.SYNOPSIS...A MID TO UPPER LEVEL RIDGE WILL CONTINUE TO EXTEND
ACROSS THE LOCAL AREA FOR THE NEXT FEW DAYS...BEFORE HEIGHTS
BEGIN TO FALL AGAIN BY THE END OF THE WEEK...AS A TROUGH BECOMES
LOCATED JUST WEST THROUGH NORTHWEST OF THE FA DURING THE UPCOMING
WEEKEND.

&&

.DISCUSSION...THE COMBINATION OF THE AFOREMENTIONED MID TO UPPER
LEVEL RIDGE AND A RELATIVELY DRY AND STABLE AIR MASS WILL
CONTINUE TO RESULT IN A GENERALLY FAIR WEATHER PATTERN ACROSS THE
FA FOR THE NEXT SEVERAL DAYS. HOWEVER...THERE WILL STILL BE BANDS
AND PATCHES OF MOISTURE MOVING ACROSS THE LOCAL AREA FROM TIME TO
TIME...RESULTING IN INTERVALS OF CLOUDINESS AND A FEW PASSING
SHOWERS OVER PARTS OF THE LOCAL ISLANDS.

&&

.AVIATION...VFR CONDITIONS ARE EXPECTED ACROSS THE LOCAL TAF
SITES THROUGH THE FORECAST PERIOD. PASSING SHWRS EMBEDDED IN A
EAST TO NORTHEAST TRADE WIND FLOW WILL CONTINUE TO AFFECT THE
FLYING AREA FM TIME TO TIME. VCSH CAN BE EXPECTED ACROSS USVI TAF
SITES AND TJSJ THROUGH 28/14Z. THE AVG 0-6 KM WINDS WILL REMAIN
MAINLY FM THE NE AT 10-20 KTS.

.MARINE...EXPECT WINDS OF 18 KNOTS OR LESS AND SEAS OF 6 FEET OR
LESS ACROSS THE REGIONAL WATERS THROUGH AT LEAST FRIDAY. SMALL

.SYNOPSIS...UPPER LEVEL RIDGE WILL BEGIN TO BREAK DOWN FRI AS
BROAD TROUGH AMPLIFIES ACROSS THE ATLC. THIS WILL INDUCE THE
DEVELOPMENT OF AN INDUCED SFC TROF AND AN EXTRATROPICAL LOW PRES
SYSTEM NE OF PR MON.

&&

.DISCUSSION...EARLY MORNING SHOWERS WILL END SHORTLY AFTER SUNSET
WITH A WARM DRY AFTERNOON EXPECTED UNDER STRONG UPPER LEVEL RIDGE.
VERY LITTLE CONVECTION EXPECTED TONIGHT AS AIR MASS CONTINUES TO
DRY OUT. THERE WILL BE A SLIGHT MOISTURE RECOVERY FRI BUT AREA
STILL UNDER THE INFLUENCE OF UPPER LEVEL RIDGE SO NOT ANTICIPATING
MUCH. THINGS THEN START TO CHANGE FRI NIGHT AS HEIGHTS BEGIN TO FALL
IN RESPONSE TO SHORTWAVE TROUGH FCST TO EXIT THE SOUTHEAST U.S.
THIS WILL PROMOTE MOISTURE TRANSPORT AND STEEPEN LAPSE RATES AND
ALLOW FOR SHOWERS TO BECOME MORE NUMEROUS ESPECIALLY SAT. AS
SHORTWAVE-TROUGH AMPLIFIES AND GETS CLOSER TO THE AREA SUN AN
INVERTED SFC TROF WILL FORM AND HELP TRIGGER MORE WIDESPREAD CONVECTION.

UPPER TROF AND ASSOCIATED SFC LOW WILL START PULLING OUT TO THE
NORTHEAST MON DRAGGING A CDFNT THROUGH THE AREA MON NIGHT. SIG
LOW-MID LEVEL DRYING WILL START TAKING PLACE MON WITH A SHARP
DECREASE IN CONVECTION EXPECTED MON. FAIR WEATHER WILL THEN
ESTABLISH ACROSS THE ENTIRE REGION NEXT WEEK AS AREA BECOMES UNDER

.SYNOPSIS...AT MID AND UPPER LEVELS...A BROAD HIGH PRESSURE OVER
THE EASTERN CARIBBEAN WILL GRADUALLY GIVE WAY TO A LONG WAVE
TROUGH PASSING BY TO THE NORTH ON MONDAY AND TUESDAY...FOLLOWED
BY A SECOND ON FRIDAY.

AT LOWER LEVELS...EAST NORTHEAST TRADE WIND FLOW WILL CONTINUE AS
HIGH PRESSURE LEAVING THE EASTERN UNITED STATES MERGES WITH A
SECOND OUT OF CANADA AND MOVES EAST OVER A QUICKLY DEEPENING LOW.
TROUGHINESS OVER THE LESSER ANTILLES WILL CULMINATE IN THE
FORMATION OF A LOW NORTH OR NORTHEAST OF PUERTO RICO AND THE
U.S.VIRGIN ISLANDS SUNDAY NIGHT AND MONDAY. THIS LOW WILL DRIFT
NORTHEAST WHILE DEEPENING AND ALLOW COOLER AIR TO PENETRATE THE
AREA AND BRING MOISTURE AND SHOWERS TO THE AREA FOR MUCH OF THE
REST OF THE WEEK.

&&

.DISCUSSION...SHOWERS AND POSSIBLY A THUNDERSTORM DEVELOPED OVER
THE WEST END OF THE CORDILLERA CENTRAL THIS AFTERNOON LEAVING AS
MUCH AS THREE INCHES OF RAIN IN ISOLATED AREAS OF SAN GERMAN.
DRIER AIR WAS SEEN ENTERING THE AREA FROM THE NORTHEAST AND MUCH
FEWER SHOWERS CAN BE SEEN NORTH AND NORTHEAST OF BOTH PUERTO RICO
AND THE U.S. VIRGIN ISLANDS. THIS WILL BE FAIRLY SHORT LIVED.
WHILE FRIDAY WILL HAVE FEWER SHOWERS...SHOWERS RETURN FRIDAY
NIGHT...ESPECIALLY TO THE NORTHEAST PORTION OF PUERTO RICO AND THE
NORTHERN U.S. VIRGIN ISLANDS...AND CONTINUE IN OUR NORMAL DIURNAL
PATTERN FROM THE NORTHEAST OVER THE WEEKEND AND INTO MONDAY. WITH
FLOW FROM THE NORTHWEST AROUND THE LOW DEVELOPING SUNDAY NIGHT...EXPECT
THAT THE USUAL OPPOSITE SIDE SHOWERS WILL NOT BE ABLE TO FORM BUT
THAT MOST SHOWERS WILL COME IN ON THE WINDWARD SIDE. WINDS AT THE
SURFACE DO NOT GAIN AN EASTERLY COMPONENT AGAIN...ACCORDING TO THE
GFS...UNTIL THURSDAY...BUT REMAIN RELATIVELY COOL AND MOIST.

431 AM AST FRI NOV 30 2012

.SYNOPSIS...RIDGE PATTERN WILL BEGIN TO BREAK DOWN TONIGHT AS
SHORTWAVE-TROUGH ACROSS THE GULF COAST STATES AMPLIFY AS IT MOVES
ACROSS THE ATLC. LOW PRES IS FCST TO DEVELOP NE OF THE LEEWARD
ISLANDS MON NIGHT WITH FRESH NNE WINDS ESTABLISHING MON.

&&

.DISCUSSION...STRONG SUBSIDENCE INVERSION IN PLACE AS SEEN ON 00Z
JSJ RAOB. THIS TO LIMIT AFTERNOON CONVECTION TO JUST SPRINKLES OR
VERY SHALLOW SHOWERS. S/W TROUGH ACROSS THE GULF COAST STATES WILL
EMERGE INTO THE WRN ATLC SAT AND BEGIN TO ERODE RIDGE PATTERN
ESTABLISHED ACROSS THE CARIB. AS S/W TROUGH AMPLIFIES ACROSS THE
SW ATLC THIS WILL PROMOTE MOISTURE TRANSPORT...WEAKEN THE CAP AND
STEEPEN LAPSE RATES ACROSS THE AREA. EXPECT CONVECTION TO
GRADUALLY INCREASE SAT AND SUN WITH THE HEAVIEST ACCUMULATIONS EXPECTED
ON SUN DUE TO WEAK STEERING FLOW AND BETTER/STRONGER LOW LEVEL
CONVERGENCE ASSOCIATED WITH STRENGTHENING INVERTED SFC TROF.

BAROCLINIC LOW WILL START DEVELOPING NORTHEAST OF THE LEEWARD
ISLANDS MON NIGHT WITH FRESH NNE WINDS ESTABLISHING ACROSS THE
AREA. LATEST GUIDANCE NOT SHOWING AS MUCH DRYING AS THEY WERE
YESTERDAY WITH PW VALUES REMAINING NEAR NORMAL AND K INDICES AND
H85 THETAE VALUES STAYING HIGH IN THE 30S AND MID 330`S KELVIN
RESPECTIVELY. SO EXPECT THERE WILL BE LOTS OF NOCTURNAL SHALLOW
CONVECTION ALONG THE NORTH COAST MUCH OF NEXT WEEK UNDER BROAD
TROUGH PATTERN. EXPECT ALSO COOLER TEMPERATURES UNDER TROUGHFINESS
AND NORTHERLIES.

&&

.AVIATION...VFR CONDS EXPECTED TO CONTINUE AT ALL TAF SITES DURING THE
NEXT 24 HOURS. HOWEVER...ENE LOW LVL WIND FLOW WILL BRING INTERVALS OF

.DISCUSSION...
AN AREA OF LOW LEVEL MOISTURE TO THE NORTHEAST OF PUERTO RICO WILL

432 AM AST SAT DEC 1 2012

.SYNOPSIS...BROAD MID-UPPER TROUGH WILL DOMINATE THE WRN ATLC INTO
THE CARIBBEAN THROUGH ALL OF NEXT WEEK. INVERTED SFC TROF WILL
BECOME BETTER ORGANIZED TODAY THROUGH SUN AND PUSH SE OF THE AREA
BY MON.

&&

.DISCUSSION...LATEST GUIDANCE SHOWS A QUICK SURGE IN MOISTURE
LATER TODAY WITH PWAT VALUES CLIMBING TO ALMOST TWO INCHES WHICH
IS CLOSE TO TWO STANDARD DEVIATIONS ABOVE NORMAL FOR DEC. S/W
TROUGH NOW EXITING THE FLORIDA PENINSULA WILL AMPLIFY OVER THE
NEXT 48 HRS AS IT MOVES EWD. THIS FEATURE WILL INDUCE AN INVERTED
SFC TROF ACROSS THE AREA AND AID IN THE DEVELOPMENT OF SHOWERS AND
THUNDERSTORMS THIS AFTERNOON THROUGH SUNDAY. BIGGEST CONCERN FOR
HEAVY RAINFALL IS THAT STEERING WINDS ARE FCST TO COLLAPSE LATE
TONIGHT THRU SUN WHICH COULD RESULT IN VERY SLOW MOVING CONVECTION
CAPABLE OF PRODUCING INTENSE RAINFALL RATES. FLASH FLOOD WATCH WAS
ISSUED ON THIS BASIS AND AREAL CVRG WAS DETERMINED BY A DECEMBER
RAINFALL CLIMATOLOGY FROM 1981-2010 WHICH SHOWS THAT MOST HEAVY
RAINFALL EVENTS ACROSS THE ISLAND IN DECEMBER TAKE PLACE ACROSS
NORTHEAST PUERTO RICO. RIVERS IN THIS AREA ARE VERY SHORT IN
LENGTH AND VERY FAST RESPONDERS SO EXPECT TO SEE SOME FLOODING
EITHER TODAY OR TOMORROW.

THINGS IMPROVE SOMEWHAT SUN NIGHT AND MON AS INVERTED TROF PUSHES
SOUTHEAST AND MID LEVELS START TO DRY OUT. HOWEVER...INCREASING
NORTHERLIES AND COOL ADVECTIVE PATTERN WILL RESULT IN NOCTURNAL
SHOWERS ALONG THE NORTH COAST. THIS PATTERN IS LIKELY TO LAST MUCH
OF NEXT WEEK UNDER THE INFLUENCE OF A BROAD TROUGH.

&&

.AVIATION...PASSING SHOWERS WILL CONTINUE TO PREVAIL ACROSS THE
FLYING AREA THROUGH THE FORECAST PERIOD. SHOWER AND THUNDERSTORM
DEVELOPMENT ALSO EXPECTED OVER THE CORDILLERA CENTRAL BETWEEN 01/17Z

AT 05-10 KT WITH SEA BREEZE VARIATIONS.

.DISCUSSION...SCATTERED TO NUMEROUS SHOWERS WITH ISOLATED
THUNDERSTORMS DEVELOPED THIS AFTERNOON MAINLY ACROSS THE EASTERN
