.UPDATE...
STRONG HIGH PRESSURE EXITING THE SOUTHEAST UNITED STATES AND NOW
EXTENDING INTO THE WEST AND SOUTHWEST ATLANTIC WILL CONTINUE TO
BUILD FURTHER EAST INTO THE CENTRAL CARIBBEAN OVER THE NEXT FEW
DAYS. THIS IN TURN WILL TIGHTEN THE SURFACE PRESSURE GRADIENT ACROSS
THE REGION AND HELP PRODUCE FRESH TO STRONG NORTH TO NORTHEAST
TRADE WINDS. FRAGMENTS OF MOISTURE ALONG A WEAKENING FRONTAL
BOUNDARY/SHEAR LINE WILL CONTINUE TO SINK SOUTHWARDS OVER THE LOCAL
ISLANDS AND SURROUNDING WATERS OVERNIGHT THROUGH FRIDAY. AS A
RESULT...STILL EXPECT SURGES OF PASSING OVERNIGHT AND EARLY
MORNING SHOWERS ALONG THE NORTHERN HALF OR PUERTO RICO AND THE
NORTHERN VIRGIN ISLANDS...WITH CLOUDINESS AND PERIODS OF MOSTLY LIGHT
TO MODERATE QUICK PASSING SHOWERS EXPECTED TO SPREAD ACROSS THE
REMAINDER OF THE FORECAST AREA BY MID DAY THURSDAY. THEREAFTER...
A GRADUAL CLEARING AND BREEZY CONDITIONS STILL EXPECTED UNDER A
RATHER COOL AND STABLE AIR MASS. NO MAJOR CHANGES MADE TO THE
INHERITED FORECAST AT THIS TIME. DECIDED TO KEEP THE HIGH WIND
ADVISORY RUNNING FOR NOW...AS TRAILING EDGE OF FRONTAL ZONE STILL
ACROSS THE OFFSHORE ATLANTIC WITH WINDS OVER THAT AREA ALTHOUGH
NOT SUSTAINED...WERE FLUCTUATING BETWEEN 20 TO 23 KNOTS... BASED
ON SHIP REPORTS AND DATA FROM THE NORTHERN BUOY 41043...AS WELL AS
VAD WIND PROFILE DATA. FOR NOW WILL JUST HAVE TO CONTINUE TO
MONITOR SURFACE OBSERVATIONS AND REPORTS OVER THE NEXT FEW HOURS
AND MAKE ADJUSTMENTS AS NEEDED.

&&

.AVIATION...TEMPO MVFR CONDITIONS POSSIBLE ACROSS PR IN SHRA AS A
FRONTAL BOUNDARY MOVES IN FROM THE NORTH. OTHERWISE...PREVAILING VFR
CONDITIONS ARE EXPECTED ACROSS THE LOCAL ISLANDS DURING THE NEXT 24
HOURS. SURFACE WINDS ARE EXPECTED TO INCREASE TO NORTH NORTHEASTERLY
AT AT LEAST 15 KNOTS GUSTING TO 25 KNOTS OVERNIGHT...REMAINING
NORTHERLY AT ABOUT 15 TO 20 KNOTS WITH HEIGHT UNTIL 20K FT.

.PREV DISCUSSION... /ISSUED 217 PM AST WED DEC 14 2011/

SYNOPSIS...A WEAK FRONTAL BOUNDARY EXPECTED TO MOVE ACROSS THE FA
ON THURSDAY. STRONG HIGH PRESSURE WILL BUILD BEHIND THE FRONTAL
BOUNDARY ON LATE THURSDAY AND FRIDAY.

DISCUSSION...A GENERALLY FAIR PLEASANT AND MAINLY DRY WEATHER
PATTERN WILL CONTINUE ACROSS THE LOCAL ISLANDS DURING THE REST OF
THE AFTERNOON AND THIS EVENING...WITH LITTLE OR NO SIGNIFICANT
RAINFALL ACTIVITY EXPECTED. LATEST SATELLITE AND RADAR IMAGES EARLY
THIS AFTERNOON DEPICTED A WEAK FRONTAL BOUNDARY JUST ACROSS THE
NORTHERN COASTAL WATERS. THIS BOUNDARY IS EXPECTED TO MOVE ACROSS
THE REST OF THE FA TONIGHT AND TOMORROW. MOISTURE WILL INCREASE
WEDNESDAY AND THEN LINGERING THROUGH THURSDAY...AS COLD FRONTAL
BOUNDARY MOVES SOUTHEAST TOWARD AND THEN ACROSS THE LOCAL AREA.
HOWEVER...ONLY ISOLATED TO SCATTERED PASSING SHOWERS ARE EXPECTED IN
ASSOCIATION WITH THIS FEATURE. THE BOUNDARY IS EXPECTED TO MOVE
RAPIDLY ACROSS THE LOCAL ISLANDS. AFTER THE PASSAGE OF THE BOUNDARY
AN INCREASE IN WINDS IS EXPECTED ACROSS THE REGION FOLLOWED BY
