal areas are in the
upper 60s and 70s. No impactful weather expected except possibly
some dense fog along the Central Coast and some of the LA/Ventura
valleys and some breezy afternoon/evening winds across the deserts
and southwest Santa Barbara County.

.LONG TERM (TUE-FRI)...06/201 PM.

One additional day of warming is expected on Tuesday as the upper
low moves into AZ while a little ridge pops up over CA. Highs
will top out around the mid 90s for coastal valleys and around
100 in the Antelope Valley. Not expecting temperatures to be high
enough for heat advisories.

Then a slow cooling trend the rest of the week as a trough
develops over the Pac NW.

At 0538Z at KLAX, the marine layer was 1600 feet deep. The top of
the inversion was at 4500 feet with a temperature of 22 C.

High confidence in VFR TAFs for KPMD and KWJF.

Moderate confidence in all remaining TAFs with timing of flight
category changes possibly off by 2 hours and 1 flight category at
times. Site KSBA, KSMX and KSBP have a 20-30 percent chance of
MVFR conds for the overnight period, with no IFR conds. KPRB has
a 20-30 percent chance of IFR/LIFR cigs/vsbys between 10Z-16Z.
There is a 10-20 percent chance that VFR conds prevail at KVNY,
and also a 20 percent chance of MVFR conds (no IFR) at KBUR and
KVNY. Afternoon VFR transitions may occur at sites with no
clearing 20Z Sat-03Z Sun, and there is a 20% chance of no VFR
transitions at KSMO and KLAX.

KLAX...Moderate confidence in TAF. There is a 20% chance of conds
lowering to 3SM BR BKN008 overnight. There is a 20% chance of no
clearing Sat afternoon. No significant east wind component
expected.

KBUR...Moderate confidence in TAF. There is a 20 percent chance
of MVFR conds (no IFR). Timing of VFR transition may be off by +/-
2 hours.

.MARINE...06/802 PM.

Northwest to west winds are expected this weekend, especially
across the waters south of Point Conception. There are increasing
chances for SCA winds across the waters around Pt. Conception,
Northern Channel islands, and down to San Nicolas Saturday (40%)
into Sunday (60%). Short period choppy seas are likely across all
of the waters, including nearshore.

Next week will be see increasing chances and coverage of SCA
winds across the outer waters, pushing into the western portion of
the southern inner waters at times, and seas building towards SCA
levels mid- week and beyond. Confidence is low (seas) to moderate
(winds).

Dense fog may become more common this weekend into early next week
focused north of Point Conception and especially during the
evening to morning hours.
