Area Forecast Discussion
National Weather Service San Diego CA
905 PM PST Wed Jan 25 2017

.SYNOPSIS...
Clear and cold again tonight with areas of frost in the valleys.
Strong high pressure building over the Great Basin will bring
gusty offshore winds Thursday night through Saturday, strongest in
the mountains and valleys. 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...

Clear skies and light winds will result in another cold night
tonight. Temperatures will fall into the upper 20s to lower 30s
in the valleys where a Frost Advisory has been issued. Mountain
lows will fall into the teens and 20s, with some single digit lows
in the higher elevations including Big Bear and Mt San Jacinto.
Thursday will be sunny but cool.

Offshore Wind Event Thursday Night through Saturday: On Thursday
night a trough from Canada will move south across the Great Basin,
and an upper ridge will strengthen over the eastern Pacific.
Gradient winds between the building high and the upper trough
will increase Thursday night, and a period of strong Santa Ana
winds is forecast Thursday night through Friday. The strongest
winds will surface Friday morning with WRF and CANSAC models
forecasting surface winds of 40 to 50 mph in mountains...foothills
and into the Inland Empire. At that time a strong 1047 mb surface
high will be over Nevada, setting up offshore pressure gradients
of 15-20 mb. Winds gusts of 50-70 mph are possible in the wind
prone areas of the Mountains and Foothills Friday. A High Wind
Watch has been issued.

On Friday night and Saturday the upper support weakens and the
pressure gradients decrease too, so the winds will not be as
strong, probably only reaching Wind Advisory levels. The strongest
winds Friday night through Saturday will likely be in the
Riverside and San Diego County mountains and foothills as the
gradients become more east- west oriented.

The cold northerly flow will keep temperatures on the cool side,
especially in the mountains and deserts. Downslope flow to the
coast will result in slight warming there, mainly Saturday.
Nights will be clear and cold. The offshore winds will be weaker
Sunday and Monday and it will be warmer, especially in the coastal
and valley areas where the downslope warming will push highs into
the 70s.

The high pressure ridge breaks down midweek ahead of a Pacific
trough that will move into the West Coast. The main storm track
will be to our north, but the southern end of these weather
systems could bring periods of light rain to SoCal later next
week.

&&

.AVIATION...
260500Z...Mostly clear skies and unrestricted vis will prevail
through Thursday night. After 06Z Fri, NE surface winds 20-30 knots

the San Bernardino County Mountains, northern Inland Empire, San
Diego County Mountains and Santa Ana Mountains, including VCNTY
KONT, KCNO, KRAL and KSBD, along with strong up/downdrafts and LLWS.

&&

.MARINE...
Northeast wind gusts of 20-25 kt are possible over portions of the
coastal waters Friday through Saturday. Otherwise, no hazardous
marine weather is expected through Monday.

&&

.BEACHES...
A new long period west-northwest swell from 290 degrees will arrive
