The episode as NWS CHS wrote it up.
With a high amplitude long wave trough aloft, and with a cold front positioned to the north, scattered severe thunderstorms developed in the late morning and early afternoon hours.
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 Aug 19, 9:45 AM EST, 44 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 1045 AM EDT SUN AUG 19 2012 ...SEVERE THUNDERSTORM WATCH IN EFFECT UNTIL 6 PM FOR MUCH OF SOUTHEAST SOUTH CAROLINA AND SOUTHEAST GEORGIA... .SYNOPSIS... A WEAK COLD FRONT WILL LINGER JUST NORTH AND WEST OF THE AREA THROUGH TUESDAY...THEN MOVE OFFSHORE AND DISSIPATE BY WEDNESDAY AS A WEAK AREA OF HIGH PRESSURE BUILDS INTO THE NORTHEAST STATES. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... UPDATED ALL GRIDDED AND TEXT PRODUCTS TO HIGHLIGHT SEVERE TSTM WATCH NUMBER 585 UNTIL 6 PM. WIDESPREAD SHOWERS/TSTMS ASSOCIATED WITH THE TAIL END OF A SHORTWAVE MOVING THROUGH THE FOOTHILLS OF NORTH CAROLINA WILL GRADUALLY WORK SOUTHWEST-NORTHEAST THROUGH MUCH OF THE FORECAST AREA TODAY. A FAVORABLE UPPER FORCING PATTERN FEATURING WEAK DPVA AND UPPER DIFLUENCE COUPLED WITH HIGH PWATS AND WEAK-MODERATE INSTABILITY SUGGEST MANY AREAS WILL SEE MEASURABLE RAINFALL TODAY. MODELS ARE HANDING THE MOVEMENT AND POSITION OF THE CURRENT ACTIVITY VERY POORLY THIS MORNING WHICH DOES LEAD TO SOME UNCERTAINLY ON HOW THINGS WILL EVOLVE LATER THIS AFTERNOON. COMPLICATING MATTERS IS THE CONVECTION CURRENTLY LINING UP ALONG THE NORTHEAST GULF COAST. CURRENT RADAR TRENDS SUGGEST MUCH OF THIS ACTIVITY WILL REMAIN TO THE SOUTH AND EXPAND INTO NORTHERN FLORIDA AND FAR SOUTHEAST GEORGIA...WHICH MAY DISRUPT LOW-LEVEL MOISTURE ADVECTION NORTH OF THE ALTAMAHA RIVER LATER TODAY. SHOULD THIS OCCUR...RAIN CHANCES ACROSS THE CWFA MAY UNEXPECTEDLY DIMINISH RAPIDLY THIS AFTERNOON. HAVE MADE SOME FAIRLY SIZABLE ADJUSTMENTS TO HOURLY POPS WITH THE MORNING UPDATE...SHOWING POPS UP TO 90 PERCENT ACROSS THE FAR WEST...THEN EXPANDING CATEGORICAL POPS OF 80 PERCENT OR GREATER TO THE AREAS NORTH OF INTERSTATE 16...INCLUDING BEAUFORT AND THE CHARLESTON METRO AREA. OPTED TO KEEP HIGH-END LIKELY POPS FOR AREAS FARTHER SOUTH INCLUDING THE SAVANNAH METRO AREA. FURTHER REFINEMENTS WILL MOST CERTAINLY BE NEEDED AS THE DAY PROGRESSES AND MESOSCALE TRENDS BECOME MORE APPARENT. 0-6 KM BULK SHEAR OF 30-35 KT COUPLED WITH WEAK-MODERATE INSTABILITY MAY SUPPORT AN ISOLATED SEVERE TSTM JUST ABOUT ANYTIME TODAY. THE RISK WILL BE HEAVILY MODULATED BY THE CLOUD COVER THAT WILL BE IN PLACE...BUT THE RISK MAY BECOME LOCALLY ENHANCED WHERE POCKETS OF HIGHER INSTABILITY OCCURS. ATTM THIS LOOKS TO BE ALONG AND EAST OF I-95...INCLUDING THE SAVANNAH-BEAUFORT-WALTERBORO- CHARLESTON-MONCKS CORNER CORRIDOR. && .SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/... DEEP UPPER LEVEL TROUGHING WILL PERSIST TONIGHT...WHILE AT THE SURFACE A WAVE OF LOW PRESSURE WILL SHIFT OFF THE MID-ATLANTIC COAST CAUSING A COLD FRONT TO DROP TOWARD THE AREA FROM THE NORTH. THE PRESENCE OF THE FRONT...DEEP LAYERED MOISTURE AND SEVERAL PASSING SHORT WAVE DISTURBANCES WILL BE ENOUGH TO SUPPORT A CHANCE OF SHOWERS AND THUNDERSTORMS TONIGHT. LOWS WILL BE IN THE LOWER TO MID 70S WITH EXTENSIVE CLOUD COVER LIKELY TO PERSIST THROUGH THE NIGHT. MONDAY THROUGH TUESDAY...THE UPPER TROUGH WILL MAINTAIN CONTROL ACROSS THE EASTERN HALF OF THE UNITED STATES WHILE ITS ASSOCIATED COLD FRONT REMAINS IN THE VICINITY OF THE FORECAST AREA. SEVERAL FACTORS INDICATE PERIODS OF VERY WET CONDITIONS WILL PERSIST THROUGH THE PERIOD. MODELS HAVE BEEN CONSISTENTLY SHOWING PWATS AROUND 2 INCHES...IF NOT HIGHER...AS A PERSISTENT SOUTHWESTERLY FLOW ALLOWS PLENTY OF DEEP TROPICAL MOISTURE TO STREAM ACROSS THE SOUTHEAST. ALSO...THE UPPER JET WILL EXTEND FROM THE MISSISSIPPI VALLEY UP TO THE NEW ENGLAND AREA WITH THE 100+ KNOT JET JUST NORTHWEST OF THE AREA. THIS WILL PROVIDE DECENT LIFT AND AMPLE AMOUNTS OF UPPER LEVEL DIVERGENCE. CAN NOT RULE OUT AN ISOLATED STRONG TO SEVERE STORM....BUT WITH SHOWALTER INDICES GENERALLY POSITIVE AND LIFTED INDICES AROUND -3C...THE SEVERE THREAT APPEARS LOW. ALSO...PLENTY OF CLOUD COVERAGE WILL AID IN KEEPING MAX TEMPERATURES A FEW DEGREES BELOW SEASONAL NORMALS WHICH WILL ALSO HINDER THE SEVERE POTENTIAL. TEMPERATURES WILL TOP OUT IN THE MID TO UPPER 80S BOTH AFTERNOONS WITH LOW TEMPERATURES DIPPING INTO THE UPPER 60S FAR INLAND AND LOW 70S CLOSER TO THE COAST. TUESDAY NIGHT THROUGH WEDNESDAY...HEIGHTS WILL SLOWLY BEGIN TO RISE AS THE UPPER TROUGH STARTS TO WEAKEN. AS THE SURFACE...THE COLD FRONT WILL PUSH OFFSHORE PRIOR TO DISSIPATING ON WEDNESDAY. MODELS SHOW A WEAK SHORT WAVE SWINGING ALONG THE WEAKENING TROUGH AXIS... LIKELY PASSING JUST NORTH OF THE AREA. PWATS WILL TREND DOWNWARD ON WEDNESDAY...BUT WITH PASSING SHORT WAVE ENERGY...WILL MAINTAIN CHANCE POPS EVERYWHERE WITH THE HIGHEST POTENTIAL ALONG COASTAL COUNTIES AND THE NEIGHBORING WATERS. THIS IS WHERE BETTER SURFACE CONVERGENCE WILL EXIST. HIGH TEMPERATURES WILL ONCE AGAIN TOP OUT IN THE MID TO UPPER 80S. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... THE WEAKENING UPPER TROUGH WILL STRUGGLE IN MAINTAINING ITS HOLD OVER THE EASTERN HALF OF THE UNITED STATES THROUGH THE EXTEND PERIOD. HEIGHTS WILL CONTINUE TO RISE AS THE UPPER RIDGE OVER CENTRAL UNITED STATES PUSHES EASTWARD. AS THE SURFACE...HIGH PRESSURE WILL BUILD OVER THE REGION BY LATE WEEK. THIS PATTERN WILL BE MUCH LESS PRODUCTIVE AT PRODUCING PRECIPITATION...BUT WITH A PREVAILING ONSHORE FLOW...EXPECT PERIODS OF ISOLATED TO SCATTERED CONVECTION TO DEVELOP...MAINLY DURING THE TRADITIONAL LATE AFTERNOON/EARLY EVENING HOURS. TEMPERATURES WILL REMAIN NEAR SEASONAL NORMALS...IF NOT THEN SLIGHTLY BELOW. OVERALL...EXPECT HIGH TEMPERATURES IN THE MID TO UPPER 80S AND LOW TEMPERATURES IN THE MID TO UPPER 60S INLAND AND LOW 70S CLOSER TO THE COAST. && .AVIATION /15Z SUNDAY THROUGH THURSDAY/... DRY CONDITIONS WITH VFR CEILINGS/VISIBILITIES ARE EXPECTED TO PREVAIL AT KCHS AND KSAV THROUGH MID-MORNING. THEN...SHOWERS AND THUNDERSTORMS WILL DEVELOP AS AN UPPER LEVEL DISTURBANCE INTERACTS WITH A VERY MOIST AND UNSTABLE AIRMASS. THE POTENTIAL FOR CONVECTION AT THE TERMINALS APPEARS BEST FROM LATE MORNING INTO THE EARLY EVENING AND HAVE INCLUDED VICINITY THUNDERSTORMS AND A CB GROUP DURING THIS TIME PERIOD. A TEMPO GROUP FOR THUNDERSTORMS HAS ALSO BEEN INCLUDED AT KCHS FROM 15-18Z WHEN UPSTREAM CONVECTION IS TIMED TO MOVE ACROSS THE TERMINAL. REDUCTIONS IN CEILINGS/VISIBILITIES TO SUB-VFR LEVELS WILL BE POSSIBLE WITH ANY THUNDERSTORMS THAT IMPACT THE TERMINALS. THERE IS SOME SUGGESTION WITH THE LATEST GUIDANCE THAT MVFR OR LOWER CEILINGS ARE POSSIBLE LATE TONIGHT ONCE CONVECTION TAPERS OFF. EXTENDED AVIATION OUTLOOK...MVFR CEILINGS WILL BE POSSIBLE DURING THE EARLY MORNING HOURS MONDAY AND TUESDAY AS PLENTY OF MOISTURE RESIDES ACROSS THE AREA. OTHERWISE...SCATTERED CONVECTION MAY BRING VSBYS DOWN TO MVFR/IFR FOR SHORT PERIODS OF TIME EACH AFTERNOON AND EVENING. && .MARINE... A FRONT WILL REMAIN NEARLY STATIONARY NORTHWEST OF THE AREA TODAY THROUGH TONIGHT...KEEPING A SYNOPTIC SOUTHWEST FLOW IN PLACE. A WAVE OF LOW PRESSURE TRACKING ALONG THE FRONT WILL CAUSE LOW LEVEL WINDS TO INCREASE THIS AFTERNOON INTO THIS EVENING...AND AS A RESULT WINDS AT THE SURFACE COULD INCREASE UPWARDS OF 15-20 KT AT TIMES...HIGHEST OVER THE SOUTH CAROLINA NEAR SHORE WATERS AND OUTER GEORGIA WATERS. SEAS WILL GENERALLY REMAIN 2-3 FT THROUGH TONIGHT. A COLD FRONT WILL APPROACH THE MARINE AREA THROUGH EARLY NEXT WEEK PRIOR TO DISSIPATING BY WEDNESDAY. OVERALL...EXPECT CONDITIONS TO REMAIN BELOW SMALL CRAFT CRITERIA...BUT AS THE FRONT NEARS...THE TIGHTENING PRESSURE GRADIENT WILL LIKELY RESULT IN BRIEF SURGES OF ELEVATED WINDS AND SEAS. GENERALLY...EXPECT WINDS TO BE NO MORE THAN 15 TO 20 KNOTS AND SEAS NO HIGHER THAN 3 TO 4 FEET THROUGH TUESDAY. THEREAFTER...MORE TRANQUIL CONDITIONS WILL PERSIST AS HIGH PRESSURE DEVELOPS INLAND. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. && SYNOPSIS... NEAR TERM...
