The episode as NWS CHS wrote it up.
An upper level trough approached the region from the west during the day as low level convergence boundaries set up with the onset of the afternoon sea breeze. Other boundaries from thunderstorm outflow also occurred and kept thunderstorm initiation going.

NWS Charleston, SC wrote its last area forecast discussion before the first event at Aug 9, 3:26 PM EST, 1 hour 51 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 426 PM EDT THU AUG 9 2012 .SYNOPSIS... A STRONG LOW PRESSURE SYSTEM WILL DEVELOP TO THE NORTH ON FRIDAY...WHILE AN ASSOCIATED COLD FRONT APPROACHES OVER THE WEEKEND. THE FRONT WILL LIKELY STALL OFFSHORE EARLY NEXT WEEK BEFORE A MUCH WEAKER FRONT APPROACHES BY THE MIDDLE OF NEXT WEEK. && .NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... A CLOSED LOW OVER THE WESTERN GREAT LAKES REGION WILL DROP SOUTHEAST TONIGHT...AS THE AXIS OF A MID/UPPER LEVEL TROUGH CONTINUES TO SLOWLY PROGRESS EAST OF THE MISSISSIPPI VALLEY. AT THE SURFACE...A MESO-LOW HAS FORMED OVER EAST-CENTRAL GEORGIA IN ADVANCE OF THE TROUGH...AND IS EXPECTED TO LIFT NORTHEAST TONIGHT WHILE ATLANTIC HIGH PRESSURE MAINTAINS A SYNOPTIC SOUTH-SOUTHWEST FLOW OVER THE REGION. A NOCTURNAL LOW LEVEL JET IS EXPECTED TO DEVELOP OVER THE AREA TONIGHT AHEAD OF THE UPPER TROUGH/SURFACE MESO-LOW. CONVECTION HAS BECOME SCATTERED TO NUMEROUS ACROSS MUCH OF SOUTHEAST GEORGIA THIS AFTERNOON IN CLOSER PROXIMITY TO THE DEEPER MOISTURE AS PRECIPITABLE WATER VALUES HAVE RISEN TO AROUND 2.25 INCHES IN THAT AREA. CONVECTION SHOULD CONTINUE TO OCCUR IN THIS REGION AND POSSIBLY EXPAND INTO SOUTHEAST SOUTH CAROLINA ALONG AND WEST OF THE I-95 CORRIDOR THROUGH EARLY EVENING AS BOUNDARY INTERACTIONS TAKE PLACE. STRONG INSTABILITY...WITH SBCAPE VALUES AROUND 4000 J/KG...COULD RESULT IN SOME ISOLATED PULSE SEVERE THUNDERSTORMS INTO EARLY THIS EVENING...BUT THE GREATEST DOWNDRAFT CAPE REMAINS NORTH OF THE ONGOING CONVECTION AND SHOULD LIMIT THE SEVERE POTENTIAL OVERALL. SHORT WAVE ENERGY APPROACHING FROM THE WEST AND THE STRENGTHENING LOW LEVEL JET WILL MAINTAIN NUMEROUS SHOWERS AND THUNDERSTORMS INTO THE EARLY OVERNIGHT HOURS ACROSS MUCH OF THE AREA BEFORE THE FOCUS FOR CONVECTION SHIFTS OFF THE SOUTH CAROLINA COAST LATE TONIGHT. THIS MEANS THAT COASTAL AREAS...ESPECIALLY IN SOUTHEAST SOUTH CAROLINA...COULD EXPERIENCE SOME SHOWERS DURING THE LATE NIGHT AND EARLY MORNING HOURS WITH LESSER CHANCES INLAND. DESPITE EXTENSIVE CLOUD COVER INTO THE EARLY OVERNIGHT HOURS...SOME CLEARING SHOULD OCCUR LATE TONIGHT. IT APPEARS THAT ENOUGH MOISTURE COULD BECOME TRAPPED BENEATH THE NOCTURNAL INVERSION ONCE AGAIN TO PRODUCE SOME STRATUS IN AREAS...BUT THE POTENTIAL FOR ANY SIGNIFICANT FOG APPEARS RATHER LOW GIVEN THE STRENGTHENING LOW LEVEL WIND FIELDS TONIGHT. LOWS SHOULD GENERALLY BE IN THE LOWER TO MID 70S AWAY FROM THE IMMEDIATE COAST. && .SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY/... FRIDAY AND FRIDAY NIGHT...THE DEEP CLOSED LOW TO THE NORTH WILL MEANDER ABOUT THE GREAT LAKES AS SUBTLE SHORTWAVES MOVE ACROSS THE REGION IN THE SW FLOW AROUND THE PERIPHERY OF THE LOW. THE FIRST UPPER IMPULSE SHOULD BE EXITING THE FORECAST AREA IN THE MORNING...WITH PERHAPS A PERIOD OF SOME WEAK NVA IN ITS WAKE INTO THE EARLY AFTERNOON. LATER IN THE DAY THE CHANNELED VORT ENERGY WILL APPROACH FROM THE WEST WHICH SHOULD HELP TO GET AFTERNOON CONVECTIVE COVERAGE GOING. AT THE SURFACE...THE ACTUAL FRONT WILL STILL BE FURTHER TO THE WEST AND THE REGION WILL BE CAUGHT IN THE REGION OF BROADER LOW LEVEL CONVERGENCE. CURRENT THINKING IS THAT CONVECTION WILL GET GOING ACROSS SE GA AND THEN ADVANCE TO THE NE INTO THE EVENING. I HAVE LIMITED POPS STILL IN THE 40 PERCENT RANGE AS THE BETTER FORCING AND CONVERGENCE WILL REMAIN OUTSIDE OF THE FORECAST AREA. REGARDING THE CONVECTION...OVERALL WIND FIELDS WILL BE IMPROVING AROUND THE CLOSED LOW WITH 850 MB FLOW AROUND 30 KTS AND 500 MB FLOW AROUND THE SAME. THE LIMITING FACTOR APPEARS TO BE INSTABILITY AS MODEL SOUNDINGS AND PLAN VIEW CAPES SUPPORT ONLY MODERATE VALUES AT BEST. PROFILES ARE QUITE MOIST BUT MID LEVEL LAPSE RATES ARE LIMITED. COULD SEE A COUPLE OF STRONG TO SEVERE STORMS BUT THE WIDESPREAD THREAT IS LOW. WITH THE IMPROVED LOW LEVEL FLOW...BREEZY CONDITIONS WILL BE LIKELY FOR COASTAL AREAS IN THE AFTERNOON. OVERNIGHT...THE BEST RAIN CHANCES WILL SHIFT TO THE NORTHEAST AND OFFSHORE. WITH CONSIDERABLE CLOUDINESS AROUND...HIGHS WILL BE LIMITED TO THE UPPER 80S WITH LOWS IN THE LOW TO MID 70S INLAND AND UPPER 70S ALONG THE COAST. SATURDAY THROUGH SUNDAY...THE CLOSED LOW WILL GRADUALLY LIFT NORTHWARD AS THE PRIMARY SHORTWAVE ENERGY MOVES AROUND ITS SOUTHERN PERIPHERY. A STRENGTHENING NORTH TO SOUTH ORIENTED UPPER LEVEL JET WILL PLACE THE FORECAST AREA UNDER ITS RIGHT ENTRANCE REGION DURING THE DAY INCREASING UPPER LEVEL DIVERGENCE. WITH THE IMPROVED FORCING AND THE FRONT IN CLOSER PROXIMITY...SATURDAY FEATURES THE HIGHEST POPS WHICH HAVE BEEN BUMPED UP INTO THE LIKELY CATEGORY. SIMILAR THINKING WITH THE SEVERE THREAT WITH LIMITED INSTABILITY AND THE BEST UPPER LEVEL VORT MAX PASSING BY TO THE NORTH. BY SUNDAY...THE UPPER LOW CONTINUES TO LIFT NORTHWARD AND THE TRAILING SHORTWAVE ENERGY DAMPENS OUT. MODELS SHOW GOOD AGREEMENT WITH DRYING ALOFT AND PWATS DECREASING TO AROUND 1.5 INCHES BY SUNDAY AFTERNOON. POPS HAVE BEEN CAPPED AT SLIGHT CHANCE FOR NOW AND MAY EVENTUALLY NEED TO BE LOWERED FURTHER. ANOTHER DAY WITH SUPPRESSED TEMPS ON SATURDAY WITH THE CLOUDS AND PRECIP AROUND...WHICH WILL WARM BACK INTO THE LOW 90S ON SUNDAY AS THE DEEP LAYER FLOW TURNS A BIT MORE WESTERLY WITH RISING HEIGHTS. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... A LESS AMPLIFIED UPPER LEVEL PATTERN IS EXPECTED MONDAY THROUGH THE MIDDLE OF NEXT WEEK. THE SURFACE PATTERN WILL REMAIN RELATIVELY WEAK AS WELL...WITH SUBTLE HIGH PRESSURE SETTLING OVER THE REGION MONDAY AND TUESDAY. MEDIUM RANGE MODELS ARE IN SOME DISAGREEMENT REGARDING THE TRACK OF SHORTWAVE ENERGY WITHIN THE BASE OF A WEAK UPPER TROUGH THAT WILL TAKE SHAPE ALONG THE EAST COAST LATE TUESDAY INTO THURSDAY. HAVE LIMITED PRECIPITATION CHANCES ON MONDAY AND TUESDAY...LACKING NOTABLE DEEP MOISTURE AND UPPER LEVEL SUPPORT. HAVE THEN INCREASED POPS SLIGHTLY FOR WEDNESDAY AND THURSDAY TO ACCOUNT FOR THE FORMATION OF THE BROAD UPPER TROUGH ALONG THE EAST COAST AND AN ASSOCIATED SURFACE WAVE OF LOW PRESSURE. STILL EXPECT CONVECTION TO MAINTAIN A MORE SEASONAL DIURNAL DEVELOPMENT PATTERN...WITH BEST COVERAGE DURING THE FAVORED AFTERNOON/EVENING HOURS EACH DAY. HIGH TEMPERATURES WILL GENERALLY RANGE IN THE LOWER 90S AWAY FROM THE LOCALLY COOLER COASTLINE. && .AVIATION /20Z THURSDAY THROUGH TUESDAY/... KCHS...THE COVERAGE OF SHOWERS AND THUNDERSTORMS SHOULD BE ISOLATED THROUGH MUCH OF THE AFTERNOON ACROSS COASTAL SOUTHEAST SOUTH CAROLINA SO HAVE ONLY INCLUDED VICINITY THUNDERSTORMS IN THE TAF THROUGH 00Z. A PASSING UPPER LEVEL DISTURBANCE TONIGHT SHOULD SHIFT THE FOCUS OF PRECIPITATION TO OFF THE SOUTH CAROLINA COAST...SO HAVE MAINTAINED VICINITY SHOWERS FROM 06Z-14Z. OUTSIDE OF ANY CONVECTION...VFR CONDITIONS SHOULD PREVAIL THROUGH THE PERIOD. KSAV...CONVECTION WILL CONTINUE TO INCREASE IN COVERAGE THROUGH MUCH OF THIS AFTERNOON ACROSS SOUTHEAST GEORGIA AND HAVE INCLUDED VICINITY THUNDERSTORMS IN THE TAF THROUGH EARLY EVENING. A TEMPO GROUP FOR THUNDERSTORMS WITH REDUCED CIGS/VSBYS IS ALSO IN THE TAF FROM 20-23Z. MOISTURE COULD ONCE AGAIN BECOME TRAPPED BENEATH THE NOCTURNAL INVERSION AND MVFR OR LOWER CONDITIONS ARE POSSIBLE DURING THE LATE NIGHT/EARLY MORNING HOURS...MAINLY DUE TO STRATUS AS WINDS ALOFT MAY BE TOO STRONG TO SUPPORT FOG. EXTENDED AVIATION OUTLOOK...CONDITIONS WILL REMAIN UNSETTLED THROUGH THE UPCOMING WEEKEND. BRIEF PERIODS OF MVFR OR LOWER CONDITIONS WILL BE POSSIBLE WITH ANY SHOWERS AND THUNDERSTORMS...MAINLY DURING THE AFTERNOON/EVENING HOURS. ALSO...PATCHES OF FOG AND STRATUS WILL BE POSSIBLE IN THE MORNINGS. && .MARINE... ATLANTIC HIGH PRESSURE WILL PREVAIL TONIGHT...WHILE A WEAK AREA OF LOW PRESSURE PASSES INLAND AND AN UPPER LEVEL TROUGH APPROACHES FROM THE WEST. A LOW LEVEL JET WILL DEVELOP TONIGHT OVER THE WATERS AHEAD OF THE TROUGH...CAUSING SOUTH-SOUTHWEST WINDS TO SURGE UPWARDS OF 15-20 KT ACROSS PARTS OF THE WATERS. SEAS WILL RESPOND BY BUILDING UPWARDS OF 2-4 FT BY LATE TONIGHT. FRIDAY THROUGH TUESDAY...SOUTH TO SOUTHWEST FLOW REGIME WILL CONTINUE TO DOMINATE AS THE LOCAL WATERS GET CAUGHT IN THE REGION BETWEEN HIGH PRESSURE TO THE EAST AND AN APPROACHING COLD FRONT. WITH THE TIGHTENING PRESSURE GRADIENT AND IMPROVED LOW LEVEL FLOW...WINDS OVER THE WATERS WILL BE ON THE RISE ESPECIALLY FRIDAY INTO SATURDAY. DURING PEAK MIXING FRIDAY AFTERNOON...BREEZY CONDITIONS CAN BE EXPECTED NEAR THE BEACHES INCLUDING THE CHARLESTON HARBOR. GUSTS MAY APPROACH SMALL CRAFT CRITERIA FOR THE HARBOR...BUT CONFIDENCE ISN/T HIGH ENOUGH TO GO WITH ONE YET. INTO THE OVERNIGHT...MARGINAL SMALL CRAFT CONDITIONS WILL BE POSSIBLE ACROSS MUCH OF THE WATERS WITH GUSTS POSSIBLY APPROACHING 25 KTS. SEAS WILL FEATURE A CORRESPONDING RISE DUE TO THE INCREASING WINDS WITH 5 FOOTERS POTENTIALLY GETTING INTO THE NEARSHORE WATERS. OVERALL...SEAS WILL REMAIN BELOW ADVISORY CRITERIA. AS THE FRONT CROSSES THE AREA THROUGH THE LATTER PART OF THE WEEKEND...CONDITIONS WILL BECOME MORE TRANQUIL AND THAT SHOULD LAST INTO EARLY NEXT WEEK. && .CHS WATCHES/WARNINGS/ADVISORIES...
