AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
320 PM AST FRI JUN 14 2013

.SYNOPSIS...BREEZY TRADE WINDS WILL CONTINUE TODAY...IN ASSOCIATION
WITH A TROPICAL WAVE AND A STRONG HIGH PRESSURE NORTHEAST OF THE
ISLANDS. THE WEAK TROPICAL WAVE WILL CONTINUE TO MOVE QUICKLY SOUTH
OF THE AREA WITHOUT AFFECTING DIRECTLY THE LOCAL ISLANDS. ANOTHER
PULSE OF MOISTURE WILL BRING SOME SHOWERS AND A FEW THUNDERSTORMS
ACROSS THE ISLANDS ON SATURDAY. WEATHER CONDITIONS WILL IMPROVE ON
SUNDAY WHEN AN AIR OF DRY AND STABLE AIR MASS MOVE OVER THE REGION.

&&

.DISCUSSION...A WEAK TROPICAL WAVE WILL CONTINUE TO MOVE AWAY FROM
THE REGION THE REST OF TODAY. SATELLITE BLENDED PWAT ANALYSIS AS
WELL AS THE GPS MET DATA HAVE SHOWED A RAPID DRY AIR ENTRAINMENT
FROM THE EAST. PRECIPITABLE WATER VALUES HAS DECREASED RAPIDLY SINCE
THIS MORNING FROM 2.14 INCHES TO 1.6 INCHES AT CHRISTIANSTED...ST
CROIX. THIS DRY AND STABLE AIR MASS WILL CONTINUE TO SPREAD OVER
MAINLAND PUERTO RICO DURING THE REST OF THE AFTERNOON HOURS AND
PERSIST UNTIL AROUND 15/06Z WHEN ANOTHER PULSE OF MOIST AIR IS
FORECAST TO MOVE OVER THE ISLANDS FROM THE SOUTHEAST. THE SUBEQUATORIAL
RIDGE LOCATED OVER THE LEEWARD ISLANDS IN COMBINATION WITH DRY AIR
ADVECTION FROM THE EAST HAVE INHIBITED THE DEVELOPMENT OF SHOWERS
AND THUNDERSTORMS ACROSS THE AREA TODAY. ANOTHER FACTOR THAT HELP
TO INHIBIT SHOWER DEVELOPMENT IS THE FAIRLY STRONG LLVL FLOW THAT
DELAY THE SEA BREEZE FORMATION OVER WESTERN PUERTO RICO. FOR THE
REST OF TODAY...EXPECT LITTLE SHOWER ACTIVITY...IF ANY...DEVELOPING
OVER NORTHWESTERN PUERTO RICO LATE THIS AFTERNOON. THEN...A PULSE
OF MOIST AIR WILL BRING SOME CLOUDS AND A FEW SHOWERS ACROSS EASTERN
PUERTO RICO SATURDAY MORNING...FOLLOWING BY SOME AFTERNOON CONVECTION
OVER WESTERN PUERTO RICO SATURDAY AFTERNOON. THE DRY AND STABLE CONDITIONS
WILL RETURN ON SUNDAY AS A BIG AREA OF DRY AIR WITH SAHARAN DUST WILL
ENCOMPASS THE FORECAST AREA. THIS STABLE WEATHER PATTERN WILL PERSIST
UNTIL AT LEAST TUESDAY.

459 AM AST SAT JUN 15 2013

.SYNOPSIS...AT UPPER LEVELS...A RIDGE OVER THE CARIBBEAN JUST
SOUTH OF PUERTO RICO WILL BUILD WESTWARD AS A TROUGH BRUSHING CUBA
MOVES TO THE NORTH OF THE LOCAL AREA NOW THROUGH MONDAY. A CUT OFF LOW
FORMS IN THE TROUGH SUNDAY NIGHT AND CONTINUES NORTHEAST OF THE
LEEWARD ISLANDS THROUGH MUCH OF NEXT WEEK. THIS ALLOWS A WEAK
TROUGH TO REMAIN JUST WEST OF THE FORECAST AREA FOR MUCH OF THE
WEEK.

AT MID LEVELS...A RIDGE EXTENDS NORTHEAST TO HIGH PRESSURE IN THE
CENTRAL ATLANTIC. WEAK TROUGHING FORMS OVER THE LOCAL AREA
BEGINNING ON SUNDAY DUE TO THE UPPER LEVEL TROUGH UNTIL HIGH
PRESSURE BUILDS BACK IN FROM THE EAST LATE NEXT WEEK. EXCEPT FOR
SOME MOISTURE TODAY...MOISTURE IS GENERALLY LIMITED EXCEPT FOR
WEDNESDAY AND THURSDAY.

AT LOWER LEVELS...A WEAK TROUGH WILL MOVE THROUGH THE LOCAL AREA
THIS MORNING FOLLOWED BY A NARROW SLOT OF SOMEWHAT DRIER AIR. LOW
LEVEL MOISTURE PERSISTS HOWEVER UNTIL LATE MONDAY AND RETURNS
AGAIN ON TUESDAY. A TROPICAL WAVE MOVES THROUGH THE AREA ON
WEDNESDAY AND THURSDAY OF NEXT WEEK FOLLOWED BY MUCH DRIER AIR
THROUGH SATURDAY.

.DISCUSSION...MOISTURE INCREASED OVERNIGHT AS PRECIPITABLE WATER...
AS MEASURED BY THE SOUNDER IN BAYAMON...SURPASSED TWO INCHES. HEAVY
SHOWERS MOVED WEST NORTHWEST AT 18 TO 28 KNOTS THROUGH PUERTO

BEYOND 10 NAUTICAL MILES IN A STREAM THAT WAS STILL ACTIVE AS OF
4:45 AM AST. MOISTURE CONTINUES THROUGH THE DAY...AND THE BEST
MOISTURE EXITS INTO THE MONA PASSAGE BY 16/00Z TAKING MOST OF THE

DURING THE NEXT 7 TO 10 DAYS HIGH PRESSURE AT THE SURFACE IN THE
MID ATLANTIC RETREATS TO THE NORTHEAST SOMEWHAT...BUT STRENGTHENS.
HENCE MODERATE TO FRESH TRADE WINDS CONTINUE THROUGHOUT THE PERIOD
WITH LITTLE CHANGE IN STRENGTH. MOISTURE DURING THIS PERIOD
CONTINUES RICH UP TO ABOUT 6 KFT...BUT EXCEPT FOR A SHORT BREAK
WEDNESDAY AND THURSDAY THE ATMOSPHERE AT MID LEVELS IS DRY. DEEP HIGH
CLOUDS ARE GENERALLY PRESENT EXCEPT MONDAY AND TUESDAY JUST BEFORE A
TROPICAL WAVE COMES THROUGH ON WEDNESDAY. THE WAVE SHOULD BRING
SIGNIFICANT RAIN AMOUNTS TO THE AREA AND IS FOLLOWED IMMEDIATELY
BY 25 TO 35 KNOT WINDS AT 850 MB AND MORE SAHARAN DUST. SHOWERS
ARE EXPECTED TO CONTINUE INTO THURSDAY WITH THIS WAVE...HOWEVER
MID LEVELS DRY CONSIDERABLY THURSDAY NIGHT AND REMAIN VERY DRY

OF NEXT WEEK.

500 AM AST SUN JUN 16 2013

.SYNOPSIS...AT UPPER LEVELS...HIGH PRESSURE WILL SHIFT WEST TO THE
CARIBBEAN SOUTH OF CUBA AS LOW PRESSURE DIGS SOUTH AND CUTS OFF
JUST NORTH OF SAINT THOMAS DURING THE EARLY PART OF THE WEEK.
WEAK LOW PRESSURE CONTINUES OVER THE GREATER ANTILLES KEEPING FLOW
SOUTHWESTERLY DURING THE WEEK. HIGH PRESSURE RIDGES IN FROM THE
TROPICAL ATLANTIC LATE IN THE WEEK.

AT MID LEVELS...LOW PRESSURE AND WEAK GRADIENTS PERSIST OVER AND
TO THE NORTH OF THE AREA THROUGH MUCH OF THE WEEK. HIGH PRESSURE
WILL RIDGE IN FROM THE EAST LATE IN THE WEEK. THE BEST MOISTURE OF
WEEK WILL BE ON WEDNESDAY AND THURSDAY WHEN A TROPICAL WAVE COMES THROUGH.

AT LOWER LEVELS...HIGH PRESSURE CONTINUES OVER THE CENTRAL
ATLANTIC THROUGHOUT THE WEEK WITH LOW PRESSURE IN THE SOUTHWEST
CARIBBEAN. THIS WILL CONTINUE MODERATE TO FRESH TRADE WINDS FROM
THE EAST SOUTHEAST. LOW LEVEL MOISTURE PERSISTS THROUGH MONDAY
BUT REMAINS VERY SHALLOW. WINDS AT 850 MB INCREASE AND TURN
SOUTHEAST AS A TROPICAL WAVE COMES THROUGH LATE ON WEDNESDAY.
MOISTURE DECREASES FAIRLY RAPIDLY AFTER THAT BUT RETURNS BRIEFLY
ON THE FOLLOWING SUNDAY.

&&

.DISCUSSION...ONLY SPRINKLES WERE OBSERVED OVERNIGHT AS ATMOSPHERE
HAS TURNED MORE STABLE AND AIR ABOVE 6 KFT HAS BECOME
SIGNIFICANTLY DRIER. PRECIPITABLE WATER AT SAINT CROIX DROPPED
BELOW 1.5 INCHES. EVEN THE HIGHER CLOUDS ARE NOW LOCATED
PREDOMINANTLY OVER HISPANIOLA. THIS WILL ALLOW GOOD PENETRATION
OF THE SUNLIGHT AND FORCE A SEA BREEZE OVER THE LOCAL COASTLINES
THAT WILL ALSO ACCELERATE THE TRADE WINDS NEAR SHORE. THEREFORE
EXPECT MORE WIND TODAY THAN YESTERDAY. EXPECTED MORE SHOWER
ACTIVITY YESTERDAY...BUT DRIER MID LEVELS AND CONSIDERABLE
SAHARAN DUST GENERATED AFTERNOON SHOWERS ONLY IN A SMALL PORTION
OF THE NORTHWEST. LITTLE HAS CHANGED TO BRING MORE ACTIVITY TODAY
AND HAVE LEFT POPS QUITE LOW OVER THE AREA. IT APPEARS THAT THIS
WILL CONTINUE UNTIL AROUND WEDNESDAY MORNING...WHEN A TROPICAL
WAVE PUSHES THROUGH AND SHOWERS AND THUNDERSTORMS RETURN TO THE
AREA. ALSO THE GFS IS SHOWING WINDS AT 850 MB EXCEEDING 35 KNOTS
OVER SAN JUAN AND MUCH OF THE FORECAST AREA AFTER WEDNESDAY NOON.
WITH SOMEWHAT DRY MID LAYERS THIS MAY CAUSE STRONG WINDS TO REACH
THE SURFACE DURING SHOWERS AND THUNDERSTORMS WEDNESDAY NIGHT AND

FORM AND MOVE THROUGH WITH ANY ORGANIZATION. DRIER WEATHER WILL
RETURN ON FRIDAY AND SATURDAY.
