Area Forecast Discussion
National Weather Service San Diego CA
310 AM PST Tue Mar 3 2026

.SYNOPSIS...
Warmer today for the coast to the mountains with weaker winds for
inland areas. A low pressure system from the northwest will bring
much cooler high temperatures for the mountains and deserts on
Thursday with stronger and gusty west to northwest winds for the
mountains and deserts for Wednesday night and Thursday. Then
warmer for Friday into the weekend with offshore lower-level
flow and strengthening east to northeast winds. Moisture from the
east could bring some showers for Sunday and Monday.

&&

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

.SHORT TERM (Today through Thursday)...
The low pressure system that brought stronger onshore flow to
southern California on Monday spread cooling inland and brought
stronger and gusty southwest to west winds to the mountains and
deserts. The late afternoon NKX sounding showed multiple weak
inversions below 4500 feet. Satellite imagery shows low clouds
over portions of the coastal waters and portions of the coast and
western valleys. The greatest coverage over land areas as of 2:30
AM was over the western valleys in San Diego County.

As this low pressure system moves eastward and inland today, high
temperatures from the coast to the mountains will warm, by around
5 degrees to locally degrees for the inland valleys, inland
Orange County, and the lower elevations of the mountains. With the
warming, high temperatures for today will range from the mid to
upper 60s near the coast to the mid 70s to lower 80s for the
Inland Empire. The deserts will be a few degrees cooler with high
temperatures for the lower deserts in the mid to upper 80s.

An approaching low pressure system from the northwest will begin
to spread cooling inland on Wednesday with high temperatures for
the coast and valleys a few degrees cooler than today. Much
greater cooling will spread inland on Thursday with high
temperatures 10 to locally 15 degrees cooler for the deserts onto
the desert slopes of the mountains. There will be stronger west to
northwest winds for the mountains and deserts for Wednesday night
into Thursday morning with gusts to 40 to 50 mph and isolated
gusts to 65 mph.

&&

.LONG TERM (Friday through Monday)...
Friday is expected to be warmer with winds becoming offshore. For
the weekend into early next week, a closed low pressure system is
expected to be over Baja, southern California, and the adjacent
eastern Pacific with differences in the placement of the center of
this upper low. Current guidance has the greatest warming west of
the mountains on Friday and Saturday with east to northeast winds
strengthening along and below the coastal slopes of the mountains.
By Sunday and Monday, depending on the placement of the upper
low, it could begin to entrain some moisture from the south and
southeast with increasing clouds and a slight chance of showers.

&&

.AVIATION...
031030Z....Coast/ western valleys...Areas of low clouds will
continue to expand in coverage through 15Z. Bases will be 1500-2200
feet MSL, with local vis restrictions on higher coastal terrain and
inland. Scatter out 16-18Z. Areas of low clouds will redevelop after
04Z overnight into Wednesday more confined to coastal areas. Bases
a little lower, around 500-1500 feet MSL.

Otherwise...VFR conditions: clear today and some high clouds tonight.

&&

.MARINE...
Stronger northwest winds return late Wednesday into Thursday in the
outer waters, producing choppy conditions that may become hazardous.
Otherwise, no hazardous marine conditions are expected through
Saturday.

&&

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

&&

.SGX WATCHES/WARNINGS/ADVISORIES...
CA...None.
PZ...None.
