AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
303 PM AST MON JUN 10 2013

.SYNOPSIS...SURFACE HIGH PRESSURE OVER THE CENTRAL ATLANTIC IS
EXPECTED TO REMAIN THERE FOR THE NEXT FEW DAYS...CAUSING MODERATE
TO FRESH TRADE WINDS WINDS ACROSS THE LOCAL AREA. UPPER TROUGH
NORTH OF HISPANIOLA WILL SLOWLY MOVE TO THE NORTHEAST AND NORTH OF
OUR LOCAL AREA AS IT WEAKENS BY WEDNESDAY. SOME SAHARAN DUST
EXPECTED LATE WEDNESDAY AND A TROPICAL WAVE WILL MOVE OVER THE
AREA ON FRIDAY.

&&

.DISCUSSION...SCATTERED TO LOCALLY NUMEROUS SHOWERS WITH ISOLATED
THUNDERSTORMS DEVELOPED ACROSS THE LOCAL AREA. THE THUNDERSTORMS
WERE MOSTLY LIMITED TO THE SOUTHWESTERN QUADRANT OF PUERTO RICO AS THE
AVAILABLE MOISTURE COMBINED WITH DIURNAL HEATING AND SEA BREEZE
CONVERGENCE. HOWEVER...A FEW OF THE PASSING SHOWERS DID HAVE
THUNDER AND LIGHTNING FOR A FEW MINUTES.

AVAILABLE MOISTURE IS EXPECTED TO INCREASE ACROSS THE CARIBBEAN
WATERS DURING THE OVERNIGHT HOURS AS IT SLOWLY MOVES NORTH ON
TUESDAY. THIS WILL CAUSE SHOWERS ONCE AGAIN ACROSS PUERTO
RICO...WITH THUNDERSTORMS EXPECTED IN THE WESTERN SECTIONS OF
PUERTO RICO ONCE AGAIN. SOME SAHARAN DUST WILL BE MAKING ITS WAY
IN ON WEDNESDAY INTO THURSDAY...CAUSING SOME HAZY SKIES JUST
BEFORE A TROPICAL WAVE COMES IN ON FRIDAY...INCREASING AVAILABLE
MOISTURE SIGNIFICANTLY AS WELL AS 850MB THETA-E. SHOWER AND
THUNDERSTORM ACTIVITY IS QUITE POSSIBLE AS THIS WAVE PASSES.


&&

.AVIATION...VFR CONDITIONS EXPECTED TO PREVAIL AT ALL TAF SITES
WITH A FEW SHOWERS AND ISOLATED THUNDERSTORMS IN THE VICINITY OF
TJMZ THROUGH ABOUT 10/21Z. FAST MOVING SHOWERS ARE POSSIBLE FROM
TIME TO TIME AT TNCM/TIST/TISX AND TJSJ. LOW LEVEL WINDS FROM THE
EAST AT 10 TO 20 KNOTS.

&&

.MARINE...MAIN HAZARD WILL BE SHOWERS AND THUNDERSTORMS OVER THE
WATERS...SEAS WILL BE UP TO 6 FEET AND WINDS UP TO 20 KNOTS. SMALL
CRAFT SHOULD EXERCISE CAUTION.

914 PM AST MON JUN 10 2013

.UPDATE...THE 11/00Z SOUNDING CAME IN WITH SIMILAR MOISTURE TO THE
10/12Z SOUNDING AND WAS WETTER THAN 24 HOURS AGO WITH 1.93 INCHES
OF PRECIPITABLE WATER. HIGH CLOUDS HAVE DOMINATED THE SKIES OVER
THE LOCAL AREA AS A SOUTHWEST JET CONTINUES OVER THE AREA WITH 50
KNOT PLUS WINDS AT 46 KFT. CONVECTIVE ACTIVITY HAS COMPLETELY DIED
OUT OVER LAND AND A FEW NARROW BANDS OF SHOWERS ARE MOVING WEST
ACROSS THE CARIBBEAN. IT IS UNLIKELY THAT THESE WILL MAKE IT
ACROSS THE SOUTHERN PART OF PUERTO RICO WITH MUCH STRENGTH
ESPECIALLY SINCE BUOY 42085 AND OTHER LAND STATIONS SHOW SOME
OFFSHORE COMPONENT. LATEST GFS FORECAST OF PRECIPITABLE WATER
SUGGESTS AN INCREASE TO OVER 2 INCHES AGAIN TOMORROW AFTERNOON AND
EVENING...ALTHOUGH MOISTURE WAS SUPPOSED TO DECREASE OVERNIGHT
THEREFORE HAVE BUMPED POPS UP SOMEWHAT OVER PUERTO RICO...AS LAST
SEVERAL DAYS HAVE SEEN HEAVY SHOWERS...THOUGH LITTLE FLOODING AND
LITTLE HAS CHANGED. OTHERWISE DISCUSSION BELOW HOLDS UP WELL.
LOOKING AHEAD TO THE WEEKEND...THE NAAPS FORECAST IS SHOWING ONE
OF THE MORE SIGNIFICANT DUST EVENTS OF THIS YEAR SHAPING UP FOR
SATURDAY AND SUNDAY. THIS MODEL SOMETIMES OVER-FORECASTS BUT DO
EXPECT MORE THAN TODAY OR YESTERDAY THEN.

[cycloneye]

Good morning. A few showers will move thru PR and adjacent islands today. A Tropical Wave will move thru the area on Friday increasing the showers.

551 AM AST TUE JUN 11 2013

.SYNOPSIS...SURFACE HIGH PRESSURE WILL CONTINUE ACROSS THE CENTRAL ATLANTIC
FOR AT LEAST THE NEXT FEW DAYS AND WILL MAINTAIN MODERATE TO FRESH
TRADE WINDS THROUGH THURSDAY. A WEAK TROUGH MOVING THROUGH THE
LOCAL WATERS IS BRINGING AN INCREASE OF SHOWER ACTIVITY. SAHARAN
DUST HAZE WILL BEGIN TO REACH THE AREA LATE WEDNESDAY AND A
TROPICAL WAVE WILL MOVE ACROSS THE AREA ON FRIDAY.

&&

.DISCUSSION...SHOWERS CONTINUED TO MOVE ACROSS THE LOCAL WATERS
WITH A FEW AFFECTING THE EASTERN COASTAL PORTIONS OF PUERTO RICO.
THESE SHOWERS WILL CONTINUE TO AFFECT THE EASTERN PORTIONS OF
PUERTO RICO AND THE EASTERN ADJACENT ISLANDS.

THIS AFTERNOON...LINGERING MOISTURE IN COMBINATION WITH LOCAL
EFFECTS WILL PRODUCE AFTERNOON CONVECTION MAINLY ACROSS THE
WESTERN INTERIOR SECTIONS. MOISTURE IS EXPECTED TO BEGIN TO
DECREASE LATER TODAY...THEREFORE EXPECT LESS SHOWER COVERAGE FOR
WEDNESDAY AND THURSDAY. STILL EXPECTING THE EFFECT OF A TROPICAL
WAVE NOW LOCATED AT AROUND 45 W. MODELS ARE SLIGHTLY SLOWER.
TIMING WILL BE THE KEY FACTOR FOR SHOWERS AND THUNDERSTORMS
DEVELOPMENT ON FRIDAY AFTERNOON AND EVENING.

&&

.AVIATION...VFR CONDITIONS EXPECTED AT ALL TAF SITES THROUGH THE
FORECAST PERIOD...WITH VICINITY SHOWERS AND AN ISOLATED THUNDERSTORM
OR TWO NEAR TJMZ AND TJBQ BETWEEN 11/18Z AND 11/22Z. LOW LEVEL WINDS
FROM THE EAST AT 10 TO 20 KNOTS..

NATIONAL WEATHER SERVICE SAN JUAN PR
305 PM AST TUE JUN 11 2013

.SYNOPSIS...RIDGE ALOFT WILL CONTINUE TO EXTEND ACROSS THE EASTERN
AND CENTRAL CARIBBEAN AS TUTT TO THE WEST OF LOCAL ISLANDS WEAKENS.
A SECOND TUTT WILL DEVELOP ACROSS THE CENTRAL ATLANTIC INTO THE
NORTHEASTERN CARIBBEAN EARLY NEXT WORK WEEK. SURFACE HIGH ACROSS
THE CENTRAL ATLANTIC WILL CONTINUE TO PROMOTE FRESH TO MODERATE
TRADES FOR THE NEXT FEW DAYS. NEXT TROPICAL WAVE IS EXPECTED TO
MOVE OVER THE LOCAL ISLANDS ON FRIDAY.

&&

.DISCUSSION...CLOUDY SKIES WERE OBSERVED ACROSS PUERTO RICO AND
USVI THROUGHOUT THE DAY...WITH ISOLATED PASSING SHOWERS ACROSS
SECTIONS OF EASTERN PUERTO RICO/USVI FROM TIME TO TIME. SHOWERS
WITH THUNDERSTORMS WERE ALSO NOTED IN THE AFTERNOON ACROSS THE
CORDILLERA CENTRAL AND THE NORTHERN SLOPES OF PR.

A RIDGE ALOFT WILL CONTINUE TO EXTEND ACROSS THE EASTERN AND
CENTRAL CARIBBEAN...AS TUTT TO THE WEST OF LOCAL ISLANDS WEAKENS.
AS THIS PATTERN EVOLVES...LOW LEVEL MOISTURE WILL CONTINUE TO
INCREASE OVER THE AREA. THIS WILL RESULT IN PASSING SHOWERS
DURING THE MORNING HOURS ACROSS THE EASTERN HALF OF PUERTO
RICO...USVI AND REGIONAL WATERS FOLLOWED BY AFTERNOON CONVECTION
ACROSS THE CORDILLERA CENTRAL AND WESTERN PUERTO RICO. THIS
WEATHER PATTERN WILL CHANGE ON THURSDAY AS A DRIER AIR MASS
MOVES IN...AHEAD OF NEXT TROPICAL WAVE THAT WILL REACH THE AREA
ON FRIDAY. AS TROPICAL WAVE APPROACHES...SHOWER COVERAGE AND
THUNDERSTORM INTENSITY WILL INCREASE ACROSS THE LOCAL ISLANDS
AS SOON AS EARLY FRIDAY MORNING. WEATHER CONDITIONS ARE EXPECTED
TO IMPROVE LATE SATURDAY NIGHT THROUGH EARLY NEXT WORK WEEK AS
A DRIER AND STABLE AIR MASS PREVAILS OVER THE AREA. THEREAFTER...
MOISTURE IS EXPECTED TO POOL ONCE AGAIN ACROSS THE EASTERN
CARIBBEAN BY MIDWEEK NEXT WEEK AS TUTT DEVELOPS ACROSS THE CENTRAL
ATLANTIC INTO THE EASTERN CARIBBEAN.

&&

.AVIATION...AFTERNOON CONVECTION WILL CONTINUE TO AFFECT TJMZ
THRU AT LEAST 21Z...RESULTING IN MVFR OR EVEN IFR CONDS. OTHER
TAF SITES SUCH AS TJSJ...TJPS AND TJBQ WILL EXPERIENCE VCSH/VCTS
THRU 21Z. ELSEWHERE...VFR CONDS WILL PREVAIL WITH BKN CLOUDS AT
FL250. LOW LEVEL WINDS FROM THE E TO ESE AT 10-20 KT.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
956 PM AST TUE JUN 11 2013

.UPDATE...DENSE CIRRUS CONTINUE TO STREAM FROM THE SOUTHWEST OVER
THE LOCAL AREA KEEPING SKIES CLOUDY. NEVERTHELESS THIS DID NOT
PREVENT CONSIDERABLE CONVECTIVE ACTION IN HIGH PRECIPITABLE WATER
OF NEARLY 2 INCHES AGAIN IN THE 12/00Z SOUNDING. MIMIC PRODUCT
SHOWS GOOD MOISTURE GROWING JUST EAST OF THE LEEWARD ISLANDS AS IT
FLOW INTO THE LOCAL AREA AND EXPECT THIS WILL CONTINUE THROUGH AT
LEAST WEDNESDAY. THE GFS INDICATES THAT THE HIGH CLOUD COVER WILL
ALSO CONTINUE THROUGH AT LEAST 13/00Z. THE NAAPS PRODUCT ALSO
INDICATES THAT SAHARAN DUST WILL ENTER THE AREA WEDNESDAY AND
INCREASE PRETTY MUCH EACH DAY THROUGH SUNDAY. IT ALSO SHOWS THAT
DUST WILL REACH LEVELS NOT REACHED THIS YEAR SO FAR BY SATURDAY OR
SUNDAY.


&&

.DISCUSSION...THE DISCUSSION BELOW IS HOLDING FAIRLY WELL. LATEST
11/18Z MODEL RUN DID NOT SHOW MOISTURE ABATING AFTER THE TROPICAL
WAVE PASSAGE ON FRIDAY...HOWEVER. THIS MEANS THAT SHOWER ACTIVITY
MAY CONTINUE DESPITE HIGHER DUST CONTENT OF LOWER LAYERS. MID
LEVELS ARE SOMEWHAT DRY IN ANY EVENT THROUGH THE NEXT 7 DAYS EVEN
AS THE WAVE PASSES...THEREFORE THE EFFECTS OF THE WAVE MAY BE
MUTED. MOISTURE IN THE COLUMN...THAT IS PRECIPITABLE WATER...SEEMS
TO HOLD FAIRLY WELL AND IS LIKELY TO SUSTAIN SOME CONVECTION IN
THE WEST IN THE AFTERNOONS EVERY DAY THROUGH AT LEAST SUNDAY.
UNFORTUNATELY THE ECMWF REACHES A MINIMUM RELATIVE HUMIDITY AT 850
MB ON MONDAY MORNING JUST AS THE GFS REACHES A MAXIMUM FOR THE
WEEK. THEREFORE ANY CHANGES IN THE LONG RANGE FORECAST SHOULD WAIT
FOR CONFIRMATION FROM THE 00Z RUN. FORECAST DOES SEEM TO ACCOUNT
FOR THIS ALREADY...NEVERTHELESS. MEANWHILE FLOW FROM THE
SOUTHWEST BEARING HIGH MOISTURE WILL CONTINUE TO GENERATE A MORE
OR LESS SOLID OVERCAST AND CLOUDY OR MOSTLY CLOUDY CONDITIONS OVER
THE AREA THROUGH WEDNESDAY WITH A FEW BREAKS ON THURSDAY.

Good morning. Scattered showers will move thru PR today subside on Thursday but increase on Friday as a Tropical Wave moves thru on that day.

ACROSS THE CENTRAL ATLANTIC WILL CONTINUE TO PROMOTE FRESH TO
MODERATE TRADES FOR THE NEXT FEW DAYS. NEXT TROPICAL WAVE IS
EXPECTED TO MOVE OVER THE LOCAL ISLANDS ON FRIDAY.


&&

.DISCUSSION...INCREASING SHOWER COVERAGE HAVE OCCURRED IN THE PAST
FEW HOURS OVER THE EASTERN PORTIONS OF PUERTO RICO. THESE SHOWERS
ARE EXPECTED TO LAST THROUGH AT LEAST MID MORNING MAINLY AFFECTING
THE EASTERN PORTIONS OF PUERTO RICO INCLUDING THE SAN JUAN
METROPOLITAN AREA.

AT THE BEGINNING OF THE WEEK A DRIER AIR MASS WAS FORECAST TO
PREVAILED OVER THE REGION FROM WEDNESDAY AND THURSDAY. THE MODELS
HAVE BACK OFF THE DRY SLOT FOR THESE TWO DAYS. THE NEW MODELS RUNS
ARE STILL SUGGESTING FOR THIS DRIER AIR MASS TO MOVE OVER THE AREA
ON THURSDAY BUT IT WILL NOT BE AS DRY AS EXPECTED...THEREFORE
EXPECT MORNING SHOWERS AFFECTING THE EASTERN PORTIONS OF PUERTO
RICO AND AFTERNOON SHOWERS AND THUNDERSTORMS ALONG THE CORDILLERA
CENTRAL AND WESTERN PORTION OF PUERTO RICO.

A TROPICAL WAVE WILL MOVE ACROSS THE REGION ON FRIDAY...SHOWER COVERAGE
AND THUNDERSTORM INTENSITY WILL INCREASE ACROSS THE LOCAL ISLANDS.
