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 4, 9:50 AM PST, 3 hours 10 minutes earlier.

Area forecast discussion, Jan 4, 9:50 AM PST, 3 hours 10 minutes before
Area Forecast Discussion
National Weather Service San Diego CA
950 AM PST Sat Jan 4 2020

.SYNOPSIS...
High pressure aloft will bring generally clear skies and mild
weather this weekend. A Santa Ana pattern develops Sunday night
bringing gusty northeast winds and warm days Monday and Tuesday. The
weather turns cooler Wednesday and Thursday as a trough of low
pressure deepens over the West Coast. This trough will bring cool
weather and a chance of showers next Sunday.

&&

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

The 500 mb ridge aloft over the Southwest is in the process of
getting flattened by a trough of low pressure moving ashore over the
Pacific Northwest. The trough is too far north to have much impact
on the weather here in SoCal, and today will be another sunny, mild
day with light winds. The pressure gradients turn a little more
strongly onshore tonight and Sunday which will translate to a little
more marine layer cloud coverage near the coast late tonight and a
few degrees of cooling west of the mountains Sunday. High
temperatures in the mountains and deserts will be relatively
unchanged from today to tomorrow.

Sunday night and Monday will be quite different as we brace for a
moderately strong Santa Ana event. A High Wind Watch is in effect
from Sunday evening through Tuesday morning. Blustery offshore
northerly winds will initially surface late Sunday afternoon in San
Bernardino County Mountains as a 1038 mb surface high pressure
builds over Oregon and northern Nevada. This north-south gradient
strengthens through Sunday evening, and a surge of strong north-
northeast winds will funnel through the Cajon Pass into the Inland
Empire. Strong winds will also impact the Santa Ana Mountains.

The SAN-TPH offshore pressure gradient is forecast to be about
.5 mb stronger today (-13.9 mb) compared to yesterday (-13.4 mb).
Model guidance suggests peak gusts of 60-70 mph at Fremont Canyon
and Pleasants Peak in the Santa Ana Mountains by Monday morning.
Gusts elsewhere (where people actually live) will range from 40 to
55 mph. Farther south in San Diego County the winds will be lighter
in a relative sense Sunday evening, but will increase Sunday night
into Monday morning as the surface high builds over Utah.

A secondary, weaker surge of Santa Ana winds will surface Monday
night into Tuesday morning. The gradients will be oriented more east-
northeast with the strongest winds farther south into San Diego
County.

Downslope warming to the coast on Monday will raise high
temperatures into the mid to upper 70s in the coastal zones, higher
than the max temperature in Palm Springs (low 70s). Tuesday will be
another warm day with weak offshore flow slowly transitioning to
onshore flow in the afternoon.

A progressively cooler pattern will develop Wednesday through Sunday
when a trough pattern sets up along the West Coast. The first wave
arriving Thursday could bring a few showers, followed by a second
stronger wave for even cooler weather and a better chance for
precipitation next Sunday.

.AVIATION...
041650Z...Coast...Scattered high clouds at/above 20,000 ft MSL
throughout the day. Low clouds and fog lingering off the coast of
KSAN may bring the airport a period of BKN low clouds between 05/10Z-
05/16Z with bases 800-1200 feet MSL. Risk of BKN low clouds at KSAN
Saturday night/Sunday morning is moderate to high, so confidence in
BKN clouds is also moderate to high at KSAN. A brief period of BKN
low clouds at KCRQ is also possible. Visibilities locally below 3 sm
in fog at times mesa areas from 05/12Z-05/16Z Sunday morning. KSNA
will likely only have FEW-SCT low clouds overnight, Any low clouds
that form will scatter out around 05/16Z Sunday morning.

Valleys/Mountains/Deserts...Mostly clear with unrestricted vis
through today.

&&

.MARINE...
No hazardous marine conditions are expected through Sunday. A slight
bump up in swell is expected Sunday into early Monday with combined
seas of 6-9 feet.

&&

.BEACHES...
Elevated surf of 3-5 feet and a high rip current risk will continue
through the weekend. Calmer conditions expected into the work week.
