The episode as NWS CHS wrote it up.
Short wave moving in from NW, surface wave inland and plentiful mesoscale boundaries yet again. Storms developed into clusters and pushed off to the east and southeast. DCAPES not as high as recent days, but still supportive of strong wet microbursts.
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 30, 3:12 PM EST, 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 412 PM EDT MON JUL 30 2012 .SYNOPSIS... ATLANTIC HIGH PRESSURE WILL PREVAIL THROUGH THE WEEK WHILE A TROUGH OF LOW PRESSURE LINGERS INLAND. AN UPPER LEVEL TROUGH WITH EMBEDDED DISTURBANCES WILL LINGER OVER THE REGION THROUGH THURSDAY...AND WILL WEAKEN THROUGH THE UPCOMING WEEKEND. && .NEAR TERM /UNTIL MIDNIGHT/... A LATER AND LESS UNSTABLE START TO THE CONVECTION TODAY DUE TO THE MORNING CLOUDINESS HOLDING DOWN TEMPS. SURFACE HEATING ONLY BEGAN IN EARNEST EARLY TO MID AFTERNOON OVER PORTIONS OF SOUTHERN SC ALTHOUGH MUCH OF SOUTHEAST GA SAW PARTIAL CLEARING AND EVENTUAL DIABATIC HEATING BY LATE MORNING. ALSO...INLAND DEWPOINTS MIXED DOWN INTO THE UPPER 60S TO AROUND 70 WHICH IS LIMITING SURFACE BASED INSTABILITY. FARTHER SOUTHEAST...TEMPS HAVE WARMED INTO THE UPPER 80S...NOT AS WARM AS INLAND...BUT SFC DEWPOINTS IN THE LOWER TO MIDDLE 70S MORE THAN OFFSETTING THE LOWER TEMPS AND PRODUCING MORE SUBSTANTIAL SURFACE- BASED INSTABILITY. LATEST MESOANALYSIS SHOWING DOWNDRAFT CAPES AROUND 1000 J/KG. THE UPSTREAM SHORTWAVE WE HAVE BEEN WATCHING SINCE THIS MORNING HAS MADE SOME SOUTHEASTWARD PROGRESS ALTHOUGH IS GETTING A BIT SHEARED OUT AS IT HITS THE BOTTOM OF THE UPPER TROUGH. THIS FEATURE WILL LIKELY RESULT IN ADDITIONAL TSTM DEVELOPMENT ACROSS INTERIOR SC/GA THIS AFTERNOON WHICH WILL MIGRATE SOUTHEASTWARD THROUGH 6 PM. ANOTHER RESULT OF THE LOWER TEMPS TODAY AND THE COMPLEX MESO LOW THAT WAS SITTING ALONG THE COAST THIS MORNING IS THAT THE SEABREEZE IS NOT NEARLY AS PRONOUNCED AS YESTERDAY. NOW THAT THE SURFACE TROUGH HAS SHIFTED BACK INLAND AND LARGE SCALE SOUTHEAST FLOW HAS DEVELOPED...THE SEABREEZE HAS BEGUN TO TAKE SHAPE. ALTHOUGH CONVECTIVE DEBRIS CIRRUS IS SOMEWHAT OBSCURING OUR VIEW ON VISIBLE SATELLITE...THERE ARE HINTS ON RADAR REFLECTIVITY THAT THE BOUNDARY IS BEGINNING TO FORM ACROSS COASTAL COUNTIES. NOW THAT SOME CONVECTION HAS DEVELOPED AND THROWN OUTFLOW BOUNDARIES HITHER...THITHER...AND YON...COVERAGE OF SHOWERS AND STORMS SHOULD INCREASE DRASTICALLY IN THE NEXT COUPLE HOURS. WE ARE CARRYING LIKELY POPS MOST AREAS THROUGH EARLY THIS EVENING WITH VALUES TAPERING OFF FROM WEST TO EAST LATE EVENING. SEVERE TSTM POTENTIAL STILL SEEMS TO EXIST GIVEN 1000-1100 J/KG DCAPES...AMPLE SBCAPE AND THE APPROACHING VORT MAX. WILL MAINTAIN MENTION IN THE HAZARDOUS WEATHER OUTLOOK. && .SHORT TERM /12 AM TUESDAY MORNING THROUGH THURSDAY/... TUESDAY AND TUESDAY NIGHT...A POTENT 500 MB SHORTWAVE CURRENTLY POSITIONED NEAR THE UPPER MIDWEST IS POISED TO TRANSLATE SOUTHEASTWARD TOWARD THE AREA SETTING THE TABLE FOR A BUSY AFTERNOON/EVENING PERIOD. THE UPPER LEVEL VORT MAX IS EXPECTED TO APPROACH THE REGION BY THE EARLY AFTERNOON AND WILL BRING WITH IT A BELT OF 30-35 KT MID LEVEL FLOW PRIMARILY ACROSS SOUTHEAST GEORGIA. IN FACT...THE 12Z NAM SHOWS AN ANOMALOUSLY HIGH LOW LEVEL JET PUNCHING IN FROM THE WEST WITH 30-35 KTS OF 850 MB FLOW. GIVEN THAT THE CONVECTION IS EXPECTED TO BE ONGOING UPSTREAM OF THE REGION BY TUESDAY MORNING...IT SHOULD BE MOVING INTO THE AREA DURING THE TIME OF PEAK HEATING AND WILL BE ABLE TO MAINTAIN THE ONGOING THUNDERSTORMS AND PROVIDE A SOURCE FOR INTENSIFICATION. GIVEN THE CURRENT TIMING/TRACK OF THE SHORTWAVE...AND EXPECTED SURFACE DESTABILIZATION IT APPEARS THE BEST CHANCE FOR STRONG TO SEVERE STORMS WILL BE ACROSS SOUTHEAST GEORGIA AND LOCATIONS ALONG THE SAVANNAH RIVER IN SOUTHERN SOUTH CAROLINA. THE PRIMARY THREATS WILL COME FROM DAMAGING WIND GUSTS...ESPECIALLY GIVEN THE EXPECTED ORGANIZATION...AS WELL AS AN ISOLATED RISK OF LOCALLY EXCESSIVE RAINFALL DUE TO PWATS IN EXCESS OF 2 INCHES. POPS HAVE BEEN RAISED TO LIKELY DURING THE AFTERNOON/EVENING FOR ALL OF SOUTHEAST GEORGIA. CONVECTION COULD PERSIST THROUGH MUCH OF THE OVERNIGHT AS THE DEEP MOISTURE LINGERS ALONG THE COAST AND THE ADJACENT COASTAL WATERS. LIKELY POPS EXPAND OUTWARD TO THE WATERS AND ALONG THE SOUTH CAROLINA COAST THROUGH MUCH OF THE OVERNIGHT TO ACCOUNT FOR THIS POTENTIAL. TUESDAY HIGHS WILL LIKELY REACH THE LOW 90S AHEAD OF INCREASING CLOUD COVER FROM THE APPROACHING CONVECTION WITH LOWS IN THE LOW TO MID 70S OVERNIGHT. WEDNESDAY THROUGH THURSDAY...THE COVERAGE AND INTENSITY OF AFTERNOON/EVENING CONVECTION APPEARS TO WANE. EMBEDDED SHORTWAVE ENERGY IS CONSIDERABLY LESS THAN ON TUESDAY AND DEEP MOISTURE IS ON THE DECREASE. ALOFT...THE PERSISTENT TROF BEGINS TO WEAKEN AND WILL BECOME MORE ILL DEFINED. NO SIGNIFICANT CHANGES WERE MADE TO THE GOING FORECAST WHICH CONTINUES TO FEATURE CHANCE POPS AND TEMPS RUNNING A DEGREE OR TWO ABOVE CLIMO. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... THE UPPER TROUGH ACROSS THE EASTERN STATES WILL CONTINUE TO WEAKEN AS THE UPPER RIDGE BUILDS EASTWARD TOWARD THE REGION. THE FORECAST AREA WILL BECOME POSITIONED BETWEEN THE SURFACE HIGH PRESSURE TO THE WEST AND THE ATLANTIC HIGH PRESSURE BY THE WEEKEND. DURING THIS TRANSITION...THE PATTERN WILL BE MUCH LESS EFFECTIVE AT GENERATING PRECIPITATION. THEREFORE...HAVE POPS GENERALLY CAPPED AT 20 PERCENT FOR EACH AFTERNOON WHILE DRY CONDITIONS WILL LIKELY PERSIST DURING THE OVERNIGHT PERIODS. TEMPERATURES WILL REFLECT NORMAL SUMMERTIME HIGHS AND LOWS WITH HIGHS IN THE LOW TO MID 90S AND LOWS GENERALLY IN THE MID 70S. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... PRIMARILY VFR AT BOTH TERMINALS WITH THE EXCEPTION OF EARLY MVFR CIGS AND THUNDERSTORMS. THUNDERSTORM INITIATION TIMING IS SIMILAR TO YESTERDAY...BUT MODELS ARE SHOWING THE THUNDERSTORM ACTIVITY DIMINISHING RATHER QUICKLY...AROUND 00Z. LOW LEVEL MOISTURE HAS STUCK AROUND LONGER THAN EXPECTED...BUT SATELLITE HAS SHOWN A DRYING TREND TO THE WEST AND THAT SHOULD CONTINUE IN THE AFTERNOON AS TEMPERATURES RISE. EXTENDED AVIATION OUTLOOK...PRIMARILY VFR EXCEPT FOR SHORT-LIVED RESTRICTIONS POSSIBLE IN MAINLY AFTERNOON/EVENING SHOWERS AND THUNDERSTORMS. && .MARINE... THE OVERALL PATTERN WILL CONTINUE WITH A SUBTROPICAL HIGH PRESSURE OFF TO THE EAST AND A TROF LOW PRESSURE INLAND. THE TROF WILL MEANDER ABOUT INLAND AREAS OVER THE NEXT FEW DAYS FOLLOWED BY A CORRESPONDING TIGHTENING AND RELAXING OF THE PRESSURE GRADIENT OVER THE WATERS. AS SUCH...WINDS ARE EXPECTED TO TOP OUT IN THE 15-20 KNOT RANGE DURING NOCTURNAL SURGES AND PERIODS OF A TIGHTER PRESSURE GRADIENT. SEAS WILL ALSO INCREASE IN CONJUNCTION WITH INCREASING WINDS...BUT EXPECT CONDITIONS TO GENERALLY REMAIN BELOW SMALL CRAFT ADVISORY CRITERIA THROUGH THE FORECAST PERIOD. && .CHS WATCHES/WARNINGS/ADVISORIES...
