Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
1245 PM PDT Sat May 30 2026

.SYNOPSIS...30/1226 PM.

Warming and drying through most of next week. June Gloom clouds
will be prevalent over coastal areas through next week, but will
be limited Sunday and possibly Monday, leading to the warmest two
days. Mountains and interior areas will likely see the warmest
conditions around Wednesday to Thursday of next week. Locally
gusty north winds likely through Monday morning, then increasing
onshore through the week.

&&

.SHORT TERM (TDY-TUE)...30/1243 PM.

The well advertised warm and dry period is underway and 24 hour
trends show up to 15 degrees of warming so far, warmest over
interior mountains and valleys. Additional 5-10 degrees of warming
expected for tomorrow as high pressure strengthens and offshore
winds limit marine influences at the coasts and coastal valleys.
An uptick in onshore flow will allow for temperatures to decrease
slightly on the coastal side of the mountains Monday and Tuesday
while interior areas will continue to warm up.

Wind advisories have been issued for Southwest Santa Barbara
County and the I-5 Corridor from this afternoon through Sunday
morning, where northwest to north winds are expected to be 20-30
mph with gusts to 50 mph. Winds 15-25 mph with gusts to 40 mph
will be common elsewhere across interior mountains and foothills
tonight. Fairly light northeast winds will be common Sunday
morning, especially over interior mountains and foothills of LA
and Ventura Counties. North winds will again become prevalent
Sunday night into Monday, but a notch weaker. Thus, wind
advisories are not anticipated. Onshore flow is expected to
increase to the north and south Monday through Tuesday.

Low clouds have filled in much of the coasts and valleys north of
Point Conception. South of Point Conception, small pockets of
marine layer clouds have formed, but skies remain clear for most
of the area. Expected marine layer clouds to burn off later today,
then low confidence in the exact return and extent of marine layer
clouds tonight. More expansive coverage anticipated into Tuesday.

.LONG TERM (WED-SAT)...30/1242 PM.

High pressure aloft will continue to steadily climb through
Wednesday and Thursday, before slowly lowering into the weekend.
While some uncertainty exists in the exact temperatures,
confidence is high that Wednesday and Thursday will be the
warmest days over the interior, as temperatures will likely top
out between 90 and 100 degrees. On the coastal side of the
mountains temperatures will remain warm-ish but look to drop some
from the Monday peak as we head towards the end of the week thanks
to the strengthening onshore flow. The magnitude of that cooling
will depend on the extent of the marine layer coverage. But this
trend also looks locked in as all the ensembles show strengthening
onshore pressure gradients to the north and east through the
week. Heat Advisories and Warnings through the period remain
unlikely. Gusty onshore winds should be expected over the interior
sections through the end of the week.

Low to moderate confidence in Coastal and valley TAFs, high
confidence in desert TAFs.

Moderate confidence in timing of flight cat changes (plus or
minus 3 hours). There is a 30% chance of IFR/LIFR conds at KPRB
and KSBP overnight into Sunday morning, and a 40% of VFR
conditions through the period at KSMX. There is a 30% chance of
IFR-MVFR conds at KOXR, KCMA, KBUR, and KVNY overnight into
Sunday morning, and a 20% chance of VFR conds through the period
at KSMO, KLAX, and KLGB.

Low-end LLWS possible at KSBA 06-10Z Sunday.

KLAX...Moderate confidence in TAFs. There is a 20% chance of VFR
conds through the period. High confidence that any east winds
will stay under 8 knots.

KBUR...Moderate confidence in TAF. There is a 30% chance of
BKN008-12 11Z-16Z Sunday.

.MARINE...30/841 AM.

For the Outer Waters from the Central Coast to San Nicolas Island,
moderate to high confidence in current forecast. High confidence
in a combination of at least Small Craft Advisory (SCA) level
winds and seas through at least most of next week. There is a 60%
chance of low-end Gale Force winds tonight south of Point Sal
(Gale Warning issued), and a 30% chance to the north. There is a
40% chance of Gale force winds returning on Wednesday.

For the Inner Waters north of Point Sal, moderate to high
confidence in current forecast, with daily afternoon and evening
SCAs through Sunday. For Monday through Wednesday, there is a
40-50% chance of SCA level winds in the afternoon and evening
hours.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. There is a 60% chance of SCA winds
over the western half of the Santa Barbara channel tonight, with
lower chances to follow through early next week. The remaining
areas will see local winds near SCA in the afternoon hours, but
likely not expansive enough to warrant an SCA.

All waters will see choppy seas due to the winds in the region,
especially in the afternoon and overnight hours.
