The episode as NWS MLB wrote it up.
Several storms formed along the east coast sea breeze as a frontal boundary pushed south across northeast Florida, bringing an increase in moisture and lift. One of these storms became strong near Fellsmere and produced hail up to the size of nickels.
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 Melbourne, FL wrote its last area forecast discussion before the first event at May 7, 1:15 PM EST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 215 PM EDT MON MAY 7 2012 .DISCUSSION... ...FEW STRONG/ISOLATED PULSE SEVERE STORMS EXPECTED INTO THIS EVENING... CURRENT-TONIGHT...WEAK FRONTAL BOUNDARY HAS CREPT INTO OUR NORTHERN FORECAST ZONES. EARLY ONSET OF THE EAST COAST SEA BREEZE FROM THE CAPE NORTHWARD HAS TRANSITIONED WINDS TO EAST OR NORTHEAST. WINDS SOUTH OF THE CAPE WILL BECOME EAST OR SOUTHEAST BEHIND THE SEA BREEZE. A LIGHTER PRESSURE GRADIENT WILL KEEP WIND SPEEDS LIGHT ALL AROUND OUTSIDE OF CONVECTION. SCATTERED SHOWERS AND STORMS HAVE DEVELOPED EARLY THIS AFTERNOON ALONG THE EAST COAST SEA BREEZE IN NORTH BREVARD/VOLUSIA COUNTIES. SLOW MOVEMENT TO THE WEST IS EXPECTED OF THESE CELLS AND THEY WILL EVENTUALLY MOVE OFF THE EAST COAST INTO THE INTRACOASTAL/NEAR SHORE WATERS OF THE WESTERN ATLANTIC. A FEW STRONGER CELLS ANCHORED ALONG THE SEA BREEZE WILL MOVE SOUTHWARD. FURTHER DEVELOPMENT OF CONVECTION WILL BE LIKELY AS THE WEST COAST SEA BREEZE (MOVING VERY SLOWLY EASTWARD AT PRESENT) MOVES INTO CENTRAL FLORIDA LATER TODAY AS WELL AS FROM SUBSEQUENT MESOSCALE BOUNDARY/LAKE BREEZE INTERACTIONS. THIS ACTIVITY WILL LAST INTO THE EVENING AND EVENTUALLY BECOME MORE ISOLATED MID TO LATE EVENING. MAIN THREATS IN PLAY REMAIN FREQUENT CLOUD TO GROUND LIGHTNING...GUSTY DOWNBURST WINDS IN EXCESS OF 50 MPH...COIN SIZE HAIL AND TORRENTIAL DOWNPOURS CAUSING PONDING OF WATER...ESPECIALLY IN PRONE LOCATIONS DUE TO THE SLOW NATURE OF THESE STORMS. DEEPER MOISTURE (1.61 PWAT FROM 15Z KXMR SOUNDING)...MID-LEVEL IMPULSES AND COOLER AIR ALOFT ALL PLAYING A PART IN THE CONVECTIVE ACTIVITY. ...PREVIOUS EXTENDED DISCUSSION... TUE-THU...BROAD TROUGHING ALOFT WILL PERSIST INTO LATE WEEK...WHICH WILL KEEP LOW LEVEL RIDGE AXIS SUPPRESSED SOUTH OF CENTRAL FLORIDA. WHILE SUFFICIENT MOISTURE WILL EXIST FOR AT LEAST SCT AFTN/EVENING CONVECTION...SUBTLE H50 VORT LOBES PASSING OVHD SHOULD LEAD TO A LTL HIGHER POPS (50-60) ON THAT DAY AREAWIDE. FLOW FLATTENS SLIGHTLY WED-THU...WITH HIGHER POPS INDICATED ALONG THE EAST COAST (50 VS 40) IN PROXIMITY TO LATE DAY SEA BREEZE. BY THU...DEEPEST MOISTURE IS PROGGED TO GET PUSHED A BIT FARTHER SOUTH TOWARD LAKE OKEECHOBEE... AHEAD OF WEAK COOL FRONT THAT SAGS INTO CENTRAL FLORIDA THU NIGHT. POPS OVER THE SOUTHERN CWA WILL BE ABOUT 10 PCT HIGHER (40 VS 30). MAV TEMPS LOOK LIKE THEY RUN ABOUT A DEGREE OR TWO ABOVE CLIMO... WHICH LOOKS FINE GIVEN THE SW FLOW REGIME. EARLY MAY MID LEVEL ATMOSPHERIC TEMPS TYPICALLY FAVOR SOME STRONG TO MARGINALLY SEVERE STORMS. FRI-MON...FRONTAL BOUNDARY WASHES OUT OVER SOUTH FL/STRAITS BY LATE FRI AS ONSHORE FLOW TAKES HOLD AND FRESHENS SOME INTO THE WEEKEND. EVEN WITH IMMEDIATE RETURN TO ONSHORE FLOW...MEAN DRYING INDICATED FOR FRI-SAT DUE TO TRANSIENT MID LEVEL RIDGE WHICH BUILDS ALOFT. POPS BOTH DAYS 20 OR LESS....TEMPTED TO GO WITH JUST LOW TOPPED SHOWERS (CONFINED TO THE SOUTH FRI) BUT SINCE WERE GETTING TOWARD LATE MAY KEPT TS IN FCST. INCREASING MOISTURE/POPS INDICATED FOR SUN-MON AS NEXT SHORT WAVE TROUGH MOVES TOWARD THE SERN CONUS. && .AVIATION...PREVAILING VFR OUTSIDE OF CONVECTION. EAST COAST SEA BREEZE HAS FORMED AS OF VERY EARLY THIS AFTERNOON BECOMING NOTICEABLE FIRST ACROSS THE VOLUSIA/NORTH BREVARD COASTS. WINDS HAVE BECOME E/ENE BEHIND IT HERE. FURTHER SOUTH WEAK OFFSHORE WINDS WILL BECOME E/ESE AS THE SEA BREEZE DEVELOPS AND MOVES ONSHORE. SCT SHRA/TSRA WILL RESULT FROM DEEPER MOISTURE...PVA ALOFT AND BOUNDARY COLLISIONS INTO THE EVENING. RISKS TO AVIATION INCLUDE FREQUENT LIGHTNING...COIN SIZE HAIL...HEAVY DOWNPOURS AND GUSTY DOWNBURST WINDS IN EXCESS OF 40 KTS. ACTIVITY WILL EVENTUALLY BECOME ISOLATED THIS EVENING/OVERNIGHT. LCL LOW (STRATUS) CLOUDS/PATCHY GROUND FOG CANNOT BE RULED OUT TOWARDS SUNRISE TUE MORNING. ABOVE NORMAL CONVECTION CHANCES WILL CONTINUE AGAIN ON TUE WITH SIMILAR THREATS. && .MARINE...AFTN MON-TUE...SURFACE BOUNDARY LINGERING OVER THE AREA WILL BE RESPONSIBLE FOR SCATTERED LIGHTNING STORMS ACROSS INLAND LAKES...INTRACOASTAL WATERWAYS AND NEAR SHORE/OFFSHORE MARINE ZONES. CONDITIONS FAVORABLE FOR A FEW STRONG/ISOLD SVR CELLS WITH WINDS IN EXCESS OF 35 KTS...COIN SIZE HAIL...CLOUD TO WATER LIGHTNING AND TORRENTIAL DOWNPOURS. CELLS WILL MOVE OFF THE COAST AT LESS THAN 10 KTS WITH MOST FAVORABLE LOCATION FROM THE CAPE NORTHWARD. WITH SUCH A WEAK PRESSURE GRADIENT...WINDS WILL BE LIGHT/VARIABLE AT TIMES...THOUGH ARE FORECAST TO BE EAST/NORTHEAST CAPE NORTHWARD AND EAST/SOUTHEAST SOUTHWARD. THIS EVENING WINDS ARE FORECAST TO BECOME SE/S AND EVENTUALLY SW LATE OVERNIGHT TOWARDS DAYBREAK. ON TUE...INITIAL SW WINDS LESS THAN 10 KTS WILL BACK TO S/SE NEAR THE COAST DUE TO EAST COAST SEA BREEZE FORMATION AND BEGIN TO STRENGTHEN SLIGHTLY. SEAS DUE TO AN INCOMING SWELL FORECAST TO BUILD TO 3-4 FT NEAR SHORE/3-5 FT OFFSHORE THRU THE PERIOD. ANOTHER ROUND OF OFFSHORE MOVING SHOWERS/STORMS FORECAST ON TUE WITH SIMILAR THREATS AS THE PAST DAY. WED-FRI...NOT A WHOLE LOW OF WIND CHOP INDICATED GIVEN THE PROXIMITY OF THE LOW LEVEL RIDGE AXIS TO THE SOUTH. WAVE MODEL GUIDANCE DOES SHOW SOME SWELL COMPONENT KEEPING SEAS A FOOT OR TWO HIGHER THAN THEY NORMAL WOULD BE WITH THIS KIND OF WIND REGIME. OFFSHORE FLOW WILL PREVAIL THROUGH THU WITH AN ONSHORE AFTERNOON SEA BREEZE NEAR THE IMMEDIATE COAST...MAINLY SOUTH. GIVEN THE PREVAILING WESTERLY STEERING FLOW...THE MAIN MARINE CONCERN FOR THE UPCOMING WEEK WILL BE OFFSHORE MOVING THUNDERSTORMS. DEVELOPING ONSHORE FLOW STARTING THU NIGHT WILL LEAD TO A SLIGHT SURGE IN ENE-EAST WINDS AND SEAS. && .FIRE WEATHER...REMAINDER OF TODAY-TONIGHT...A WEAK FRONTAL TROUGH HAS SETTLED IN OVER THE AREA (NORTH) AND WILL PROVIDE A FOCUS FOR SHOWERS/STORMS. SEA BREEZES/MESOSCALE BOUNDARY INTERACTIONS THROUGH THIS EVENING WILL ALSO HELP INITIATE NEW CELL GROWTH. A FEW LIGHTNING STORMS MAY SPARK ADDITIONAL WILDFIRES AND WILL ALSO BE CAPABLE OF GUSTY DOWNBURST WINDS TO AROUND 50 MPH. CELL MOVEMENT SHOULD BE OUT OF THE WEST AT LESS THAN 10 MPH. OCCASIONALLY CELLS WILL ZIPPER SOUTHWARD ALONG THE EAST COAST SEA BREEZE. WITH THE WEAK OVERALL PRESSURE GRADIENT THE DISPERSION CONDITIONS WILL REMAIN RATHER POOR. LVORI'S WILL BE RATHER HIGH WITH THE LIGHT WINDS AND MOISTURE NEAR THE SURFACE. TUE...CONTINUED DEEPER MOISTURE AND BOUNDARY COLLISIONS WILL AGAIN CREATE SCATTERED SHOWERS/STORMS ACROSS THE AREA...ESPECIALLY DURING THE AFTERNOON/EARLY EVENING. AGAIN...LIGHTNING IGNITIONS/GUSTY STORM OUTFLOWS WILL BE MAIN FIRE WEATHER CONCERN. WED ONWARD...NO RH/WIND ISSUES...HOWEVER LTG IGNITIONS WILL BE MAIN FIRE WX CONCERN. && .PRELIMINARY POINT TEMPS/POPS...

LUCIE-MARTIN-COASTAL VOLUSIA- SOUTHERN LAKE-NORTHERN BREVARD- 1115 AM EDT MON MAY 7 2012 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT. .THUNDERSTORM IMPACT... A WEAK FRONTAL BOUNDARY IS DRAPED ACROSS NORTH CENTRAL FLORIDA AND WILL BECOME STATIONARY THIS AFTERNOON. MOISTURE POOLING ALONG THE FRONT WILL COMBINE WITH SEA AND LAKE BREEZE BOUNDARIES TO ACT AS FOCI FOR AFTERNOON LIGHTNING STORMS. THE HIGHEST RAIN CHANCES EXIST ALONG AND NORTH OF THE I 4 CORRIDOR BUT MAY EXTEND SOUTHWARD INTO OSCEOLA COUNTY LATE THIS AFTERNOON OR EARLY THIS EVENING WITH A SEA BREEZE COLLISION. STORM MOTION WILL BE GENERALLY TOWARD THE EAST BUT MAY BE SLOW AND ERRATIC ALONG BOUNDARIES. THE PRIMARY THREAT FROM THESE STORMS WILL BE FREQUENT CLOUD-TO-GROUND LIGHTNING... STRONG DOWNBURST WINDS AND HAIL. ONE OR TWO STORMS MAY BECOME SEVERE CONTAINING DAMAGING WINDS NEAR 60 MPH AND LARGE HAIL. .MARINE THUNDERSTORM GUST IMPACT... SCATTERED THUNDERSTORMS ARE EXPECTED AREA WIDE THIS AFTERNOON AND PUSH EAST-NORTHEAST AROUND 10 MPH THROUGH THE EARLY EVENING. THE STORMS WILL BE CAPABLE OF PRODUCING FREQUENT LIGHTNING AND STRONG WIND GUSTS UP TO 50 KNOTS AS THEY PUSH OFFSHORE INCLUDING THE INLAND LAKES. .RIP CURRENT IMPACT... WEATHER AND OCEAN CONDITIONS WILL PRODUCE AN ELEVATED THREAT FOR RIP CURRENTS AT THE BEACHES OF EAST CENTRAL FLORIDA TODAY. CHECK WITH LIFEGUARDS ABOUT OCEAN HAZARDS WHEN ARRIVING AT THE BEACH. SWIM ONLY WHERE THERE IS A LIFEGUARD ON DUTY. .FIRE WEATHER IMPACT... THERE IS A HIGH ENVIRONMENTAL FIRE DANGER OVER MOST OF THE REGION TODAY. THE THREAT WILL BE FURTHER ELEVATED TODAY AS SCATTERED LIGHTNING STORMS ARE EXPECTED. BRUSH FIRES CAN START EASILY FROM MOST CAUSES. UNATTENDED FIRES ARE LIKELY TO ESCAPE IN DRY FUELS. FIRES MAY START RAPIDLY AND SHORT DISTANCE SPREADING OF EMBERS WILL BE POSSIBLE. OUTDOOR BURNING MAY BE PROHIBITED IN YOUR AREA. .DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY. SCATTERED TO NUMEROUS LIGHTNING STORMS ARE FORECAST THROUGH MIDWEEK. THESE STORMS WILL AFFECT BOATERS AS THEY CROSS THE INTRACOASTAL WATERS AND ATLANTIC DURING THE AFTERNOON AND EVENING. A FEW STORMS MAY CONTAIN STRONG DOWNBURST WINDS...SMALL HAIL...AND FREQUENT LIGHTNING STRIKES. .SPOTTER INFORMATION STATEMENT... SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE IF NEEDED. KELLY/BRAGAW
