Area Forecast Discussion
National Weather Service San Diego CA
945 AM PST Wed Jan 25 2017

.SYNOPSIS...
Strong high pressure building over the Great Basin will bring clear,
cool weather this week. It will also produce strong and potentially
damaging offshore winds Friday and Saturday. Clear with lighter
winds and warmer days Sunday and Monday.

&&

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

It was a cold start to the day with valley lows in the 30s, and
mountain lows in the teens and 20s. One of the coldest spots was Big
Bear Airport with a low of -5 due to clear skies, light winds and
and a fresh snowpack. Sunny and cool today, with another clear, cold
and frosty night tonight.

The rain and snow have passed and we will be in a dry pattern
through early next week with a high amplitude ridge over the Pacific
building over the West Coast through the weekend. At the same time,a
trough from Canada will move south over the intermountain West.
Gradient winds between the building high and this upper trough will
set the stage for a strong Santa Ana wind event here is SoCal Friday
and Saturday.

By Friday morning a 1047 mb surface high will be over Nevada
resulting in 15+ mb of offshore pressure gradients. The WRF and
CANSAC models project surface winds of 40-50 mph in and through the
mountain passes into the inland valleys and Orange County. This will
be a strong and potentially damaging wind event with gusts in excess
of 70 mph in the wind prone Santa Ana areas. The cold northerly flow
will keep temperatures on the cool side, especially in the mountains
and deserts. Downslope flow to the coast along will result in slight
warming there. Nights will be clear and cold.

The offshore winds will be weaker Sunday and Monday and it will be
warmer, especially west of the mountains where highs will be in the
70s. The high pressure ridge breaks down midweek ahead of a Pacific
trough that will move into the West Coast. This will start a cooling
trend as we head into February, and it could open the door for our
next precipitation.

&&

.AVIATION...
251700Z...Mostly clear through Thursday morning. Chance of fog
Thursday morning in low-lying areas of the valleys (KRNM/KCNO) with
vis 1 SM or less for a few hours before sunrise.

&&

.MARINE...
Offshore (Northeast) wind gusts of 20-25 kt are possible over
portions of the waters Friday and Saturday. Otherwise, no hazardous
marine weather is expected through Sunday.

&&

.BEACHES...
Surf has lowered overnight, but will remain elevated today. The High
Surf Advisory was allowed to expire at 9 AM.

A new long period west-northwest swell from 290 degrees will arrive
Thursday, peak Friday at 8 ft/18 seconds, and then lower during the
weekend. This swell will bring near high surf conditions (around 4-7
ft) on Friday along with strong rip currents.

&&

.SKYWARN...
Skywarn activation is not requested. However weather spotters are
encouraged to report significant weather conditions.

&&

.SGX WATCHES/WARNINGS/ADVISORIES...

PZ...None.
