The episode as NWS TBW wrote it up.
Moist and unstable southwest flow was established at the surface and aloft. In addition, a series of upper disturbances were moving over the area. When combined with daytime heating and sea breeze boundaries, this allowed for numerous strong to severe thunderstorms to develop through the day and continue into the evening, with damaging winds, hail, and a waterspout occurring with the stronger storms.
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 Tampa Bay, FL wrote its last area forecast discussion before the first event at Jun 3, 12:09 PM EST, 1 hour 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 109 PM EDT THU JUN 3 2010 .SHORT TERM (TONIGHT - SATURDAY)...UPPER TROUGH OVER THE WESTERN GULF COMBINED WITH UPPER/SURFACE RIDGING ACROSS THE SOUTHERN PENINSULA AND GULF WILL MAINTAIN A DEEP LAYERED SOUTHWEST WIND FLOW OVER THE ENTIRE FORECAST AREA DURING THE SHORT TERM PERIOD. DIURNAL AFTERNOON STORMS SOME POSSIBLY STRONG TO SEVERE WILL GRADUALLY WIND DOWN OVER INTERIOR SECTIONS BY MID TO LATE EVENING TONIGHT AS THE SEA BREEZE CIRCULATIONS COLLAPSE AND LOSS OF DAYTIME HEATING TAKES PLACE. THEREAFTER EXPECT ADDITIONAL SHOWERS AND STORMS (POPS 30 PERCENT) TO DEVELOP OVER THE ADJACENT GULF WATERS OVERNIGHT WITH THIS CONVECTION MOVING ONSHORE AND AFFECTING COASTAL ZONES BY EARLY FRIDAY MORNING. DURING FRIDAY LITTLE CHANGE IS EXPECTED. ABUNDANT MOISTURE COMBINED WITH THE SEA BREEZE CIRCULATIONS WILL FAVOR SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS OVER THE FORECAST AREA WITH DEEP LAYERED SOUTHWEST STEERING FLOW FAVORING CONVECTION ALONG THE COASTAL LOCATIONS DURING THE EARLY MORNING HOURS...THEN SHIFTING EAST WITH THE HIGHEST POPS AND BEST AREAL COVERAGE OF STORMS AGAIN SETTING UP OVER INLAND LOCATIONS DURING THE AFTERNOON AND EARLY EVENING HOURS. ON SATURDAY SLIGHTLY DRIER MID LEVEL AIR ADVECTING IN FROM THE WEST (VIA MODEL CROSS SECTIONS) ALONG WITH A SUBTLE INCREASE IN SUBSIDENCE FROM THE BUILDING UPPER RIDGE OVER THE SOUTHERN PENINSULA MAY RESULT IN SLIGHTLY LOWER RAIN CHANCES POPS 30 TO 40 PERCENT RANGE COAST TO INLAND LOCATIONS. THE ONSHORE FLOW WILL FAVOR ABOVE NORMAL OVERNIGHT MIN TEMPERATURES ALONG THE COAST AND OVER INLAND LOCATIONS EACH AFTERNOON WITH HIGHS CLIMBING INTO THE UPPER 80S ALONG THE COAST AND LOWER TO MID 90S INLAND WITH OVERNIGHT LOWS IN THE MID 70S INLAND AREAS...AND UPPER 70S TO AROUND 80 ALONG THE IMMEDIATE COAST. THE ABOVE NORMAL TEMPERATURES COMBINED WITH HIGH HUMIDITY VALUES WILL LIKELY LEAD TO INCREASING HEAT INDICES AS WE MOVE INTO THE UPCOMING WEEKEND WITH UNCOMFORTABLE OUTDOOR CONDITIONS EXPECTED. .LONG TERM (SATURDAY NIGHT - THURSDAY)...MODELS ARE SIMILAR SATURDAY NIGHT THROUGH MONDAY AS MID-LEVEL RIDGING BUILDS ACROSS THE GULF OF MEXICO WITH WEAK TROUGHING REMAINING ALONG THE EAST COAST. AFTER MONDAY...THE GFS KEEPS A BIT MORE TROUGHING JUST OFF THE FLORIDA COAST WHILE THE ECMWF HAS A FLATTER...MORE PROGRESSIVE FLOW TO OUR NORTH. THESE DIFFERENCES DO IMPACT OUR OVERALL CHANCES FOR STORMS EACH AFTERNOON. THE GFS SOLUTION IS WETTER WITH A WEAK SURFACE BOUNDARY NEARBY AND CONTINUED WEAK CYCLONIC FLOW ALOFT. THE ECMWF IS DRIER WITH THE BOUNDARY WELL TO THE NORTH AND HIGH PRESSURE BUILDING IN. BEST BET AT THIS POINT IS TO CONTINUE TO LEAN TOWARD CLIMATOLOGY WHICH IS 30 TO 40 PERCENT RAIN CHANCES DURING THE AFTERNOON HOURS. THE 06Z GFS REALLY PARTS WAYS WITH THE ECMWF BY THURSDAY WITH A DEEP EASTERN U.S. TROUGH DIGGING INTO THE EASTERN GULF WHILE THE ECMWF KEEPS DEEP-LAYERED RIDGING OVERHEAD. SINCE BOTH MODELS FORECAST THE RIDGE TO DEVELOP THROUGH WEDNESDAY...GOING TO KEEP IT THERE ANOTHER DAY UNTIL MODELS REACH A CONSENSUS ON THIS SIGNIFICANT CHANGE. && .AVIATION...EXPECT MORE CONVECTIVE ACTIVITY NEAR THE TERMINALS THAN YESTERDAY AS THE SEA BREEZE DEVELOPS AND MOVES INLAND. FOCUS SHOULD SHIFT TO THE EAST OF THE TERMINALS BY MID AFTERNOON WITH VFR AFTER THAT. && .MARINE...SURFACE RIDGE AXIS ACROSS THE SOUTHERN PENINSULA WILL MAINTAIN A SOUTH TO SOUTHWEST WIND FLOW AROUND 10 KNOTS WITH SEAS OF 2 TO 3 FEET OVER THE GULF WATERS THROUGH THE FORECAST PERIOD WITH HIGHER WIND AND SEAS EXPECTED IN THE VICINITY OF THUNDERSTORMS EACH DAY. && .FIRE WEATHER...AMPLE LOW LEVEL MOISTURE AND RAIN CHANCES WILL KEEP HUMIDITY VALUES WELL ABOVE CRITICAL LEVELS THROUGH THE END OF THE WEEKEND AND INTO THE UPCOMING WEEKEND WITH NO FIRE WEATHER ISSUES EXPECTED. && .PRELIMINARY POINT TEMPS/POPS...
