The episode as NWS MFL wrote it up.
Typical summer sea breeze thunderstorm activity was enhanced by strong instability to produce isolated strong to severe thunderstorms across southeast Florida.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Miami, FL wrote its last area forecast discussion before the first event at Jun 13, 1:56 PM EST, 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 256 PM EDT SAT JUN 13 2009 .DISCUSSION... OVERALL...EXPECT SIMILAR CONDITIONS TO THE PAST SEVERAL AFTERNOONS TO OCCUR ACROSS SOUTH FLORIDA ONCE AGAIN TODAY...WITH EARLY AFTERNOON VISIBLE SATELLITE IMAGERY INDICATING THE DEVELOPMENT OF ENHANCED CUMULUS CLOUDS ACROSS THE SOUTHERN 2/3RDS OF THE FORECAST AREA. AFTERNOON CONVECTION SHOULD ONCE AGAIN BE FOCUSED ALONG INLAND MOVING ATLANTIC/GULF COAST SEA BREEZES AND LAKE BREEZE... WITH NORTH/NORTHEASTERLY STEERING FLOW ALLOWING SHOWERS/STORMS THAT DEVELOP IN THIS REGION TO SPREAD SOUTH-SOUTHWESTWARD. HOWEVER...ONE SUBTLE CHANGE FROM PREVIOUS DAYS IS THAT THE LOWER /MID-LEVEL RIDGE AXIS HAS APPARENTLY SHIFTED A BIT FURTHER TO THE SOUTH TODAY...PLACING THE NORTHERN THIRD OF THE AREA IN A LIGHT WESTERLY STEERING FLOW. FOR THIS REASON...WILL MAINTAIN SLIGHTLY HIGHER AFTERNOON RAIN CHANCES ACROSS THE NORTHEAST QUADRANT OF THE FORECAST AREA AS WELL. A POTENTIALLY MORE SIGNIFICANT FEATURE OF INTEREST WILL ENTER THE FORECAST PICTURE TONIGHT...AS SHORT TERM MODELS NOW SUGGEST THAT A WELL-DEFINED MID-LEVEL SHORTWAVE TROUGH -- CURRENTLY SEEN IN WATER VAPOR DATA ACROSS ALABAMA/GEORGIA -- WILL MOVE SOUTHEASTWARD AROUND NORTHEASTERN FLANK OF MID-LEVEL ANTICYCLONE CENTERED ACROSS SOUTH TEXAS. NOT ONLY WILL THIS FEATURE OFFER MORE LARGE SCALE SUPPORT FOR UPWARD VERTICAL MOTIONS NECESSARY TO MAINTAIN AFTERNOON CONVECTION...BUT ITS APPROACH WILL ALSO BACK STEERING FLOW TO THE NORTH-NORTHWEST...ALLOWING ANY EVENING/NOCTURNAL CONVECTIVE ACTIVITY ACROSS CENTRAL FLORIDA TO AFFECT THE REGION FROM LAKE OKEECHOBEE TO THE PALM BEACH COAST...AND WILL LEAVE SLIGHT CHANCE POPS ACROSS THIS AREA. ALTHOUGH ALL GUIDANCE INDICATES THAT THIS SHORTWAVE TROUGH WILL WEAKEN AS IT DRIFTS ACROSS SOUTH FLORIDA TOMORROW...THE PRESENCE OF ITS REMNANTS WILL RESULT IN LOWER HEIGHTS ALOFT...AND A CONTINUATION OF NNW STEERING FLOW WILL LIKELY MEAN A MORE ACTIVE DAY OF THUNDERSTORM ACTIVITY ALONG THE SOUTHEAST ATLANTIC COAST OF THE PENINSULA. ASIDE FROM LINGERING ACTIVITY ON SUNDAY EVENING...EXPECT GENERALLY QUIET CONDITIONS TO PREVAIL OVERNIGHT. THE POTENTIAL DOES EXIST FOR A REPEAT PERFORMANCE ON MONDAY...AS ANOTHER WEAK MID-LEVEL WAVE MAY MOVE ACROSS SOUTH FLORIDA IN DIFFLUENT N/NW FLOW ALOFT. WILL BE MAKING NO CHANGES TO THE EXTENDED PORTION OF THE FORECAST AT THIS TIME...AS GLOBAL MODELS CONTINUE TO SHOW SIMILAR PATTERNS FROM TUESDAY THROUGH SATURDAY. ALL GUIDANCE INDICATES THAT THE MID-LEVEL RIDGE OVER THE NORTHERN GULF/SOUTHERN PLAINS WILL RETROGRADE SLIGHTLY DURING THE BEGINNING OF THE EXTENDED PERIOD...AS A STRONG UPPER TROUGH DEVELOPS OVER THE PACIFIC COAST. THIS MAY SERVE TO INCREASE RAIN CHANCES DURING THIS PERIOD...AS SUBSIDENT INFLUENCES OF THE RIDGE MAY BE DIMINISHED...AND STRONG NORTHERLY FLOW WILL UNDOUBTEDLY BRING ADDITIONAL IMPULSES ALOFT SOUTHWARD OVER THE AREA. TOWARD THE END OF THE WEEK...THE GFS DEVELOPS A STRONGER UPPER TROUGH OVER THE GREAT LAKES REGION AND NORTHEAST U.S. AND CONSEQUENTLY MAINTAINS HIGHER RAIN CHANCES FOR SOUTH FLORIDA...WITH THE ECMWF INDICATING MORE RIDGING REMAINING ACROSS THE REGION. THE PREVIOUS FORECAST HAS THIS TREND ESTABLISHED...AND HAVE NO REASON TO MAKE ANY CHANGES AT THIS TIME. && .MARINE... WINDS ACROSS THE LOCAL WATERS THROUGH THE SHORT TERM PORTION OF THE MARINE FORECAST WILL RANGE FROM SOUTH AROUND 10 KNOTS IN THE ATLANTIC...TO WEST-SOUTHWEST AT 5 KNOTS OR LESS ACROSS THE SOUTHEASTERN GULF. THIS WILL RESULT IN PREVAILING SEAS OF 2-3 FEET IN THE ATLANTIC WATERS AND 1-2 FEET IN THE GULF...OUTSIDE OF SHOWER/THUNDERSTORM ACTIVITY...WHICH COULD OCCUR AT ANY TIME. AS MENTIONED BY PREVIOUS FORECASTER...LIGHT WINDS IN THE LOWER TROPOSPHERE WILL PROMOTE AN ENHANCED THREAT FOR WATERSPOUTS ALONG ANY CLOUD CONVERGENCE BANDS...ESPECIALLY ACROSS THE ATLANTIC. && .FIRE WEATHER... MINIMUM AFTERNOON RH VALUES WILL LIKELY CONTINUE TO FALL INTO THE 40-45 PERCENT RANGE ACROSS MUCH OF THE INTERIOR PENINSULA THROUGH THE MIDDLE OF NEXT WEEK...AS TEMPERATURES WARMING INTO THE UPPER 90S LEAD TO DEEP BOUNDARY LAYER MIXING. && .PRELIMINARY POINT TEMPS/POPS...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA. .DAY ONE...TODAY AND TONIGHT THUNDERSTORMS: SCATTERED THUNDERSTORMS ARE EXPECTED AGAIN THIS AFTERNOON AND EVENING. FREQUENT LIGHTNING STRIKES, LOCALLY HEAVY RAINFALL MAY OCCUR WITH SOME STORMS ACROSS THE SOUTHWEST COAST OR INTERIOR, HOWEVER AN ISOLATED SEVERE STORM ACROSS THE INTERIOR MAY PRODUCE SMALL HAIL AND WIND GUSTS UP TO 60 MPH. WATERSPOUTS: THE WINDS IN THE LOWER AND MID LEVELS OF THE ATMOSPHERE ALONG WITH LINGERING BOUNDARIES WILL HELP TO POSSIBLY PRODUCE A FEW WATERSPOUTS OVER THE GULF OF MEXICO AND THE ATLANTIC OCEAN. WIND: THE STRONGEST STORMS WILL PRODUCE BRIEF WIND GUSTS BETWEEN 50 AND 60 MPH ACROSS THE INTERIOR AND WESTERN SECTIONS THIS AFTERNOON. HAIL: HAIL UP TO PENNY SIZE IN DIAMETER WILL BE POSSIBLE WITH THE STRONGEST THUNDERSTORMS THIS AFTERNOON AND EVENING, MOST LIKELY ACROSS INTERIOR AND WESTERN SECTIONS OF MAINLAND SOUTH FLORIDA. FLOODING: URBAN FLOODING MAY BECOME A PROBLEM WITH SLOW MOVING THUNDERSTORMS OVER THE INTERIOR AND WESTERN SECTIONS THIS AFTERNOON. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY THUNDERSTORMS WILL CONTINUE DAILY THROUGH NEXT WEEK. LIGHTNING STRIKES, LOCALLY HEAVY RAINFALL AND GUSTY WINDS WILL BE THE PRIMARY THREATS WITH THIS ACTIVITY. THERE WILL ALSO BE THE LINGERING THREAT OF WATERSPOUTS THROUGH EARLY NEXT WEEK IN THE GULF OF MEXICO AND THE ATLANTIC DUE TO LIGHT WINDS IN THE LOWER AND MID LEVELS OF THE ATMOSPHERE. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED ACROSS INTERIOR LOCATIONS. FOR MORE INFORMATION...VISIT THE NATIONAL WEATHER SERVICE IN MIAMI WEBSITE AT WWW.WEATHER.GOV/MIAMI.
