Area Forecast Discussion
National Weather Service Los Angeles/Oxnard CA
840 PM PST Fri Jan 16 2026

.SYNOPSIS...16/518 PM.

High pressure and offshore flow will bring very warm and dry
conditions to the region through the weekend along with gusty
northeast winds at times across Los Angeles and Ventura Counties.
A slow cooling trend will continue, but above normal temperatures
are expected at least into early next week.

&&

***UPDATE***

A high amplitude ridge of high pressure aloft along with an
offshore pressure gradient at the surface have combined to produce
moderate, gusty Santa Ana Winds across portions of LA and Ventura
Counties. The strongest winds this evening are over the mountains,
with Magic Mountain Truck Trail coming in at 61 mph gusts, and 45
mph gusts at the Chilao RAWS. The LAX to Daggett gradient is
currently -5.3 mb as of 800 PM and is forecast to strengthen
further overnight. With some upper level support also involved,
feel that a Wind Advisory will be needed for the mountains and the
typical wind-prone valleys. Gusts of 45-50 mph are likely over the
mountains, with the western Santa Monicas on the lower end of that
range. The valleys will see gusts of 35 to 40 mph. The winds are
expected to decrease some Saturday afternoon and evening, then
increase again Saturday night into Sunday but should be somewhat
weaker.

***From Previous Discussion***

High pressure aloft remains in full control over the entire West
coast and that will continue at least through Wednesday. Closer to
the surface, moderate to strong offshore flow is expected to
continue at least through Sunday. There was a slight decrease in
offshore flow this morning which was just enough to allow some low
stratus to move into some beach areas for a few hours. However,
offshore trends resumed this afternoon and probably won't be a return
of that tonight except possibly along the Central Coast. Highs
today have again surged into the 80s across most coast/valley
areas except the beach areas. With a slight increase in offshore
flow again tonight and Saturday, expected a very similar day in
most areas with highs again 10-20 degrees above normal. And with
that offshore flow increase there will also be an increase in
Santa Ana winds across portions of LA/Ventura Counties. Latest hi
res models are showing winds very close to advisory levels across
the usual areas favored for east winds.

Offshore flow is expected to slowly decrease Sunday and Monday
which will allow cooler onshore flow to move in sooner, however
highs will still be in the mid 70s to lower 80s at least and
possibly still some mid 80s in the warmer valleys. As gradients
weaken there will be an increasing chance of dense fog near the
coast and most beach areas will top out in the 60s.

.LONG TERM (TUE-FRI)...16/839 PM.

High pressure aloft remains in full control over the entire West
coast and that will continue at least through Wednesday. Closer to
the surface, moderate to strong offshore flow is expected to
continue at least through Sunday. There was a slight decrease in

.AVIATION...17/0117Z.

At 2351Z at KLAX, there was a surface-based inversion. The top of
the inversion was near 1500 feet with a temperature of 25 degrees
Celsius.

For 00Z TAF package, high confidence VFR conds for Sites away
from the coast, except for a 20% chance of brief or periodic LIFR
at KPRB. For coastal sites moderate to high confidence
overall, with reduced confidence for the Central Coast where
there is a 20-30% chance of LIFR/VLIFR conditions 10Z-18Z. For
the L.A. County Coastal sites, there is a 10-20% chance of
LIFR/VLIFR conds.

KLAX...Overall, high confidence in the 00Z TAF as CAVU conditions
are anticipated through the period. However, there is a 10-20%
chance of LIFR/VLIFR conditions 10Z-18Z. No significant easterly
wind component is expected.

KBUR...High confidence in the 00Z TAF as CAVU conditions are
anticipated through the period. There is a 30-40% chance of light
to moderate LLWS and turbulence 06Z-18Z.

&&

.MARINE...16/834 PM.

Overall, high confidence in current forecast for all of the
coastal waters. Through Wednesday, winds and seas are expected to
remain below Small Craft Advisory (SCA) levels. However, there
will be a 30% chance of SCA level northeast winds from Point Mugu
to Santa Monica Saturday morning.

Dense fog with low visibilities will continue to impact the
coastal waters through the weekend. The most widespread coverage
is expected across the Outer Waters and south of the Channel
Islands. Visibilities of one nautical mile or less can be
expected.
