The episode as NWS ILM wrote it up.
Thunderstorms developed along the Piedmont trough during the early afternoon. These storms blossomed given the high instability and deep moisture. A few of these storms pulsed to severe levels as they interacted with the approaching seabreeze.

NWS Wilmington, NC wrote its last area forecast discussion before the first event at Jun 28, 1:55 PM EST, 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON NC 255 PM EDT TUE JUN 28 2011 .SYNOPSIS... A COLD FRONT WILL APPROACH FROM THE NORTHWEST AND MOVE ACROSS THE AREA ON WEDNESDAY. THE GREATEST POTENTIAL FOR SHOWERS AND THUNDERSTORMS WILL BE THIS AFTERNOON INTO WEDNESDAY AFTERNOON. SOME THUNDERSTORMS THIS AFTERNOON AND EVENING MAY BE STRONG TO SEVERE. FLOODING WILL BE POSSIBLE IN THOSE AREAS WHERE THUNDERSTORMS REPEATEDLY MOVE ACROSS THE SAME AREA. WEAK HIGH PRESSURE WILL FOLLOW FROM THE NORTH THURSDAY THROUGH FRIDAY. BERMUDA HIGH PRESSURE WILL BUILD BACK ACROSS THE AREA THROUGH THE HOLIDAY WEEKEND. && .NEAR TERM /THROUGH TONIGHT/... AS OF 130 PM TUESDAY...AFTERNOON CU HAS DEVELOPED WEST OF THE SEA BREEZE AND THE BEST ENHANCEMENT IS SEEN OVER INLAND NORTHEAST SOUTH CAROLINA. ION THE CU FIELD IS SEEN OVER SOUTH CAROLINA. CURRENT MESOANALYSIS IS SHOWING SURFACE BASED CAPES OF 4000 J/KG JUST WEST OF SEA BREEZE BOUNDARY WHILE 100 MB MIXED CAPE IS RUNNING AROUND 2000 J/KG. PRECIPTABLE WATERS CONTINUE BETWEEN 1.75 AND 2.00 INCHES. THE DCAPE VALUES ARE STILL AROUND 800-900 J/KG. WITH FREEZING LEVEL VERY HIGH...DOWNBURST IS STILL THIS EVENINGS BIGGEST SEVERE WEATHER THREAT. THE CONVECTION IS EXPECTED TO CONTINUE OVERNIGHT AS A FRONTAL BOUNDARY WILL PUSH INTO THE NORTHWEST PART OF THE AREA OVERNIGHT. SO AT THIS TIME WILL CONTINUE A CHANCE OF CONVECTION OVERNIGHT. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... AS OF 230 PM TUESDAY...A COLD FRONT WILL MOVE THROUGH THE AREA WEDNESDAY BRINGING A CHANCE OF THUNDERSTORMS TO THE AREA AGAIN. BASED ON THE POSITION OF THE FRONT...THE GREATEST POTENTIAL FOR STORMS LOOKS TO BE EAST OF INTERSTATE 95. SLIGHTLY COOLER AND DRIER AIR WILL FILTER INTO THE AREA THURSDAY AND THURSDAY NIGHT. WHILE ISOLATED THUNDERSTORMS ARE NOT OUT OF THE QUESTION ALONG THE SEA BREEZE THURSDAY...THE POTENTIAL IS LOW ENOUGH THAT IT WILL NOT BE INCLUDED IN THE FORECAST. TEMPERATURES WILL RANGE FROM UPPER 80S TO LOWER 90S WEDNESDAY AND MID 80S TO AROUND 90 THURSDAY. && .LONG TERM /FRIDAY THROUGH TUESDAY/... AS OF 1 PM TUESDAY...PERIOD WILL BEGIN WITH A COLD FRONT WELL TO THE SOUTH AND HIGH PRESSURE BUILDING INTO THE AREA FROM THE NORTH. UPPER RIDGE OVER THE SOUTHERN PLAINS BUILDS EAST THROUGH THE PERIOD WHICH FAVORS A DRY FORECAST THROUGH MUCH OF THE HOLIDAY WKND AS ENERGY IMPULSES IN THE UPPER FLOW ARE DIVERTED WELL NORTH OF THE CAROLINAS. PWATS THROUGH SATURDAY REMAIN AOB 1.5 INCHES...THEN BEGIN TO RISE TOWARDS THE JULY 4TH HOLIDAY AS BERMUDA HIGH PRESSURE SETS UP...AGAIN RETURNING THE AREA TO A TYPICAL SUMMERTIME PATTERN. THIS WILL CREATE MORE TYPICAL DIURNAL TSTM ACTIVITY ALONG THE PIEDMONT TROUGH AND SEA BREEZE FOR THE END OF THE PERIOD. HOWEVER...GUIDANCE IS PROBABLY OVERDOING PRECIP POTENTIAL AS IT MAY BE BREAKING DOWN THE UPPER RIDGE TOO QUICKLY. WILL INCREASE POP EACH DAY THROUGH THE END OF THE PERIOD BUT KEEP ONLY SLIGHT CHANCE ATTM. BY TUESDAY CONSENSUS DOES BREAK DOWN THE UPPER RIDGE SO BEST CHANCE OF PRECIP WILL BE THE VERY END OF THE EXTENDED. WITH BUILDING UPPER RIDGE AND 850 TEMPS CLIMBING INTO THE LOW 20S CELSIUS...SURFACE TEMPS WILL RISE INTO THE MIDDLE AND UPPER 90S...PEAKING ON THE 4TH WITH A FEW 100 DEGREE READINGS POSSIBLE. TEMPERATURES WILL FALL ON TUESDAY BUT REMAIN ABOVE CLIMO. MINS EACH NIGHT WILL STAY MUGGY...FROM AROUND 70 TO THE MID 70S. EARLY GLANCE AT WEATHER FOR FIREWORKS DISPLAYS ON THE NIGHTS OF THE 3RD AND 4TH SUGGESTS MOSTLY CLEAR SKY CONDITIONS AND WARM TEMPERATURES WITH ONLY AN ISOLATED SHOWER POSSIBLE. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... AS OF 18Z...MODERATE CONFIDENCE IN FORECAST DUE TO POSSIBLE AFTERNOON CONVECTION. DIURNAL CU BEGINNING TO SPREAD ACROSS THE CWA. THERE IS CURRENTLY NO ACTIVITY ON RADAR...BUT SCATTERED SHOWERS AND STORMS ARE EXPECTED TO DEVELOP THIS AFTERNOON/EVENING. GOOD SFC HEATING IS ALLOWING FOR THE ATMOSPHERE TO DESTABILIZE AND WITH PIEDMONT TROUGH IN PLACE WE SHOULD START TO SEE STORMS FIRE. CONVECTION COULD POSSIBLY PERSIST INTO THE OVERNIGHT. STORMS WILL MAINLY CAUSE STRONG AND GUSTY WINDS...WITH PERIODS OF LOWERED VSBYS WITHIN HEAVIEST RAINFALL. HAVE KEPT VCSH/VCTS FOR NOW AND WILL MONITOR EVOLUTION AND UPDATE AS NEEDED. OTHERWISE...WINDS WILL PICK UP AS PG TIGHTENS DUE TO APPROACHING FRONT. SOUTHWEST FLOW WILL BACK A BIT TO THE SOUTH AS SEA BREEZE PUSHES INLAND. CURRENT MODEL SOUNDINGS DO SHOW SATURATION AROUND DAYBREAK ASSOCIATED WITH COLD FRONT APPROACHING FROM THE WEST. THUS HAVE INCLUDED VCSH IN THE MORNING. BEHIND FRONT WINDS WILL BE FAIRLY LIGHT AND NORTHERLY. EXTENDED OUTLOOK...SHOWERS/THUNDERSTORMS POSSIBLE EACH AFTERNOON THROUGH THURSDAY. VFR EXPECTED THROUGH THE WEEKEND. && .MARINE... NEAR TERM /THROUGH TONIGHT/... AS OF 130 PM TUESDAY...WINDS HAVE INCREASED FROM THE SOUTHWEST AT 10 TO 15 KT AND WITH APPROACHING FRONTAL BOUNDARY WINDS WILL CONTINUE AT 15 TO 20 KNOTS OVERNIGHT. SEAS WILL INCREASE TO 5 FEET AT 20 MILES OUT SO WILL CONTINUE SMALL CRAFT EXERCISE CAUTION. SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... AS OF 230 PM TUESDAY...COLD FRONT WILL APPROACH THE WATERS ON WED WITH DECENT SOUTHWESTERLY FLOW UP AROUND 15 KTS. THE FLOW WILL WEAKEN AND VEER AROUND BY LATE DAY AS FRONT TRACKS ACROSS THE WATERS. SEAS ARE EXPECTED TO DIMINISH WEDNESDAY AND WEDNESDAY NIGHT IN RESPONSE TO A DIMINISHING WINDS RESULTING FROM A WEAKENING GRADIENT. WEAK HIGH PRESSURE WILL RESULT IN VARIABLE WINDS THURSDAY AND THURSDAY NIGHT AS MESOSCALE PROCESSES DOMINATE. WIND SPEEDS OF 10 KT OR LESS ARE EXPECTED WITH SEAS OF 3 FT OR LESS. LONG TERM /FRIDAY THROUGH SATURDAY/... AS OF 1 PM TUESDAY...INCREASING SELY SWELL AROUND BERMUDA HIGH WILL BUILD TO 3 FT AT 9 SEC THROUGH THE PERIOD. THIS WILL DOMINATE THE WAVE SPECTRUM BOTH FRI AND SAT AS WEAK PRESSURE GRADIENT CREATES ONLY LIGHT WINDS. GUIDANCE IS SUGGESTING ONLY A 1 FT WIND WAVE WHICH WILL CONTRIBUTE ALMOST NOTHING TO SIGNIFICANT WAVE HEIGHT OR STEEPNESS...SO SEAS WILL BE ENTIRELY SWELL DOMINATED AND AROUND 2 TO 3 FT. ON SUNDAY...WINDS WILL INCREASE AS STRENGTHENING PIEDMONT TROUGH TIGHTENS THE GRADIENT ENOUGH TO CREATE 10 TO 15 KT SWLY WINDS. THIS WILL CAUSE A MORE CONFUSED SEA WITH SW WIND WAVES OVERLYING THE CONTINUING SE SWELL...CREATING 4 FT SEAS ON SUNDAY ACROSS THE OUTER WATERS...3 FT NEAR SHORE. && .ILM WATCHES/WARNINGS/ADVISORIES...
