Area Forecast Discussion
National Weather Service San Diego CA
915 PM PST Fri Dec 16 2016

.SYNOPSIS...
Scattered light showers will continue overnight before ending early
Saturday morning as the strong trough that brought soaking rains
west of the mountains moves east. Strong west winds will continue
from the mountains into the deserts. Cool and dry Saturday, then
slow warming Sunday and Monday with weak to locally moderate
offshore winds. Fair and warmer next week with continued offshore
flow.

&&

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

The KNKX radar in San Diego is down. Techs are working on it.

A sharp trough with a potent vort max is generating renewed
convection as it races across SoCal this evening. Light snow was
reported in Hesperia (el 3500 ft) at 8 pm. A band of light to
moderate snow is likely in the mountains tonight with up an inch or
two of accumulation possible above 5000 feet. Light showers are also
possible west of the mountains with greatest chances in the inland
valleys and foothills.

Very strong winds will continue in the mountains and deserts
tonight. A peak gust of 89 mph was recorded at Burns Canyon at 551
PM. The Thermal Airport had a gust to 58 mph at 725 PM. A few downed
trees have been reported in the mountains, and structural damage
(partial roof torn off) was reported by a SKYWARN weather spotters
at Lucerne Valley. A High Wind Warning remains in effect for the
mountains and deserts through 2 AM Saturday.

The trough axis passes late tonight followed by trailing north flow
which will make Saturday feel colder than today. Gusty northerly
winds in the SBD mtn will filter through the Cajon Pass into the IE
tomorrow. The gusty winds shift northeast Sunday and Monday and will
be more widespread in the mtns, foothills and valleys as a weak to
moderate Santa Ana pattern develops. Expect winds of 15 to 30 mph in
the wind prone areas with gusts of 40 to 50 mph in the passes and
foothills. Downslope flow will bring warming Sunday to the coastal
and valleys zones, but there will not much temperature change in the
mtns and deserts. Cold nights are in store for the mountains and
high deserts this weekend.

Warmer Tuesday and Wednesday with dry northwest flow aloft. The long
range models are waffling back and forth between ridging and
troughing over the Christmas holiday weekend. The EC projects a deep
trough and a greater chance for precip, while the GFS is dry with a
building ridge over the Southwest.

&&

.AVIATION...
170500Z...Sct -SHRA will move E/SE over San Bernardino and Riverside
Counties with -SHSN above 3500 ft MSL, with showers mostly ending by

through around 09Z in most areas from the mountains west to the
coast with higher terrain obscured. Mostly clear skies will prevail
by about 12Z Sat, though patchy ground fog with vis below 1 mile
will be possible in the valleys 10Z-16Z Sat, including VCNTY KRIV,
Gave and KRNM.

W to NW surface winds will continue to gust 35-45 knots in parts of
the mountains and deserts through 09Z with some rotors VCNTY KPSP.
