The episode as NWS MFL wrote it up.
A fourth consecutive day of severe weather occurred over parts of South Florida as the area remained under a very unstable atmosphere.
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 May 28, 8:37 AM EST, 3 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 937 AM EDT THU MAY 28 2009 .UPDATE...IMPRESSIVE MCS RACED OFF THE TEXAS COAST AND ACROSS THE GULF OF MEXICO OVERNIGHT. THIS FEATURE IS OVER THE EASTERN GULF BUT CLOUD TOPS HAVE WARMED SIGNIFICANTLY OVER THE PAST FEW HOURS. HIGH CIRRUS IS BEGINNING TO BLOW ACROSS THE AREA. HOWEVER...THERE ARE BREAKS AND SO ENOUGH HEATING IS ANTICIPATED TODAY TO RESULT IN ANOTHER ACTIVE AFTERNOON. A FEW STORMS HAVE ALREADY DEVELOPED ALONG THE MAINLAND MONROE COAST. ADDITIONAL STORMS ARE EXPECTED TO DEVELOP NEAR THE GULF COAST WITH STORMS DEVELOPING INLAND AND EVENTUALLY CONSOLIDATING ALONG THE ATLANTIC COAST AS ACTIVITY CONVERGES WITH A DEVELOPING ATLANTIC SEA BREEZE THIS AFTERNOON. STRONGER SW LOW LEVEL WINDS SHOULD DELAY THE SEA BREEZE LATER THIS AFTERNOON AND CLOSER TO THE COAST. WILL BE MONITORING THE PROGRESSION OF THE DISSIPATING MCS OVER THE EASTERN GULF...BUT RIGHT NOW A TYPICAL DIURNAL CONVECTIVE DAY IS EXPECTED. THE MORNING MIAMI SOUNDING SHOWS AN UNSTABLE ATMOSPHERE. ALTHOUGH MID LEVELS HAVE WARMED WITH AN H5 TEMP OF -8.7...MAX AFTERNOON CAPE CONTINUES >3000 J/KG...LI IS AROUND -7C...AND IT IS A BIT MORE MOIST TODAY WITH A PWAT OF 1.76 INCHES. SO THINGS LOOK ON TRACK FOR ANOTHER ACTIVE DAY WITH STRONG TO EVEN A FEW SEVERE THUNDERSTORMS POSSIBLE. THERE IS DECENT TURNING OF THE WINDS IN THE LOWER LEVELS...AND THIS COULD LEAD TO THE POSSIBILITY OF A TORNADO BRIEFLY SPINNING UP AS STORMS DEVELOP/ENCOUNTER THE ATLANTIC SEA BREEZE...SO WE WILL ADD THIS MENTION TO THE HAZARDOUS WEATHER OUTLOOK. /DG && .PREV DISCUSSION... /ISSUED 732 AM EDT THU MAY 28 2009/ AVIATION...E COAST TERMINALS VFR E COAST TERMINALS THRU 16Z.

JR/AT PREV DISCUSSION... /ISSUED 337 AM EDT THU MAY 28 2009/ DISCUSSION...I MUST SAY THIS STRETCH OF MIDNIGHT SHIFTS HAS BEEN A CHALLENGE AND TONIGHT IS NO EXCEPTION. THE GFS CONTINUES TO SUFFER FROM CONVECTIVE FEEDBACK AND IS VERY ERRATIC WITH THE POP NUMBERS. THE MET HAS OUTPERFORMED THE MAV ALL WEEK SO AGAIN WILL GO MUCH HIGHER THAN MAV GUIDANCE TODAY. THE REAL CONCERN IS THE LINE OF TSRA IN THE CENTRAL GULF OF MEXICO AND CURRENTLY AT 07Z IS HOLDING ITS OWN. IN FACT, AT ONE TIME DURING THE NIGHT THE CLOUD TOPS BEGAN TO WARM BUT THEY ARE ONCE AGAIN COOLING AND IT HAS DEVELOPED A VERY NICE BOW FEATURE. THE NAM WAS THE ONLY MODEL TO CATCH ON TO THIS FEATURE AND BROUGHT IT TO JUST OFF THE SOUTHWEST COAST OF FLORIDA BY 12Z THIS MORNING BUT AT A CONSIDERABLY WEAKER STATE. HOWEVER, IT HAS NOT BEGUN TO WEAKEN AS OF THIS WRITING AND THIS COULD REALLY HAMPER THE FORECAST CONDITIONS ACROSS THE REGION. A FEW SCENARIOS COME TO MIND. THIS LINE OF CONVECTION COULD HOLD TOGETHER AND THE POPS FOR THE WEST COAST WILL TURN OUT TO BE TOO LOW AND IT COULD ALSO AFFECT FORECAST TEMPERATURES. ANOTHER SOLUTION WOULD BE THAT THE NAM TURNS OUT TO BE CORRECT AND IT DOES WEAKEN BUT A SHIELD OF DENSE DEBRIS CLOUDS COULD SPREAD ACROSS THE REGION AND INHIBIT DIURNAL HEATING ENOUGH THAT THE POPS WOULD BE TOO HIGH. IF THIS CONVECTIVE CLUSTER DOES HOLD TOGETHER, IT WOULD REACH THE GULF COAST WATERS AROUND 13Z OR 14Z SO AT THAT TIME IT COULD BE DETERMINED WHAT IMPACT IT MIGHT HAVE ON THE REMAINDER OF THE DAY. SO DEFINITELY SOME UNCERTAINTY TO TODAYS FORECAST BUT SINCE WESTERLY FLOW IS CONTINUING WILL GO ALONG WITH WHAT HAS ALREADY BEEN ADVERTISED AND THAT IS TO SAY WIDESPREAD CONVECTION DEVELOPING OVER INTERIOR SOUTH FLORIDA AND THEN MOVING TO THE EAST COAST METRO AREA BY THIS AFTERNOON. THEN A REPEAT PERFORMANCE IS HIGHLY LIKELY FOR FRIDAY AND SATURDAY AFTERNOONS. IN THE EXTENDED, THE MODELS HAVE BEEN STRUGGLING JUST HOW MUCH PUSH THE TROUGH THAT HAS BRINGING US THE WET WEATHER WILL EVENTUALLY HAVE AND HAVE BEEN BOUNCING AROUND WITH THE NOTION OF A TROUGH BOUNDARY MOVING INTO SOUTH FLORIDA BRINGING SOME DRYING ALONG WITH IT. UNTIL WE SEE MORE CONSISTENCY FROM RUN TO RUN WILL NOT CHANGE MUCH IN THE EXTENDED. IT DOES APPEAR HOWEVER THAT AS TIME GOES ON SURFACE HIGH PRESSURE WILL SLOWLY BUILD BACK INTO THE AREA AND THE PATTERN WILL GO BACK TO CONVECTION DEVELOPING ALONG SEA BREEZE CONVERGENCE BOUNDARIES AND AFFECT MOSTLY THE AREAS AWAY FROM BOTH COASTS. MARINE...WEAK PRESSURE GRADIENT WILL CONTINUE AND WITH RIDGE REMAINING OVER THE FLORIDA KEYS A SOUTHWEST WIND OF LESS THAN 15 KNOTS WILL DOMINATE WITH SEAS LESS THAN 4 FEET THROUGH THE PERIOD.

MOST ACTIVITY WILL AFFECT THE EAST COAST AND LAKE OKEECHOBEE REGION. LOCALLY HEAVY RAINS, FREQUENT LIGHTNING STRIKES, GUSTY WINDS, AND POSSIBLY HAIL CAN BE EXPECTED. ISOLATED THUNDERSTORMS WILL ALSO BE POSSIBLE ALONG THE WEST COAST. THESE STORMS MAY BE ACCOMPANIED WITH OCCASIONAL LIGHTNING AND A BRIEF HEAVY DOWNPOUR.

HAIL: NICKEL-SIZED HAIL WILL BE POSSIBLE IN THE STRONGEST THUNDERSTORM ACTIVITY OVER THE CENTRAL INTERIOR, LAKE OKEECHOBEE REGION, AND EAST COAST. FLOODING: THE THUNDERSTORMS WILL BE CAPABLE OF PRODUCING VERY HEAVY RAIN IN A SHORT PERIOD OF TIME. WITH SOILS ALREADY SATURATED FROM PREVIOUS RAINS THE PAST FEW DAYS, THIS COULD LEAD TO LOCALIZED FLOODING OF LOW LYING AND FLOOD PRONE AREAS ESPECIALLY IN THE EAST COAST METRO. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED EACH AFTERNOON THROUGH THE COMING WEEK WITH SOME ISOLATED STRONG TO POSSIBLY SEVERE STORMS POSSIBLE THROUGH THE END OF THIS WEEK. .SPOTTER INFORMATION STATEMENT...
