AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
200 PM PST SUN DEC 13 2015

.SYNOPSIS... A LOW PRESSURE TROUGH WILL MOVE THROUGH THE AREA
TONIGHT AND BRING A PERIOD OF RAIN TO MOST AREAS ALONG WITH AREAS OF
STRONG GUSTY WINDS. SOME SNOW WILL FALL AT HIGHER ELEVATIONS. THE
TROUGH WILL MOVE INLAND MONDAY AND TUESDAY...AND WEAK OFFSHORE FLOW
WILL DEVELOP HERE TO BRING A RETURN TO FAIR WEATHER...BUT WITH BELOW
NORMAL TEMPERATURES ALONG WITH AREAS OF FROST IN THE VALLEYS AT
NIGHT. A WARMING TREND WILL OCCUR THE SECOND HALF OF THE WEEK. A
PACIFIC SYSTEM COULD BRING PRECIPITATION EARLY NEXT WEEK.

&&

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

CLOUDS HAVE BEEN DEVELOPING OVER MOST AREAS THIS AFTERNOON AHEAD OF
THE NEXT SYSTEM WHICH IS BRINGING RAINFALL AS FAR SOUTH AS SANTA
BARBARA COUNTY...AND WINDY CONDITIONS TO PARTS OF CENTRAL/NORTHERN
CALIFORNIA. A WELL-DEFINED FRONT WITH STRONG SURFACE WINDS LIES OFF
THE SAN LUIS OBISPO COUNTY COAST AND WILL MOVE RAPIDLY PAST POINT
CONCEPTION LATE THIS AFTERNOON AND NEAR SAN DIEGO BY LATE EVENING.
TIME-HEIGHT HUMIDITY CROSS-SECTIONS SHOW A 2-3 HOUR PERIOD WITH THE
FRONT WHEN THE NEAR-SATURATED LAYER EXTENDS FROM JUST ABOVE THE
SURFACE TO A LITTLE OVER 700 MB...BUT WITH MUCH DRIER CONDITIONS
ABOVE 850 MB BOTH BEFORE AND AFTER THE FRONTAL PASSAGE. HENCE...IT
LOOKS LIKE A QUICK SHOT OF RAIN THIS EVENING...WITH TIMING RANGING
FROM 6-9 PM OVER ORANGE COUNTY/SOUTHWESTERN SAN BERNARDINO COUNTY TO
9 PM-MIDNIGHT OVER SAN DIEGO COUNTY. PRECIP AMOUNTS SHOULD GENERALLY
BE AROUND ONE-QUARTER INCH WEST OF THE MOUNTAINS...BUT SOME MOUNTAIN
LOCATIONS COULD HAVE ONE-HALF TO LOCALLY ONE INCH OF RAIN. SNOW
LEVELS WILL FALL WITH THE FRONT TO AROUND 4500-5000 FEET...WITH
MAINLY 2-5 INCHES ABOVE 5000 FEET IN THE SAN BERNARDINO/RIVERSIDE
COUNTY MOUNTAINS. WITH RATHER TIGHT HEIGHT/TEMPERATURE GRADIENTS
ALOFT...WINDS WILL BE FAIRLY STRONG IN THE MOUNTAINS/DESERTS WITH
LOCAL GUSTS IN THE 60-70 MPH RANGE ON THE DESERT SLOPES AND NEAR
GORGONIO PASS. WE HAVE UPGRADED THE WIND ADVISORY TO A HIGH WIND
WARNING TO SOME OF THE ZONES FOR TONIGHT. MODELS SHOW A PERIOD OF
STRONG WEST WINDS BEHIND THE FRONT OVER THE COASTAL WATERS...AND
SOME OF THAT WIND WILL REACH THE IMMEDIATE COAST LATE TONIGHT WITH
GUSTS LOCALLY AROUND 40 MPH THERE MAINLY 11 PM-4 AM. AFTER THE
SYSTEM PASSES TO THE EAST MONDAY AND THE GRADIENTS WEAKEN...WINDS
WILL DECREASE AND THE CLOUDS WILL MOSTLY DIMINISH. IT SHOULD BE
QUITE COLD MONDAY AND TUESDAY NIGHTS...WITH AREAS OF FROST IN THE
VALLEYS AND POSSIBLY THE LOWER DESERTS...AS 850MB TEMPS WILL BE NEAR
0 C...AND WINDS WILL BE LIGHT IN LOW-LYING AREAS. THE WEAK OFFSHORE
FLOW FOR TUE/WED SHOULD RESULT IN LOCAL BREEZY CONDITIONS
THROUGH/BELOW PASSES/CANYONS...BUT WINDS SHOULD BE BELOW WIND
ADVISORY STRENGTH WITH GUSTS MOSTLY 30-35 MPH.

AN EAST-PACIFIC HIGH PRESSURE RIDGE SHOULD MOVE THROUGH CALIFORNIA
AND BRING FAIR AND WARMER WEATHER THE SECOND HALF OF THE WEEK...THEN
A TROUGH COULD BE DEEP ENOUGH TO BRING PRECIPITATION EARLY NEXT
WEEK. ECMWF IS SLOWER BUT DEEPER WITH THE TROUGH THAN THE GFS...AND
TYPICALLY THE SLOWER MODEL 7-8 DAYS IN THE FUTURE IS BETTER WITH
TIMING. I HAVE INTRODUCED A 30-40 PERCENT CHANCE OF PRECIPITATION
FOR MOST AREAS FOR SUNDAY IN THE AFTERNOON FORECAST.

.AVIATION...
