Scattered pulse type convection developed within a weak shear and moderate CAPE environment over portions of southern South Carolina and Southeast Georgia during the afternoon and evening hours. Thunderstorms that intersected an outflow boundary as well as the inland moving sea breeze became strong, primarily producing damaging wind gusts.

The episode as NWS CHS wrote it up.
Scattered pulse type convection developed within a weak shear and moderate CAPE environment over portions of southern South Carolina and Southeast Georgia during the afternoon and evening hours. Thunderstorms that intersected an outflow boundary as well as the inland moving sea breeze became strong, primarily producing damaging wind gusts. Storms first became severe over South Carolina before developing southward in Georgia where the outflow boundary and sea breeze intersected.
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 Charleston, SC wrote its last area forecast discussion before the first event at Jul 6, 2:46 PM EST, 1 hour 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 346 PM EDT WED JUL 6 2011 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL GENERALLY PREVAIL ACROSS THE AREA THIS WEEK. A WEAKENING COLD FRONT COULD ADVANCE INTO THE REGION NORTH OF THE SAVANNAH RIVER THIS WEEKEND...STALLING BY EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... LATE AFTERNOON CONVECTION TO DIMINISH INTO THIS EVENING...ALTHOUGH SIMILAR TO LAST NIGHT THERE COULD BE ENOUGH LINGERING INSTABILITY AND MESOSCALE BOUNDARIES AS WELL AS LIFT AHEAD OF AN UPPER TROUGH TO THE WEST TO KEEP SOME SHOWERS AND THUNDERSTORMS AROUND MUCH OF THE NIGHT. ISOLATED SEVERE STORMS POSSIBLE THROUGH THIS EVENING WITH DAMAGING WINDS THE MAIN HAZARD. MILD NIGHT WITH LOWS IN THE LOWER TO MID 70S AWAY FROM THE MILDER COASTLINE. KEPT MENTION OF SMOKE IN THE FORECAST BASED ON SURFACE OBS AND SATELLITE SHOWING SMOKE STILL HANGING OVER THE AREA FROM THE WILDFIRES ACROSS SOUTHEAST GEORGIA. A SPECIAL WEATHER STATEMENT HAS ALREADY BEEN ISSUED TO ADDRESS THIS SMOKE. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... A BROAD UPPER TROUGH WILL SETTLE IN OVER THE EASTERN 1/3 OF THE COUNTRY THROUGH THE PERIOD. THE UPPER TROUGH WILL BE SHARPEST ON SATURDAY. THE ECMWF AND GFS ARE SHOWING THAT THIS UPPER TROUGH WILL BE ASSOCIATED WITH A SURFACE TROUGH/WEAK FRONT THAT COULD REACH INTO THE NORTHERN AREA BY SATURDAY. THE MODELS CONTINUE TO BE VERY DIFFERENT CONCERNING THE POTENTIAL EVOLUTION OF A WEAK TROPICAL WAVE THAT EMANATES FROM AROUND THE BAHAMAS. STILL FEEL THAT THE NAM AND CANADIAN SOLUTIONS...WHICH BRING A CLOSED LOW NORTHWARD JUST OFFSHORE OF THE AREA ON THURSDAY AND EARLY FRIDAY SEEM TOO AGGRESSIVE. CONTINUED TO FOLLOW CLOSER TO THE GFS AND ECMWF SOLUTIONS...WHICH KEEP A WEAK...OPEN TROPICAL WAVE WELL SOUTH OVER FLORIDA AND INTO THE GULF OF MEXICO BY LATER FRIDAY AND SATURDAY. THINK THE BEST CHANCES FOR RAINFALL/CONVECTION WILL BE FRIDAY AND SATURDAY AS THE UPPER TROUGH SHARPENS A BIT AND THE SURFACE FRONT/TROUGH MOVES TOWARD THE REGION. GIVEN THE PRESENCE OF AN UPPER TROUGH AND APPROACHING SURFACE FRONT...MAY SEE CONVECTION LINGER THROUGH MUCH OF THE NIGHT FRIDAY NIGHT. KEPT TEMPS NEAR NORMAL GIVEN NEAR TO SLIGHTLY ABOVE NORMAL CHANCES FOR RAINFALL. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... AN UPPER TROUGH AND ASSOCIATED SURFACE FRONT/TROUGH WILL BE MOVING ACROSS THE NORTHERN AREA ON SATURDAY. DEEP LAYER RIDGING BUILDS BACK FROM THE WEST SUNDAY THROUGH WEDNESDAY. LOOKS LIKE A WEAK SURFACE FRONT WILL STALL OVER THE NORTHERN REGION SATURDAY AND SUNDAY BEFORE WEAKENING AND MOVING NORTHWARD MONDAY AND BEYOND. THINK THE GFS IS A LITTLE TOO FAR SOUTH WITH THE SURFACE FRONT/TROUGH ON SATURDAY AND SUNDAY. DEEP LAYER MOISTURE IS PROGGED TO GRADUALLY DECREASE SATURDAY AND BEYOND AS THE UPPER RIDGE BUILDS BACK OVER THE AREA. HOWEVER...THINK THE PRESENCE OF THE WEAK SURFACE FRONT AND AFTERNOON SEA BREEZE ON SATURDAY AND SUNDAY SHOULD STILL BE ENOUGH TO PRODUCE SCATTERED AFTERNOON CONVECTION. COVERAGE OF CONVECTION EXPECTED TO BE A LITTLE LOWER BY MONDAY INTO MID NEXT WEEK AS DEEP LAYER MOISTURE BECOMES MORE MARGINAL AND THE WEAK SURFACE FRONT DISSIPATES/MOVES NORTH OF THE REGION. KEPT TEMPS NEAR NORMAL THROUGH SATURDAY THEN NEAR TO SLIGHTLY ABOVE NORMAL MONDAY AND BEYOND. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... SMOKE FROM SOUTH GEORGIA WILDFIRES WILL CONTINUE TO BE THE MAIN ISSUE THIS TAF PERIOD. CONDS ARE STARTING OUT VFR BUT MVFR CONDS ARE LIKELY TO RETURN AT SOME POINT...WITH IFR CONDS POSSIBLE...ESPECIALLY AT KSAV. SHOWERS AND TSTMS THIS AFTERNOON SHOULD MOSTLY REMAIN W OF THE TERMS...AT LEAST AFTER 21Z...SO WILL LET CB/S HANDLE THIS THREAT FOR NOW AND AMEND THE TAFS IF NEEDED BASED ON RADAR TRENDS. EXTENDED AVIATION OUTLOOK...VFR CONDITIONS EXPECTED TO DOMINATE WITH BRIEF PERIODS OF MVFR/IFR...MAINLY IN SCATTERED AFTERNOON THUNDERSTORMS. SMOKE FROM GA WILDFIRES MAY ALSO IMPACT THE TERMS...ESPECIALLY KSAV. && .MARINE... TONIGHT... S/SE WINDS TO PREVAIL MAINLY 15 KT OR LESS...MOSTLY HIGHEST ALONG THE COAST THIS EVENING WITH THE SEA BREEZE. SEAS 2 TO 4 FT. SMOKE CONTINUES ACROSS THE WATERS AND MARINERS SHOULD BE ALERT FOR VISIBILITIES OCCASIONALLY 3 NM OR LESS. A MARINE WEATHER STATEMENT HAS BEEN ISSUED TO HIGHLIGHT THE SMOKE. THURSDAY THROUGH MONDAY... ATLANTIC HIGH PRESSURE WILL REMAIN THE DOMINANT WEATHER FEATURE WITH A SOUTHERLY FLOW PERSISTING. THE ONLY POTENTIAL CAVEAT IS A WEAK LOW OVER THE BAHAMAS THAT COULD MOVE NORTH WELL EAST OF THE WATERS LATE THURSDAY THROUGH FRIDAY. ONLY THE NAM IS DOING MUCH WITH THIS FEATURE...AND BEING THAT THE NAM RARELY PERFORMS WELL WITH TROPICAL DEVELOPMENT...WE STUCK WITH A GFS/SREF SOLUTION. THE STRONGEST WINDS IN THE NEARSHORE WATERS WILL BE AT NIGHT WITH NOCTURNAL JETTING WHILE THE STRONGEST WINDS AT THE COAST WILL BE AFTERNOON/EVENING WITH THE SEABREEZE CIRCULATION. && .CHS WATCHES/WARNINGS/ADVISORIES...
