Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
500 AM PDT Sun Jun 7 2026

.SYNOPSIS...07/234 AM.

June Gloom morning low clouds across much of the region and below
normal temperatures will continue through Monday. A warming trend
will start Tuesday, becoming 5 to 10 degrees above normal
Wednesday through next weekend, and marine layer clouds will not
extend as far inland into the valleys but may still cling to the
beaches.

&&

.SHORT TERM (TDY-TUE)...07/227 AM.

The upper trough will continue to push through the region today,
leading to lowering heights, and a further deepening of the marine
layer, around 3500 feet for LA basin, and 1500-2000 feet across
the Central Coast. The deepening marine layer will likely lead to
areas of drizzle, especially for the LA county coastal slopes and
foothills. In addition, there will likely be a delay in clearing
for coast and valleys and lead to slightly cooler temperatures on
Sunday.

By Monday 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.

Gusty sundowner winds are expected to make a return on Monday
evening and Tuesday evening, with the strongest winds likely
focused across western portions from Gaviota to San Marcos Pass.
These areas have the potential to see gusts between 35 and 45 mph,
with isolated gusts to 50 mph possible near Gaviota. As a result,
wind advisories may be necessary as we draw closer.

.LONG TERM (WED-SAT)...07/341 AM.

Steady high pressure will setup over the region starting
Wednesday. Relatively minimal pattern changes are expected through
next weekend, and thus temperatures each day will generally be
around 5 to 10 degrees above normal. Expect highs at the beaches
and coastal plains in the mid 70s to mid 80s, and across the
valleys mid 80s to mid 90s. The Antelope Valley will see the
warmest temperatures, largely between 97-102 degrees.

There is some uncertainty in the temperatures along the Central
Coast and Paso Robles on Wednesday and Thursday. There is around a
50 percent chance of morning offshore flow across the area. This
would result in noticeably warmer temperatures, near 100 degrees
at Paso Robles and upper 80s possible at San Luis Obispo.
Additionally, there is also a 20 percent chance of morning
offshore flow south of Point Conception Wednesday and Thursday. If
this pans out, temperatures across much of Ventura and LA
Counties may be warmer than forecast (highs in the 80s at the
beaches and 90s across the coastal plains and valleys).

Morning marine layer clouds will continue each day, though may be
minimal if offshore flow develops. Higher 500 mb heights will
also reduce the inland extend of clouds, keeping them focused over
the beaches and coastal plains.

.AVIATION...07/1200Z.

At 0740Z at KLAX, the marine layer was 3100 feet deep. The top of
the inversion was 4000 feet with a maximum temperature of 18 C.

High confidence in forecasts for KWJF, KPMD 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 TAF. 20% chance of cigs lingering
through this afternoon. No significant easterly wind component is
expected.

KBUR...Moderate confidence in  TAF. Timing of flight category
changes could be +/- 2 hours of current forecast.

For the Outer Waters, moderate to high confidence in current
forecast. Through Thursday, high confidence in a combination of
Small Craft Advisory (SCA) level winds and seas. There is a GALE
WARNING over the two northern outer zones from late this
afternoon through tonight. Monday and Tuesday, there is a 30-40%
chance of Gale force winds during the same time period, with the
best chances on Monday. SCA winds are likely to persist through
Wednesday night, then weakening on Thursday.

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
near or above 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 today through Tuesday, mainly in the late
