Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
948 AM PDT Mon Jun 16 2025

.SYNOPSIS...16/939 AM.

High pressure over the region will maintain very warm temperatures
through much of the coming week, especially away from the coast
and across the interior portions of the area. Gusty northerly
winds will develop once again tonight across southern Santa
Barbara County and through the Interstate 5 Corridor. A gradual
cooling trend will develop late in the week.

&&

.SHORT TERM (TDY-WED)...16/948 AM.

***UPDATE***

It`s going to be a warm week across the region, but especially
inland where temperatures near or slightly above 100 are expected
each day. Temperatures this morning are generally running a couple
degrees above yesterday at this time but a slight increase in
onshore flow today should compensate for that by afternoon leading
to similar if not slightly cooler highs. Tuesday is expected to be
a a degree or two warmer as the high pressure ridge gets stronger
and onshore flow weakens. Another round of gusty Sundowner winds
is expected across southern Santa Barbara County tonight and
tomorrow night along with the I5 corridor.

***From Previous Discussion***

Ridging continues on Wednesday and the airmass over the interior
will warm by 3 to 6 locally 8 degrees. A different story for the
csts and vlys, however, as an eddy is forecast to spin up driven
by the momentum from the outer water winds. The eddy will likely
bring stratus to most of the LA/VTA vlys. The north flow across
the SBA south coast will probably keep that area clear. The low
clouds and stronger onshore flow will bring 6 to 12 degrees of
cooling to the LA/VTA csts and vlys. This will lower max temps to
only 3 to 6 degrees above normal with 70s for most coastal sites
and 80s in the vlys.

.LONG TERM (THU-SUN)...16/1219 AM.

Wednesday`s ridge will slowly be nudged eastward by an upper low
rotating out of the Gulf of Alaska. This low will move southward
and eventually move though the PACNW over the weekend. The flow
over Srn CA will gradually become more cyclonic as the upper low
progresses. Hgts will start out at an above average 589 dam but
will lower to 580 dam by Sunday afternoon.

At the sfc, there will be a 7 to 9 mb onshore push to the east in
the afternoons and about a 4 mb push in the mornings. The N/S
gradient will vary diurnally from offshore in the morning to
onshore in the afternoons.

The increased onshore flow will combine with increased cyclonic
turning to reinvigorate the marine layer stratus pattern. Look for
June Gloom conditions with night through morning low clouds and
fog covering most of the csts and vlys. The offshore push from
north will likely keep the Santa Clarita Vly and portions of the
SBA south coast cloud free. Clearing will be slow across the csts
and vlys with no clearing at many west facing beaches.

Max temps will drop each day Thu through Sat and will then rebound
slightly Sun as the onshore push weakens a little. By Saturday
most max temps will be blo normal. The interior will see the
biggest drop in temperatures. The Antelope Vly, for example will
cool from 100 to 101 degrees Thu to 88 to 90 degrees Saturday.

The strong onshore push to the east will bring gusty afternoon
southwesterly winds across interior sections, especially the
Antelope Valley.

.AVIATION...16/1642Z.

At 1620Z at KLAX, the marine layer was 1000 ft deep. The top of
the inversion was around 4500 ft with a temperature of 26 C.

Moderate confidence in TAFs for KSBP, KSMX, KSMO, KLAX, and KLGB.
There is a chance for IFR cigs at KLAX (20%) and KSMO (15%), and
a 30% chance for KLGB to remain VFR. For KSBP and KSMX, there is a
30% chance for vsbys 1/2SM or less between 10Z and 16Z.

High confidence in remaining TAFs.

KLAX...Moderate confidence in TAF. There is a 20% chance for cigs
005-010 at KLAX between 09Z and 16Z. There is a 10% chance an
east wind component reach 8 kts between 12Z and 17Z Tue.

KBUR...High confidence in TAF.

&&

.MARINE...16/824 AM.

High confidence in gusty Small Craft Advisory (SCA) level
northwest winds across the Outer Waters and Inner Waters along the
Central coast through the week. Lulls in winds along the Central
Coast are likely in the overnight and early morning hours. A Gale
Warning is in effect for the Outer Waters from this afternoon
through Tuesday night, and for the northern Inner Waters for this
afternoon/evening. Seas will also approach 10 feet at times
through the week. Gale force winds will be possible again by the
end of the week.

Gusty winds for western and southern portions of the Santa
Barbara Channel in the afternoon and evening hours are likely
through Tuesday, with lower confidence thereafter. A Small Craft
Advisory will start this afternoon and lead into a Gale Watch for
Tuesday afternoon/evening, with less impacts expected near Santa
Barbara, Ventura, and Channel Islands Harbors.

Moderate confidence in conditions remaining below advisory levels
in the Inner Waters off the Los Angeles and Orange County coasts
through the week. However, localized WNW SCA level wind gusts may
occur in the afternoon and evening hours near Malibu and through
portions of the San Pedro Channel today and Tuesday.
