The episode as NWS CHS wrote it up.
Under the influence of a persistent upper low, scattered pulse severe thunderstorms developed.
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 May 17, 9:30 AM EST, 4 hours 40 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 1030 AM EDT THU MAY 17 2012 .SYNOPSIS... A WEAK AREA OF LOW PRESSURE WILL LINGER ACROSS THE REGION INTO TONIGHT. HIGH PRESSURE WILL BUILD SOUTHWARD INTO THE REGION ON FRIDAY AND WILL LINGER ALONG THE EASTERN SEABOARD THROUGH THE WEEKEND. THE HIGH WILL DISSIPATE MONDAY AND TUESDAY AND A WEAK COLD FRONT WILL APPROACH FROM THE NORTHWEST BY THE MIDDLE OF NEXT WEEK. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... A COMPLEX SETUP TODAY DUE TO A PERSISTENT UPPER LOW JUST TO THE WEST AND VARIOUS SURFACE BOUNDARIES IN PLACE. THE AIRMASS REMAINS QUITE MOIST WITH PRECIPITABLE WATER READINGS ON THE 12Z CHS RAOB AT 1.57 INCHES. 0-6 KM MEAN WIND IS ONLY 10 KT SO CONVECTION WILL BE VERY SLOW-MOVING. SO FAR TODAY THERE IS QUITE A BIT OF LOW AND MID LEVEL CLOUDINESS WHICH IS SLOWING SURFACE HEATING. ALTHOUGH SOME SHOWERS ARE MOVING INTO WESTERN ZONES IN ASSOCIATION WITH THE UPPER LOW...WE THINK AN INITIAL FOCUS FOR MORE WIDESPREAD SHOWERS AND THUNDERSTORMS WILL BE THE CHARLESTON TRI-COUNTY. THE NAM SHOWS AN AREA OF ENHANCED UPPER JET DIVERGENCE SHIFTING INTO SOUTHERN SC TOWARD 18Z...COINCIDENT WITH A POTENT SHORTWAVE. ADDITIONALLY A WEAK SURFACE TROUGH IS DRAPED ACROSS SOUTHERN SC WHICH COULD PROVIDE A TRIGGER FOR CONVECTION. WE INCREASED POPS TO LIKELY OVER OUR NORTHERN ZONES LATER THIS AFTERNOON WITH AN ACROSS THE BOARD INCREASE ELSEWHERE PER RADAR TRENDS SHOWING ACTIVITY BEGINNING TO POP UP JUST ABOUT EVERYWHERE. SEVERE WEATHER POTENTIAL LOOKS QUITE LOW ALTHOUGH HEAVY RAINFALL COULD BE AN ISSUE IN SPOTS. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/... SURFACE HIGH PRES BUILDING N OF THE REGION TONIGHT WILL NUDGE THE SYNOPTIC SCALE BOUNDARY TO THE S OF OUR FORECAST AREA. THE ATMOSPHERE DOES NOT REALLY DRY OUT TOO MUCH AND WE THINK CLOUDS AND PERHAPS SOME SHOWERS AND TSTMS MANY REDEVELOP ALONG SOME OF OUR COASTAL AREAS ONCE AGAIN LATE BUT THE CONVERGENCE PATTERN IS NOT NEARLY AS STRONG WITH NE FLOW. THE MID LEVEL LOW LOOKS TO STALL ACROSS EASTERN SOUTH CAROLINA AND MODELS INDICATE SHOWERS MAY PERSIST ALONG COASTAL SOUTH CAROLINA AFTER MIDNIGHT. FRIDAY AND FRIDAY NIGHT...THE LINGERING 500 MB TROF/CLOSED UPPER LOW WILL SIT DIRECTLY OVER THE SOUTHEAST COAST AND IS EXPECTED TO ONLY MEANDER VERY SLIGHTLY. AT THE SURFACE...LOW LEVEL RIDGING WILL BECOME WELL ESTABLISHED ACROSS THE FORECAST AREA WITH A PINCHED PRESSURE GRADIENT AND PERSISTENT NE FLOW. MODEL SOLUTIONS SEEM TO BE FAVORING SE GA AND THE IMMEDIATE COAST FOR THE BEST PRECIP COVERAGE...WHICH LINES UP WELL WITH THE BEST SURFACE HEATING AND LOW LEVEL CONVERGENCE. WILL STICK WITH SLIGHT CHANCE TO CHANCE POPS...MAINLY FAVORING SE GA FOR THE AFTERNOON/EVENING. WITH THE TIGHT PRESSURE GRADIENT ON THE EASTERN PERIPHERY OF THE SURFACE RIDGE...A BREEZY NE FLOW IS EXPECTED TO PREVAIL. CLOUD COVER THE NE FLOW WILL KEEP TEMPS DOWN JUST A BIT...WITH HIGHS RISING TO AROUND 80/LOW 80S AND LOWS FALLING INTO THE UPPER 50S NORTH...LOW 60S SOUTH. SATURDAY THROUGH SUNDAY...THERE WILL BE LITTLE CHANGE ALOFT AS THE UPPER LOW DRIFTS ABOUT THE SOUTHEAST COASTAL REGION. HIGH PRESSURE OVER THE MID ATLANTIC WILL REMAIN IN PLACE WITH LOW LEVEL RIDGING EXTENDING DOWN THE EAST SIDE OF THE APPALACHIANS. MODERATE NE FLOW WILL CONTINUE THROUGH THE DURATION OF THE WEEKEND AS THE MAIN FORECAST QUESTION REVOLVES AROUND PRECIP CHANCES. THE SUITE OF MODEL GUIDANCE HAS CONSISTENTLY SHOWN THE DEVELOPMENT OF AN OFFSHORE LOW THAT PASSES WELL OFF THE EAST COAST AND LIFTS NORTHWARD THROUGH THE WEEKEND. THE NAM/GFS FAVOR DRY CONDITIONS OVER THE FORECAST AREA THROUGH THE WEEKEND...WITH PRECIP JUST OFFSHORE ASSOCIATED WITH A BAND OF CONVERGENCE. THE ECMWF ON THE OTHER HAND HAS BEEN QUITE CONSISTENT SHOWING PRECIP MOVING ONSHORE AND COVERING THE AREA. I HAVE FAVORED THE DRY SOLUTIONS BY GOING WITH VERY LOW END POPS...BUT HAVE KEPT THINGS IN THE SLIGHT CHANCE RANGE AS A NOD TO THE ECMWF. TEMPS WILL BE VERY SIMILAR DAY TO DAY...JUST A FEW DEGREES BELOW CLIMO. && .LONG TERM /SUNDAY NIGHT THROUGH WEDNESDAY/... THE CLOSED UPPER LOW IS EXPECTED TO LINGER OVER THE REGION MONDAY AND INTO TUESDAY...BEFORE BEGINNING TO INTERACT WITH SHORTWAVE ENERGY MOVING ACROSS THE GREAT LAKES. AS IT DOES THE LOW WILL OPEN UP AND EVENTUALLY BECOME ABSORBED INTO THE APPROACHING TROF. THROUGH THE END OF THE PERIOD...GENERAL TROFFING WILL REMAIN IN PLACE AND BEGIN TO WEAKEN INTO MID WEEK. THE MID ATLANTIC SURFACE HIGH WILL WEAKEN THROUGH MONDAY AND A RATHER NEBULOUS PATTERN WILL PERSIST THEREAFTER AS A SLOW MOVING COLD FRONT APPROACHES FROM THE NORTHWEST. OTHER THAN SOME DIURNAL SHOWERS/STORMS...THE OVERALL PERIOD WILL BE QUIET. I HAVE GENERALLY KEPT POPS IN THE SLIGHT CHANCE RANGE THROUGH THE PERIOD. CONCERNING TEMPERATURES...THE PERIOD WILL START OFF NEAR NORMAL WITH A WARMING TREND THEREAFTER BACK TO ABOVE NORMAL. && .AVIATION /14Z THURSDAY THROUGH MONDAY/... BOTH TERMINALS VFR AT 11Z WITH 06Z SOUNDINGS INDICATING A CAP HAS DEVELOPED AT KCHS AFTER THE NOCTURNAL CONVECTION WHILE A WEAKER CAP NOTED ALONG AND W OF I-95 INCLUDING THE SAVANNAH AREA. THE PRESENCE OF THE UPPER LOW AND LOW LEVEL BOUNDARIES INCLUDING THE SEA BREEZE SHOULD INCREASE SHOWER AND TSTM COVERAGE THIS AFTERNOON BUT TIMING/INITIATION/COVERAGE REMAIN DIFFICULT ONCE AGAIN ALONG THE COASTAL CORRIDOR. THE CONCERN FOR TONIGHT IS DEVELOPMENT AND ADVECTION OF LOW CLOUDS AS SURFACE WINDS TURN NE. NUMERICAL GUIDANCE SUGGESTS MVFR/IFR CIGS COULD SPREAD INTO THE REGION TONIGHT AND WE HAVE TRENDED TOWARD THE LOWER CIGS WITH GRADUAL LOWERING CONDITIONS. EXTENDED AVIATION OUTLOOK...PERIODIC MVFR LEVEL CEILINGS WILL BE POSSIBLE THROUGH FRIDAY. BREEZY CONDITIONS EXPECTED THROUGH THE WEEKEND. && .MARINE... CONDITIONS WILL BEGIN TO DETERIORATE TONIGHT AS HIGH PRES TO THE N BUILDS A TIGHTER GRADIENT OVER THE WATERS. MARINE GUIDANCE IS STRONGEST ON THE NAM SIDE AND WEAKER WITH THE GFS. OVERALL WE SPLIT THE DIFFERENCE AND ALLOW WINDS TO INCREASE TO NEAR 15 KT WITH GUSTS NEARING 25 KT LATE. SEAS BUILDING TO 3 TO 5 FT FROM TODAY/S 2 TO 3 FT. FRIDAY THROUGH MONDAY...HIGH PRESSURE WILL BE POSITIONED OVER THE MID ATLANTIC WITH A TIGHT NORTHEAST PRESSURE GRADIENT IN PLACE OVER THE LOCAL WATERS ON FRIDAY. WINDS AND SEAS EXPECTED TO BE ELEVATED THROUGH THE DAY ON FRIDAY...AND SCA/S MAY POSSIBLY BE NEEDED FOR PORTIONS OF THE WATERS. RIGHT NOW IT APPEARS MOST LIKELY FOR THE CHARLESTON NEARSHORE WATERS AND PERHAPS THE CHARLESTON HARBOR. THE ELEVATED WINDS/SEAS AND NEAR SCA CONDITIONS WILL PERSIST INTO SATURDAY AS THE TIGHT PRESSURE GRADIENT CONTINUES THROUGH THE WEEKEND. THE SURFACE HIGH AND ASSOCIATED PINCHED GRADIENT WILL BEGIN TO WEAKEN EARLY NEXT WEEK. RIP CURRENTS...AN ELEVATED RISK OF RIP CURRENTS APPEARS LIKELY AT THE BEACHES FRIDAY THROUGH MONDAY...WITH A PERSISTENT MODERATE NORTHEAST/EAST WIND PREVAILING. && .CHS WATCHES/WARNINGS/ADVISORIES...
