The episode as NWS CHS wrote it up.
A few thunderstorms developed during the evening hours as a short wave approached from the Southeast and interacted with an inland moving seabreeze over southeast Georgia. Thunderstorms became strong with damaging wind gusts while they developed within an atmosphere featuring DCAPE between 1000-1200 J/KG.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Jun 25, 6:23 PM EST, 34 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 723 PM EDT SAT JUN 25 2011 .SYNOPSIS... THE REGION WILL REMAIN BETWEEN ATLANTIC HIGH PRESSURE AND AN INLAND TROUGH OF LOW PRESSURE THROUGH THE MIDDLE OF NEXT WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... SHORT WAVE APPROACHING FROM THE NW THIS EVENING AND THE INLAND MOVING SEA BREEZE WILL LEAD TO ISOLATED TO SCATTERED CONVECTION...MAINLY OVER SE GA SOUTH OF I-16. THIS AREA THAT HAS THE BEST LOW LEVEL LAPSE RATES...MUCCAPES...SBCAPES AND LIFTED INDICES. THE SLOW MOVEMENT TO STORMS TO THE EAST AND SE WILL RESULT IN LOCALLY HEAVY RAINS...AS MUCH AS 1/2 TO 1 INCH IN A FEW SPOTS IN AN HOURS TIME. DCAPES ARE STILL 1000-1200 J/KG SOME WIND GUSTS TO 40 OR 50 MPH ARE CERTAINLY POSSIBLE IN A COUPLE OF STORMS WHERE BOUNDARY INTERACTION OCCURS. THIS WOULD BE MAINLY FROM EFFINGHAM TO TATTNALL COUNTY. WE WILL CARRY MAINLY 20 POPS FROM BEAUFORT TO EFFINGHAM AND TATTNALL...BUT SOME 30-40 POPS OVER LIBERTY...LONG AND MCINTOSH. THE NOCTURNAL ENVIRONMENT WILL ALLOW FOR CONVECTION TOP STEADILY DIMINISH IN BOTH COVERAGE AND INTENSITY THIS EVENING...WITH PROBABILITIES FALLING UNDER 15 PERCENT BY MIDNIGHT OR 1 AM AT THE LATEST. LOWEST TEMPS TONIGHT WILL GENERALLY FALL TO THE LOWER AND MIDDLE 70S...EXCEPT A FEW UPPER 70S RIGHT ALONG THE SHORELINE. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... IN GENERAL...LITTLE CHANGE IN THE PATTERN IS EXPECTED THROUGH THE PERIOD AS A BROAD UPPER TROF REMAINS OVER THE EASTERN 1/3 OF THE COUNTRY...AND UPPER RIDGES CENTERED TO THE WEST OVER THE SOUTH CENTRAL U.S. AND TO THE EAST OVER THE ATLANTIC WATERS. AT THE SURFACE...THIS PATTERN WILL CONTINUE TO KEEP A WEAK TROF OF LOW PRESSURE OVER THE INTERIOR OF THE CAROLINAS AND INTO GEORGIA AND A RIDGE OF HIGH PRESSURE TO THE EAST OVER THE ATLANTIC...RESULTING IN WEAK SYNOPTIC SOUTHWEST FLOW OVER THE LAND. AS HAS BEEN THE TREND FOR THE PAST SEVERAL DAYS...IT LOOKS LIKE MORE TYPICAL CHANCES FOR PRECIP THROUGH THE PERIOD. HOWEVER...TIMING FOR PRECIP IS NOT THAT STRAIGHT FORWARD. THE TRICK TO FIGURING OUT POPS AND TIMING FOR THE NEXT FEW DAYS WILL BE TRACKING ANY UPSTREAM SHORT WAVES AND ASSOCIATED MCS FEATURES THAT MOVE DOWN INTO THE REGION WITHIN THE BROAD NW UPPER FLOW. FOR SUNDAY...LOOKS LIKE THE MAIN FEATURE TO SPARK CONVECTION MAY BE WITH THE ENERGY ASSOCIATED WITH AN MCS THAT IS CURRENTLY OVER THE NORTH-CENTRAL U.S.. MODELS SHOW THAT THIS FEATURE WILL MOVE SE TOWARD THE AREA...AND MAY HELP TO SPARK CONVECTION FROM WEST TO EAST BY LATER IN THE DAY SUNDAY AND INTO SUNDAY EVENING. THERE COULD BE MORE ISOLATED TO WIDELY SCATTERED CONVECTION THAT DEVELOPS IN THE SEA BREEZE IN THE AFTERNOON...BUT THINK BETTER COVERAGE/CHANCES FOR CONVECTION WILL BE WITH OUTFLOWS FROM MCS FEATURE LATER IN THE DAY/EVENING. FOR NOW HAVE KEPT POPS IN THE LOW END CHANCE RANGE...BUT WOULD NOT BE SURPRISED IF POPS NEED TO BE INCREASED AS THE EVENT DRAWS CLOSER. TEMPS WILL CONTINUE A FEW DEGS ABOVE NORMAL...GENERALLY IN THE LOW TO MID 90S FOR HIGHS AND LOW TO MID 70S FOR LOWS. MONDAY AND TUESDAY...MUCH MORE DIFFICULT IN THIS TIME FRAME TO HAVE MUCH CONFIDENCE IN TRACKING ANY DISTURBANCES IN THE NW UPPER FLOW THAT MAY ENHANCE PRECIP CHANCES EACH DAY. HAVE CONTINUED RATHER CONSERVATIVE FORECAST OF LOW END CHANCE POPS CENTERED FOR THE AFTERNOON AND EVENING...BUT AS WAS THE CASE FOR SUNDAY...WOULD NOT BE SURPRISED IF POPS END UP BEING INCREASED WITH LATER FORECASTS. TEMPS WILL CONTINUE AT LEAST 2 TO 4 DEGS ABOVE NORMAL DURING THE PERIOD. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... LEE SIDE TROUGHING EAST OF THE APPALACHIANS WILL BE REINFORCED BY WEAK TROUGHING FROM A SFC LOW SHIFTING THROUGH THE NORTHEASTERN UNITED STATES TUESDAY NIGHT AND WEDNESDAY. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE WEDNESDAY THROUGH THURSDAY EVENING AS WEAK ONSHORE FLOW LEADS TO MID 70 DEWPTS AND STRONG SFC HEATING PRODUCES SBCAPE VALUES NEAR 3500 J/KG OVER THE FORECAST AREA. OVERALL HIGH TEMPS ARE EXPECTED TO BE IN THE LOW/MID 90S WEDNESDAY. HIGH TEMPS MAY BE A FEW DEGREES COOLER BY LATE WEEK WITH THE PASSAGE OF THE WEAK SFC TROUGH AND REMAINING MID LVL CLOUDS OVER THE SOUTHEAST. && .AVIATION /23Z SATURDAY THROUGH THURSDAY/... BOUNDARY INTERACTION NEAR KSAV WILL ALLOW FOR CB CLOUDS THROUGH 0130Z. WHILE THERE MAY BE A LITTLE GROUND FOG AND/OR LOW STRATUS LATE TONIGHT/SUNDAY MORNING...PREVAILING VFR WEATHER WILL CONTINUE THROUGH 00Z MONDAY. EXTENDED AVIATION OUTLOOK...MVFR/IFR CONDITIONS POSSIBLE WITH AFTERNOON SHOWER/THUNDERSTORM ACTIVITY EACH DAY. && .MARINE... THERE ARE NO MARINE CONCERNS FOR TONIGHT. NOCTURNAL SURGING WILL NOT BE AS STRONG AS THE PAST SEVERAL NIGHTS...WITH SOUTH AND SW WINDS EXPECTED TO REMAIN 15 KT OR LESS AND SEAS 2-4 FT. BERMUDA HIGH PRESSURE WILL CONTINUE TO DOMINATE THE PATTERN THROUGH MIDDLE OF NEXT WEEK. NO HIGHLIGHTS ARE ANTICIPATED AT THIS TIME. OVERALL...SOUTHWEST WINDS OF 15 KTS OR LESS AND SEAS OF 3 TO 4 FEET OR LESS ARE EXPECTED TO PREVAIL. WINDS WILL LIKELY SURGE UP DURING THE EVENING AND EARLY MORNING HOURS EACH DAY...BUT STILL EXPECTED TO REMAIN BELOW SCA. A SLIGHTLY STRONGER INLAND TROUGH OF LOW PRESSURE MAY DEVELOP LATER IN THE PERIOD BY WEDNESDAY AND THURSDAY...WHICH MAY HELP WINDS INCREASE INTO THE 15 TO 20 KT RANGE...ESPECIALLY DURING THE NIGHTTIME HOURS. ISOLATED TO SCATTERED MAINLY EVENING THROUGH EARLY MORNING SHOWERS AND THUNDERSTORMS ARE EXPECTED THROUGH THE PERIOD. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && 33
