Deaths and injuries are direct and indirect together, as the offices filed them. Damage is property and crops in the dollars of the year, not adjusted for inflation, and only where an office estimated it.
The episode as NWS FFC wrote it up.
A deep upper low continued to meander about the central Appalachians and the mid-Atlantic region. A series of weak disturbances continued to rotate around the upper low across the southeast U.S. While across most of north and central Georgia, the atmosphere had become too cool and stable to support much thunderstorm activity, more unstable, moist air remained present across the far southeast part of the county warning area. This supported afternoon and evening thunderstorm development once again. A few of these thunderstorms became strong and produced penny to nickel-sized hail, but none of the thunderstorms reached severe limits.
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 Atlanta, GA wrote its last area forecast discussion before the first event at Sep 25, 12:45 PM EST, 21 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 145 PM EDT SUN SEP 25 2011 .PREV DISCUSSION... /ISSUED 1032 AM EDT SUN SEP 25 2011/ UPDATE... BASED ON RUC AND CURRENT TRENDS OF THE MOISTURE BOUNDARY MOVING WESTWARD AS WELL AS MODIFYING FFC SOUNDING FOR THE INCREASE IN MOISTURE...WILL INCREASE POPS OVER PARTS OF NORTH AND CENTRAL GEORGIA FOR THIS AFTERNOON. 17 PREV DISCUSSION... /ISSUED 258 AM EDT SUN SEP 25 2011/ SHORT TERM /TODAY THROUGH TUESDAY/... STALLED FRONTAL BOUNDARY REMAINS BETWEEN MACON AND DUBLIN...EXTENDING SOUTH SOUTHEAST FROM THERE THROUGH ALBANY. STARK CONTRAST IN DEWPOINTS THE RESULT ACROSS THE STATE WITH VALUES AROUND 50 TO THE NORTH AND LOWER 70S ACROSS SOUTHERN SECTIONS. ACTIVITY WAS ABLE TO DEVELOP ALONG SEABREEZE YESTERDAY BUT REMAINED JUST EAST OF THE FORECAST AREA. REGION CONTINUES TO FEED OFF RESIDUAL OUTFLOWS BUT EXPECT DRY CONDITIONS TO CONTINUE LOCALLY FOR THE REMAINDER OF THE OVERNIGHT PERIOD. ALONG TRANSITION ZONE OF DRY TO MOIST CONDITIONS...COULD SEE SOME REDUCTIONS TO VSBY PRIOR TO SUNRISE BUT NOTHING SIGNIFICANT EXPECTED AT THIS TIME. FOR TODAY...EXPECT VERY SIMILAR CONDITIONS TO SATURDAY...ALTHOUGH MOISTURE VALUES DO LOOK TO INCREASE. THIS COULD BE OFFSET SOMEWHAT BY MIXING AGAIN THIS AFTERNOON...BUT NOT EXPECTING THE DEGREE OF DEWPOINT REDUCTIONS NOTED IN ATL METRO YESTERDAY. IT SHOULD REMAIN JUST THE EXTREME SOUTHEAST CORNER OF THE FORECAST AREA THAT HAS POTENTIAL FOR THUNDERSTORM DEVELOPMENT THIS AFTERNOON. MOST ACTIVITY WILL REMAIN EAST OF THE AREA...BUT ENOUGH RISK OF OUTFLOW INDUCED ACTIVITY TO WARRANT INCLUSION OF SLIGHT CHANCE POPS. WILL ALSO BE MONITORING COLD CORE MID LEVEL SYSTEM LATE IN THE DAY PROGRESSING OUT OF THE NORTHERN PLAINS AND TOWARD THE GREAT LAKES. MODELS ACTUALLY PAINT LIGHT PRECIP FOR THE EXTREME NORTH THIS AFTERNOON BUT THIS LOOKS TO EARLY IN MY OPINION GIVEN SURFACE DRY AIR IN PLACE. SHOULD JUST BE AN INCREASE IN UPPER LEVEL CLOUDS AND WILL INDICATE SUCH IN THE GRIDS. FRONTAL BOUNDARY WILL SAG INTO THE AREA LATE SUN NIGHT THROUGH MONDAY. FEEL MOST OF THE ACTIVITY ASSOCIATED WITH THE SECONDARY FRONT WILL BE DIURNALLY DRIVEN AND WILL INDICATE HIGHEST POPS DURING THE AFTERNOON HOURS. FRONT WILL BE MOISTURE STARVED AND DOES NOT LOOK AS HEALTHY AS PREVIOUS RUNS AND WILL CONTINUE TO LIMIT POPS TO LOW END CHANCE. FRONT EASES INTO CENTRAL GEORGIA ON TUESDAY AND WILL NEED TO MONITOR FOR AN UPWARD ADJUSTMENT OF POPS AS MORE INSTABILITY WILL BE IN PLACE AND GFS INDICATES SUBTLE SHORT WAVE IN MEAN FLOW ARRIVING DURING MAX HEATING. LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... WILL AWAIT THE LATEST ECMWF BEFORE ANY SIGNIFICANT ADJUSTMENTS BUT HOPEFULLY MORE AGREEMENT WILL BE REACHED AMONG THE MODELS FOR THE EXTENDED. THE ONE THING THEY DO AGREE ON IS THE DEVELOPMENT OF STRONG EARLY FALL HIGH PRESSURE OVER THE UPPER MIDWEST A WEEK FROM NOW. THE QUESTION WILL BE WILL IT SHIFT EAST QUICKLY WITH UPPER RIDGE BUILDING IN OR STAY OVER THE TENNESSEE VALLEY ALLOWING FOR A COLDER PATTERN. NOTHING GOOD TO GO ON AT THIS POINT SO WILL STICK WITH THE WARMER MAV NUMBERS UNLESS THE NEW ECMWF COMPELS ME OTHERWISE. && .AVIATION... 18Z UPDATE... SCATTERED SHOWERS WITH ISOLATED THUNDERSTORMS ACROSS EAST AND SOUTH GEORGIA THIS AFTERNOON. THIS PRECIPITATION SHOULD STAY AWAY FROM THE TAF SITES SO NO PRECIPITATION IN THE TAF. CEILINGS MOSTLY VFR AND IT SHOULD STAY THAT WAY THROUGH 07Z-09Z. EXPECTING LOW STRATUS TO MOVE BACK IN WITH MOIST SOUTHEASTERLY FLOW OVER THE AREA. LOOKING FOR OVC010 AFTER 09Z AND CONTINUING THROUGH 14Z-16Z. CEILINGS WILL LIFT SLOWLY THROUGH THE DAY MONDAY WITH THE WINDS TURNING TO THE SW BY 14Z. WIND SPEEDS WILL BE IN THE 5-10KT RANGE THROUGH THE PERIOD. VSBYS SHOULD STAY VFR THROUGH THE PERIOD BUT MAY SEE SOME BRIEF PERIOD OF MVFR VSBYS OVERNIGHT. //ATL CONFIDENCE...18Z UPDATE...
