The episode as NWS CHS wrote it up.
A trough of low pressure extended from northern Florida to the coastal waters along the Georgia coast. Sufficient uplift was created for shower and thunderstorm development as the trough of low pressure slowly shifted east towards the Georgia coast. A few thunderstorms became strong during peak heating hours as a seabreeze developed and moved inland along the Georgia coast.
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 23, 3:15 PM EST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON SC 415 PM EDT TUE AUG 23 2011 .SYNOPSIS... A COASTAL TROUGH WILL LINGER ALONG THE COAST THROUGH THURSDAY. HURRICANE IRENE COULD IMPACT THE AREA LATE FRIDAY INTO THE WEEKEND. HIGH PRESSURE IS THEN EXPECTED TO BUILD BACK INTO THE AREA EARLY NEXT WEEK. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... CURRENTLY AT THE SURFACE...HIGH PRESSURE IS CENTERED OVER THE MID- ATLANTIC STATES WITH A TROUGH OF LOW PRESSURE EXTENDING FROM NORTHERN FLORIDA OFF TO THE NORTHEAST INTO THE ATLANTIC WELL OFF THE GEORGIA AND SOUTH CAROLINA COAST. MEANWHILE...HURRICANE IRENE IS LOCATED WELL TO THE SOUTHEAST OF THE LOCAL AREA...JUST NORTH OF HAITI LATE THIS AFTERNOON. RADAR IMAGERY SHOWS GENERALLY SCATTERED SHOWER/THUNDERSTORM COVERAGE ACROSS THE AREA...WITH VISIBLE SATELLITE IMAGERY SHOWING PARTLY TO MOSTLY CLOUDY CONDITIONS IN PLACE. MAIN NEAR TERM CONCERN REVOLVES AROUND POPS. HIGH PRESSURE NORTH OF THE REGION WILL BUILD EASTWARD AND INTO THE WESTERN ATLANTIC OVERNIGHT...ALLOWING THE TROUGH OF LOW PRESSURE WELL OFF THE CAROLINA AND GEORGIA COAST TO SHIFT SLOWLY BACK TOWARD SHORE. EXPECT THAT CONVECTION LATE THIS AFTERNOON WILL PROGRESS STEADILY INLAND WITH THE SEA BREEZE...AND WILL KEEP POPS IN THE SLIGHT CHANCE/LOW CHANCE RANGE MOST LOCALES THROUGH EARLY THIS EVENING. AFTER MIDNIGHT...EXPECT THAT INTERIOR LOCALES WILL CLEAR OUT WITH RAIN FREE CONDITIONS PREVAILING. CLOSER TO THE COAST HOWEVER...WIND SPEED AND DIRECTIONAL CONVERGENCE MAY ALLOW FOR SOME ISOLATED SHOWERS TO ROLL IN OFF THE ATLANTIC...SO WILL KEEP SLIGHT CHANCE/LOW CHANCE POPS GOING IN THESE LOCALES. OVERNIGHT LOWS ARE EXPECTED TO BOTTOM OUT IN THE UPPER 60S WELL INLAND AND IN THE LOWER 70S CLOSER TO THE COAST. && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/... WEDNESDAY...CHANCES OF SHOWERS/THUNDERSTORMS WILL REMAIN IN THE FORECAST WEDNESDAY AS SFC HIGH PRESSURE SLIDES OFF THE MID ATLANTIC COAST AND A COASTAL TROUGH PERSISTS ALONG THE SOUTHEAST SOUTH CAROLINA AND GEORGIA COASTLINE. PRECIP CHANCES APPEAR BEST OVER COASTAL COUNTIES DURING EARLY AFTERNOON THROUGH EARLY EVENING HOURS. THE COASTAL TROUGH WILL THEN MAKE A GRADUAL SHIFT INLAND AND BEGIN TO WEAKEN AS HURRICANE IRENE MAKES A NORTHWARD MOVE TOWARDS THE SOUTHEASTERN UNITED STATES. HIGH TEMPS WILL BE LIMITED TO THE UPPER 80S OVER MOST AREAS...ESPECIALLY WITH CLOUD COVER INCREASING ALONG THE COASTAL TROUGH. A FEW LOCATIONS MAY TOUCH 90 DEGREES OVER INLAND PORTIONS AWAY FROM THE COASTAL TROUGH. SHOWERS AND THUNDERSTORMS MAY CONTINUE THROUGH WEDNESDAY NIGHT...BUT OVERALL COVERAGE WILL BE LESS WITH THE COASTAL TROUGH WEAKENING. OVERNIGHT LOWS WILL BE IN THE LOW/MID 70S. THURSDAY...UNCERTAINTY REMAINS IN THE FORECAST THURSDAY WITH THE APPROACH OF HURRICANE IRENE FROM THE SOUTH/SOUTHEAST AND A WEAK SFC TROUGH FROM THE NORTHWEST. CURRENT MODEL GUIDANCE AND NHC FORECASTS KEEP HURRICANE IRENE SOUTH OF THE AREA THROUGH THURSDAY NIGHT...BUT SIGNIFICANT MOISTURE ADVECTION AND PINCHING OF THE GRADIENT NORTH OF THE STORM MAY AID IN AFTERNOON CONVECTION ALONG A LINGERING COASTAL TROUGH. HAVE MAINTAINED CHANCES OF SHOWERS AND THUNDERSTORMS FOR ALL AREAS THROUGH THURSDAY EVENING AS A RESULT. A SLIGHT CHANCE TO CHANCE OF SHOWERS/THUNDERSTORMS ARE POSSIBLE THURSDAY NIGHT AS MOISTURE CONTINUES TO ADVECT ONSHORE WHILE THE WEAK SFC TROUGH APPROACHES FROM THE NORTHWEST. OVERALL...HIGH TEMPS WILL AGAIN BE LIMITED TO THE UPPER 80S FOR MOST AREAS DUE TO CLOUD COVER. A FEW LOCATIONS MAY REACH 90 WELL INLAND. OVERNIGHT LOWS WILL BE IN THE LOW/MID 70S. FRIDAY...THE LATEST NHC FORECAST HAS THE CENTER OF HURRICANE IRENE MAKING A NORTHWARD SHIFT THROUGH A WEAKNESS IN THE ATLANTIC RIDGE...BUT REMAINING OFF THE SOUTH CAROLINA AND GEORGIA COAST THROUGH FRIDAY AS AN H5 SHORTWAVE REACHES THE SOUTHEAST COAST FROM THE NORTHWEST. STRONG NORTHERLY WINDS ALONG THE WESTERN PORTION OF THE HURRICANE COULD DEVELOP ACROSS THE FORECAST AREA AT THIS TIME...CREATING BREEZY TO WINDY CONDITIONS OVER LAND. PRECIPITATION POTENTIAL WILL DEPEND HEAVILY ON THE TRACK AND SIZE OF THE TROPICAL SYSTEM. IF THE FORECAST AREA REMAINS ON THE WESTERN SIDE OF THE STORM...WHICH AT THIS TIME APPEARS TO BE THE CASE...RAINFALL POTENTIAL MAY BE GREATLY REDUCED. HOWEVER...A SLIGHT WESTWARD DEVIATION IN THE TRACK COULD RESULT IN SIGNIFICANTLY HIGHER IMPACTS FROM WINDS AND RAIN ON FRIDAY...ESPECIALLY DURING LATE AFTERNOON AND EVENING HOURS. HAVE MAINTAINED LIKELY POPS OVER THE COASTAL WATERS FOR THE TIME BEING...WITH 40/50 POPS OVER LAND. HIGH TEMPS WILL BE A FEW DEGREES COOLER THAN PREVIOUS DAYS AS CLOUD COVER EXPANDS OVER THE REGION WITH THE APPROACH OF HURRICANE IRENE. EXPECT OVERALL TEMPS TO BE LIMITED TO THE MID/UPPER 80S. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... IF CURRENT TRACK FORECAST VERIFIES...HURRICANE IRENE WILL BE CLOSELY APPROACHING THE SOUTH CAROLINA COASTLINE FRIDAY NIGHT...THEN STEADILY SHIFT NORTHWARD TOWARD THE NORTH CAROLINA COAST BY SATURDAY. AS MENTIONED BEFORE...EVEN A SLIGHT DEVIATION IN THE TRACK FORECAST COULD RESULT IN LARGE DIFFERENCES IN THE IMPACTS FOR THE FORECAST AREA. SINCE THIS SCENARIO IS 4-5 DAYS OUT...WOULD RATHER NOT FOCUS TOO MUCH ON DETAILS...WHICH ARE LIKELY TO CHANGE AS THE EVENT NEARS. SATURDAY...WINDY CONDITIONS ARE EXPECTED TO PERSIST INTO SATURDAY...ESPECIALLY ACROSS SOUTH CAROLINA COUNTIES NEAREST TO THE TROPICAL SYSTEM. WILL CONTINUE TO INDICATE FAIRLY HIGH POPS FOR THE EXTENDED PERIOD...RANGING FROM 40 TO 60 PERCENT ACROSS THE AREA. RAIN POTENTIAL WILL BE GRADUALLY SHIFTING NORTH WITH THE PROGRESSION OF THE STORM. DAYTIME TEMPERATURES WILL BE A BIT SUPPRESSED UNDER THICK CLOUD COVER...STRONG ONSHORE WINDS...AND DECENT RAIN COVERAGE. HIGH TEMPERATURES WILL LIKELY REACH THE MID TO UPPER 80S. SUNDAY THROUGH TUESDAY...WEATHER CONDITIONS ARE EXPECTED TO GRADUALLY IMPROVE INTO EARLY NEXT WEEK AS THE TROPICAL SYSTEM WILL BE MOVING AWAY FROM THE REGION TO THE NORTH. 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 HURRICANE IRENE. && .AVIATION /20Z TUESDAY THROUGH SUNDAY/... CAN/T RULE OUT AN ISOLATED SHOWER/STORM BRIEFLY REDUCING CIGS AND/OR VSBYS THIS EVENING AT THE SAV TERMINAL...SO WILL KEEP CB MENTIONED THROUGH 23Z. OTHERWISE...EXPECT VFR CONDITIONS THROUGH THE NIGHT. WITH AN EARLY SEA BREEZE PUSH WEDNESDAY...COULD SEE SOME SHOWER AND MVFR CIG DEVELOPMENT AT EITHER TERMINAL BETWEEN 15Z AND 18Z. EXTENDED AVIATION OUTLOOK...SHOWERS/THUNDERSTORMS COULD BRIEFLY REDUCE VSBYS AND/OR CIGS EACH AFTERNOON/EVENING THROUGH THURSDAY. TROPICAL STORM OR EVEN HURRICANE CONDITIONS ARE POSSIBLE FRIDAY AND SATURDAY AS HURRICANE IRENE POTENTIALLY IMPACTS THE REGION. && .MARINE... HIGH PRESSURE WILL BUILD NORTH OF THE WATERS TONIGHT...WHILE A TROUGH OF LOW PRESSURE LINGERS WELL OFFSHORE. EXPECT A BIT OF A SURGE IN THE WINDS THIS EVENING...BUT CONDITIONS ARE EXPECTED TO REMAIN WELL BELOW SMALL CRAFT THRESHOLDS. A COASTAL TROUGH WILL LIKELY PERSIST ALONG THE SOUTH CAROLINA AND GEORGIA COAST WEDNESDAY BEFORE WEAKENING THURSDAY. THIS PATTERN WILL LIKELY MAINTAIN SOLID ONSHORE FLOW AND INCREASE THE POTENTIAL FOR SCA LEVEL SEAS IN THE OUTER WATERS BY LATE WEDNESDAY. SCA TIMING WILL BE HIGHLY DEPENDENT ON THE LOCATION OF HURRICANE IRENE AS IT MAKES A NORTHWARD MOVE TOWARDS THE COASTAL WATERS...BUT SOLID SCA/S ARE LIKELY BY THURSDAY AFTERNOON BASED ON THE CURRENT NHC FORECAST TRACK. SHOWERS AND THUNDERSTORMS WILL ALSO BE POSSIBLE WHILE THE COASTAL TROUGH LINGERS THROUGH THURSDAY EVENING. HURRICANE IRENE STILL POSES A CONSIDERABLE THREAT TO THE COASTAL WATERS FRIDAY INTO THE WEEKEND...ALTHOUGH THERE CONTINUES TO BE SIGNIFICANT UNCERTAINTY IN THE TRACK FORECAST THIS FAR OUT. LATEST NATIONAL HURRICANE CENTER TRACK SUGGESTS TROPICAL STORM AND/OR HURRICANE CONDITIONS WILL BE POSSIBLE FRIDAY NIGHT AND SATURDAY...WITH WINDS POTENTIALLY UP TO 65 KT IN THE NORTHERN WATERS AND SEAS APPROACHING 17 TO 20 FT. MARINERS ARE ADVISED THAT TROPICAL CYCLONE WATCHES AND/OR WARNINGS COULD BE REQUIRED WITH LATER FORECAST ISSUANCES AND COULD CONTINUE THROUGH THE WEEKEND. ALL MARINERS ARE THUS STRONGLY ADVISED TO CONTINUE TO MONITOR THE PROGRESS OF IRENE FROM ADVISORIES ISSUED BY NATIONAL HURRICANE CENTER. RIP CURRENTS...SWELLS FROM IRENE COULD ARRIVE AS EARLY AS THURSDAY EVENING...AND CONTINUE FOR SEVERAL DAYS. THIS WILL RESULT IN AN ENHANCED RISK OF RIP CURRENTS. && .TIDES/COASTAL FLOODING... ASTRONOMICAL HIGH TIDES WILL DEVELOP ACROSS THE AREA LATE THIS WEEK...AND DEPENDENT UPON ANY IMPACTS FROM IRENE...THERE COULD BE SOME COASTAL FLOODING AND BEACH EROSION CONCERNS BEGINNING FRIDAY. && .CHS WATCHES/WARNINGS/ADVISORIES... GA...NONE. SC...NONE. MARINE...NONE. &&
