What forecasters said that day
The local office's own words before this heat 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 heat advisory went out at Sep 3, 9:35 AM PDT, 3 hours 43 minutes earlier.
Area forecast discussion, Sep 3, 9:35 AM PDT, 3 hours 43 minutes before
Area Forecast Discussion
National Weather Service San Diego CA
935 AM PDT Fri Sep 3 2021
.SYNOPSIS...
High pressure will build into SoCal this weekend, bringing hot
temperatures to inland areas. The marine layer will become
shallower and less extensive this weekend. Monsoon thunderstorm
chances return mid to late next week to the mountains and deserts.
A gradual cooling trend is in store for inland areas mid to late
next week.
&&
.DISCUSSION...FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE...
SAN DIEGO...WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO
COUNTIES...
At 9 AM, visible satellite showed low clouds extending into
portions of inland Orange County and the San Diego valleys, with
all other areas clear. Low clouds were less extensive last night,
only reaching into portions of the San Diego valleys and not quite
making it into the Inland Empire. Low clouds will become shallower
and less extensive this weekend, mainly staying confined to
coastal areas and far western valleys.
A ridge of high pressure over the central U.S will push westward
this weekend and build into California. A 594 DM high will center
itself over central California and central Nevada by Sunday. This
will bring hot temperatures to inland areas this weekend, with
the peak of the heat on Sunday. Highs in the Inland Empire will
generally be 100-105 degrees Saturday through Monday, though some
of the hotter spots could be a couple of degrees higher,
especially on Sunday. In the lower deserts, temperatures look to
be around 110-113 degrees. The High Deserts will be around 100
degrees. The mountains below 5000 feet will also see much warmer
than normal temperatures, with highs near 90 degrees. With a
continued marine influence, the coast and the San Diego valleys
should largely escape the heat, though some 90s can be expected in
the far inland San Diego valleys and inland Orange County. Heat
products will be considered with the afternoon forecast package.
The forecast challenge today is the large difference between model
solutions on how hot it will be this weekend. The ECMWF model and
its ensembles are showing the highest temperatures this weekend
out of all the models, while GFS and NBM solutions are quite a bit
lower than the ECMWF. Given the large differences in temperatures
between the model suites, high temperatures with the afternoon
forecast package will likely be somewhere in the middle of these
solutions, with a slight lean towards the ECMWF.
With the heat building in, combined with dry fuels and diurnal
winds, a few hours of elevated fire weather conditions are
possible for inland areas each afternoon this weekend and early
next week.
The aforementioned high pressure will push a north a bit on
Monday, which should bring temperatures down by a couple of
degrees, though it will still be hot for inland areas.
The high pressure starts to break down and push east starting
around Tuesday next week, which will result in a gradual cooling
trend for inland areas through the end of the week, though the
heat may hang around in the lower deserts until Wednesday. With
the high pressure pushing east, this puts SoCal in a good position
to welcome monsoon moisture back into the area mid next week.
Current model guidance suggests thunderstorm chances returning to
the mountains and deserts around Wednesday of next week and
continuing through at least Friday.

.AVIATION...
031610Z...Coast/Valleys...Low clouds with bases 1300-1700 ft MSL and
tops to 2300 ft MSL now beginning to clear at the inland edges.
Expect clearing to the coast around 18Z. Patchy low clouds
redeveloping after 01Z Saturday and spreading 10-15 mi inland
overnight, mainly in San Diego County. Clouds likely to vary between
SCT and BKN tonight through Saturday morning, with bases lowering to
around 1000-1500 ft MSL. Local vis below 3 miles on elevated coastal
terrain after 05Z Saturday.
Mountains/Deserts...Mostly clear skies with unrestricted vis through
Saturday.
&&
.MARINE...
No hazardous marine conditions are expected through Wednesday.
&&
.BEACHES...
A south-southwest swell (from 200 degrees) of 2-3 feet with a period
of 16-18 seconds will arrive at Southern California beaches late
Saturday afternoon. This swell will generate surf of 3 to 5 feet
with sets to 6 ft at Orange County beaches Sunday and Monday, along
with a high rip current risk. In San Diego County, the surf will be
mostly 3-4 ft with a moderate rip current risk. See the Beach
Hazards Statement for more information. Swell and surf will begin to
subside Tuesday.
