Area Forecast Discussion...UPDATED
National Weather Service Los Angeles/Oxnard CA
843 AM PST Fri Dec 5 2025

.SYNOPSIS...05/842 AM.

Light offshore winds will weaken through today. Benign weather
will continue this weekend with a low chance for morning coastal
fog. A significant warming trend will begin Sunday with
temperatures well above normal Monday through next Friday, peaking
Tuesday through Thursday.

&&

.SHORT TERM (TDY-SUN)...05/831 AM.

***UPDATE***

Frost/Freeze products have been allowed to expire and the only
change to the forecast this morning was removing low clouds and
dense fog from the southern Salinas Valley. Otherwise, the
forecast is on track and the short term will feature rather
inconsequential weather with no watches, warnings, or advisories
anticipated. Light offshore winds this morning will weaken through
the day, allowing for some cooling today.

The only caveat to the benign weather is the low chance for dense
fog at the coasts of Ventura and Los Angeles counties in the late
night to morning hours tonight through Sunday, and even lower
chances for Santa Barbara County coasts. Confidence is very low in
any marine layer development, but it will be shallow if it does
develop.

***From Previous Discussion***

Three days of benign very nice weather on tap for Srn CA. An upper
high will nose in from the west. Hgts will rise a couple dam each
day and will end up near 584 dam by Sunday. There will be weak
offshore flow through the period, but only in the 2 to 4 mb range.

Skies will be sunny through the period. There will be light, sub
advisory winds each morning.

Low temperatures in wind sheltered locations will be below normal
each morning due to the dry airmass and clear skies which will
allow for very efficient radiational cooling. Freeze warning and
frost advisories are in effect for this morning, but a few degrees
of airmass warming will likely bring low up just enough to
preclude frost/freeze products.

Max temps will cool across the most of the csts and vlys today
and Saturday due to the weaker offshore flow. The Central Coast
will be the exception due to a decent offshore push this morning. The
inland areas will warm each day as the airmass warms. All areas
will warm Sunday as the hgts peak and there is a slight bump up
in the offshore flow. Sunday`s max temps will mostly be in the mid
60s to mid 70s across the csts and vlys (mostly 3 to 6 degrees
above normal).

.LONG TERM (MON-THU)...05/255 AM.

The warm up will continue through next week. While all mdls are
warm the EC and its ensembles continue to advertise the most heat.
The east Pac ridge will continue to dominate the Srn CA weather.
There is decent agreement that on Monday and Tuesday the hgts
will be near 586 dam. After that the GFS weakens the high to about
580 dam while the EC keeps it near 586 dam on Wed and then 589 dam
on Thu. For perspective, the average Dec hgt is 571 dam.

At the sfc offshore flow will continue. The offshore flow will be
weak most of the time but will rise to moderate levels on Tuesday
when there will be gustier winds in the morning. But with no upper
level or thermal support its doubtful that there will be advisory
level winds on any of the days.

The ensembles do point to the EC`s solution and the max temps have
been adjusted upwards through the period. Even with this boost
there is a 30 percent chc that they are still too low. Right now
the forecast call for 2 to 4 degrees of warming Mon and 1 to 3
degrees on Tuesday. The csts will likely cool a degree or two Wed
as Tuesday`s offshore flow relaxes and allows for an earlier
seabreeze. Away from the csts max temps will rise another 1 to 2
degrees each day. Monday`s max temps will be 8 to 12 degrees above
normal and by Thursday most max temps will be 12 to 18 degrees
over normal (about 8 degrees at the coasts). Thursday`s highs will
be in the lower to mid 80s in the vlys and the 70s across the
csts.

.AVIATION...05/1629Z.

At 16Z over KLAX, there was no marine layer. A surface based
inversion top was at 600 feet and 16 degrees Celsius.

There is a 30% chance of LIFR FG on Saturday at KPRB 10-16Z. The
chance of any other lowered categories elsewhere is 10% or less.

KLAX...High confidence in VFR conditions through at least
Saturday, except for a 10% chance of LIFR FG Saturday 12-16Z. East
winds are likely at times in the morning hours, but the chance of
exceeding 8 knots is less than 10%.

KBUR...High confidence in VFR conditions through at least Saturday
with typical winds.

&&

.MARINE...05/829 AM.

Moderate confidence in low-end Small Craft Advisory (SCA) NW winds
for the Central Coast waters beyond 20 miles from shore starting
tonight or Saturday Night. NE winds near 20 knots likely each
night and early morning into next week nearshore from Port San
Luis and northward. Otherwise, moderate confidence in unusually
light winds and small seas through at least this weekend.

There is a chance of dense fog forming over the coastal waters
tonight or this weekend, with the highest chances south of Point
Conception. Confidence is low on timing and coverage.

Abnormally high tides will peak this morning then lower each day
through next week.
