Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
249 AM PDT Wed Jun 3 2026

.SYNOPSIS...03/236 AM.

Warm and dry conditions can be expected through most of this
week. There will be plenty of morning low clouds and fog across
most of the coasts and many valley areas, but otherwise skies
will remain mostly clear. Northerly winds will affect areas of
southern CA tonight.

&&

.SHORT TERM (TDY-FRI)...03/240 AM.

A 1600 ft deep marine layer, onshore flow and a weak eddy have all
teamed up to bring low clouds much of the csts and some of the
vlys. At the same time a ridge is nosing into the middle of the
state from the north and in addition to creating rising hgts it is
also bring northerly flow to the area. This northerly flow will
bring an earlier clearing of the low clouds to many areas this
morning. The sunny afternoon skies, northerly flow and rising hgts
will bring 3 to 6 locally 8 degrees of warming to all areas
today. Vly temps will reach the mid 80s to lower 90s this
afternoon or 3 to 6 degrees above normal.

The northerly flow will peak tonight and advisory level gusts are
likely (70-80 percent chc) across the western portion of the SBA
south cst and portions of the I-5 corridor.

There is a fairly tricky low cloud forecast Thursday morning as a
decently strong eddy competes with the offshore flow from the
north. The eddy will likely bring low clouds to the coasts of LA
and VTA counties and portions of western SBA county. The north
flow, however, will keep the vlys, the SBA south coast and SLO
county cloud free. Max temps will not change much with all areas
experiencing above normal temps save for the beaches which will
end up a few degrees under normals due to the strong onshore flow
in the afternoon.

No eddy is forecast for Friday morning and there will not be
enough oomph to lift the low clouds into the vlys. Onshore flow to
the north and east will allow low clouds to cover most if not all
of the coastal areas. The ridge breaks down and this along with
the strong afternoon onshore flow will cool most areas by 2 to 4
degrees.

.LONG TERM (SAT-TUE)...03/236 AM.

Troffing and mdt-stg onshore flow will dominate the xtnd period.
This will bring very June like conditions to the area on all 4
days. Onshore flow will be strongest over the weekend and the low
clouds will penetrate deep into the vlys and will likely not
clear at all from many beach and nearshore areas while the rest of
the csts/vlys see slower than normal clearing. 3 to 5 degrees of
cooling Saturday will be followed by 1 to 3 additional degrees on
Sunday. Sunday`s max temps will end up in the upper 60s to mid 70s
across the csts and a degree or 2 either side of 80 in the vlys.
These max temps are mostly 2 to 4 degrees blo normal.

The onshore flow relaxes some on Mon and Tue and this will bring
earlier clearing times for the marine layer stratus as well as a
few degrees of warming each day.

.AVIATION...03/0948Z.

At 0832Z at KLAX, the marine layer was 1600 feet deep. The top of
the inversion was near 4000 feet with a temperature of 22 C.

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

Moderate confidence in remaining TAFs due to uncertainty in cigs
timing. VFR transition could be off by -1 hour or + 90 minutes.
Cig hgts could be off by +/- 200 ft.

KLAX...Moderate confidence in TAF. VFR conds may not arrive until
21Z. Cigs may rise to 018 by 15Z. No significant east wind
component expected.

KBUR...Moderate confidence in TAF. There is a 20 percent chc
of no low clouds. VFR conds could arrive anytime as early as 15Z.

&&

.MARINE...03/205 AM.

For the Outer Waters from the Central Coast to San Nicolas
Island, moderate to high confidence in current forecast.
GALE WARNINGS have been issued starting this afternoon through
Thursday morning. Winds will be the strongest across the northern
waters (gusts to 40 kt). Seas will peak 12-15 ft during this
timeframe. There is a 30-40% chance that Gales may linger Thursday
afternoon through Saturday across the northern waters. Otherwise,
SCA conditions (winds and/or seas) are likely to persist through
the weekend.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast. Winds will increase to SCA levels
early this afternoon, with a 70% chance of Gales by late
afternoon into late night hours. Otherwise, SCA winds are likely
to persist through Thursday evening. After decreasing some Friday,
winds may increase to SCA levels again Saturday, and seas will
hover near advisory levels across the western portion.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. There is a 50 percent chance of
SCA winds Wednesday late afternoon and evening, and again
Thursday, and Sunday across the western portion of the Santa
Barbara Channel.
