Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1103 PM PDT Fri May 9 2025

.SYNOPSIS...09/828 PM.

High pressure aloft will keep the weekend hot away from the coast.
Dense fog will continue to impact the coast. Onshore flow will
strengthen next week and bring much cooler conditions with low
clouds and fog pushing back into the valleys. There is a chance of
drizzle or light showers next Tuesday.

&&

.SHORT TERM (FRI-MON)...09/818 PM.

***UPDATE***

Friday was certainly a hot day, with a couple of records broken
(Woodland Hills and Burbank) and one that missed it by one degree
(Paso Robles). The high pressure aloft driving our mini heat wave
will change little through Saturday. As a result, temperatures
will be very similar on Saturday to today. The marine layer will
remain extremely shallow, but present enough to moderate the
beaches keeping them more mild than hot. Dense fog will be a
concern again. The fog cleared out almost completely this evening,
but should still reform tonight as southeast flow forms near the
coast. Coverage on Saturday should be a little less than Friday
however.

***From Previous Discussion***

High pressure aloft and weak onshore flow have combined to bring
hot temperatures to inland areas today. Woodland Hills has broken
a daily record with a high of 101 as of 1pm with the potential for
another degree or two before the cooling begins. Even San Luis
Obispo reached 90 today. In stark contrast to that areas near the
beaches were much cooler with highs there only in the 60s and
lingering areas of dense fog.

Expecting a fairly similar day tomorrow with temperatures +/- 2
degrees from today in most areas and the heat advisories will
remain in effect. Certainly a possibility of more broken records
across inland locations (Woodland Hills record is 99 Saturday).
Models are showing a very slight increase in onshore flow in the
afternoon but typically this does not have much impact except
possibly at the beaches. And again some areas of dense fog
expected along the coast.

High pressure weakens Sunday as the next upper low approaches the
Pac NW. However, the air mass is still quite warm and the increase
in onshore flow will mostly occur very late in the afternoon so
inland locations are still expected to reach the upper 80s to mid
90s. This is still 10-15 degrees above normal but not quite
enough for heat advisories. Some gusty winds expected later in the
day across southwest Santa Barbara County and the Antelope Valley

Much cooler weather Monday as the West Coast trough deepens and
extends farther south into California. Low clouds and fog are
expected to push into the valleys by Monday morning and high
temps will drop to 4-8 degrees below normal in most areas and as
much as 10-15 degrees below normal across SLO County. Afternoon
winds may approach advisory levels across the Antelope Valley.

.LONG TERM (TUE-FRI)...09/206 PM.

Overall a cool and breezy week with lots of marine layer stratus
across coast and valleys and even up some of the coastal mountain
slopes. The trough axis is expected to move through the area
Tuesday and while there isn`t much moisture with it, the
combination of strong onshore flow flow and cooling aloft will
create an environment favorable for night and morning drizzle and
even some very light showers. Many ensemble solutions continue to
show some light precip developing Tuesday morning in the San
Gabriel valley up against the foothills, but can`t rule that out
across other coast/valley/south facing mountain areas.

That system moves east Wednesday but weak troughing will continue
the remainder of the week keeping temperatures below normal with a
steady dose of night and morning low clouds and fog.

.AVIATION...10/0559Z.

At 0505Z at KLAX, the marine layer was under 300 feet deep. The
top of the inversion was 1000 ft with a temp of 30 degrees C.

High confidence in TAFs for inland sites.

Low to moderate confidence in TAFs for KSBA, KOXR, KCMA. There is
a 40 percent chc of no cigs at KOXR and KCMA. There is a 25
percent chc of LIFR cigs at KSBA 11Z-17Z. Cig timing could be off
by +/- 2 hours.

Moderate confidence in TAFs for KSMO, KLAX, and KLGB with a 25
percent chc of no cigs. Cig timing could be off by +/- 2 hours.
There is a 30 percent chc VLIFR conds.

KLAX...Moderate confidence in TAF. There is a 25 percent chance
of no low clouds. There is a 25 percent chance of 1/4-1/2SM FG
and Vi through 17Z Sat. Good confidence any east wind component
will remain below 7 kt.

KBUR...High confidence in TAF.

.MARINE...09/832 PM.

Small Craft Advisory or stronger winds are expected across the
outer waters through the weekend and potentially continuing
through early next week. Winds may drop below advisory levels
Saturday morning, especially across the outer waters south of
Point Conception, but good confidence in winds increasing back up
to advisory levels by the afternoon hours. There is also a 20-30%
chance for shorter lived, localized SCA level winds for portions
of the inner waters south of Point Conception this evening. Good
confidence in winds expanding into the Santa Barbara Channel and
the inner waters north of Point Sal each afternoon and evening
starting on Saturday. There is a 20-50 percent chance of Gales in
the Saturday night through Monday or Tuesday time frame with the
lowest potential across the inner waters south of the Channel
Islands.

Low clouds and dense fog will be common across the coastal waters
tonight into early Saturday morning.
