NATIONAL WEATHER SERVICE MIAMI FL
1016 AM EDT FRI MAY 31 2013
.UPDATE...
NO CHANGES WERE REQUIRED TO THE CURRENT FORECAST. THE 12Z SOUNDING
INDICATED THAT TROPICAL MOISTURE CONTINUES ACROSS THE REGION WITH
A PWAT JUST OVER TWO INCHES WHICH IS ABOUT 20 PERCENT ABOVE THE NORMAL
PWAT FOR THIS DATE. THE FORECAST FOR THE REST OF TODAY IS IN LINE
WITH THE LATEST MESO-SCALE MODEL GUIDANCE INDICATING THAT THE MOST
ACTIVE PERIOD FOR SHOWERS/THUNDERSTORMS WILL BE THIS AFTERNOON
WITH MOST OF THE COVERAGE EXPECTED ACROSS THE WESTERN PORTIONS OF
THE PENINSULA AFTER 18Z THIS AFTERNOON. THE GUIDANCE ALSO CONTINUES
TO INDICATE THAT THE PRESSURE GRADIENT AND RESULTANT STRONG WINDS
ACROSS THE ATLANTIC WATERS WILL CONTINUE TO SLOWLY DECREASE AS
THE DAY PROGRESSES WITH THE SMALL CRAFT ADVISORY FOR THE ATLANTIC
WATERS AND BISCAYNE BAY EXPIRING AFTER 00Z THIS EVENING...WHICH IS
IN LINE WITH CURRENT OBSERVATION TRENDS.

AVIATION...
A BERMUDA CONTINUES TO CONTROL THE WEATHER PATTERN OVER SOUTH
FLORIDA FOR AT LEAST ANOTHER DAY OR TWO. THIS WILL KEEP EAST TO
SOUTHEASTERLY WINDS IN THE FORECAST THROUGH THE TAF PERIOD. IT
WILL ALSO KEEP SHOWERS IN THEM AS WELL. SOME MODELS ARE SUGGESTING
THAT THE PRECIPITATION WILL MOVE OFF TO THE WESTERN SIDE OF THE
STATE, AND BE ENHANCED AS IT REACHES THE GULF COAST. THUS, HAVE
TAKEN MENTION OF RAIN OUT FOR NOW AFTER 19Z, EXCEPT AT KAPF, WHERE
IT IS QUIET NOW AND ADDED RAIN AFTER 18Z. THERE IS ALSO A CHANCE
FOR THUNDERSTORMS THIS AFTERNOON ALONG THE GULF COAST. WITH ANY OF
THE HEAVIER SHOWERS, MVFR AND IFR WILL BE POSSIBLE FOR BRIEF
PERIOD OF TIME.
PREV DISCUSSION... /ISSUED 249 AM EDT FRI MAY 31 2013/
SHORT TERM (TODAY THROUGH SUNDAY)...
MODELS CONTINUE TO HAVE ISSUES WITH THE SURFACE PRESSURE PATTERNS
BUT ARE IN GOOD AGREEMENT WITH THE MID LEVELS. A WEAK PRESSURE
PATTERN ALOFT IS FORECAST TO CONTINUE WITH ABUNDANT DEEP LAYER
MOISTURE IN PLACE WITH PWAT VALUES HOVERING AROUND TWO INCHES. AT
THE SURFACE, THE GFS HAS TRENDED WITH THE ECMWF IN CONTINUING THE
HIGH PRESSURE OVER THE SOUTHEAST STATES BUT SHIFTING IT TO THE
EAST OVER THE WEEKEND AS A WEAK COLD FRONT MOVES INTO THE
SOUTHEAST STATES. THIS WILL RESULT IN RETAINING A STRONG SOUTHEAST
LOW LEVEL FLOW TODAY AND THEN DIMINISHING SATURDAY AND SUNDAY.
THE NAM SEEMS TO BE SUFFERING FROM SOME OF ITS MESOSCALE BIASING
AS IT DEVELOPS A INVERTED TROUGH ALONG THE WEST COAST OF THE
PENINSULA VEERING THE LOW LEVEL FLOW TO THE SOUTH ACROSS OUR
REGION. THE GFS AND ECMWF RETAIN THE THE SOUTHEAST FLOW AND THIS
SEEMS MORE REASONABLE. SO THE HIGH RISK OF RIP CURRENTS WILL
CONTINUE TODAY AND SATURDAY WITH A LESSER THREAT ON SUNDAY BUT
LIKELY MAINTAINING A MODERATE RISK.
THE MAV AND MET GUIDANCE IS NEARLY IN PERFECT AGREEMENT WITH
LIKELY POPS TODAY AND SUNDAY WITH A LESSER CHANCE ON SUNDAY.
HOWEVER, RADAR SIGNATURES ARE NOT TERRIBLY IMPRESSIVE CURRENTLY
AND THE SHORT TERM HIGH RESOLUTION MODELS ARE NOT IN AGREEMENT ON
THE EVOLUTION TOWARDS SUNRISE INTO THE EARLY MORNING. BOTH THE
HRRR AND THE WRF HAVE INITIALIZED WELL IN DEPICTING FAST MOVING
SHOWERS OVER THE ATLANTIC AND MOVING ONSHORE ALONG THE SOUTHEAST
COAST. THE WRF THEN FLARES UP CONVECTION ALONG THE NORTHERN
BROWARD AND PALM BEACH COASTS AROUND 09Z AND DEVELOPS HEAVY
SHOWERS OVER MUCH OF EASTERN PALM BEACH COUNTY. THE HRRR ON THE
OTHER HAND KEEPS THE SHOWERS MINIMAL AND THEN CLEARS OUT THE EAST
COAST DURING THE MORNING WITH ADDITIONAL ACTIVITY DEVELOPING OVER
THE WESTERN HALF IN THE LATE MORNING AS THEY MOVE TOWARDS COASTAL
COLLIER COUNTY. GIVEN THE STATE OF THE CURRENT ATMOSPHERE AND THE
HIGHER RELIABILITY OF THE HRRR, WILL UNDERCUT THE POPS BY AROUND
ONE CATEGORY FROM GUIDANCE.
LONG TERM (SUNDAY NIGHT THROUGH THURSDAY)...
THE GFS AND ECMWF ARE BOTH IN GOOD AGREEMENT IN THE EXTENDED
PERIOD IN MAINTAINING A MOIST AND UNSTABLE ENVIRONMENT OVER SOUTH
FLORIDA WITH WEAK PRESSURE PATTERNS BOTH AT THE SURFACE AND ALOFT.
THIS WILL RESULT IN A MORE TYPICAL SEA BREEZE DRIVEN CONVECTION
PATTERN DURING THE AFTERNOONS AND EVENINGS WITH SLOW STORM MOTION.
AVIATION...
ATLANTIC SHOWERS WILL CONTINUE MOVE ONSHORE THROUGH THE MORNING
ALONG THE EAST COAST AND THEN TRANSITION TOWARDS KAPF DURING THE
AFTERNOON. THERE COULD BE A FEW THUNDERSTORMS ALONG THE WEST COAST
THIS AFTERNOON BUT COVERAGE DOES NOT WARRANT MENTION IN THE TAF AT
THIS TIME. EAST WIND CONTINUES TO BE MODERATE THIS MORNING BUT THE
GRADIENT WILL BEGIN TO RELAX THIS AFTERNOON BUT STILL EXPECTED TO
BE STRONG ENOUGH TO INHIBIT SEA BREEZE DEVELOPMENT ALONG THE
COLLIER COUNTY COAST.
MARINE...
MARINE CONDITIONS WILL CONTINUE TO BE ROUGH ESPECIALLY ALONG THE
ATLANTIC SIDE WITH SCA IN EFFECT. THE SCA WILL BE EXTENDED INTO
THIS AFTERNOON WITH THESE CONDITIONS SLOWLY BEGINNING TO SUBSIDE
OVER THE WEEKEND AS THE HIGH PRESSURE SHIFTS TO THE EAST AND THE
GRADIENT WEAKENS.
FIRE WEATHER...
AMPLE TROPICAL MOISTURE SO NO PROBLEMS OR CONCERNS.

THUNDERSTORMS: ISOLATED THUNDERSTORMS ARE POSSIBLE TODAY OVER THE ATLANTIC WATERS AND EASTERN HALF OF SOUTH FLORIDA.

WIND: WINDS AROUND 20 KTS ARE EXPECTED ACROSS THE ATLANTIC WATERS. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY A HIGH RISK OF RIP CURRENTS WILL CONTINUE ALONG THE ATLANTIC BEACHES THROUGH AT TOMORROW. STRONG RIP CURRENTS ARE LIKELY, MAKING CONDITIONS VERY DANGEROUS FOR SWIMMING. THUNDERSTORMS WITH GUSTY WINDS AND LOCALLY HEAVY RAINFALL ARE POSSIBLE ACROSS SOUTHEAST FLORIDA THROUGH AT LEAST THE BEGINNING OF NEXT WEEK. ALTHOUGH SEVERE THUNDERSTORMS ARE NOT ANTICIPATED, THERE IS ALWAYS A SLIGHT CHANCE OF A THUNDERSTORM BECOMING SEVERE IF CONDITIONS BECOME CONDUCIVE TO ENHANCED DEVELOPMENT. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION IS NOT ANTICIPATED. 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.
1 rip current. Local standard time, as filed.
A 17-year-old young man went missing at the Gulf Stream Park Beach in Boynton Beach, presumed to be swept away by a rip current. Rescue efforts both Friday afternoon and Saturday were unsuccessful and the Coast Guard suspended its search efforts a few days later.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
