AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
1056 AM EDT MON MAY 27 2013
.UPDATE...
THE MORNING SURFACE ANALYSIS SHOWED THE RIDGE AXIS ORIENTED FROM
EAST TO WEST ACROSS NORTHERN FLORIDA AND THE NORTHERN GULF COAST
STATES WITH MODERATE EASTERLY FLOW STREAMING ACROSS OUR LOCAL
AREA. HIGHER MOISTURE HAS BEGUN TO LIFT NORTH ACROSS THE FLORIDA
STRAITS AND INTO THE SOUTHERN PORTIONS OF THE FLORIDA PENINSULA.
THE LATEST OBSERVATIONS AROUND THE LOCAL AREA SHOWED A DECENT
DEWPOINT GRADIENT ACROSS THE AREA WITH MID TO UPPER 60S AROUND THE
LAKE REGION AND LOWER 70S ACROSS THE SOUTHERN PORTION OF THE
PENINSULA. THE MODEL SOUNDING AT MIA REFLECTS THIS INCREASE WITH A
PRECIPITABLE WATER OF 1.42", WHICH WAS AROUND AN INCH YESTERDAY
EVENING. THE LATEST RADAR LOOP SHOWED THE BEST SHOWER COVERAGE
FARTHER SOUTH OVER THE FLORIDA STRAITS WITH MAINLY ISOLATED
COVERAGE OVER OUR SOUTHERN AREAS OR SOUTH OF A LINE FROM FORT
LAUDERDALE TO NAPLES. THE LATEST HRRR HAS INITIALIZED WELL WITH
THIS COVERAGE AND GENERALLY INDICATES THE BEST AFTERNOON COVERAGE
REMAINING OVER THE INTERIOR AND GULF COAST AREAS WITH THE MODERATE
DEEP EASTERLY FLOW IN PLACE. OUTSIDE OF A FEW MINOR TWEAKS TO THE
GRIDDED FORECAST DATABASE...THE PREVIOUS FORECAST REMAINS ON TRACK
WITH NO MAJOR UPDATES NECESSARY AT THIS TIME.

.PREV DISCUSSION... /ISSUED 648 AM EDT MON MAY 27 2013/
AVIATION...
A STRONG EASTERLY FLOW WILL CONTINUE THROUGH THE TAF PERIOD. THIS
WILL EQUATE TO STRONGER SUSTAINED WINDS DURING THE DAY WITH GUSTS
TO 20 TO 25 KTS IN SOME LOCATIONS. ALSO, THIS WILL BRING INCREASED
MOISTURE AND SCATTERED SHOWERS DEVELOPING MID DAY ACROSS SOUTH
FLORIDA. CURRENT MODELS RUNS SHOW THE MAIN AREA OF SHOWERS SHOULD
BE INLAND AND IN THE FAR SOUTHERN PORTION OF THE AREA. GIVEN THIS,
HAVE REMOVED MENTION OF PRECIPITATION FOR NOW, WITH THE EXCEPTION
OF KTMB WHICH HAS VCSH AFTER 17Z. HOWEVER, THERE DOES REMAIN A
CHANCE FOR SHOWERS ALONG THE ATLANTIC COAST AND THERE IS ALSO A
SLIGHT CHANCE FOR A THUNDERSTORM TO DEVELOP IN THE LATE MORNING
THROUGH THE OVERNIGHT HOURS. HOWEVER, CONFIDENCE IS TOO LOW FOR
EITHER TO MENTION IN TAFS AT THIS TIME.
PREV DISCUSSION... /ISSUED 231 AM EDT MON MAY 27 2013/
SHORT TERM (TODAY THROUGH WEDNESDAY)...
WEAK SYNOPTIC FEATURES WILL AFFECT SOUTH FLORIDA EARLY THIS WEEK WITH
INCREASING MOISTURE AND INSTABILITY. A VERY STRONG SUBSIDENCE CAP
THAT HAS BEEN PERSISTENT THE PAST FEW DAYS WILL RAPIDLY ERODE THIS
MORNING ACCORDING TO FORECAST SOUNDINGS WITH PWAT INCREASING TO NEAR
NORMAL LEVELS FOR LATE MAY. CURRENTLY THIS IS AROUND ONE INCH BUT
WILL BE INCREASING TO AROUND 1.7-1.9 INCHES BY THIS AFTERNOON AND
CONTINUING THROUGH THE END OF THE WEEK. THIS ALREADY SOMEWHAT
EVIDENT FROM RADAR SIGNATURES WITH SCATTERED SHOWER ACTIVITY OVER
THE FLORIDA STRAITS. THERE HAS NOT BEEN ANY LIGHTNING AS YET BUT AS
THE ATMOSPHERE MOISTENS AND DESTABILIZES THERE COULD BE SOME ISOLATED
THUNDER BY THIS AFTERNOON ESPECIALLY OVER THE SOUTHERN PORTIONS. IN
ADDITION, BOTH THE GFS AND ECMWF ARE SHOWING A WEAK MID LEVEL LOW
DEVELOPING OFF THE SOUTHEAST COAST OF THE PENINSULA BY LATE TUESDAY
FURTHER DESTABILIZING CONDITIONS.
AT THE SURFACE, STRONG HIGH PRESSURE OVER THE SOUTHEAST STATES WILL
CONTINUE WHICH WILL RESULT IN A HIGH RISK OF RIP CURRENTS AT ALL OF
THE EAST COAST BEACHES. THIS WILL ALSO MAINTAIN AN INCREASING
SOUTHEAST FLOW WHILE AT THE SAME TIME DEEPENING SO THE STEERING FLOW
FOR CONVECTIVE ACTIVITY WILL BE FROM THE E-SE.
LONG TERM (WEDNESDAY NIGHT THROUGH SUNDAY)...
THE WEAK MID LEVEL TROUGH WILL MOVE LITTLE THROUGH THE END OF THE
WEEK KEEPING THE CHANCES FOR SHOWERS AND THUNDERSTORMS ELEVATED.
SURFACE HIGH PRESSURE WILL ALSO CONTINUE TO STRETCH FROM THE
ATLANTIC TO THE SOUTHEAST STATES AND THIS WILL RETAIN HIGH CHANCES
FOR RIP CURRENTS AT THE ATLANTIC BEACHES THROUGHOUT THE EXTENDED
PERIOD.
MARINE...
PERSISTENT EASTERLY WIND OF 15 TO 20 KNOTS AND OCCASIONALLY HIGHER
WILL KEEP SEAS ELEVATED THROUGH THE WEEK.
FIRE WEATHER...
DEEP TROPICAL MOISTURE WILL RETURN TO SOUTH FLORIDA TODAY AND
CONTINUE THROUGH THE WEEK.

THUNDERSTORMS: THERE IS A SLIGHT CHANCE OF THUNDERSTORMS FROM THIS AFTERNOON THROUGH THE OVERNIGHT HOURS. WIND: GUSTY WIND OF UP TO 30 MPH IS POSSIBLE WITH ANY THUNDERSTORMS THAT ARE ABLE TO DEVELOP. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY A HIGH RISK OF RIP CURRENTS WILL CONTINUE ALONG THE ATLANTIC BEACHES THROUGH AT LEAST FRIDAY. STRONG RIP CURRENTS ARE LIKELY, MAKING CONDITIONS VERY DANGEROUS FOR SWIMMING. THUNDERSTORMS WITH GUSTY WINDS AND LOCALLY HEAVY RAINFALL ARE POSSIBLE ACROSS SOUTHEAST FLORIDA TUESDAY. ALTHOUGH SEVERE THUNDERSTORMS ARE NOT ANTICIPATED, INCREASING INSTABILITY AND STRENGTHENING LOW LEVEL WINDS COULD ALSO RESULT IN LOCALIZED STRONG WIND GUSTS IN THE STRONGEST STORMS WHICH MOVE ONSHORE THE ATLANTIC COAST. A WET AND STORMY PATTERN COULD PREVAIL INTO LATE THIS WEEK. HOWEVER, THE FORECAST REMAINS UNCERTAIN AND WILL CONTINUE TO BE MONITORED. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WILL NOT BE NEEDED. FOR MORE INFORMATION...VISIT THE NATIONAL WEATHER SERVICE IN MIAMI WEBSITE AT WWW.WEATHER.GOV/MIAMI.
The national radar mosaic for the moment the first event began.
2 rip current. Local standard time, as filed.
A fifteen-year-old boy drowned at John U. Lloyd State Park due to rip currents. The beach was unguarded but red rip current warning flags were posted at the entrance to the park.
A woman was taken to Jupiter Medical Center after a near-drowning at Dubois Park in Jupiter.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
