High pressure was the dominant feature over the forecast area. A few thunderstorms developed and became strong as they interacted with outflow boundaries and an inland moving seabreeze during peak heating hours over southeast Georgia.

The episode as NWS CHS wrote it up.
High pressure was the dominant feature over the forecast area. A few thunderstorms developed and became strong as they interacted with outflow boundaries and an inland moving seabreeze during peak heating hours over southeast Georgia.
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 Aug 20, 12:59 PM EST, 1 hour 24 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 159 PM EDT SAT AUG 20 2011 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL PREVAIL OVER THE REGION THROUGH THIS WEEKEND. A COLD FRONT WILL APPROACH FROM THE NORTHWEST MONDAY... THEN STALL AND EVENTUALLY DISSIPATE OVER OR NEAR THE AREA THROUGH THE MIDDLE OF NEXT WEEK. SURFACE HIGH PRESSURE WILL REBUILD TO THE NORTH LATE NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... SCATTERED CONVECTION HAS INITIATED THIS AFTERNOON ACROSS THE FAR WESTERN PORTION OF THE CWA...WITH MORE ISOLATED COVERAGE ALONG THE BERKELEY/WILLIAMSBURG COUNTY LINE. IN BETWEEN THESE TWO AREAS THERE IS VIRTUALLY NO CU DEVELOPING AT THIS TIME. IN FACT...THE MOST RECENT OPERATIONAL MODEL RUNS HAVE BACKED OFF OF THE CONVECTIVE COVERAGE FOR THIS AFTERNOON AND EVENING QUITE A BIT. GIVEN THE CURRENT PLACEMENT OF THE CONVECTION I THINK THE HIGHEST POP WILL BE NEEDED ACROSS THE GA ZONES WHERE I HAVE PLACED 40 POPS FOR THE AFTERNOON. THESE STORMS HAVE DISPLAYED A SLOW SOUTHEASTWARD MOVEMENT BUT I THINK THE INLAND PENETRATION OF THE SEA BREEZE WILL HELP KEEP SCATTERED STORMS CONFINED TO THIS AREA. CHANCE OF SEVERE STORMS IS PRETTY LOW BUT CERTAINLY NON ZERO. FREZZING LEVEL IS LOWER THAN YESTERDAY...ABOUT 13 KFT...BUT SOUNDING SHOWS BETTER MOISTURE THROUGH THE COLUMN SO DCAPE VALUES ARE MUCH LOWER. THEREFORE...PERHAPS JUST A COUPLE OF STRONG TO SEVERE STORMS THIS AFTERNOON AND EVENING. && .SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/... TSTMS WILL GRADUALLY WIND DOWN DURING THE EVENING HOURS AS INSTABILITY WANES AND DNVA DEVELOPS IN THE WAKE OF THE PASSING SHORTWAVE. IT WILL LIKELY TAKE A GOOD PART OF THE EVENING TO DEBRIS CLOUDINESS TO DIMINISH...BUT EXPECT MOSTLY CLEAR TO PARTLY CLOUDY SKIES TO DOMINATE BY SUNRISE SUNDAY. LOWS WILL RANGE FROM THE LOWER 70S INLAND WITH MID 70S AT THE BEACHES. LOCALLY LOWER VALUES ARE CERTAINLY POSSIBLE WHERE TSTMS OCCUR. THE RIDGE ALOFT EXTENDING ACROSS THE REGION WILL RETREAT TO THE WEST ON SUNDAY...AS AN UPPER TROUGH BUILDS INTO THE MID ATLANTIC AND SOUTHEAST STATES BY MONDAY. SHORTWAVE ENERGY TRACKING WITHIN NORTHWEST FLOW ALOFT WILL ASSIST IN THE DEVELOPMENT OF AN INLAND SURFACE TROUGH AND THE PROGRESSION OF AN ASSOCIATED COLD FRONT MONDAY NIGHT INTO TUESDAY. SUNDAY WILL BE A TRANSITION DAY WITH ATLANTIC HIGH PRESSURE REMAINING THE DOMINANT FEATURE THROUGH MUCH OF THE AFTERNOON HOURS. INITIAL CONVECTIVE ACTIVITY WILL BE DRIVEN MAINLY BY TYPICAL DIURNAL INSTABILITY AND SEA BREEZE CONVERGENCE. WILL THUS CONTINUE TO INDICATE SLIGHT TO LOW CHANCE POPS FOR SUNDAY AFTERNOON AND EARLY EVENING. HAVE THEN CONTINUED SLIGHT RAIN CHANCES THROUGH SUNDAY NIGHT CONSIDERING THAT SYNOPTIC SCALE FEATURES COULD ALLOW ISOLATED THUNDERSTORMS TO PERSIST BEYOND THE FAVORED DAYTIME HOURS. THERE IS DECENT MODEL CONSENSUS THAT THE FRONT WILL SHIFT INTO THE FORECAST AREA BY LATE MONDAY. HAVE RAISED POPS INTO THE 40 PERCENT RANGE DUE TO INCREASING CONFIDENCE IN THUNDERSTORM COVERAGE WITH THE FRONTAL PROGRESSION. STORM PREDICTION CENTER HAS PLACED NORTHERN PORTIONS OF THE FORECAST AREA WITHIN A 5 PERCENT RISK FOR SEVERE WEATHER ON MONDAY. ENHANCED FORCING PROVIDED BY BOTH THE COLD FRONT AND DECENT UPPER LEVEL DYNAMICS...IN ADDITION TO INCREASING DEEP LAYER MOISTURE WITHIN TYPICAL DAYTIME INSTABILITY...COULD ALLOW FOR ISOLATED STORMS TO BECOME STRONG OR POSSIBLY SEVERE. PREFER TO WAIT ON MENTIONING SEVERE WEATHER IN THE HAZARDOUS WEATHER OUTLOOK AT THIS TIME...AND ALLOW SUBSEQUENT FORECAST SHIFTS TO CONSIDER ADDING MENTION IF MODELS REMAIN ON TRACK. THE COLD FRONT WILL CONTINUE TO DRIFT SOUTHWARD ON TUESDAY BEFORE STALLING OVER THE FORECAST AREA. DEEPEST MOISTURE WILL SHIFT SOUTH WITH THE FRONT...AND EXPECT LESS THUNDERSTORM COVERAGE ON TUESDAY AS A RESULT. WILL KEEP RAIN CHANCES GENERALLY IN THE 20 TO 30 PERCENT RANGE FOR TUESDAY AFTERNOON AND EVENING...HIGHEST ALONG AND INLAND OF THE SEABREEZE. TEMPERATURES WILL REMAIN A FEW DEGREES ABOVE SEASONAL NORMALS SUNDAY THROUGH TUESDAY...RANGING IN THE LOWER TO MID 90S AWAY FROM THE LOCALLY COOLER COASTLINE. TUESDAY COULD BE SLIGHTLY COOLER THAN PREVIOUS DAY...AS SURFACE FLOW BECOMES NORTHEAST TO EAST BEHIND THE DESCENDING FRONT. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... THERE REMAINS A LOT OF UNCERTAINTY IN THE DETAILS OF THE EXTENDED FORECAST...AS ALL MODELS INDICATE SOME POTENTIAL INFLUENCE FROM A TROPICAL CYCLONE BY LATE IN THE WEEK. AS THESE DEVELOPMENTS ARE QUITE FAR OUT INTO THE FORECAST PERIOD...PREFER TO TAKE A CONSERVATIVE APPROACH AT THIS TIME. SURFACE HIGH PRESSURE WILL REBUILD BEHIND THE GRADUALLY DISSIPATING FRONT ACROSS THE SOUTHEAST STATES BY LATE TUESDAY...SETTLING BACK OVER THE ATLANTIC BY THE MIDDLE OF THE WEEK. WILL MAINTAIN CHANCE POPS INTO THE WEEKEND TO HINT AT THIS UNSETTLED PATTERN...WHILE KEEPING TEMPERATURES WITHIN A FEW DEGREES OF SEASONAL NORMALS. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... VISIBLE SATELLITE IMAGERY SHOWS THAT CU COVERAGE NEAR CHS AND SAV IS QUITE LOW AT THIS POINT. IN FACT...WITH CONVECTION DEVELOPING PRETTY FAR REMOVED FROM SAV AND THE SEA BREEZE BOUNDARY BEGINNING TO PUSH INLAND...I HAVE REMOVED THE TEMPO TS AND ALSO KEPT CB OUT OF THE TAF. EXPECT ONSHORE FLOW THROUGH THE EVENING...BECOMING MORE SW OVERNIGHT. SCT CU WILL DIMINISH AFTER SUNSET AND ONLY EXPECT SCT DEBRIS HIGH CLOUDS FROM MIDLANDS CONVECTION OVERNIGHT. OTHERWISE...VFR THROUGH THE TAF PERIOD. EXTENDED AVIATION OUTLOOK...SCATTERED AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS MAY BRIEFLY REDUCE VSBYS AND/OR CIGS THROUGH THE PERIOD. && .MARINE... THERE ARE NO MARINE CONCERNS THROUGH TONIGHT. SOUTH/SOUTHWEST WINDS THIS MORNING WILL GRADUALLY BACK TO THE SOUTHEAST THIS AFTERNOON AS THE SEA BREEZE DEVELOPS. BUOY OBSERVATIONS INDICATE COMBINED SEAS ARE COMPRISED OF 7-9 SECOND SWELLS. THIS WILL CONTRIBUTE TO SLIGHTLY ELEVATED SEAS OF 2-4 FT THROUGH TONIGHT...BUT WELL BELOW SMALL CRAFT ADVISORY THRESHOLDS. SUNDAY THROUGH WEDNESDAY...THE COASTAL WATERS WILL REMAIN ON THE WESTERN PERIPHERY OF ATLANTIC HIGH PRESSURE ON SUNDAY...BEFORE A COLD FRONT GRADUALLY SLIPS SOUTH INTO THE MARINE ZONES LATE MONDAY INTO TUESDAY. SOUTHWEST SURFACE FLOW SUNDAY AND MONDAY WILL BECOME EAST/NORTHEAST BEHIND THE FRONT TUESDAY AND WEDNESDAY. EXPECT WINDS AND SEAS TO REMAIN BELOW ADVISORY CRITERIA THROUGH THE PERIOD. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
