The episode as NWS CHS wrote it up.
A stationary front was present over southeast South Carolina. This in combination with a very moist and unstable air mass favored the development of showers and thunderstorms during peak heating hours in the afternoon. A few thunderstorms became strong as weak perturbations in the mid levels passed over the forecast area.
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 12, 11:35 AM EST, 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 1235 PM EDT FRI AUG 12 2011 ...LOCALLY HEAVY RAINS AND A RISK FOR FLOODING TODAY... .SYNOPSIS... A WEAK TROUGH OF LOW PRESSURE WILL REMAIN OVER THE SOUTHEAST STATES INTO THE UPCOMING WEEKEND. A COLD FRONT WILL APPROACH THE AREA FROM THE WEST SUNDAY AND MOVE THROUGH THE REGION SUNDAY NIGHT. HIGH PRESSURE WILL THEN REBUILD OVER THE AREA THROUGH MUCH OF NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... CONVECTION IS EVOLVING AS EXPECTED WITH A CLUSTER OF TSTMS STEADILY EXPANDING ACROSS THE CHARLESTON TRI-COUNTY AREA AND COLLETON COUNTY. SATELLITE SHOWS WHAT APPEARS TO BE AN OUTFLOW BOUNDARY LURKING FROM NEAR WALTERBORO THROUGH ALLENDALE COUNTY. CONVECTION MAY BACK BUILD ALONG THIS SOON. HAVE ADJUSTED POPS UP IN THIS AREA FOR THE NEXT FEW HOURS. DEWPOINTS ARE HOLDING IN THE UPPER 70S/LOWER 80S ALONG THE SOUTHERN SOUTH CAROLINA COAST WHICH IS HELPING TO PUSH HEAT INDICES NEAR 105 IN SOME AREAS. DO NOT ANTICIPATE THIS TO LAST TOO LONG AS CONVECTION EXPANDS...BUT MUCH OF BEAUFORT COUNTY AND COASTAL JASPER COUNTIES COULD SEE 2-3 HOURS OF 105-106 PRIOR TO CONVECTION. WILL HOLD OFF ON THE ISSUANCE OF A HEAT ADVISORY FOR THIS AREA. && .SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/... CONVERGENCE SHOULD WANE DURING THE EVENING WITH CONVECTION LIKELY TO ROLL THROUGH MUCH OF THE FORECAST AREA IN GEORGIA PRIOR TO SUNSET. A LATE NIGHT SHORT WAVE LOOKS FAIRLY FORMIDABLE AND WILL LIKELY REDEVELOP SOME CONVECTIVE RAINS IN SE SOUTH CAROLINA AFTER MIDNIGHT AND WE HAVE KEPT SOME CHANCE POPS GOING ALL NIGHT IN THE CHARLESTON TRI-COUNTY AREA. INLAND SE GEORGIA SHOULD BE DRY AFTER MID EVENING WITH SOME ISOLATED CONVECTION ALONG COASTAL GEORGIA WITH THE LAND BREEZE CONVERGENCE AND THE TAIL OF THE MID LEVEL SHORT WAVE MOVING IN. THE MAIN THREAT WILL BE SOME HEAVY DOWNPOURS POSSIBLE OVERNIGHT ALONG THE COAST. SATURDAY...LATEST MODEL SOLUTIONS SHOW A WEAK SURFACE BOUNDARY LINGERING OVER NORTHERN ZONES SERVING AS A FOCUS FOR LOW LEVEL CONVERGENCE/ISENTROPIC ASCENT AND DEEP MOIST CONVECTION THROUGH THE MORNING HOURS...SO HAVE CARRIED SLIGHT CHANCE/LOW CHANCE POPS SATURDAY MORNING HERE. BY AFTERNOON...THE BOUNDARY SHOULD WEAKEN OR DISSIPATE DUE TO DAYTIME HEATING AND THE SEA BREEZE PUSH. HIGHEST RAIN PROBABILITIES THEN APPEAR TO FOCUS INLAND AWAY FROM THE IMMEDIATE COAST AND PARTICULARLY ACROSS SOUTHEAST GEORGIA WHERE BEST SURFACE HEATING IS ANTICIPATED. WILL CARRY SLIGHT CHANCE/LOW CHANCE POPS THROUGH THE AFTERNOON HOURS...WITH HIGHEST PROBABILITIES IN LOCATIONS MENTIONED ABOVE. HIGHS ARE EXPECTED TO TOP OUT AROUND 90 TO THE LOWER 90S NORTH AND IN THE LOWER TO MIDDLE 90S SOUTH. SATURDAY NIGHT...ANY LINGERING SHOWER/THUNDERSTORM ACTIVITY SHOULD DIMINISH BY MIDNIGHT. RAIN FREE CONDITIONS THEN ANTICIPATED THROUGH DAYBREAK SUNDAY AS THE DEEPEST MOISTURE AND STRONGEST FORCING FOR ASCENT IN ASSOCIATION WITH THE APPROACHING COLD FRONT REMAIN WELL WEST OF THE AREA. LOW TEMPERATURES SHOULD BOTTOM OUT IN THE LOW TO MID 70S. SUNDAY AND SUNDAY NIGHT...MODEL SOLUTIONS REMAIN IN GOOD AGREEMENT SHOWING A COLD FRONT APPROACHING FROM THE WEST DURING THE DAY THEN MOVING THROUGH THE REGION PRIOR TO DAYBREAK MONDAY. THE COMBINATION OF DEEP MOISTURE...IMPRESSIVE DYNAMIC FORCING FOR THIS TIME OF YEAR...AND THE AFTERNOON SEA BREEZE SHOULD RESULT IN FAIRLY GOOD COVERAGE OF SHOWERS/THUNDERSTORMS ACROSS THE AREA. THEREFORE...WILL CONTINUE WITH THE HIGH CHANCE POPS AREA WIDE. WILL CONTINUE TO MENTION THE POTENTIAL FOR SEVERE WEATHER IN THE HAZARDOUS WEATHER OUTLOOK AS WELL...WITH AN UNSEASONABLY STRONG COLD FRONT AND DEEP UPPER LEVEL TROUGH MOVING THROUGH THE REGION AND INTO A MODERATELY UNSTABLE AIRMASS. THE MAIN HAZARDS APPEAR TO BE DAMAGING STRAIGHT LINE WINDS AND MARGINALLY SEVERE HAIL. HIGH TEMPERATURES ARE EXPECTED TO TOP OUT IN THE LOW TO MID 90S. EXPECT SHOWERS AND THUNDERSTORMS TO GRADUALLY DIMINISH FROM WEST TO EAST SUNDAY NIGHT...BUT WILL CARRY RAIN CHANCES ALL AREAS THROUGH THE NIGHT TO ACCOUNT FOR TIMING DIFFERENCES. LOW TEMPERATURES SHOULD BOTTOM OUT IN THE LOW TO MID 70S. MONDAY...GUIDANCE AGREES THAT THE DEEPEST MOISTURE AND STRONGEST FORCING FOR ASCENT WILL HAVE SHIFTED OFFSHORE PRIOR TO DAYBREAK...SO WILL KEEP THE FORECAST RAIN FREE. EXPECT TEMPERATURES TO TOP OUT IN THE LOW TO MID 90S...BUT WITH LOWER HUMIDITY VALUES IT WILL LIKELY FEEL COOLER THAN IT HAS OVER THE PAST SEVERAL WEEKS. && .LONG TERM /MONDAY NIGHT THROUGH THURSDAY/... MODEL SOLUTIONS ARE IN GOOD AGREEMENT SHOWING HIGH PRESSURE AND A DRIER AIRMASS BUILDING OVER THE SOUTHEAST STATES THROUGH MUCH OF NEXT WEEK. AS A RESULT...WE CONTINUE TO EXPECT A DRY PERIOD OVER SOUTHERN SOUTH CAROLINA AND SOUTHEAST GEORGIA...AND WILL KEEP THE FORECAST RAIN FREE AT THIS TIME. TEMPERATURES ARE EXPECTED TO RUN NEAR TO SLIGHTLY ABOVE NORMAL...ALTHOUGH LOWER HUMIDITY LEVELS WILL MAKE IT FEEL QUITE A BIT MORE COMFORTABLE THAN THE PAST SEVERAL WEEKS. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... KCHS...SHOWER AND TSTM CHANCES WILL INCREASE LATER THIS MORNING AND ESPECIALLY THIS AFTERNOON AS THE SEA BREEZE GETS GOING AND ATLC MOISTURE CONVERGES ALONG BOUNDARIES. WE CONTINUE TO TREND WITH SCATTERED CB. RADAR TRENDS WILL EVENTUALLY DICTATE ANY INCLUSIONS OF TSRA AND TIMING TRENDS AS THE DAY WEARS ON. MODELS SUGGEST ATLC MOISTURE CONVERGENCE AND AN UPPER SHORT WAVE WILL ENHANCE RAINS SOMEWHERE ALONG THE CENTRAL OR UPPER SOUTH CAROLINA COAST AFTER MIDNIGHT TONIGHT. LOWER CIGS AND VSBYS POSSIBLE IF THIS BAND SETS UP THROUGH THE CHARLESTON TRI-COUNTY. KSAV...QUIET CONDITIONS/VFR WEATHER SHOULD PERSIST UNTIL AFTERNOON CONVECTION BECOMES SCATTERED TO THE N AND POTENTIALLY WORKS S OVER THE REGION THIS AFTERNOON. WE CONTINUE TO TREND BY MAINTAINING CB INTO THE TAF. TONIGHT...GENERALLY VFR CONDITIONS SHOULD PREVAIL BUT THERE IS A CHANCE FOR PATCHY MVFR VSBYS TOWARD 12Z/13. EXTENDED AVIATION OUTLOOK...SCATTERED SHOWERS AND THUNDERSTORMS MAY BRIEFLY REDUCE VSBYS AND/OR CIGS SATURDAY THROUGH SUNDAY...PRIMARILY DURING THE AFTERNOON/EVENING HOURS. OTHERWISE VFR CONDITIONS SHOULD PREVAIL. && .MARINE... COOLER DRIER AIR OVER THE MID ATLC REGION IS FORECAST TO INCITE A WEAK WEDGE LIKE PATTERN OVER THE WATERS TODAY AND TONIGHT WITH ONSHORE FLOW DEVELOPING. SPEEDS NOT EXPECTED TO TOP 15 KT BUT WE SHOULD SEE A SUBTLE INCREASE IN SEAS FROM 1 FT AT DAYBREAK TO CLOSER TO 2 FT BY LATE TODAY AND A SOLID 2 FT TONIGHT... PERHAPS 2 TO 3 FT WELL OFF THE COAST. SATURDAY THROUGH WEDNESDAY...A WEAK TROUGH OF LOW PRESSURE WILL REMAIN OVER THE SOUTHEAST STATES ON SATURDAY. A COLD FRONT WILL APPROACH THE AREA FROM THE WEST ON SUNDAY AND MOVE THROUGH THE WATERS SUNDAY NIGHT. HIGH PRESSURE WILL THEN REBUILD OVER THE AREA EARLY NEXT WEEK. OVERALL THE STRONGEST WINDS IN THE COASTAL WATERS WILL BE AT NIGHT WITH NOCTURNAL SURGING AND ALONG THE COAST DURING THE AFTERNOON/EVENING WITH THE SEABREEZE. WE DO EXPECT AN ENHANCED SURGE SUNDAY AFTERNOON THROUGH SUNDAY NIGHT ASSOCIATED WITH THE COLD FRONTAL PASSAGE. WIND SPEEDS COULD APPROACH SMALL CRAFT ADVISORY LEVELS FOR PORTIONS OF THE WATERS DURING THIS PERIOD...BUT FOR NOW WE HAVE KEPT WINDS JUST BELOW. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
