The episode as NWS FFC wrote it up.
A tropical low pressure area was moving west across the northern Gulf of Mexico. At 7 am EST on the 21st, the tropical low was located just off the Florida coast near Pensacola. Bands of showers and thunderstorms were rotating counterclockwise around the low into south and as far north as the southern portions of central Georgia. Some weak rotation was noted in the stronger thunderstorms. One of these thunderstorms moved north into Sumter county causing wind damage in the southeast part of the county.

NWS Atlanta, GA wrote its last area forecast discussion before the first event at Sep 21, 5:10 AM EST, 9 hours 23 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PEACHTREE CITY GA 610 AM EDT FRI SEP 21 2007 .UPDATE... AM IMMEDIATELY INCREASING POPS FOR SOUTHERN 1/3RD OF THE CWA. OUTER BAND FROM DEVELOPING TROPICAL SYSTEM CREEPING INTO CRISP...WILCOX...AND TELFAIR COUNTIES AND SHOWS NO SIGNS OF DISSIPATING. APPEARS TO BE MOSTLY VERY HEAVY RAIN WITH LITTLE LIGHTNING NOTED OUTSIDE OF COASTAL THUNDERSTORMS. 50DBZ CORES ONLY ABOUT 14K. WILL HAVE LIKELY POPS IN THIS AREA FOR THE MORNING HOURS. && .SHORT TERM /TODAY THROUGH SUNDAY/... IMMEDIATE CONCERN IS SUBTROPICAL/TROPICAL SYSTEM MOVING VERY SLOWLY WEST OFF THE WEST COAST OF FL. CLOUDS FROM THIS SYSTEM SPREAD INTO THE FFC CWA THU COURTESY OF DEEP EASTERLY MARITIME FLOW. A FEW SPRINKLES ALSO OBSERVED HERE AND THERE BECAUSE OF UPSLOPE FLOW OVER THE SHALLOW COOL/DRY SFC LAYER. HOWEVER...SO FAR MOST OF THE SIGNIFICANT PCPN HAS REMAINED SOUTH OF THE FFC CWA. HEAVY BANDS OF SHRA AND A FEW TSRA JUST ACROSS THE SOUTHERN BORDER OF THE CWA OVERNIGHT...BUT MAKING LITTLE PROGRESS NORTHWARD GFS INITIALIZING BETTER AND NOT SHOWING BRIEF JOG NORTHWARD OF LOW INTO SW GA AS DOES THE NAM. GFS SEEMS TO HAVE BETTER HANDLE ON SYSTEM...ALTHOUGH NO REAL SIGNIFICANT DIFFERENCES AMONG THE NAM/GFS. THE GFS SHOWS THAT THE CURRENT BAND OF SHRA/TSRA ACROSS N FL...ALBEIT IN A WEAKENED FASHION...WILL DRIFT INTO N/W GA BY AFTERNOON. MEANWHILE...THE UPPER HIGH IS OSCILLATING AROUND THE GULF LOW...AND WILL GRADUALLY SHIFT FROM ITS CURRENT POSITION OVER THE ARKLATEX REGION TOWARD THE TN VALLEY...AND THEN TOWARD THE SOUTHERN APPALACHIAN REGION BY THE WEEKEND. THUS...THE MAIN EFFECT OF THE TROPICAL/SUBTROPICAL SYSTEM SHOULD BE SHUNTED NW INTO THE MID-SOUTH AND ARKLATEX REGION ON THE SOUTHERN SIDE OF THE SUBTROPICAL RIDGE...BUT JUST CLOSE ENOUGH TO KEEP ABUNDANT CLOUDS AND AT LEAST SOME LIGHT SHRA ACROSS THE CWA THROUGH THE SHORT TERM AND INTO THE LONG TERM PERIODS. MODEL SOUNDINGS SHOW AN INCREASINGLY TROPICAL AIR MASS IN PLACE AS FAR NORTH AS ATL-AHN BY 00Z THIS EVENING...WITH NEAR SATURATION THROUGHOUT THE ATMOSPHERIC COLUMN...NOTE PW OF 1.83. THE SOUNDING BECOMES ESSENTIALLY A MOIST ADIABATIC ONE BY EVENING. THERE DOES APPEAR TO BE SOME POTENTIAL FOR TSRA WITH THE K INDEX RISING TO 32 AND THE LI OF -1 AND KI OF 32. WARM AIR ALOFT...-4C TO -5C AT 500 MB...ABUNDANT CLOUD COVER...AND THE OVERALL LACK OF ANY REAL FOCUSING MECHANISM SHOULD HOLD TSRA THREAT TO THE SOUTHERN PART OF THE CWA NEAREST THE UPPER LOW. ADDITIONAL BANDS OF SHRA AND ISOLD TSRA WILL AFFECT THE CWA SAT-SUN AS THE SUBTROPICAL/TROPICAL LOW CONTINUES ITS NW TRACK. THIS PUTS THE FFC CWA IN A MOIST SE FLOW. THE THREAT FOR TSRA SAT...AND ESPECIALLY SUN...APPEARS GREATER THAN TODAY AS SOME BREAKS IN THE OVERCAST WILL ALLOW TEMPS TO WARM INTO THE 80S LEADING TO BETTER INSTABILITY. TEMPS WILL BE HELD DOWN TODAY BECAUSE OF ABUNDANT CLOUD COVER. SLIGHTLY WARMER TEMPS CAN BE EXPECTED SAT-SUN AS THE MAIN EFFECTS OF THE LOW MOVE TO THE WEST OF THE AREA AND THE SUBTROPICAL RIDGE BUILDS DOWN FROM THE NORTH. TEMPS WILL LIKELY BE ABOVE CLIMO FOR THE WEEKEND...ESPECIALLY IN THE NORTH NEAREST THE UPPER HIGH. .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... THE GFS HAS BEEN PRETTY CONSISTENT THE PAST SEVERAL DAYS ON TAKING THE TROPICAL/SUBTROPICAL SYSTEM TOWARD THE LA COAST BY THE WEEKEND. THEN...THE REMNANTS OF THE SYSTEM TRACK NNW INTO THE ARKLATEX REGION AND ARE EVENTUALLY PICKED UP BY A STRONG SHORT WAVE MOVING IN FROM THE WESTERN STATES. THE UKMET/ECMWF HAVE A FURTHER WESTWARD TRACK WITH THE TROPICAL SYSTEM...TAKING THE CENTER OF CIRCULATION INTO TX INSTEAD OF TURNING IT NORTH IN WESTERN LA. THE SREF ALSO SHOWS A FURTHER WESTWARD TACK AS WELL. AT ANY RATE...THE BULK OF THE ASSOCIATED PCPN SHOULD MOVE INTO THE MIDWEST AROUND THE SUBTROPICAL RIDGE...WHICH BY EARLY NEXT WEEK WILL BE LOCATED JUST OFF THE MID-ATLANTIC COAST. MOST OF THE SUBSTANTIAL HEAVY SHRA/TSRA WITH THE LOW REMAINS NEAR THE COASTAL AREAS UNTIL IT IS PICKED UP BY THE WESTERN TROUGH TOWARD THE WEEKEND/EARLY NEXT WEEK...AT WHICH POINT THE HEAVIER RAINS SPREAD NORTH THROUGH LA/AR ALONG AN ADVANCING FRONTAL SYSTEM. THE BEST CHANCE OF RAIN FOR THE FFC CWA WILL COME WHEN A COLD FRONT TAPS INTO THE REMAINING MOISTURE AND SPREADS SE INTO THE AREA TUE-WED. THERE IS A NOTICEABLE DRYING TREND ACROSS THE N/E SECTIONS MON-TUE IN ADVANCE OF THE FRONT AS A MID-ATLANTIC SFC HIGH SPREADS MUCH DRIER AIR INTO THE AREA FROM THE NE. THIS COULD INITIALLY HINDER SHRA/TSRA DEVELOPMENT WITH THE FRONT. WILL NEED TO MONITOR THIS DRYING TREND IN LATER RUNS TO ASSESS ITS ROLE IN POTENTIALLY REDUCING FRONTAL SHRA/TSRA ACTIVITY. NO SIGNIFICANT COOLING FORSEEN IN THE NEXT 10 DAYS. 850MB TEMPS HOVER IN THE +16 TO +18C RANGE...WITH ANY NOTICEABLE COLD AIR WELL NORTH UP IN CANADA. THUS EVEN AFTER FRONTAL PASSAGE...COOLING WILL BE NEGLIGIBLE. CONFIDENCE IN LATER PERIODS OF THE EXTENDED LOW WITH RESPECT TO PCPN. GFS SHOWS ALL ACTIVITY SOUTH AND EAST OF THE CWA BY DAY 7...BUT A WESTERLY FLOW WITH WEAK EMBEDDED SHORT WAVES STILL NOTED ALOFT. HAVE LEFT SAT DRY FOR NOW...BUT THIS COULD CHANGE WITH LATER RUNS. && .AVIATION...DEEP EASTERLY FLOW SUPPORTING SOLID LAYER OF STRATUS OVER GEORGIA THIS MORNING. MOST OF IT IS IFR WITH PATCY DRIZZLE OVER NORTH AND CENTRAL SECTIONS. THIS SHOULD CONTINUE THROUGH LATE MORNING...GRADUALLY LIFTING ABOVE 3 THSD FT AROUND 18Z. SHOWERS SHOULD SPREAD NORTHWARD DURING THE DAY...BUT CONVECTION SHOULD BE LIMITED TO AREAS SOUTH OF COLUMBUS TO MACON. WIND WILL REMAIN EAST TO NORTHEAST TODAY 10 TO 15KT WITH HIGHER GUSTS. VISIBILITY SHOULD REMAIN UNRESTRICTED EXCEPT NEAR 3SM IN PATCHY DRIZZLE OR FOG UNTIL 14Z...AND IN SHOWERS OR THUNDERSTORMS LATER TODAY. && .PRELIMINARY POINT TEMPS/POPS...
