What forecasters said that day

The local office's own words before this wind advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS San Diego, CA wrote its last area forecast discussion before this wind advisory went out at Jan 13, 9:30 AM PST, 4 hours earlier.

Area forecast discussion, Jan 13, 9:30 AM PST, 4 hours before
Area Forecast Discussion
National Weather Service San Diego CA
930 AM PST Fri Jan 13 2023

.SYNOPSIS...
Today will be partly cloudy and mild with temperatures a little
above average in most areas. A storm approaching from the west
tonight will bring light rain to the area during the day Saturday,
which will become heavy at times in the mountains Saturday night.
Scattered showers will linger into Sunday. A second storm will bring
more rain and mountain snow Monday and Tuesday. Cool, dry weather is
forecast next Wednesday through Friday.

&&

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

Morning Update:

No significant updates were needed this morning. The high cloud
cover will keep temperatures from getting too warm today, with highs
around 70 west of the mountains, away from the beaches. Yesterday's
offshore surface pressure gradients shift back onshore today and the
winds will become westerly as a longwave trough over the Pacific
forces the fair-weather ridge eastward over the Rockies. Today will
be not too dissimilar from yesterday with scattered high clouds and
temperatures at or a little above average.

Previous Discussion (from 253 AM PST):

The Pacific trough presses inland across the CA through the weekend
bringing another round of rain and Sierra snow to northern and
central CA Saturday. On Saturday night the jet core digs south and
that is when Southern California will see another round of rain and
mountains snow. This will be another strong orographic rain maker on
the south facing slopes of the San Bernardino/San Gabriel mountains,
so much so that the Weather Prediction Center this morning expanded
their SLGT risk coverage of their Excessive Rainfall Outlook to
include the San Bernardino Mountains where 2-4" of rain is forecast.
Rain totals over the Santa Ana, San Jacinto and San Diego County
Mountains will range from 1-3". More rain on already saturated
grounds mean more mud, rock and debris flows in the mountains.

Coastal and Valley rain projections are quite variable, ranging from
0.25"-1.50, with generally higher amounts in Orange County, the
northwestern IE and some of the San Diego Valleys, and lowest
amounts in southwestern San Diego County. The high deserts will see
from 0.20"-0.40", and the lower deserts from 0.10"-0.25".

Snow levels starting out around 7500 feet Saturday morning will fall
to near 5,000 feet Sunday morning, changing the rain to snow in the
San Bernardino Mountains with several inches accumulating at resort
levels.

Sunday will be cold day with instability showers tapering off during
the afternoon, lingering longest over the mountains. But wait,
there's more! Yet another deep, moisture-laden trough will bring
more rain and mountain snow Sunday night and Monday. This will be a
colder storm with lower snow levels. A trailing shortwave will keep
instability showers across Southern California through Tuesday which
will be a much colder day with snow levels falling below 5,000 feet.

The trough edges east Tuesday night with dry, cool northwest flow
Wednesday through Friday keeping temperatures below average through
weeks end.

.AVIATION...
131630Z...Coast/Valleys/Mountains... SCT-BKN AOA 15000 ft MSL today.
Patchy low clouds possible after 03z Sat along the coast, spreading
inland after 08z Sat, with bases 1000-1500 FT MSL. BKN-OVC low to
mid level clouds expected through much of the day Sat, with variable
bases 1500-5000 ft MSL. Lower bases are expected in areas of
showers. Areas of vis reductions down to 1-3 SM in areas of showers
and where clouds intersect terrain. Rain showers possible after 15Z
Sat moving northwest to southeast, with more widespread rain, again
moving from northwest to southeast, after 00Z Sun. South-southwest
winds are expected to prevail for much of the day Sat, becoming
gusty late in the day Sat.

Deserts... SCT-BKN high clouds AOA 20000 ft MSL today.

&&

.MARINE...
A large long-period west swell will generate combined seas of 7-11
feet through Saturday, with the highest occurring south of San
Clemente Island. Southwest to west winds of 15-20 kt with gusts to
25 kt and rough seas will develop Saturday evening and overnight.
Seas and winds decrease somewhat Sunday evening, then increase again
Monday and Tuesday as another storm as well as another large west
swell moves in. Conditions will be hazardous for small craft at
times through Tuesday.

&&

.BEACHES...
A long-period west swell from 280 degrees is on track to arrive
today. Surf of 8-12 feet is expected in San Diego County and 6-10
feet in Orange County through Saturday. Surf may be large enough to
produce minor coastal flooding during high tides, especially in San
Diego County. Coastal Flood and High Surf Advisories have been
issued and can be referenced for more details. A slight decrease in
surf is expected Sunday and Monday. Another large west swell is
forecast to arrive early Tuesday and may produce additional high
surf.
