Area Forecast Discussion
National Weather Service San Diego CA
835 PM PST Mon Feb 2 2026

.SYNOPSIS...
Slightly cooler today with temperatures still be above seasonal
averages. Patchy dense fog over the coastal waters could move
ashore again this evening, becoming more widespread tonight into
Tuesday morning. Warmer Tuesday through Thursday with periods of
weak to locally moderate Santa Ana winds. Cooler with a return of
onshore flow Friday through the weekend.

&&

.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...

Update: The forecast in the short term has remained the same, with
increasing Santa Ana Conditions from Wednesday into Thursday. The
winds still look to be generally below the threshold of Wind
Advisory, with the strongest gusts being located across the
mountains of San Diego County, where gusts may occasionally over 50
mph through some of the passes as some of the high red guidance
suggests. This will continued to be mentored in the upcoming days
for possible issuance, as latest models have been trending to
these winds being slightly stronger. After that, an upper level
low transitioning over the region after a rex block cuts off the
low to the south. This may allow for some showers, or even
possibly a thunderstorm or two, to be possible during the
afternoon on Friday. This could possibly hang around into Saturday
as well, depending on where this upper level feature decides to
propagate. There is also a slight better chance of the marine
layer and fog penetrating into some of the coastal communities
overnight. As offshore winds return by Wednesday, this should help
mitigate the threat of foggy conditions along the coast as winds
become more lightly offshore. There also appears to be a lot more
indication of the broad area of troughing well upstream to begin
to influence the region with much cooler and wetter conditions by
the beginning next week as a series of troughs approach the
region.

Previous discussion submitted at 407 PM:

Mostly sunny this afternoon with a few high clouds. Temperatures
are generally lower than yesterday with some coastal and valley
locations as much as 10-15 degrees lower than at this time
yesterday. Surface pressure gradients are trending weaker offshore
with -3.9 mb SAN-TPH. A weak sea breeze has developed west of the
mtns.

From previous forecast...
High-resolution models indicate a return of low clouds and fog to
the coastal areas tonight into Tuesday morning. This is in spite
of the surface pressure gradient trending stronger offshore during
the next 24 hours as the upper level trough moves east and a sfc
high moves into the Great Basin. The developing offshore flow will
likely not be strong enough to push the marine layer clouds/fog
offshore tonight/Tue morning. Wind gusts below the passes and on
the coastal slopes will only peak at around 25-30 mph. Tuesday and
Wednesday will be warmer as a Rex Block develops over the west
coast, with an upper level low centered off the coast of central
Baja and an upper high centered over the Bay Area. This pattern
will provide easterly flow aloft over SoCal, enhancing the
offshore flow on Wednesday and Thursday. Tuesday and Wednesday
will likely be the warmest days with high temps 15-20 degrees
above normal for the coastal areas and valleys and around 10-15
degrees above normal in the mountains and deserts. The national
Blend of Models indicates a 25-45 percent chance of 90+ degrees on
Wed for portions of inland OC. This drops to about 15 percent on
Thu.

Temperatures begin to trend lower on Thu as the upper high shifts
east in response to a low pressure trough approaching from the
West. This trough will merge with the low to the south as it moves
southeast over the region. The evolution of these systems remains
very uncertain due to the spread among model solutions. Some
previous solutions were indicating very small chances for
precipitation Fri-Sat. Current solutions are mostly dry but the
possibility of light precip on those days can't be eliminated. We
can say with reasonable confidence that Fri-Sat will be cooler
with increasing marine layer clouds as onshore flow returns.

A transient ridge will likely bring fair weather and a minor
warmup on Sunday before a more significant low pressure trough
moves in on Monday. This has the potential to bring precip to
SoCal, mainly from the mtns westward. A majority of ensemble
members across model platform indicate chances for precip on
Monday. The NBM indicates about a 45 percent chance of measurable
precip.

.AVIATION...
030330...Coast...Patchy low clouds based 400-700 ft MSL with vis 3-6
SM in BR have formed along parts of the coast this evening. Clouds
will become more widespread along the coast through 10Z and spread
inland up to 5-10 miles overnight. 70% chance for CIGs at KSAN/KSNA
and 45% chance at KCRQ by 09Z. Bases likely to lower to 200-500 ft
MSL overnight with areas of vis 1/4-2 SM, especially over coastal
highlands, with a 50-60% chance for VIS < 1/2 SM at all coastal
sites overnight. Low clouds and FG scatter out 14-17Z Tue, followed
by widespread VFR conditions.

Elsewhere...VFR conditions with FEW-SCT high clouds through Tuesday
afternoon.

&&

.MARINE...
Patchy fog with local visibility under 1 nautical mile expected
through Tuesday morning. Otherwise, no hazardous marine conditions
are expected through Friday.

&&

.BEACHES...
Surf of 3 to 6 feet with sets to 8 feet peaks today then gradually
diminishes Tuesday. A higher than average tide Tuesday morning will
combine with the elevated surf to produce minor tidal overflow and
flooding along with strong rip currents and hazardous swimming
conditions through Tuesday morning, most likely in San Diego County.
Check the Coastal Hazard Message for details on these hazards.

&&

.SKYWARN...
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

&&

.SGX WATCHES/WARNINGS/ADVISORIES...
CA...Coastal Flood Advisory until 10 AM PST Tuesday for San Diego
     County Coastal Areas.

     Beach Hazards Statement until 9 PM PST this evening for Orange
     County Coastal Areas.
