AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
337 AM PST WED DEC 23 2015

.SYNOPSIS...
GUSTY WEST WINDS AND OCCASIONAL SHOWERS WILL CONTINUE ACROSS
PORTIONS OF THE REGION THIS MORNING. DRY WEATHER WILL RETURN LATE
TODAY THROUGH EARLY THURSDAY....THEN A LOW PRESSURE TROUGH WILL
BRING LOWER TEMPERATURES AND A CHANCE OF RAIN AND SNOW SHOWERS
FOR LATE CHRISTMAS EVE THROUGH CHRISTMAS MORNING...WITH QUITE LOW
SNOW LEVELS PERHAPS DOWN TO AROUND 3000 FEET. BELOW NORMAL HIGH
TEMPERATURES AND VERY STRONG GUSTY WEST WINDS IN THE MOUNTAINS
AND DESERTS ARE EXPECTED LATE CHRISTMAS EVE AND ON CHRISTMAS...AS
WELL. MODERATE TO STRONG OFFSHORE WINDS FOR THE WEEKEND...WITH A
SLIGHT WARM UP TO NEAR OR JUST BELOW NORMAL HIGH TEMPERATURES FOR
SUNDAY THROUGH TUESDAY. AREAS OF FROST WILL BE POSSIBLE FOR INLAND
AREAS SATURDAY AND SUNDAY MORNINGS.

&&

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

A VERY WEAK SHORTWAVE WILL PASS OVER SOUTHERN CALIFORNIA THIS
MORNING. VERY STRONG UPPER LEVEL FLOW IS PASSING OVER THE
TEHACHAPI MOUNTAINS WITH ABUNDANT MOUNTAIN WAVE CLOUDS SHOWING UP
ON SATELLITE LOOPS ATTM. STRONG WINDS NOTED IN THE HIGH DESERTS
AND OUR NORTHERN MOUNTAINS...WHERE A WIND ADVISORY REMAINS IN
PLACE FOR THIS MORNING...THROUGH 10 AM. ABUNDANT BUT SHALLOW LOW
LEVEL MOISTURE REMAINS IN PLACE WITH THE RECENT SAN DIEGO
SOUNDINGS SHOWING JUST OVER 1 INCH PWATS...AND MOST OF THAT IS
BELOW 700 MB. OCCASIONAL SHOWERS WITH VERY HIGH EFFICIENCY WILL
CONTINUE THIS MORNING...MAINLY IN SAN DIEGO COUNTY. THESE SHOWERS
WILL COME TO AN END BY AROUND NOON AS THE PREDOMINANT FLOW BECOMES
LESS CYCLONIC AND WITH LESS PVA ROTATING THROUGH THE AREA.

FOR TONIGHT AND THURSDAY...PREDOMINATELY WESTERLY FLOW WILL
PERSIST OVER OUR AREA. WEAK UPPER LEVEL IMPULSE EARLY THURSDAY
MORNING BUT LIMITED MOISTURE SHOULD KEEP THE RAIN AT BAY DURING
THAT TIME PERIOD. JUST DON'T SEE QUITE ENOUGH FORCING OR MOISTURE
AT THIS TIME TO ADD POPS INTO THE FORECAST.

FOR THURSDAY EVENING THROUGH FRIDAY MORNING...A REAL ROLLER
COASTER RIDE FOR OUR REGION...AS A STRONG UPPER LEVEL TROUGH WILL
CARVE OUT A DEEPER AND COLDER LOW DROPPING SOUTH THROUGH THE GREAT
BASIN AND INTO ARIZONA THROUGH SATURDAY. THIS SYSTEM WILL
INITIALLY BRING A GOOD CHANCE FOR RAIN AND SNOW SHOWERS ACROSS THE
HIGH DESERTS...MOUNTAINS...VALLEYS AND COAST. COLD AIR DROPPING
SOUTH THROUGH THE BASIN WILL DROP SNOW LEVELS DOWN TO POSSIBLY AS
LOW AS 3000 FEET BY CHRISTMAS ACROSS OUR MOUNTAINS AND THE HIGH
DESERT. HOWEVER MOISTURE IS ON THE LIMITED SIDE WITH THIS DEEP
TROUGH...SO ONLY AN INCH OR THREE WILL BE POSSIBLE ALONG THE
PASSES AND IN THE MOUNTAINS...AND MAYBE A DUSTING IN THE HIGH
DESERTS.

THE BIGGER STORY MAY BE THE VERY STRONG WESTERLY TO NORTHWESTERLY
WINDS THAT LOOK TO DEVELOP LATE CHRISTMAS EVE INTO CHRISTMAS
MORNING...ESPECIALLY FOR THE HIGH DESERTS AND THE PASSES AND
DESERT SLOPES OF THE MOUNTAINS. DUE TO THE POTENTIAL MAGNITUDE OF
THE WINDS...WITH GUSTS POSSIBLY EXCEEDING 60 MPH...HAVE ISSUED A
HIGH WIND WATCH AT THIS TIME FOR LATE CHRISTMAS EVE THROUGH
CHRISTMAS MORNING. (FRIDAY 00Z-18Z) WINDS THROUGH THE FAVORED
PASSES AND ALONG THE DESERT SLOPES COULD REACH 70 TO 80 MPH.

VERY STRONG OFFSHORE FLOW WILL THEN DEVELOP ON SATURDAY AND
CONTINUE THROUGH SUNDAY AS THAT UPPER LEVEL COLD LOW DROPS SOUTH
THROUGH ARIZONA...BRINGING TRANSITORY RIDGING ACROSS
CALIFORNIA. SURFACE GRADIENTS AROUND 20 MB...POSSIBLY EVEN A BIT
HIGHER...ACROSS THE GREAT BASIN...SHOULD LEAD TO A PERIOD OF VERY
STRONG SANTA ANA WINDS SATURDAY INTO SUNDAY. MEANWHILE COLD AIR
WILL CONTINUE TO BE DRAINED INTO THE HIGH DESERTS...WITH OVERNIGHT
FROST IN THE VALLEYS AND POSSIBLY NEAR HARD FREEZE CONDITIONS FOR
THE HIGH DESERTS.

A SERIES OF WEAK TROUGHS WILL PASS THROUGH CALIFORNIA EARLY TO
MID NEXT WEEK. QUITE A BIT OF DISAGREEMENT CONTINUES IN THE MEDIUM
RANGE SOLUTIONS WITH REGARDS TO THE STRENGTH OF THESE
SYSTEMS...ALTHOUGH ADDITIONAL CHANCES FOR PRECIPITATION WILL BE
POSSIBLE AND MODEST SWINGS IN TEMPERATURES AS WELL.
