The episode as NWS CHS wrote it up.
A pulse thunderstorm environment was in place during the evening hours over southeast Georgia. A few thunderstorms became strong along boundary interactions and cell mergers as they slowly shifted over Liberty County.
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 21, 5:04 PM EST, 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 604 PM EDT SUN AUG 21 2011 .SYNOPSIS... HIGH PRESSURE WILL GIVE WAY TO A COLD FRONT FROM THE NW LATE MONDAY. THE FRONT WILL STALL OVER OR NEAR THE AREA TUESDAY...THEN DISSIPATE WEDNESDAY AS HIGH PRESSURE BUILDS FROM THE NORTH. TROPICAL CYCLONE IRENE MAY HAVE AN IMPACT ON THE AREA LATE IN THE WEEK. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... ADJUSTED EVENING POPS BASED ON RECENT RADAR TRENDS...WITH MOST NUMEROUS THUNDERSTORMS ACROSS SE GA S OF I-16...TAPERED TO SLIGHT CHANCE POPS FARTHER N/W. BOUNDARY INTERACTIONS AND CELL MERGERS WILL SUPPORT A LOW END THREAT FOR PULSE SEVERE THUNDERSTORMS WITH DAMAGING MICROBURSTS MAINLY S OF I-16 UNTIL AFTER SUNSET. CONVECTION SHOULD CONTINUE THROUGH THE EVENING SUPPORTED BY A DECENT STRENGTH SHORTWAVE FOR AUGUST PASSING BY TO THE NORTH AND ONGOING BOUNDARY INTERACTIONS. THEN...DAYTIME HEATING ENDS AND INSTABILITY DECREASES DRAMATICALLY. WIDELY SCATTERED ACTIVITY WILL PERSIST UNTIL MIDNIGHT OR SHORTLY AFTER DUE TO THE UPPER LEVEL SUPPORT...BUT MOST OF IT SHOULD WIND DOWN AFTER 2 AM. THE EXCEPTION MAY BE RIGHT ALONG THE BEACHES OF SOUTH CAROLINA AS THE LAND BREEZE CONVERGENCE LINE WILL BE JUST OFFSHORE NEAR SUNRISE. LOW TEMPS SHOULD BE SEASONABLY MILD IN THE 70S...LOWER AS ONE MOVES INLAND. && .SHORT TERM /6 AM MONDAY MORNING THROUGH WEDNESDAY/... MONDAY...THE PERSISTENT MID AND UPPER TROUGH OVER THE EASTERN SEABOARD BEGINS TO PUSH EAST INTO THE ATLANTIC...AS THE ANTICYCLONE ALOFT REMAINS ANCHORED OVER THE SOUTHERN PLAINS...STRETCHING EAST-SE TO FLORIDA. ONE SHORT WAVE EMBEDDED WITHIN THE WEST-NW FLOW ALOFT OVER OUR AREA SHIFTS EAST INTO THE ATLANTIC DURING THE EARLY MORNING...WITH NVA TO FOLLOW FOR MUCH OF THE DAY. HOWEVER...ANOTHER WEAK SHORT WAVE WILL MOVE IN LATE IN THE DAY AND PUSHES THROUGH EARLY MONDAY NIGHT. AT THE SAME TIME A COLD FRONT WILL SHIFT TOWARD THE AREA FROM THE NW DURING THE AFTERNOON/EVENING...AND THE SET UP IS IN PLACE FOR SOME STRONG TO SEVERE THUNDERSTORMS TO DEVELOP AND/OR ADVECT IN. FORCING WILL BE ENHANCED DURING THE MID/LATE AFTERNOON INTO THE EVENING AS AN UPPER LEVEL JET PUSHES IN FROM THE OH/TN VALLEYS...RESULTING IN SOME DECENT DIVERGENCE ALOFT. PLUS THERE IS SUFFICIENT LOW LEVEL FORCING FROM NOT ONLY THE SEA BREEZE...BUT ALSO THE NEARBY FRONT AND VARIOUS OUTFLOWS THAT FORM AS CONVECTION GETS GOING. OUR CONVECTIVE TEMPS ARE IN THE LOWER 90S...SO LOOK FOR AN EARLY AFTERNOON START TO ACTIVITY...WHICH WILL ONLY INCREASE IN COVERAGE AS POSSIBLE CONSOLIDATION OF CONVECTION DEVELOPS UPSTREAM WITHIN THE WEST-NW FLOW ALOFT. ALTHOUGH OUR MID LEVEL LAPSE RATES ARE WEAK...LOW LEVEL LAPSE RATES ARE QUITE IMPRESSIVE AND MANY THERMODYNAMIC PARAMETERS ARE QUITE FAVORABLE. FOR INSTANCE...SBCAPES ARE AS HIGH AS 2500-3500 J/KG...MUCAPES ARE OVER 4000 J/KG...LIFTED INDICES ARE AS LOW AS -6/-7. WITH 0-6 KM BULK SHEAR AS MUCH AS 25-30 KT THERE COULD BE SOME CLUSTERS OF STORMS THAT ALSO DEVELOP...ESPECIALLY AS INTERACTIONS OF BOUNDARIES TAKES PLACE. THE MAIN WEATHER HAZARD WOULD BE DAMAGING DOWNBURSTS OF WIND WITH DCAPES AS MUCH AS 1200-1400 J/KG...GIVEN THE DRY AIR ABOUT 12K FEET. CONFIDENCE/PROBABILITIES ARE HIGH ENOUGH TO ADD TO THE HAZARDOUS WEATHER OUTLOOK...ALTHOUGH AN ORGANIZED SEVERE WEATHER EVENT IS NOT EXPECTED AT THIS TIME. WE/LL SHOW COVERAGE INCREASING TO THE 40-50 PERCENT RANGE DURING THE MID/LATE AFTERNOON...WITH CONVECTION TO LIKELY CONTINUE THROUGH LATE EVENING GIVEN SUPPORT FROM DYNAMICS ALOFT AND FURTHER AIDED BY A 20-25 KT LOW LEVEL JET THAT SCRAPS THE AREA TO THE SOUTH. COMPRESSIONAL HEATING AHEAD OF THE FRONT AND 850 MB TEMPS THAT ARE 19-20C WILL SUPPORT MAX TEMPS MONDAY IN THE LOWER AND MIDDLE 90S AWAY FROM THE BEACHES. HOURLY GRIDS WILL NEED TO BE ADJUSTED AT A LATER TIME AS RAIN-COOLED AIR DEVELOPS...BUT THAT WILL HELP IN DROPPING MIN TEMPS MONDAY NIGHT DOWN INTO THE LOWER AND MIDDLE 70S. TUESDAY...THE TROUGH ALOFT REMAINS JUST OFFSHORE...BUT SOLID NVA PREVAILS THROUGH MUCH OF THE DAY AS A SHORT WAVE EXITS THE AREA BEFORE DAYBREAK. THE COLD FRONT MEANWHILE SAGS INTO THE CENTRAL OR SOUTHERN CWFA...WITH QUITE A BIT OF DRIER AIR TO MOVE IN FROM THE NORTH BEHIND THE FRONT. HOWEVER...THERMODYNAMIC PROFILE AND SUFFICIENT LOW LEVEL MOISTURE POINTS TO 20-30 POPS...HIGHEST SOUTH OF I-16 IN SE GA WHERE INTERACTION OF SEA BREEZE WILL COME INTO PLAY. 850 MB TEMPS DROP DOWN TO 17-18C...AND WITH AN EAST TO NE SYNOPTIC FLOW DEVELOPING IN WAKE OF THE FRONT WE ARE LOOKING AT LOWER TEMPS. UPPER 80S TO AROUND 90 NORTH...BUT STILL SOME LOWER AND PERHAPS MID 90S SOUTH. WEDNESDAY...THIS APPEARS TO BE A PIVOTAL DAY IN REGARDS TO IRENE...AS A SHORT WAVE NOW IN THE CANADIAN ROCKIES LOOKS TO DROP INTO THE TROUGH OVER OR NEAR THE EAST COAST. IF THIS WERE TO OCCUR IT MIGHT KEEP THE TROUGH IN THE AREA LONGER...WHICH IN TURN COULD PULL IRENE MORE NORTH AND QUICKER. MANY OF THE MODEL GUIDANCE IS SUPPORTIVE OF THIS IDEA WITH SOME INDICATIONS THAT IRENE COULD STAY OVER THE ATLANTIC. THIS MAY BE OPTIMISTIC...BUT IS CERTAINLY A POSSIBILITY. BUT IT IS ONLY ONE MODEL RUN...SO YOU ARE STRONGLY ADVISED TO REFER TO THE NATIONAL HURRICANE CENTER FOR THE LATEST INFORMATION ON IRENE. FOR OUR AREA WEDNESDAY...THE COLD FRONT WASHES OUT AN LOW LEVEL MOISTURE AND CONVERGENCE FROM THE ATLANTIC SHOULD EB ENOUGH TO SUPPORT 20-30 POPS. MAX TEMPS WILL BE HELD DOWN WITH THE ONSHORE SYNOPTIC FLOW...UPPER 80S NORTH AND LOWER 90S SOUTH. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... MUCH OF THE EXTENDED FORECAST WILL BE HIGHLY DEPENDENT ON THE DEVELOPMENT AND PROGRESSION OF TROPICAL CYCLONE IRENE. ALTHOUGH NUMERICAL MODELS HAVE BEEN FAIRLY CONSISTENT IN TRACKING THE SYSTEM TOWARD THE FLORIDA AND/OR SOUTHEAST COAST...THERE REMAINS CONSIDERABLE UNCERTAINTY REGARDING THE EVOLUTION OF THIS SYSTEM. THUS WE PREFER TO REMAIN RATHER GENERIC REGARDING PRECIPITATION POTENTIAL AND HAVE INDICATED SOLID RAIN CHANCES IN THE 30 TO 40 PERCENT RANGE THROUGH THE LATE WEEK AND WEEKEND PERIOD. WILL FORECAST HIGH TEMPERATURES RIGHT AROUND SEASONAL NORMALS IN THE UPPER 80S TO LOWER 90S. IT IS RECOMMENDED THAT ALL RESIDENTS AND VISITORS OF SOUTHEAST SOUTH CAROLINA AND SOUTHEAST GEORGIA CONTINUE TO MONITOR FORECASTS FROM THE NATIONAL HURRICANE CENTER REGARDING TROPICAL CYCLONE IRENE. && .AVIATION /22Z SUNDAY THROUGH FRIDAY/... THUNDERSTORMS WILL EXIT THE SAV VICINITY BY 00Z. SHOWERS/THUNDERSTORMS COULD DEVELOP CLOSE TO KCHS LATE TONIGHT/EARLY MONDAY MORNING. OTHERWISE...VFR FORECAST THROUGH TONIGHT. EXTENDED AVIATION OUTLOOK...SHOWERS AND THUNDERSTORMS COULD BRIEFLY REDUCE VSBYS AND/OR CIGS EACH AFTERNOON/EVENING THIS WEEK. BREEZY CONDITIONS ARE POSSIBLE LATER IN THE WEEK CONSIDERING POTENTIAL IMPACTS FROM TROPICAL CYCLONE IRENE. && .MARINE... A TIGHTENING SURFACE PRESSURE GRADIENT/INTENSIFYING LOW LEVEL WINDS AHEAD OF AN APPROACHING COLD FRONT WILL SUPPORT S WINDS 15-20 KT TONIGHT. SEAS WILL AVERAGE 2-4 FT...POSSIBLE AS HIGH AS 5 FT BEYOND 20 NM. MONDAY WILL BE THE LAST DAY WITH SOUTH AND SW WINDS FOR AWHILE...AS THE SUB TROPICAL ATLANTIC RIDGE GIVES WAY TO A COLD FRONT FROM THE NW. LINGERING NOCTURNAL SURGE WILL BE WANING EARLY MONDAY...SO SPEEDS WILL GENERALLY DROP TO 15 KT OR LESS BY MID MORNING. SEAS WILL BE A MIX OF SMALL SWELLS AND SMALL WIND WAVES...BUT NO MORE THAN 3 OR 4 FT. WINDS WILL STEADILY SHIFT AROUND TO THE NE AND EAST AS THE COLD FRONT DROPS INTO THE AREA MONDAY NIGHT/TUESDAY...AND THERE ARE SOME INDICATIONS THAT AS HIGH PRESSURE BUILDS TO THE NORTH THERE COULD BE SOME MODEST PINCHING OVER THE AMZ350 WATERS. EVEN SO...CONDITIONS DO LOOK TO REMAIN BELOW ANY SCA CRITERIA THROUGH TUESDAY. THE FRONT WILL DISSIPATE WEDNESDAY AS HIGH PRESSURE TO THE NORTH TEMPORARILY SPREADS ACROSS THE WATERS. THIS KEEPS AN EASTERLY FLOW IN PLACE AT LESS THAN 15 KT...ALTHOUGH SEAS MAY SLOWLY BEGIN TO BUILD WITH THE LONG DURATION ONSHORE FETCH. FOR LATE IN THE WEEK THERE ARE POTENTIAL IMPACTS FROM IRENE...BUT THERE IS TOO MUCH UNCERTAINTY REGARDING HER STRENGTH AND HER TRACK WE HAVE OPTED TO CAP WINDS AT 25 OR 30 KT AND SEAS NO MORE THAN 6-8 FEET. BUT THIS COULD CHANGE CONSIDERABLY IN LATER FORECASTS. MARINERS ARE ADVISED THAT SCA/S...GALES OR EVEN TROPICAL HEADLINES COULD BE REQUIRED LATER IN THE WEEK. ALL MARINERS ARE THUS STRONGLY ADVISED TO CONTINUE TO MONITOR THE PROGRESS OF IRENE FROM ADVISORIES ISSUED BY NHC. MARINERS ARE ALSO ADVISED THAT WITH A WESTERLY STEERING FLOW THERE COULD BE SOME STRONG TO SEVERE STORMS THAT IMPACT THE MARINE AREA FROM OFF THE LAND AREAS LATE MONDAY INTO MONDAY NIGHT. DAMAGING WINDS AND FREQUENT LIGHTNING STRIKES ARE POSSIBLE. && .TIDES/COASTAL FLOODING... ASTRONOMICAL HIGH TIDES WILL DEVELOP ACROSS THE AREA LATE THIS WEEK...AND DEPENDENT UPON WHAT IF ANY IMPACTS WE RECEIVE FROM IRENE THERE MAY BE SOME COASTAL FLOODING AND BEACH EROSION CONCERNS BEGINNING FRIDAY. RIP CURRENTS...SWELLS FROM IRENE COULD ARRIVE AS EARLY AS MID-WEEK...AND CONTINUE FOR SEVERAL DAYS. THIS WILL RESULT IN AN ENHANCED RISK OF RIP CURRENTS. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
