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 Feb 9, 10:00 AM PST, 3 hours 23 minutes earlier.

Area forecast discussion, Feb 9, 10:00 AM PST, 3 hours 23 minutes before
Area Forecast Discussion
National Weather Service San Diego CA
1000 AM PST Fri Feb 9 2024

.SYNOPSIS...
Scattered showers will continue from the coast to the mountains
today, decreasing tonight and ending by early Saturday. Dry weather
will prevail with a slow warming trend this weekend and most of next
week. with high temperatures warming to near average for the middle
of next week. The flow will turn briefly offshore with gusty north
winds to 35 to 45 mph Saturday morning along and below the coastal
slopes of the San Bernardino County mountains. A wetter pattern may
return the weekend of February 17-18.

&&

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

Scattered showers continued at mid-morning with greatest areal
coverage in San Diego County and far southern Orange County. Hourly
rainfall rates have been less than 0.10". Otherwise, mostly cloudy
skies continued from the mountains west to the coast, with partly
cloudy conditions in the deserts. It will be another chilly day with
highs mostly in the mid 50s to lower 60s at lower elevations. One
last wave will dive south tonight on the west side of the deep
western US trough to keep the scattered showers going overnight,
especially San Diego County, though HREF does show some activity in
the San Bernardino Mountains too with hourly probabilities of
measurable precip reaching 60% at 3 AM there.

The high pressure ridge off the West Coast will move into the
Western US, though with occasional shortwaves moving through to
moderate the strength of the ridge. Thus, the temperature increase
will be gradual, though with temperatures probably just making it to
near normal by mid-week, even though some MOS values, including from
the ensemble ENS, have above normal temperatures inland the second
half of next week. Low temperatures could be a concern Saturday and
Sunday nights in the valleys with guidance suggesting temperatures
near or slightly below freezing in coldest locations.  NBM has about
a 50-60 percent chance of temperatures at 4 AM Sunday at/below 32 in
from Temecula to Perris that typically gets cold during clear calm
winter nights. A frost advisory will likely be needed Saturday and
Sunday nights in the valleys, though San Diego County's risk area is
smaller, mostly near Ramona and the San Pasqual Valley. Also, some
north/northeast winds will occur mainly in San Bernardino County
Saturday morning, but high-resolution models indicate gusts
remaining below 45 MPH in windiest locations, with winds dropping
Saturday afternoon.

Ensemble solutions show a deep trough next weekend (17-18 Feb) off
the coast, with some variability in the timing/distance from the
coast. We will likely receive at least some precipitation, and some
ensembles indicate 70+ 24-hour probabilities of measurable precip
and even a 30+ 24-hour probability of exceeding 1 inch in some areas
from the mountains west to the coast, with hints of an atmospheric
river.
