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 25, 2:41 PM EST, 1 hour 16 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 341 PM EDT WED JUL 25 2012 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL REMAIN SOUTH OF THE AREA THROUGH THE WEEK AS A TROUGH OF LOW PRESSURE PERSISTS INLAND. A WEAK COLD FRONT MAY APPROACH LATE IN THE WEEKEND AND LINGER ACROSS THE REGION INTO EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM THURSDAY MORNING/... ISOLATED SHOWERS AND THUNDERSTORMS ARE DEVELOPING ACROSS SOUTHEAST GEORGIA ...MAINLY ALONG THE SEA BREEZE...WITH BETTER COVERAGE SOUTH OF THE ALTAMAHA RIVER WHERE THE CAP IS WEAKER AND TEMPERATURES ARE NEAR 100 DEGREES. CLOUD COVER ASSOCIATED WITH A MORNING MCS HAS MOVE ACROSS SOUTHERN SOUTH CAROLINA KEEPING TEMPERATURES DOWN...ALTHOUGH HIGHER DEWPOINTS HAVE COMPENSATED SOMEWHAT TO YIELD MODERATE INSTABILITY...ESPECIALLY ALONG THE COAST. EXPECT SCATTERED SHOWERS AND THUNDERSTORMS THIS EVENING...MAINLY AWAY FROM THE IMMEDIATE COAST AS THE SEA BREEZE SLOWLY MOVES INLAND...POSSIBLY COMBINING WITH OUTFLOW FROM THUNDERSTORMS TO THE SOUTH AND WEST. OVERALL THE BEST COVERAGE SHOULD BE ACROSS SOUTHEAST GEORGIA WHERE THE GREATER INSTABILITY IS FOUND AND THIS IS WHERE WE HAVE THE HIGHEST RAIN CHANCES. ONE CAVEAT TO THE FORECAST IS THE POTENTIAL FOR AN ORGANIZED CLUSTER OF STORMS TO DEVELOP ACROSS UPSTATE SC AND MAKE A RUN TOWARD THE COAST THIS EVENING AS SOME OF THE HIGH- RES WRF MODELS INDICATE. HOWEVER THERE IS NOT MUCH SIGN OF THIS YET SO CONFIDENCE IS LOW IN THIS SOLUTION COMING TO FRUITION. MILD LOWS AGAIN IN THE MID TO UPPER 70S...ALTHOUGH POSSIBLY COOLER WHERE RAIN OCCURS. && .SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/... THE UPPER RIDGE IS EXPECTED TO WEAKEN AND SHIFT EAST AS AN UPPER TROUGH APPROACHES FROM THE WEST. LOW-LEVEL FLOW WILL SHIFT FROM NORTHWEST TO WEST-SOUTHWEST...RESULTING IN A PERIOD OF HOT AND HUMID CONDITIONS. THE WESTERLY LOW-LEVEL WIND COMPONENT WILL KEEP THE SEABREEZE PINNED NEAR THE COASTLINE UNTIL MID TO LATE AFTERNOON. THE PRIMARY SURFACE FEATURE WILL BE THE INLAND LEE TROUGH ALTHOUGH A SURFACE FRONT COULD DROP TOWARD THE AREA DURING THE DAY SATURDAY. DAYTIME CONVECTION WILL PROBABLY NOT INITIATE UNTIL THE AFTERNOON HOURS AND REMAIN RATHER ISOLATED THURSDAY AND FRIDAY. A BIT MORE COVERAGE POSSIBLE ON SATURDAY WITH THE APPROACHING COLD FRONT. WITH HIGH TEMPS PROGGED TO REACH THE UPPER 90S THURSDAY AND FRIDAY... COMBINED WITH DEWPOINTS WELL INTO THE 70S...HEAT INDICES COULD REACH 110F IN SPOTS EITHER DAY. MOS OUTPUT INDICATES UPPER 70S DEWPOINTS IN MOST AREAS THURSDAY AFTERNOON. HOWEVER NAM MODEL SOUNDINGS INDICATE SOME DRIER AIR MIXING DOWN DURING THE HOURS OF PEAK HEATING AND SURFACE DEWPOINTS DROPPING INTO THE LOWER 70S IN MANY LOCATIONS. THIS WOULD KEEP HEAT INDICES JUST BELOW 110F. ALTHOUGH CHANCES ARE RELATIVELY HIGH THAT A HEAT ADVISORY WILL EVENTUALLY BE NEEDED...WE WILL LEAVE THE DECISION TO THE MIDNIGHT SHIFT AND ALLOW ANOTHER LOOK AT DEWPOINT PROGS/TRENDS. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... THE OVERALL PATTERN IN THE LONG TERM FORECAST PERIOD FAVORS A TROF ALONG MUCH OF THE EASTERN SEABOARD THAT ORIGINATES FROM A DEEP CLOSED LOW POSITIONED NEAR HUDSON BAY. AT THE SURFACE THE PATTERN IS A BIT MORE QUESTIONABLE...WITH THE UNCERTAINTY REVOLVING AROUND THE POSSIBILITY OF A COLD FRONT CROSSING THE AREA OR LINGERING IN THE VICINITY. CURRENT RUNS OF THE ECMWF AND THE GFS TEND TO FAVOR A CLEAN FRONTAL PASSAGE...WHICH CLIMATOLOGICALLY ISN/T THE FAVORED SOLUTION. IF THE FRONT WERE TO STALL OUT ACROSS THE AREA EARLY NEXT WEEK...IT WOULD STAND TO REASON THAT THE CONVECTIVE ACTIVITY COULD BE ON THE INCREASE. DUE TO THE UNCERTAINTY AT THIS POINT...THE FORECAST FEATURES SLIGHT CHANCE TO CHANCE POPS THROUGH THE PERIOD. WITH THE TROF ALOFT AND LOWERING HEIGHTS...TEMPS FEATURE A DOWNWARD TREND CLOSER TO CLIMO VALUES OF LOWER 90S BY THE END OF THE PERIOD. && .AVIATION /20Z WEDNESDAY THROUGH MONDAY/... WE HAVE FORECAST VFR CONDITIONS FOR BOTH KSAV AND KCHS WITH MAINLY MID TO LATE AFTERNOON CHANCES FOR TSTMS...WITH THE THREAT DIMINISHING BY 00Z...PROBABLY EARLIEST AT KCHS. HOWEVER...THERE IS A SMALL RISK THAT ANOTHER ORGANIZED CLUSTER OF STORMS DEVELOPS UPSTREAM ACROSS NORTHERN SC AND HEADS SOUTHEAST TOWARD THE COAST THIS EVENING AND THIS WOULD EXTEND THE THREAT OF SHOWERS AND TSTMS LONGER THAN CURRENTLY ADVERTISED. EXTENDED AVIATION OUTLOOK...PRIMARILY VFR EXCEPT FOR SHORT-LIVED RESTRICTIONS POSSIBLE IN AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS. && .MARINE... THROUGH TONIGHT...S/SW FLOW TO DOMINATE WITH WINDS MAINLY 15 KT OR LESS AND SEAS 4 FT OR LESS. SMALL CHANCE THAT A CLUSTER OF TSTMS COULD PUSH OFFSHORE THIS EVENING SO MARINERS SHOULD BE ALERT FOR WORSE CONDITIONS THAN FORECAST. THURSDAY THROUGH SUNDAY...THE GENERAL PATTERN OF A SURFACE TROF INLAND AND HIGH PRESSURE OFF TO THE E AND SE WILL REMAIN THE SAME INTO THE WEEKEND. THE PRESSURE GRADIENT WILL TIGHTEN AND LOOSEN THROUGH THE PERIOD AS THE TROF MEANDERS ABOUT THE CENTRAL CAROLINAS. PERIODS OF 15-20 KNOT FLOW WILL BE POSSIBLE...ESPECIALLY DURING OVERNIGHT SURGES AND THE COASTAL SEA BREEZE...BUT THE LIKELIHOOD OF SMALL CRAFT ADVISORIES APPEARS LOW. SEAS WILL BE A MIXTURE OF SHORT PERIOD WIND DRIVEN WAVES AND LONGER PERIOD SWELL WAVES...WITH THE RESULTING COMBINED SEAS MOSTLY HELD AT OR BELOW 4 OR 5 FT. && .CHS WATCHES/WARNINGS/ADVISORIES...
