Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
1054 PM PST Fri Feb 21 2025

.SYNOPSIS...21/945 PM.

High pressure over the eastern Pacific combined with weak to
moderate offshore flow will keep high temperatures 10-15 degrees
above normal through Monday, especially inland. However, the
warmest days are expected to be next Tuesday and Wednesday with
record highs possible in the 80s to lower 90s for coast and
valleys. Locally breezy northeast winds are possible at times.
Patchy morning low clouds and locally dense fog are possible near
the coast of Los Angeles and Ventura Counties through the weekend.

&&

.SHORT TERM (FRI-MON)...21/946 PM.

Breezy northeast winds have diminished as offshore flow weakens.
An area of stratus that briefly brought some dense fog to LA
County beaches between 4 and 6pm has shifted south to the OC but
latest satellite imagery is showing the stratus returning north
just as the HREF had been showing. So expect areas of dense fog
across the LA County beaches again later tonight through Saturday
morning. Could pose some visibility issues for LAX and other
airfields in the area.

Otherwise, a clear night in most areas and another chamber of
commerce day Saturday with highs mostly in the 70s, except mid to
high 60s near the beaches due to onshore flow returning by
afternoon. Farther inland though some offshore breezes to around
30 mph between the Hwy 14, 118, and 126 corridors.

Sunday and Monday will be fairly similar to Saturday, except less
wind inland and again some onshore breezes developing along the
coast. The 00z NAM shows a 3.7mb LAX-DAG gradient Monday
afternoon, so likely little change at the coast but a few degrees
of warming inland.

.LONG TERM (TUE-FRI)...21/124 PM.

For the extended, 12Z models start out in good synoptic agreement,
but begin to diverge noticeably later in the period. For Tuesday
and Wednesday, both models indicate upper level ridge will
strengthen again over the area with weak to moderate offshore flow
near the surface. On Thursday/Friday, models diverge dramatically
with the GFS moving an upper low across northern CA and into the
Great Basin while the ECMWF develops a meandering cutoff low off
of our coast.

Forecast-wise, Tuesday and Wednesday will be Chamber of Commerce
type days. Skies are expected to remain mostly clear with no hint
of marine layer stratus. The combination of the building upper
level ridge and offshore surface flow will allow for significant
warming across all areas with temperatures expected to peak in the
80s to lower 90s across most areas on Wednesday. These
temperatures will be hovering around record levels on Wednesday
for some areas.

For Thursday/Friday, forecast confidence takes a dramatic nose
dive. The GFS solution would indicate a dry pattern with
increasing onshore flow at the surface and a cooling trend. The
ECMWF solution on the other hand would keep some amount of
offshore flow in place, resulting in warmer temperatures. However,
the ECMWF solutions would also indicate the threat of some light
showers to the area. The NBM numbers lean towards the ECMWF and
there are slight chance POPs for some areas on Thursday and
Friday. However, confidence in any forecast details for the
Thursday and Friday time frame are very low.

.AVIATION...22/0647Z.

At 0537 at KLAX, the marine layer was 700 feet deep, with an
inversion up to 1900 feet with a temperature of 20 C.

High confidence in the current forecast for all terminals, except
for moderate confidence in the current forecast for Los Angeles
County coastal terminals. There is a moderate-to-high chance of
VLIFR to LIFR conditions at Los Angeles County coastal terminals
between 07Z and 16Z.

KLAX...Moderate confidence in TAF. Cigs could develop as soon as
07Z and as late as 12Z. VFR conditions should develop between 16Z
and 18Z. Any east winds should be less than 7 knots.

KBUR...High confidence in TAF.

.MARINE...21/952 PM.

For the waters southwest through northwest of the Channel Islands
and the nearshore waters along the Central Coast, there is a low-
to-moderate (20-40 percent) chance of Small Craft Advisory (SCA)
conditions (winds and seas) on Saturday afternoon and evening,
increasing to a moderate-to-high (30-50 percent) chance on
Sunday afternoon and evening. Winds are likely be the higher
chance scenario, but seas will be close to SCA levels through
Saturday night. There is an increasing chance of SCA conditions
into Monday and Tuesday with a high-to-likely (50-70 percent) chance
of SCA conditions on Monday, increasing to a likely-to-imminent
(60-80 percent) chance on Tuesday. There is also a low-to-moderate
chance of GALES during this time.

Across the southern California bight, wind and seas are likely to
remain below SCA levels through Sunday, then there is a low-to-
moderate (20-40 percent) chance of SCA level winds early next
week, especially during the afternoon and evening hours. The
highest chance will be across the western portion of the Santa
Barbara Channel.
