AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JUAN PR
254 PM AST MON APR 27 2015

.SYNOPSIS...HOT AND DRY CONDITIONS EXPECTED DURING THE DAYTIME
FOR MUCH OF PUERTO RICO WHILE THE USVI REMAINS NOT QUITE AS HOT.
HIGH PRESSURES AT THE LOW...MID...AND UPPER LEVELS DOMINATING THE
LOCAL REGION. SOUTH TO SOUTHEAST WIND FLOW DUE TO THE HIGH
PRESSURE ACROSS THE EASTERN ATLANTIC AND THE SURFACE LOW TO THE
NORTH OF THE LOCAL AREA. THE HIGH PRESSURES IN THE MID AND UPPER
LEVELS WILL KEEP A STABLE ATMOSPHERE CAUSING SUBSIDENCE AND DRY
CONDITIONS. SAHARAN DUST EXPECTED TO MOVE IN BY MIDWEEK.

&&

.DISCUSSION...IT HAS BEEN A HOT DAY TODAY ACROSS MOST OF PUERTO
RICO...IN PARTICULAR FOR THE SAN JUAN METRO AREA WHERE THE
TEMPERATURE REACHED 94 DEGREES...BREAKING THE OLD RECORD OF 93 SET
IN 2010. THE 12Z SOUNDING INDICATED A PRECIPITABLE WATER OF ONLY
1.22 INCHES WITH A STRONG TEMPERATURE INVERSION. LITTLE TO NO RAIN
IS EXPECTED LATER IN THE AFTERNOON AND NO RAIN WAS OBSERVED DURING
THE MORNING AND EARLY AFTERNOON HOURS.

INTERESTING WIND FLOW PATTERN WAS OBSERVED TODAY WHEN THE WIND
FROM THE SOUTH SOUTHEAST ENCOUNTERED MAINLAND PUERTO RICO THEN
BECAUSE OF THE LOCAL TERRAIN...A SHADOW OF WIND IS OBSERVED ACROSS
NORTH CENTRAL AND NORTHWESTERN PR...WHILE THE GENERAL WIND FLOW
THEN CAUSES AN EDDY AND LOOPS BACK TO THE WEST AND INTO ARECIBO
TO AGUADILLA...GIVING THEM A NORTHERLY WIND AND ABOUT 10 DEGREES
COOLER TEMPS THAN THE SAN JUAN METRO. THE SEA BREEZE DID NOT
DEVELOP OVER THE SAN JUAN AREA.

THIS SOUTH SOUTHEAST WIND FLOW IS EXPECTED TO CONTINUE THROUGH
THIS WEEK. THERE IS NO SIGNIFICANT CHANGE IN THE WEATHER PATTERN
ACCORDING TO GUIDANCE. SO WE DO EXPECT NEAR RECORD TEMPS AT LEAST
THROUGH THURSDAY WHILE THE TEMPS OVERNIGHT WILL ALSO BE ON THE
WARM SIDE...CLOSE TO 80 DEGREES IN THE LOWER ELEVATIONS.
ALSO...LITTLE TO NO RAIN IS EXPECTED AS CONTINUED DRY AIR IS
MOVING IN. IN FACT...NAAPS MODEL SUGGESTS THAT SOME SAHARAN DUST
IS MOVING IN FOR WEDNESDAY THROUGH FRIDAY...WHICH WILL HELP KEEP
THE CHANCES OF SIGNIFICANT RAINFALL VERY LOW.

A FAIR AND STABLE WEATHER PATTERN WILL CONTINUE TO PREVAIL ACROSS
THE LOCAL ISLANDS OVER THE NEXT SEVERAL DAYS...UNDER A MID TO
UPPER LEVEL RIDGE AND LIMITED LOW LEVEL MOISTURE. SHOWER ACTIVITY...
IF ANY...WILL BE SHALLOW AND FOCUSED EACH AFTERNOON ACROSS THE
NORTHERN SLOPES OF PUERTO RICO. ABOVE NORMAL TEMPERATURES WILL
PREVAIL ACROSS THE AREA...BUT ESPECIALLY ALONG THE NORTHERN SLOPES
AS A SOUTHERLY WIND FLOW PREVAILS.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL AT ALL TAF SITES FOR THE
NEXT 24 HOURS. LITTLE TO NO SIGNIFICANT WEATHER IS EXPECTED.
LIGHT AND VARIABLE SURFACE WINDS EXPECTED OVERNIGHT.FEW VCNTY
PASSING SHOWERS POSSIBLE IN AND AROUND TJBQ AND TJSJ AFTER 27/17Z.

.MARINE...TRANQUIL MARINE CONDITIONS WILL CONTINUE WITH SEAS UP
TO 4 FEET AND WINDS AROUND 15 KNOTS.

&&

.PREV DISCUSSION... /ISSUED 316 PM AST SUN APR 26 2015/

SYNOPSIS...STRONG MID TO UPPER LEVEL RIDGE WILL MAINTAIN IT HOLD
OVER THE FORECAST AREA AND REMAIN THE DOMINANT WEATHER FEATURE AT
LEAST UNTIL THE LATTER PART OF THE UPCOMING WORK WEEK. AT THE SURFACE...
RECEDING HIGH PRESSURE ACROSS THE SUBTROPICAL ATLANTIC WILL
MAINTAIN A LIGHT SOUTHERLY WIND FLOW THROUGH THE EARLY PART OF THE
NEXT WEEK. THIS WILL RESULT IN WARMER THAN NORMAL TEMPERATURES
ACROSS THE REGION DURING THE NEXT FEW DAYS.

DISCUSSION...LOCAL SEA BREEZE CONVERGENCE IN SOME AREAS ALONG
WITH PERSISTENT SOUTHERLY FLOW ALLOWED FOR A SLIGHT INCREASE IN
CLOUDINESS ACROSS PARTS OF THE ISLANDS TODAY. HOWEVER...NO
SIGNIFICANT RAINFALL WAS OBSERVED OR DETECTED SO FAR BY THE
DOPPLER WEATHER RADAR. THE DOMINANT WARM SOUTHERLY WINDS...AND
STRONG SUBSIDENCE ALOFT QUICKLY SUPPRESSED AND LIMITED ANY
CONVECTIVE DEVELOPMENT. THIS SOUTHERLY FLOW HOWEVER ALLOWED
DAYTIME TEMPERATURES TO INCREASE AN ADDITIONAL DEGREE OR TWO IN
THE AFTERNOON...WITH A NEW RECORD HIGH TEMPERATURE BEING SET AT
THE SAN JUAN INTERNATIONAL AIRPORT. THIS OVERALL HOT AND DRY
WEATHER PATTERN IS EXPECTED TO CONTINUE DURING THE NEXT FEW DAYS.

DURING THE OVERNIGHT HOURS...MOSTLY CLEAR AND TRANQUIL WEATHER
CONDITIONS WITH VERY LITTLE OR NO SHOWER ACTIVITY EXPECTED ACROSS
THE REGION. A BRIEF AND LIGHT SHOWER MAY MOVE INLAND ALONG PORTIONS
OF THE SOUTH AND EAST COASTAL SECTIONS BUT ALL IN ALL SHOWER
ACTIVITY WILL BE LIMITED OVER LAND.

ON MONDAY...MOSTLY SUNNY SKIES EXPECTED ONCE AGAIN WITH WARM DAYTIME
TEMPERATURES AND LIMITED OR NO SHOWER ACTIVITY DURING THE DAY. BASED
ON LATED MODEL GUIDANCE ALL SUGGEST NO SIGNIFICANT RAINFALL OR WEATHER
FEATURE EXPECTED TO AFFECT THE REGION FOR THE NEXT SEVERAL DAYS. MOSTLY
FAIR AND STABLE CONDITIONS SHOULD PERSIST FOR MOST OF THE WORK WEEK.

AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS THE LOCAL FLYING
AREA FOR THE NEXT 24 HOUR WITH LITTLE TO NO SIGNIFICANT WX EXPECTED.
SFC WINDS WILL BE FROM THE SOUTH SOUTHEAST AT AROUND 10 KNOTS WITH
SEA BREEZE VARIATIONS UNTIL AROUND 26/22Z...BECOMING LIGHT AND
VARIABLE FOR MOST OF THE TERMINALS THEREAFTER. SOUTHEAST WINDS AT
AROUND 10-15KT EXPECTED ACROSS THE LOCAL AREA AFTER 27/12Z.

MARINE...A GENTLE TO MODERATE SOUTHERLY WIND FLOW OF 15 KNOTS OR
LESS AND SEAS OF 4 FEET OR LESS WILL PERSIST OVERNIGHT AND MONDAY.
PLEASE REFER TO THE LATEST COASTAL WATERS FORECAST ISSUED BY THE
NATIONAL WEATHER SERVICE WFO SAN JUAN FOR ADDITIONAL INFORMATION.

ACROSS THE REGION DURING THE NEXT FEW DAYS.

DISCUSSION...LOCAL SEA BREEZE CONVERGENCE IN SOME AREAS ALONG
WITH PERSISTENT SOUTHERLY FLOW ALLOWED FOR A SLIGHT INCREASE IN
CLOUDINESS ACROSS PARTS OF THE ISLANDS TODAY. HOWEVER...NO
SIGNIFICANT RAINFALL WAS OBSERVED OR DETECTED SO FAR BY THE
DOPPLER WEATHER RADAR. THE DOMINANT WARM SOUTHERLY WINDS...AND
STRONG SUBSIDENCE ALOFT QUICKLY SUPPRESSED AND LIMITED ANY
CONVECTIVE DEVELOPMENT. THIS SOUTHERLY FLOW HOWEVER ALLOWED
DAYTIME TEMPERATURES TO INCREASE AN ADDITIONAL DEGREE OR TWO IN
THE AFTERNOON...WITH A NEW RECORD HIGH TEMPERATURE BEING SET AT
THE SAN JUAN INTERNATIONAL AIRPORT. THIS OVERALL HOT AND DRY
WEATHER PATTERN IS EXPECTED TO CONTINUE DURING THE NEXT FEW DAYS.

DURING THE OVERNIGHT HOURS...MOSTLY CLEAR AND TRANQUIL WEATHER
CONDITIONS WITH VERY LITTLE OR NO SHOWER ACTIVITY EXPECTED ACROSS
THE REGION. A BRIEF AND LIGHT SHOWER MAY MOVE INLAND ALONG PORTIONS
OF THE SOUTH AND EAST COASTAL SECTIONS BUT ALL IN ALL SHOWER
ACTIVITY WILL BE LIMITED OVER LAND.

ON MONDAY...MOSTLY SUNNY SKIES EXPECTED ONCE AGAIN WITH WARM DAYTIME
TEMPERATURES AND LIMITED OR NO SHOWER ACTIVITY DURING THE DAY. BASED
ON LATED MODEL GUIDANCE ALL SUGGEST NO SIGNIFICANT RAINFALL OR WEATHER
FEATURE EXPECTED TO AFFECT THE REGION FOR THE NEXT SEVERAL DAYS. MOSTLY
FAIR AND STABLE CONDITIONS SHOULD PERSIST FOR MOST OF THE WORK WEEK.

AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS THE LOCAL FLYING
AREA FOR THE NEXT 24 HOUR WITH LITTLE TO NO SIGNIFICANT WX EXPECTED.
SFC WINDS WILL BE FROM THE SOUTH SOUTHEAST AT AROUND 10 KNOTS WITH
SEA BREEZE VARIATIONS UNTIL AROUND 26/22Z...BECOMING LIGHT AND
VARIABLE FOR MOST OF THE TERMINALS THEREAFTER. SOUTHEAST WINDS AT
AROUND 10-15KT EXPECTED ACROSS THE LOCAL AREA AFTER 27/12Z.

MARINE...A GENTLE TO MODERATE SOUTHERLY WIND FLOW OF 15 KNOTS OR
LESS AND SEAS OF 4 FEET OR LESS WILL PERSIST OVERNIGHT AND MONDAY.

SHOWERS ACROSS THESE LOCATIONS...HOWEVER NO SIGNIFICANT RAINFALL
AMOUNTS ARE EXPECTED AT THIS MOMENT.

ONCE AGAIN...MODEL GUIDANCE CONTINUES TO SUGGEST A FAIR AND
STABLE WEATHER PATTERN...UNDER A STRONG MID TO UPPER LEVEL RIDGE.
THE GFS MODEL INDICATES DRY CONDITIONS WITH LIMITED LOW LEVEL
MOISTURE...PARTICULARLY AFTER TUESDAY...AS A RESULT...SHOWER
ACTIVITY...IF ANY...WILL BE SHALLOW AND OF SHORT DURATION. IN
ADDITION...ABNORMALLY WARMER TEMPERATURES WILL CONTINUE AT LEAST
UNTIL WEDNESDAY...AS THE GFS CONTINUES TO FORECAST HIGHER THAN
NORMAL 1000-850MB THICKNESS VALUES WITH WARMER THAN NORMAL 925 MB
TEMPERATURES. THE COMBINATION OF THESE PARAMETERS WITH A SOUTHERLY
WIND FLOW WILL RESULT IN WARMER THAN NORMAL TEMPERATURES ACROSS
THE LOCAL ISLANDS DURING THE NEXT SEVERAL DAYS.

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL ACROSS THE LOCAL FLYING
AREA. AFTER 26/17Z SCT SHRA WITH MTN OBSCURATIONS AND ISOLD MVFR
CONDS WILL DEVELOP ACROSS THE INTERIOR AND NORTHERN SLOPES OF PUERTO
RICO AND ARND TIST. SFC WINDS WILL BE FROM THE SOUTH SOUTHEAST AT
AROUND 10 KNOTS WITH SEA BREEZE VARIATIONS AFTER 26/15Z.


&&

.MARINE...NORTH NORTHEAST SWELLS WILL CONTINUE TO FADE ACROSS
THE LOCAL ATLANTIC TODAY. MARINERS CAN EXPECT...A GENTLE TO
MODERATE SOUTHERLY WIND FLOW OF 15 KNOTS OR LESS AND SEAS BETWEEN
2 AND 4 FEET.

1027 PM AST SAT APR 25 2015

.UPDATE...NO CHANGE TO PREVIOUS DISCUSSION...FORECAST ON TRACK.
A FAIR AND STABLE WEATHER PATTERN WILL CONTINUE TO PREVAIL ACROSS
THE LOCAL ISLANDS OVER THE NEXT SEVERAL DAYS...UNDER A MID TO
UPPER LEVEL RIDGE AND LIMITED LOW LEVEL MOISTURE. SHOWER ACTIVITY...
IF ANY...WILL BE SHALLOW AND FOCUSED EACH AFTERNOON ACROSS THE
NORTHERN SLOPES OF PUERTO RICO. ABOVE NORMAL TEMPERATURES WILL
PREVAIL ACROSS THE AREA...BUT ESPECIALLY ALONG THE NORTHERN SLOPES
AS A SOUTHERLY WIND FLOW PREVAILS.

&&

.AVIATION...MOSTLY VFR CONDITIONS WILL PREVAIL ACROSS THE LOCAL
FLYING AREA UNTIL 26/18Z. AFTER 26/18Z FEW SHRA WITH MTN
OBSCURATIONS WILL DEVELOP ACROSS THE INTERIOR AND NORTHERN SLOPES
OF PUERTO RICO. SFC WINDS WILL BE FROM THE SOUTHEAST AT AROUND 10
KNOTS WITH SEA BREEZE VARIATIONS AFTER 26/16Z.

.PREV DISCUSSION... /ISSUED 303 PM AST SAT APR 25 2015/

SYNOPSIS...STRONG MID-UPPER LEVEL RIDGE WILL MAINTAIN ITS HOLD ACROSS
THE REGION OVER THE NEXT SEVERAL DAYS AND REMAIN THE DOMINANT WEATHER
FEATURE. AT THE SURFACE...WEAKLY INDUCED TROUGH AND HIGH PRESSURE
ACROSS THE ATLANTIC SHIFTING FARTHER EAST ACROSS THE EASTERN
ATLANTIC WILL MAINTAIN FAIRLY LIGHT SOUTHEASTERLY TRADE WINDS
THROUGH EARLY NEXT WEEK.

DISCUSSION...THE DOMINANT RIDGE PATTERN ALOFT WILL HELP SUPPORT
STRONG CAP INVERSION AND CONTINUE TO SUPPRESS/LIMIT CONVECTIVE
DEVELOPMENT ACROSS THE FORECAST AREA. IN ADDITION SATELLITE IMAGERY
AND LATEST GFS MODEL GUIDANCE BOTH SUGGEST NO SIGNIFICANT AMOUNTS
OF MOISTURE TRANSPORT ACROSS THE REGION...UNDER THE PERSISTENT
SOUTHERLY FLOW. THIS FAIRLY DRY SOUTHERLY FLOW IS TO PERSIST THROUGH
THE EARLY PART OF NEXT WEEK. WITH THAT SAID EXPECT MOSTLY SUNNY
AND FAIR WEATHER SKIES TO PREVAIL ACROSS THE REGION. ABNORMALLY
WARMER TEMPERATURES AND OVERALL DRY CONDITIONS ARE FORECAST TO PERSIST
IN SOME AREAS AT LEAST UNTIL TUESDAY OF NEXT WEEK UNDER THE PRESENT
AND EXPECTED DRY SOUTHERLY LOW LEVEL WIND FLOW. A FEW LIGHT SHOWERS
MAY REACH PARTS OF THE SOUTH AND EAST COASTAL SECTIONS OF SOME OF
THE ISLANDS DURING THE LATE EVENING AND OVERNIGHT HOURS FOLLOWED
BY LIMITED SHOWERS DEVELOPMENT EACH DAY.

AVIATION...VFR CONDS WILL PREVAIL DURING THE NEXT 24 HOURS. MTN
OBSCURATIONS ACROSS THE INTERIOR AND NORTHERN SLOPED OF PUERTO RICO
THROUGH THE AFTERNOON. SFC WINDS WILL BE FROM THE SOUTH SOUTHEAST AT
AROUND 10 KNOTS WITH SEA BREEZE VARIATIONS.
