Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Peachtre/Fal Fld, GA (KFFC), launched 12:00Z, 2.4 hours before the alert went out and 180 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

Area forecast discussion, Jul 8, 5:31 AM EDT, 4 hours 54 minutes before

AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
531 AM EDT WED JUL 8 2009

.SHORT TERM /TODAY THROUGH FRIDAY/...

UPPER LOW CONTINUES TO SPIN OVER SOUTHEAST CANADA...WITH STRONG
SHORTWAVE WORKING ITS WAY AROUND THE LOW AND ACROSS THE SOUTHEAST.
WEAK BOUNDARY STILL IN PLACE ACROSS THE SOUTHEAST AS WELL...AND
THESE FEATURES WILL COMBINE WITH THE ABUNDANT MOISTURE (TYPICAL
SUMMERTIME PW VALUES BETWEEN 1.5-2) TO PRODUCE FAIRLY WIDESPREAD
SHOWERS AND THUNDERSTORMS...ESPECIALLY SOUTH OF THE FRONT. NORTH
GEORGIA MIGHT NOT SEE SO MUCH AS THE FRONT CONTINUES TO SLIDE
SLOWLY SOUTH IN RESPONSE TO THE SHORTWAVE MOVING THROUGH. HAVE
INCLUDED LIKELY POPS THIS AFTERNOON ACROSS A GOOD CHUNK OF THE
AREA...AND WITH BASIN-AVERAGE QPF UPWARDS OF 1-2...ITS POSSIBLE
THAT AS ECHOES TRAIN THIS AFTERNOON SOME LOCATIONS MAY HAVE HEAVY
RAINFALL PROBLEMS. WITH 250MB FLOW STILL 50+KT...AM NOT CONCERNED
ABOUT ANYTHING WIDESPREAD SO NO FLOOD/FLASH FLOOD WATCH
WARRANTED...ESPECIALLY SINCE THE SOILS IN CENTRAL GEORGIA CAN
LIKELY EASILY HANDLE THESE QPF AMOUNTS.

THE BOUNDARY WILL BE SLOW TO MOVE OUT AS THE SHORTWAVE/TROUGH AXIS
SORT OF STALLS OVER THE AREA THURSDAY INTO EARLY FRIDAY. BEST
CHANCES FOR RAIN WILL REMAIN ACROSS SOUTHERN ZONES. UPPER RIDGE
OVER THE SOUTHERN PLAINS WILL EXPAND EAST BEGINNING ON FRIDAY AND
WEAK SURFACE RIDGING WILL DOMINATE MOST OF THE AREA...THOUGH SOME
POPS WILL REMAIN IN CENTRAL GEORGIA.

TEMPERATURES WILL CONTINUE TO BE PROBLEMATIC THE NEXT COUPLE OF
DAYS WITH HIT AND MISS THUNDER AS WELL AS CLOUD COVER COMPLICATING
THE FORECAST. THE BIAS ADJUSTED MAV/MET BLEND WORKED FAIRLY WELL
YESTERDAY SO WILL CONTINUE THE TREND TODAY WITH MORE TWEAKS FOR
PERSISTENCE.

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...

STRONG UPPER LOW SLIDING ACROSS CENTRAL CANADA LATE IN THE WORK
WEEK WILL BEGIN TO TROUGH TOWARD THE OHIO VALLEY ON SATURDAY...
PUSHING THE UPPER HIGH BACK TOWARD THE DESERT SOUTHWEST. WEAK
FRONT ON THE LEADING EDGE OF THIS SYSTEM IS PROGGED TO PUSH TOWARD
THE APPALACHIANS OVER THE WEEKEND. IN GENERAL...THE SOUTHEAST IS
LEFT IN A WEAK UPPER FLOW REGIME WITH CONTINUED PLENTIFUL
MOISTURE IN THE COLUMN...SO HAVE KEPT SLIGHT CHANCE POPS IN THE
FORECAST FOR THE WEEKEND TO ACCOUNT FOR THE TYPICAL PULSE-TYPE
CONVECTION. THE DIFFUSE FRONT WILL MOVE INTO THE REGION SUNDAY
NIGHT INTO MONDAY AS GENERAL TROUGHINESS TAKES OVER THE EASTERN
THIRD OF THE COUNTRY...PLACING US IN WEAK NORTHWEST FLOW ALOFT.
HAVE INCREASED POPS AT THIS POINT WITH A MORE DIURNAL PATTERN.
TOWARD THE END OF THE PERIOD...MODELS DIVERGE WITH THE SOLUTIONS
AS GFS FLATTENS THE PATTERN OUT OVER US WHEREAS ECMWF CONTINUES
WEAK NORTHWESTERLY FLOW. HAVE LEFT IN A BLANKET SLIGHT CHANCE POPS
OVER THE AREA. NO MAJOR CHANGE IN TEMPS...THOUGH WITH ALL EXTENDED
MODELS DEVELOPING A RIDGE OVER THE ATLANTIC...EXTENDED GUIDANCE IS
ALL INDICATING AN INCREASE IN SURFACE MOISTURE DUE TO THE
INCREASED SOUTHERLY FLOW BY THE END OF THE PERIOD.

.AVIATION..
VFR CONDITIONS HOLDING OVER NORTHERN TAF SITES EARLY THIS
MORNING...WITH MAINLY SCT TO BKN MID/HIGH LEVEL CLOUDS OVER THE
AREA. OVER SOUTHERN TAF SITES IFR TO LIFR CIGS SPREADING INTO
CSG/MCN AREAS...AND AT THIS POINT NOT SURE HOW MUCH OR IF WE COULD
SEE SOME OF THESE LOWER CIGS WORK INTO THE NORTHERN SITES. THINK WE
COULD SEE SOME LOWER CLOUDS TOWARD MORNING...BUT MORE IN THE 1 TO 2
THSD FT RANGE...AND PLAN TO CONTINUE PREVIOUS FORECAST TREND WITH
CIGS POSSIBLY IN THE MVFR UNTIL AROUND LATE MORNING...THEN LIFTING
INTO THE LOW VFR/VFR RANGE BY NOON. WITH BOUNDARY OVER CENTRAL
GEORGIA AND MODELS SHOWING A WEAK SHORTWAVE SKIRTING ACROSS THE AREA
TODAY...THINK CHANCES FOR THUNDER A BIT BETTER THAN TUESDAY AND
LEANING TOWARD VCTS OR PROB30 MOST TAF SITES AFTER 18Z/20Z TIME
FRAME. WILL KEEP WINDS ON THE EAST SIDE OF NORTH FOR AREAS NORTH OF
THE BOUNDARY...WEST TO NORTHWEST MAY STILL BE OKAY FOR CSG AND MCN.
