AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN DIEGO CA
1258 AM PST WED DEC 19 2012

.SYNOPSIS...
VARIABLE HIGH CLOUDS TONIGHT WITH A DRYING TREND. GUSTY OFFSHORE
WINDS WILL DEVELOP BY EARLY MORNING AND CONTINUE THROUGH THIS
AFTERNOON. DRY AND SLIGHTLY WARMER CONDITIONS WILL PREVAIL THE
NEXT FEW DAYS...WITH LOW OVERNIGHT TEMPERATURES AND AREAS OF
FROST POSSIBLE. ANOTHER SYSTEM WILL THEN BRING ANOTHER CHANCE OF
PRECIPITATION TO THE AREA LATE SATURDAY THROUGH MONDAY.

&&

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

SATELLITE IMAGERY SHOWS MOSTLY CLEAR SKIES TONIGHT...EXCEPT FOR
SOME HIGH CLOUDS STREAMING ACROSS THE REGION FROM THE NORTH.
CONDITIONS ARE QUICKLY DRYING WITH THE NORTHERLY FLOW INCREASING.

FROM PREVIOUS DISCUSSION...THE GUSTY WEST TO NORTHWEST WINDS ARE
WEAKENING BEFORE BECOMING NORTH AND NORTHEASTERLY BY EARLY THIS
MORNING. THESE WINDS WILL INCREASE ONCE AGAIN...WHICH SHOULD HELP
KEEP TEMPERATURES UP A LITTLE. HOWEVER...SOME OF THE WIND
SHELTERED LOCATIONS WILL SEE TEMPERATURES FALL TO NEAR OR BELOW
FREEZING EVEN AT LOWER ELEVATIONS...WITH SOME FROSTY CONDITIONS
POSSIBLE. AREAS OF FROST WILL BE MORE OF AN ISSUE TOMORROW NIGHT
THOUGH...AS WINDS WEAKEN ACROSS THE REGION. OTHERWISE...EXPECT A
GRADUAL WARMING TREND OVER THE NEXT SEVERAL DAYS...AS WEAK RIDGING
DEVELOPS OVER SOUTHERN CALIFORNIA.

ANOTHER LOW PRESSURE SYSTEM WILL THEN MOVE INTO THE WEST COAST
LATE SATURDAY NIGHT AND SUNDAY. THE MODELS ARE VARYING ON THE
TIMING AND AMOUNTS OF THE PRECIPITATION MAKING IT THIS FAR
SOUTH...BUT IT COULD BE AS EARLY AS SATURDAY NIGHT...ESPECIALLY
FOR ORANGE AND SAN BERNARDINO COUNTIES. HOWEVER...IT LOOKS LIKE
THE BRUNT OF THE MOISTURE WILL MOVE THROUGH THE REGION SOMETIME
BETWEEN SUNDAY AND MONDAY. SNOW LEVELS WILL NOT BE QUITE AS LOW
WITH THIS NEXT SYSTEM...BUT A DUSTING OF SNOW WILL BE POSSIBLE
ABOVE 6000 FEET. DRIER NORTHWESTERLY FLOW OR WEAK RIDGING WILL
THEN REBUILD EARLY NEXT WEEK...WITH SLIGHTLY WARMER CONDITIONS
RETURNING ONCE AGAIN.

&&

NORTHERLY AND START TO WEAKEN EARLY THIS MORNING...WITH SWELL AND
SEAS DIMINISHING THROUGH THE DAY.
