The episode as NWS CHS wrote it up.
A weak wave of Low Pressure and a mid level trough supported widespread convection.
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 31, 2:55 PM EST, 2 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 355 PM EDT WED JUL 31 2013 .SYNOPSIS... A WEAK WAVE OF LOW PRESSURE AND A MID TO UPPER LEVEL TROUGH WILL PERSIST THROUGH THURSDAY. HIGH PRESSURE WILL SLOWLY STRENGTHEN FRIDAY AND SATURDAY. A FRONT WILL DROP INTO THE AREA SUNDAY THEN LINGER NEARBY THROUGH THE MIDDLE OF NEXT WEEK. && .NEAR TERM /THROUGH TONIGHT/... LATEST WATER VAPOR IMAGERY SHOWS THE ROBUST UPPER SHORTWAVE DIVING SOUTHEAST TOWARD THE SOUTH CAROLINA AND GEORGIA COASTLINES THIS AFTERNOON. THIS FEATURE BRINGS ENHANCED FORCING FOR ASCENT AND...ALONG WITH THE PRESENCE OF A LINGERING STATIONARY FRONT AND SURFACE TROUGH...HAS PROVIDED THE NECESSARY INGREDIENTS TO INITIATE CONVECTION ACROSS PORTIONS OF THE FORECAST AREA. CONVECTIVE COVERAGE IS A COMBINATION OF BOTH SEABREEZE AND MESOSCALE BOUNDARY CONVERGENCE...WITH INLAND AREAS SEEING ACTIVITY AS WELL AS COASTAL LOCATIONS. DEEP MOISTURE WILL STEADILY INCREASE INTO THE EVENING AND OVERNIGHT HOURS...PEAKING JUST UNDER 2 INCHES IN PRECIPITABLE WATER VALUES. CONSIDERING LIGHT LOW LEVEL WIND FIELDS...STORM MOTIONS WILL BE SLOW AND ALLOW STRONGEST CONVECTION TO PRODUCE HEAVY DOWNPOURS AND POSSIBLY LOCALIZED FLOODING. IN ADDITION...AN ISOLATED SEVERE THUNDERSTORM COULD OCCUR WHERE BOUNDARY INTERACTIONS ENHANCE UPDRAFT STRENGTH. THE MAIN FORECAST CONCERN INTO THE NIGHTTIME PERIOD IS THE PERSISTENCE AND/OR REDEVELOPMENT OF CONVECTION. NUMERICAL MODELS ARE ACTUALLY IN DECENT AGREEMENT INDICATING THE AXIS OF THE SHORTWAVE TROUGH CROSSING THE COASTLINE AFTER MIDNIGHT AND MAINTAINING THE NECESSARY FORCING AND DEEP MOISTURE FOR CONTINUED CONVECTIVE POTENTIAL. IN FACT...SOME MODEL SOLUTIONS SUGGEST THAT THE BEST COVERAGE COULD OCCUR OVERNIGHT...ESPECIALLY ACROSS THE NORTHERN HALF OF THE FORECAST AREA CLOSEST TO THE VORTICITY MAXIMA. WILL THUS ADVERTISE RAIN CHANCES UP TO 60 PERCENT THIS AFTERNOON AND EVENING...WITH A SLIGHT DECREASE IN POTENTIAL ACROSS SOUTHERN ZONES BY MIDNIGHT. THICK CLOUD COVER WILL LINGER THROUGH THE NEAR TERM PERIOD. ALTHOUGH A FEW LOCATIONS THAT RECEIVE ABUNDANT RAINFALL COULD SEE SOME PATCHY FOG DURING THE EARLY MORNING HOURS...LINGERING THICK CLOUD COVER SHOULD SUPPRESS MORE WIDESPREAD FOG DEVELOPMENT. LOW TEMPERATURES TONIGHT WILL RANGE FROM THE LOW 70S INLAND TO THE MID 70 CLOSER TO THE COAST. && .SHORT TERM /THURSDAY THROUGH SATURDAY/... THURSDAY...MID LVL RIDGING WILL REMAIN OVER THE SOUTH CENTRAL UNITED STATES WHILE A TROUGH OF LOW PRESSURE SHIFTS OVER THE MID ATLANTIC AND SOUTHEASTERN STATES BEHIND A H5 SHORTWAVE POSITIONED JUST OFFSHORE. DESPITE THE POSITION OF THE H5 SHORTWAVE...CHANCES OF SHOWERS/THUNDERSTORMS WILL LIKELY INCREASE IN COVERAGE OVER LAND AS DIFFLUENCE INCREASES WITH THE APPROACH OF A H25 JET UPSTREAM AND THE SFC TROUGH BECOMES ELONGATED OVER THE SOUTHEAST. EXPECT COVERAGE TO PEAK LATE MORNING INTO EARLY AFTERNOON AS HIGH TEMPS REACH THE MID/UPPER 80S UNDER MOSTLY CLOUDY SKIES. THE POSITION OF THE SFC TROUGH SUGGESTS THAT MOST PRECIP SHOULD OCCUR CLOSER TO THE COAST DURING THE PERIOD...BEFORE GRADUALLY SHIFTING OFFSHORE BY THURSDAY NIGHT. WEAK WIND FIELDS AND PWATS BETWEEN 2.0 TO 2.25 INCHES FAVOR SLOW MOVING SHOWERS AND THUNDERSTORMS CAPABLE OF PRODUCING HEAVY RAINFALL. OVERNIGHT LOWS SHOULD RANGE BETWEEN THE LOW 70S INLAND TO MID/UPPER 70S ALONG THE COAST. FRIDAY...COVERAGE OF SHOWERS AND THUNDERSTORMS WILL QUICKLY DECREASE IN COVERAGE FRIDAY MORNING AS THE SFC TROUGH SLIDES OFFSHORE AND IS FOLLOWED BY SFC HIGH PRESSURE TO OUR NORTHWEST AND MID LVL RIDGING FROM THE WEST. CONDITIONS WILL BE CONSIDERABLY DRYER FRIDAY AFTERNOON AND EVENING AS A NORTHWEST DOWNSLOPING WIND SETS UP OVER THE AREA. HAVE THEREFORE INDICATED HIGHEST POPS ALONG THE GEORGIA COAST WHILE SHOWING A GRADUAL DECREASE OF POPS INLAND WHERE DRYER AIR WILL ENTER THE REGION FIRST. OVERALL HIGH TEMPS SHOULD BE A FEW DEGREES WARMER THAN PREVIOUS DAYS GIVEN THE DOWNSLOPING WIND COMPONENT OVER THE REGION. EXPECT OVERALL TEMPS TO RANGE IN THE UPPER 80S TO LOWER 90S. OVERNIGHT LOWS SHOULD RANGE BETWEEN THE LOW 70S INLAND TO MID/UPPER 70S ALONG THE COAST. SATURDAY...SFC HIGH PRESSURE WILL GRADUALLY WEAKEN OVER THE REGION AS ANOTHER SFC TROUGH OF LOW PRESSURE DEVELOPS TO OUR NORTH AND EXPANDS OVER THE CAROLINAS DURING THE EVENING. WITH THIS SETUP IN MIND...EXPECT SHOWER AND THUNDERSTORM ACTIVITY TO REMAIN MINIMAL DURING MORNING HOURS INTO EARLY AFTERNOON...BEFORE GRADUALLY INCREASING LATE AFTERNOON AND EVENING AS THE TROUGH EXPANDS OVER THE REGION. THE GREATEST CHANCE OF RAINFALL APPEARS TO BE OVER INLAND SOUTH CAROLINA LOCATIONS AS A WEAK H5 SHORTWAVE POSSIBLY SHIFTS OVER THE FORECAST AREA LATE. 1000-850MB THICKNESSES SUGGEST OVERALL HIGH TEMPS IN THE UPPER 80S ALONG THE COAST...AND LOWER 90S FOR MOST LOCATIONS AWAY FROM THE COAST. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... MEDIUM RANGE GUIDANCE IS IN FAIRLY GOOD AGREEMENT WITH THE OVERALL SYNOPTIC PATTERN ALOFT...BUT DIFFER SOMEWHAT WITH RESPECT TO SURFACE FEATURES LEADING TO SLIGHTLY LOWER CONFIDENCE. MID AND UPPER LEVEL RIDGING IN PLACE OVER THE REGION WILL BEGIN TO ERODE LATE IN THE WEEKEND AND INTO EARLY NEXT WEEK AS A TROUGH DIGS ACROSS THE EASTERN SEABOARD AND BECOMES THE DOMINANT WEATHER FEATURE INTO THE MIDDLE OF NEXT WEEK. MEANWHILE AT THE SURFACE...A BACKDOOR COLD FRONT WILL SHIFT INTO THE AREA SUNDAY NIGHT INTO MONDAY AS THE UPPER TROUGH DIGS...THEN LINGER OVER THE AREA OR AT LEAST NEARBY INTO THE MIDDLE OF NEXT WEEK AS SEVERAL WAVES OF LOW PRESSURE TRACK ALONG THE BOUNDARY. THIS PATTERN APPEARS TO FAVOR WETTER THAN NORMAL CONDITIONS...WITH A CHANCE OF SHOWERS AND THUNDERSTORMS IN THE FORECAST THROUGHOUT THE LONG TERM PERIOD. SUNDAY COULD BE THE WARMEST DAY OF THE WEEK AS COMPRESSIONAL HEATING AND A DOWNSLOPE FLOW PROVIDE FOR ABOVE NORMAL TEMPERATURES. THEN EARLY NEXT WEEK...HIGH TEMPERATURES WILL BE NEAR TO SLIGHTLY BELOW NORMAL. && .AVIATION /19Z WEDNESDAY THROUGH MONDAY/... ONGOING SHOWERS/THUNDERSTORMS ARE EXPECTED TO EXPAND IN COVERAGE AS THE AFTERNOON PROGRESSES. INITIAL ACTIVITY HAS DEVELOPED CLOSER TO KCHS...AND WILL THUS INITIALIZE THE 18Z TAF WITH A TEMPO GROUP FOR MVFR CONDITIONS WITHIN TSRA. CEILINGS/VISIBILITIES COULD FALL BELOW MVFR LEVELS IF THUNDERSTORMS INTENSIFY AND LINGER...SO AMENDMENTS MAY BE NEEDED. THERE IS LESS CERTAINTY REGARDING NEAR TERM TIMING OF CONVECTIVE IMPACTS AT KSAV...AND PREFER TO MAINTAIN A VCTS UNTIL TRENDS BECOME MORE APPARENT IN THE NEXT HOUR OR TWO. NUMERICAL MODEL SOLUTIONS THEN SUGGEST THAT SHOWERS/THUNDERSTORMS COULD PERSIST OR RE-INITIATE OVERNIGHT...AS ROBUST UPPER LEVEL ENERGY CONTINUES TO MOVE THROUGH THE REGION. FURTHER EXAMINATION SUGGESTS A SLIGHTLY HIGHER POTENTIAL TO THE NORTH NEAR KCHS THAN FARTHER SOUTH TOWARD KSAV. WILL ADD A PROB30 GROUP AT KCHS DURING THE EARLY MORNING HOURS WHEN FORCING FOR ASCENT IS MAXIMIZED...WHILE INCLUDING JUST A VCSH AT KSAV FOR THE SAME TIME FRAME. MODEL GUIDANCE ALSO HINT AT POTENTIAL MVFR OR LOWER CEILINGS OUTSIDE OF THUNDERSTORM OVERNIGHT...YET DUE TO UNCERTAINTY...WILL MAINTAIN VFR CEILINGS AND SCATTER IN LOWER CLOUDS. CONVECTION WILL BE A CONCERN THROUGH THURSDAY AFTERNOON...HOWEVER TIMING AND DURATION PRECLUDES SPECIFIC MENTION IN THE TAFS. EXTENDED AVIATION OUTLOOK...PERIODIC RESTRICTIONS IN CIGS/VSBYS ARE POSSIBLE FROM AFTERNOON SHOWERS AND TSTMS ON THURSDAY. VFR CONDITIONS ARE THEN EXPECTED AT BOTH TERMINALS THURSDAY NIGHT THROUGH SUNDAY MORNING. PERIODIC RESTRICTIONS IN CIGS/VSBYS ARE THEN POSSIBLE SUNDAY AND MONDAY AS A FRONT APPROACHES AND STALLS OVER THE AREA EARLY NEXT WEEK. && .MARINE... TONIGHT...LIGHT SOUTH/SOUTHEAST WINDS THIS AFTERNOON WILL BECOME MORE SOUTH/SOUTHWEST OVERNIGHT. IN ADDITION...EXPECT A SLIGHT INCREASE IN WIND SPEEDS AS THE GRADIENT TIGHTENS SLIGHTLY BETWEEN AN INLAND SURFACE TROUGH AND ATLANTIC HIGH PRESSURE. WINDS AND SEAS WILL REMAIN WELL BELOW SMALL CRAFT ADVISORY THRESHOLDS...HOWEVER CONDITIONS COULD DETERIORATE WITHIN ANY THUNDERSTORMS IMPACTING THE MARINE ZONES. THURSDAY THROUGH MONDAY...CONDITIONS WILL REMAIN BELOW SMALL CRAFT ADVISORY LEVELS WITH ATLANTIC HIGH PRESSURE OVER THE WATERS INTO EARLY THURSDAY. IN GENERAL...SOUTHERLY WINDS WILL REMAIN AT OR BELOW 15 KT WHILE SEAS RANGE BETWEEN 2-4 FT...HIGHEST IN OFFSHORE GEORGIA WATERS. SOUTHERLY WINDS MAY APPROACH 15-20 KT OVER NORTHERN SC WATERS AS THE PRESSURE GRADIENT BECOMES ENHANCED BETWEEN ATLANTIC HIGH PRESSURE TO THE EAST AND A SFC TROUGH ALONG THE SOUTHEAST COAST THURSDAY AFTERNOON AND EVENING. NUMEROUS SHOWERS AND THUNDERSTORMS WILL ALSO BE POSSIBLE OVER THE WATERS THROUGH THURSDAY EVENING AS THE TROUGH OF LOW PRESSURE GRADUALLY SLIDES OFFSHORE. CONDITIONS WILL REMAIN RELATIVELY QUIET UNTIL A BACKDOOR COLD FRONT IS EXPECTED TO DROP INTO THE WATERS SUNDAY NIGHT INTO MONDAY. DESPITE POSSIBLE FROPA...CONDITIONS ARE STILL EXPECTED TO REMAIN BELOW SMALL CRAFT ADVISORY THRESHOLDS OVER THE WEEKEND AND INTO EARLY NEXT WEEK WITH WIND SPEEDS GENERALLY AROUND 15 KT OR LESS AND SEAS RANGING BETWEEN 2-4 FT...HIGHEST IN OFFSHORE GEORGIA WATERS. && .CHS WATCHES/WARNINGS/ADVISORIES...
