Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
230 PM PDT Sat Jun 6 2026

.SYNOPSIS...06/322 AM.

Temperatures will remain near to slightly below normal through
at least early next week as a series of low pressure systems move
through the region. Low clouds and fog will cover most of the
coast and valley locations through at least mid morning, clearing
to near the beaches each afternoon. A warming trend is expected
later next week.

&&

.SHORT TERM (TDY-TUE)...06/203 PM.

Low pressure systems moving through the Pac NW will continue to
keep temperatures on the cooler side across southwest California
at least one more day. In fact, the marine layer is expected to
deepen even further tonight, around 3500 feet in LA and 1500-2000
feet across the Central Coast. This is expected to delay the
clearing for coast and valleys and lead to slightly cooler
temperatures. Highs today across the inland areas are trending
5-10 degrees cooler than yesterday and expect at least a few more
degrees of cooling Sunday.

We`ll start to turn the corner Monday as high pressure starts to
be build in from the west. The marine layer will begin to shrink
with progressively earlier clearing times next week. Temperatures
will be gradually warming as well, especially inland, but
generally staying in the 80s in the valleys and 90s in the far
interior.

One feature to keep an eye on is the expected return of Sundowners
across southwest Santa Barbara County, peaking Monday and Tuesday
evenings with gusts between 40 and 50 mph, mainly west of Goleta.

.LONG TERM (WED-SAT)...06/230 PM.

High pressure is expected to strengthen across the eastern Pacific
and California at least through Wednesday. This will bring at
least some warming to most areas, but definitely favoring the
interior areas like the Antelope Valley and interior SLO and Santa
Barbara Counties which will be mostly immune to any onshore
influence. In those areas there is 60-80 percent chance of 100
degrees or higher by the end of next week. Coastal valleys will
warming as well but the latest ensemble pressure gradients suggest
at least a 5-7mb onshore flow each afternoon which should keep
warmer valley highs in the low to mid 90s and Downtown LA and
other intermediate areas between the coast and valleys in the in
the 70s to lower 80s. Night and morning low clouds and fog are
expected to be a daily occurrence across all coastal areas next
week as well as most coastal valleys through at least mid week and
possibly beyond depending on the strength of the high.

Sundowners are expected to weaken by Wednesday, but possibly
returning next weekend.

.AVIATION...06/1724Z.

At 1630Z at KLAX, the marine layer was 2500 feet deep. The top of
the inversion was 4400 feet with a temperature of 19 degrees
Celsius.

For 18Z TAF package, high confidence in forecasts for KWJF, KWJF
and KPRB. For all other sites, moderate confidence in forecasts
due to uncertainties with behavior of the marine layer. Timing of
flight category changes could be +/- 3 hours of current forecasts.

KLAX...Moderate confidence in 18Z TAF. There is a 40% chance that
MVFR CIGs do not scatter out this afternoon. No significant
easterly wind component is expected.

KBUR...Moderate confidence in 18Z TAF. Timing of flight category
changes could be +/- 3 hours of current forecast.

.MARINE...06/110 PM.

For the Outer Waters, moderate to high confidence in current
forecast. Today through Thursday, high confidence in a
combination of Small Craft Advisory (SCA) level winds and seas.
Additionally, there is a 60-80% chance of GALE force winds across
PZZ670/673 through tonight and GALE WARNINGs are in effect for
these areas. From Sunday through Wednesday, there will be a 20-30%
chance of Gale force winds.

For the Inner Waters north of Point Sal, high confidence in
current forecast. Today through Wednesday, SCA level wind are
expected, mainly in the afternoon and evening hours, with seas
approaching SCA levels. On Thursday, winds and seas are expected
to remain below SCA levels.

For the Inner Waters south of Point Conception, moderate to high
confidence in current forecast. For a majority of the southern
Inner Waters, high confidence in winds and seas remaining below
SCA levels through Thursday. The only exception will be the western
half of the Santa Barbara Channel, where there is a 40-60% chance
of SCA level winds Sunday through Tuesday, mainly in the late
afternoon and evening hours.
