The episode as NWS CHS wrote it up.
The approach of a cold front and strong short wave trough in a moderately unstable air mass, resulted in the development of scattered to numerous thunderstorms across southern South Carolina and 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 Jul 9, 2:50 PM EST, 1 hour 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 350 PM EDT SAT JUL 9 2011 .SYNOPSIS... A WEAK COLD FRONT WILL DROP INTO THE AREA TONIGHT AND SUNDAY...STALLING OVER THE AREA BEFORE DISSIPATING ON MONDAY. ANOTHER FRONT WILL APPROACH FROM THE NORTH LATE NEXT WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... A PRONOUNCED ALBEIT ELONGATED SHORTWAVE WAS SEEN ON WATER VAPOR IMAGERY THIS AFTERNOON DROPPING INTO NORTH CENTRAL SC. THIS FEATURE IS ENTERING A REGION OF ENHANCED MIXED-LAYER CAPE THAT HAS DEVELOPED OVER INTERIOR SC. APPROXIMATELY 3000-3500 JOULES ARE CURRENTLY SHOWING UP ON THE SPC MESOANALYSIS. MID-LEVELS REMAIN VERY WARM WHICH WILL LIMIT HAIL GROWTH. HOWEVER WITH ROBUST CAPE VALUES...FAIRLY BEEFY CORES WILL BE ABLE TO DEVELOP WHICH CAN PRODUCE ISOLATED DAMAGING WIND GUSTS WHEN THEY COLLAPSE. EARLIER TODAY WE SAW SCATTERED COVERAGE OF SHOWERS AND THUNDERSTORMS...INCLUDING A STORM THAT MOVED OVER THE CHARLESTON AIRPORT. VISIBLE SATELLITE HAS SHOWED MOST OF THE CUMULUS FIELD DISSOLVED IN SOUTHEAST GA AS EARLIER OUTFLOWS STABILIZED THE BOUNDARY LAYER. A DECENT CU FIELDS REMAINS ACROSS SOUTHERN SC WHILE SEVERAL CLUSTERS OF STRONG THUNDERSTORMS MOVE IN FROM THE NW. BEST PRECIP CHANCES WILL BE IN SOUTHERN SC THROUGH MID EVENING AS THE INCREASINGLY ORGANIZED UPSTREAM CONVECTION CONGEALS AND MOVES SOUTHEAST WITH THE SHORTWAVE. LATER THIS EVENING AND OVERNIGHT WE MAINTAINED 20-30 POPS FOR SHOWERS OR STORMS THAT POP AHEAD OF THE SHORTWAVE. HOWEVER WITH THE LOSS OF DAYTIME HEATING THE COVERAGE SHOULD BE SUBSTANTIALLY LOWER. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH TUESDAY/... SUNDAY...A REMNANT BOUNDARY WILL EXTEND EAST/WEST ACROSS SOUTHEAST GEORGIA WHILE A WEAK MID LVL LOW LINGERS ALONG THE SC/GA COASTLINE. A SLIGHT CHANCE TO CHANCE OF SHOWERS AND THUNDERSTORMS ARE FORECAST SUNDAY AFTERNOON...MAINLY FOR AREAS SOUTH OF THE SAVANNAH RIVER...AS WEAK AREAS OF LOW PRESSURE DEVELOP ALONG THE REMAINING BOUNDARY. PWATS BETWEEN 2-2.5 INCHES...DEWPTS IN THE MID 70S...AND A WEAK SHEAR ENVIRONMENT...SUGGEST SCATTERED PULSE TYPE CONVECTION WITH HEAVY RAINFALL BEING THE PRIMARY THREAT. CAN NOT RULE OUT AN ISOLATED STRONG WIND GUST FROM THUNDERSTORMS NEAR THE REMNANT BOUNDARY AS SBCAPES APPROACH 2500 J/KG. SHOWER/THUNDERSTORM ACTIVITY WILL LIKELY DIMINISH SUNDAY EVENING AS THE SFC BOUNDARY WASHES OUT AND MID LVL RIDGING BUILDS OVER THE REGION FROM THE WEST. 1000-850MB THICKNESS VALUES SUPPORT LOW/MID 90S FOR HIGHS SUNDAY...WITH HIGHEST TEMPS OVER INLAND PORTIONS OF SC AND GA. THERE IS POTENTIAL FOR HEAT ADVISORY CONDITIONS WEST OF INTERSTATE 95 SHOULD DEWPTS REMAIN IN THE MID 70S DURING AFTERNOON HOURS. OVERNIGHT LOWS WILL BE IN THE LOW 70S...WITH MID/UPPER 70S ALONG THE IMMEDIATE COASTLINE. MONDAY AND TUESDAY...THE MAIN CONCERN EARLY NEXT WEEK WILL BE THE POTENTIAL FOR SOLID HEAT ADVISORY CONDITIONS. 1000-850MB THICKNESS VALUES SUPPORT OVERALL HIGH TEMPS IN THE MID/UPPER 90S OVER INLAND AREAS AS SFC HIGH PRESSURE BUILDS IN FROM THE NORTH WHILE A STRONG MID LVL RIDGE BECOMES CENTERED OVER THE SOUTHEAST. WITH SFC DEWPTS REMAINING IN THE LOW 70S DURING PEAK HEATING HOURS...HEAT INDEX VALUES BETWEEN 105 TO 110 ARE POSSIBLE. SHOULD EXPECTED CONDITIONS PERSIST A HEAT ADVISORY WILL LIKELY BE NEEDED FOR MONDAY AND TUESDAY AFTERNOON. OVERNIGHT LOWS WILL BE IN THE MID 70S...WITH UPPER 70S ALONG THE COAST. A SLIGHT CHANCE TO CHANCE OF SHOWERS/THUNDERSTORMS ARE FORECAST MONDAY AND TUESDAY WITH HIGHEST POPS OVER EXTREME SOUTHERN PORTIONS OF THE CWA WHERE PWATS BETWEEN 1.5 TO 2 INCHES RESIDE. OVERALL COVERAGE WILL BECOME LESS MONDAY THROUGH TUESDAY AS THE MID LVL RIDGE REMAINS OVER THE SOUTHEAST. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... WEDNESDAY WILL BE ANOTHER VERY WARM DAY WITH HEAT INDICES IN EXCESS OF 100...ALTHOUGH THERE LOOKS TO BE A SLIGHTLY BETTER CHANCE FOR DIURNAL CONVECTION...GIVING A FEW PLACES SOME TEMPORARY COOLING...AS MID LEVEL MOISTURE BEGINS TO RETURN AND THE UPPER LEVEL RIDGE SLOWLY WEAKENS. THE GFS IS MOST AGGRESSIVE WITH THE CHANCES OF PRECIP...BUT EVEN THE SLOWER ECMWF INDICATES SOME THUNDERSTORM ACTIVITY DURING THE TIME OF AFTERNOON MAXIMUM HEATING. TIMING DIFFERENCES BETWEEN THE MODELS MAKE THE END OF THE WEEK SOMEWHAT DIFFICULT FOR DETAILS...BUT THE GENERAL CONCEPT OF A STRONGER FRONT MOVING THROUGH IS SIMILAR. FOR NOW...I AM GOING WITH THE FRONT PASSING THROUGH THE CWA DURING THE DAY ON THURSDAY FROM NORTH TO SOUTH...BUT I COULD BE BRINGING IT THROUGH A BIT QUICK IF THE ECMWF/GEM SOLUTION TURN OUT TO BE BETTER. IN ANY CASE...THE CHANCE OF PRECIP INCREASES AGAIN WITH THE FRONT ON THURSDAY INTO THURSDAY EVENING. THE GFS INDICATES SOME DRYING AND SLIGHT COOLING FOR FRIDAY AND SATURDAY BEHIND THE FRONT...AND I HAVE FOLLOWED THIS SOLUTION FOR NOW. IF THE FRONT IS SLOWER...HOWEVER...I MAY BE COOLING OFF THE OVERNIGHT MINS TOO QUICKLY IN THE CURRENT FORECAST. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... SHOWERS/STORMS SHOULD INCREASE IN COVERAGE THROUGH THE AFTERNOON AND INTO EARLY THIS EVENING AS A SHORTWAVE TROUGH DROPS IN FROM THE NORTH AND THE SEABREEZE INTERACTS WITH RESIDUAL BOUNDARIES. LOOKS LIKE BETTER CHANCES AT KCHS SO WE ADDED A TEMPO LATER THIS AFTERNOON FOR SOME TSRA. LATER TONIGHT WE COULD SEE A BIT OF FOG DEVELOPMENT GIVEN THE WET SOIL. WILL HOLD OFF ON VSBY RESTRICTIONS UNTIL WE CAN BETTER PIN DOWN TIMING. EXTENDED AVIATION...MVFR/IFR CIGS/VSBYS POSSIBLE DURING THUNDERSTORMS SUNDAY AFTERNOON...MAINLY FOR THE KSAV TERMINAL. MVFR VSBY/CIGS THEN POSSIBLE AT KSAV DURING EARLY MORNING HOURS DUE TO SMOKE FROM FIRES FROM THE WEST. && .MARINE... WINDS AND SEAS WILL REMAIN BELOW SCA CRITERIA LATE THIS WEEKEND INTO EARLY NEXT WEEK. IN GENERAL S/SE WINDS WILL REMAIN AT OR BELOW 15 KTS...WITH PEAK WINDS ALONG THE COAST DURING AFTERNOON SEABREEZE CIRCULATIONS MONDAY AND TUESDAY. SEAS BETWEEN 3 TO 4 FT WILL SUBSIDE TO 2 TO 3 FT BY SUNDAY NIGHT WITH LITTLE CHANGE THROUGH EARLY NEXT WEEK. A CHANCE OF SHOWERS AND THUNDERSTORMS ARE POSSIBLE SUNDAY ALONG A REMNANT BOUNDARY EXTENDING ACROSS THE COASTAL WATERS. ACTIVITY WILL LESSEN MONDAY AND TUESDAY AS THE BOUNDARY WEAKENS. WINDS WILL PICK UP A BIT AGAIN ON WEDNESDAY AHEAD OF THE NEXT FRONT. WINDS MAY BE BACK INTO THE 15 TO 20 KNOT RANGE FROM THE NORTHEAST OR EAST BEHIND THE FRONT LATE IN THE WEEK...BUT THE TIMING IS SOMEWHAT UNCERTAIN AT THIS POINT. && .CHS WATCHES/WARNINGS/ADVISORIES...
