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.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Jul 6, 12:43 PM EST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 143 PM EDT WED JUL 6 2011 .SYNOPSIS... ATLC HIGH PRES WILL GENERALLY PREVAIL ACROSS THE AREA THIS WEEK. A WEAKENING COLD FRONT COULD ADVANCE INTO THE REGION N OF THE SAVANNAH RIVER THIS WEEKEND AND WILL STALL BY EARLY NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... 130 PM UPDATE...NO BIG CHANGES. INCREASED POPS A BIT INLAND BASED ON THE LATEST RADAR IMAGERY. ISOLATED SEVERE WEATHER IS POSSIBLE BUT DUE TO LACK OF SIGNIFICANT ORGANIZATION TO THE CONVECTION WILL HOLD OFF MENTIONING IN THE HAZARDOUS WEATHER OUTLOOK. PREVIOUS DISCUSSION... TODAY/S MAIN FORECAST FEATURE WILL CONTINUE TO BE THE ATLC RIDGE OVER MUCH OF THE AREA...ALTHOUGH IT IS SLOWLY GIVING WAY TO AN APPROACHING UPSTREAM MID LAYER TROUGH NUDGING DOWN FROM THE TENNESSEE VALLEY REGION. THIS TROUGH IS EXPECTED TO ENHANCE DIURNAL CONVECTION TODAY OVER A LARGE PART OF THE CAROLINA MIDLANDS AND SANDHILLS. WITH THE WEAKENING OF THE RIDGE OVER CENTRAL GEORGIA AND CSRA... WE EXPECT AN INCREASE IN COVERAGE IN AFTERNOON AND EVENING TSTMS ALONG AND W OF I-95 AND WE HAVE RAISED POPS TO 40 PERCENT IN LOCATIONS CLOSE TO THIS PROXIMITY. MUCH OF OUR CONVECTION WILL BE DRIVEN ON THE MESOSCALE WITH BOUNDARIES AND THE SEA BREEZE THE MAIN LOW LEVEL MECHANISMS. IN THE UPPER LEVELS...IT IS INTERESTING TO NOTE THAT A BROAD LEFT FRONT EXIT REGION OF THE 250 MB JET COMES UP LATE DAY FROM THE GULF OF MEXICO CUT-OFF LOW PRES SYSTEM IN THE MID/LEVELS. THIS ADDITIONAL FORCING ALONG WITH A DECENT LOW LEVEL INFLOW REGIME COULD ALLOW FOR SOME SIGNIFICANT MULTICELL CLUSTERS LATER TODAY AND THIS EVENING. MOST OF THE HIGH RESOLUTION GUIDANCE SUGGESTS THE TARGET REGION WILL BE FROM E OF AUGUSTA TO ORANGEBURG TO THE PEE DEE OF SOUTH CAROLINA. HEAVY RAINFALL LOCALLY AND ISOLATED SEVERE POTENTIAL IN THE FORM OF WET MICROBURSTS ARE POSSIBLE FOR OUR INLAND AREAS THIS AFTERNOON AND EVENING. SPC/S SLIGHT RISK DAY 1 REGION LOOKS REASONABLE AND WE WILL ALLOW FOR SOME 12Z SOUNDING ANALYSIS BEFORE COMMITTING ORGANIZED SEVERE MENTIONS IN OUR HAZARDOUS WEATHER OUTLOOK DUE TO UPSTREAM CONVECTIVE UNCERTAINTIES. LITTLE TO NO CHANGE MADE TO HIGH TEMPERATURES TODAY...LOWER TO MID 90S MOST AREAS INLAND FROM THE BEACHES AND BARRIER ISLANDS. WE DID LOWER READINGS A DEGREE OR SO TO THE E OF U.S. 17 IN SOME SPOTS. EVENING INTO OVERNIGHT STORMS MAY PERSIST IN SOUTH CAROLINA AND SOME LINGERING CONVECTION MAY FLIRT WITH THE CHARLESTON TRI-COUNTY REGION ONCE AGAIN...CONFIDENCE CERTAINLY LOW AT THIS POINT. SMOKE FROM THE WILDFIRES MAY AFFECT SOME OF THE AREA THROUGH TONIGHT AND WE CONTINUED TO MENTION SOME MORNING AREAS OF SMOKE...MAINLY OVER SE GEORGIA. && .SHORT TERM /THURSDAY 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 THE 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. GIVEN THE LACK OF MODEL AGREEMENT AND UNCERTAINTY...MADE ONLY MINOR CHANGES TO THE POPS. THE BIGGEST CHANCE WAS TO INCREASE POPS WELL INTO THE CHANCE RANGE FOR THURSDAY AND FRIDAY. 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 TUESDAY/... 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 /18Z WEDNESDAY THROUGH SUNDAY/... 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... A TYPICAL SUMMER-TIME REGIME ONGOING OVER THE WATERS...S WINDS FOR THE MOST PART...SOME SE COMPONENT OVER GEORGIA WATERS. SPEEDS OCCASIONALLY CLOSER TO 15-20 KT DURING NOCTURNAL PEAKS AND 10 KT OR LESS SEAWARD FROM THE SEA BREEZE OSCILLATION DURING THE AFTERNOON HOURS. SEAS 2 TO 4 FT. HAVE ADDED MENTION OF SMOKE FOR TODAY BASED ON THE LATEST SATELLITE IMAGERY. A MARINE WEATHER STATEMENT IS ALSO OUT ADDRESSING THE SMOKE. NO HIGHLIGHTS EXPECTED THROUGH AT LEAST FRIDAY. MODELS CONTINUE TO LACK AGREEMENT ON THE POTENTIAL EVOLUTION OF THE TROPICAL WAVE CURRENTLY OVER THE BAHAMAS. HAVE STAYED WITH THE MORE CONSERVATIVE SOLUTION...KEEPING A WEAK WAVE WELL SOUTH OVER SOUTH FLORIDA AND THE GULF OF MEXICO FRIDAY AND SATURDAY. OTHERWISE...A BROAD UPPER TROUGH WILL SET IN OVER THE AREA THROUGH SATURDAY WITH SCATTERED SHOWERS AND THUNDERSTORMS EXPECTED. WINDS GENERALLY 15 KT OR LESS AND SEAS 4 FT OR LESS THROUGH LATE FRIDAY. BY SATURDAY...EXPECT WINDS TO INCREASE TO 15-20 KT AS A SURFACE FRONT APPROACHES FROM THE NORTHWEST. WINDS SHOULD DECREASE AGAIN BY SUNDAY AND MONDAY AS HIGH PRESSURE BUILDS BACK OVER THE REGION. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
