The episode as NWS FFC wrote it up.
The upper atmospheric and surface pattern remained virtually unchanged across the southeastern U.S. A stationary front remained from the eastern Tennessee Valley into the Southern Plains. A negatively tilted upper trough persisted across the mid-south and southeast U.S. A warm, moist, unstable environment persisted across north and central Georgia. Saturated ground and additional rainfall led to stream, creek, and river flooding in parts of north and central Georgia. A few thunderstorms became severe and produced damaging downburst winds and marginal severe hail.

NWS Atlanta, GA wrote its last area forecast discussion before the first event at May 6, 4:44 AM EST, 56 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED FOR AVIATION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 544 AM EDT WED MAY 6 2009 .SHORT TERM /TODAY THROUGH FRIDAY/... VERY ACTIVE WEATHER DAY EXPECTED ACROSS THE CWA...AND IT COULD GET STARTED EARLY THIS MORNING. ALL FACETS OF SEVERE WEATHER AND FLOODING EXPECTED TODAY. COMBINED PROJECTED INSTABILITY AND SHEAR ACROSS THE CWA THIS AFTERNOON SUPPORTIVE OF WIDESPREAD SEVERE THUNDERSTORMS AND HEAVY RAINFALL. NOW FOR THE DETAILS...A WEAK TROUGH OF LOW PRESSURE REMAINS ACROSS THE TN VALLEY. NUMEROUS OUTFLOW BOUNDARIES RESIDE ACROSS CENTRAL/N GA FROM TUE AFTERNOON TSRA ACTIVITY ACROSS CENTRAL GA. A MOIST AIR MASS REMAINS IN PLACE WITH DEWPOINTS FROM THE LOW 60S N GA TO THE LOW 70S SOUTH GA. MEANWHILE...A STRONG SHORT WAVE ACROSS THE MIDWEST/SOUTHERN PLAINS...WAS MOVING RAPIDLY ESE TOWARD THE SE U.S. EARLY THIS MORNING. THIS SYSTEM WILL DEEPEN AND TAKE ON A NEGATIVE TILT AS IT ROTATES THROUGH THE SE U.S. BETWEEN 18Z AND 06Z...SIMULTANEOUSLY PUSHING A SFC BOUNDARY SOUTHWARD INTO CENTRAL GA BY THU MORNING. EXCESSIVE INSTABILITY AND STRONG SHEAR PROGGED BY THE GFS...WITH 3000+ CAPES...300 M2/S2 HELICITY ACROSS NW GA ACCOMPANYING A 50-55KT LLJ...AND ACCOMPANYING EHI VALUES OF 5.0...ALL INDICATIVE OF A POTENTIALLY MAJOR TORNADO OUTBREAK. HOWEVER...THE ECMWF/NAM ARE CONSIDERABLY LESS AGGRESSIVE WITH INSTABILITY AND SHEAR...INDICATING MORE MODEST AMOUNTS OF 1500 MAX CAPE AND A 40-45KT LLJ...NONETHELESS STILL MORE THAN ADEQUATE FOR A SUBSTANTIAL SEVERE WEATHER OUTBREAK. THE MAIN CONCERN THAT COULD REDUCE THE SEVERE WX THREAT IS EARLY MORNING ACTIVITY. WIDESPREAD CONVECTION UPSTREAM...SOMEWHAT IN THE FORM OF AN MCS...ACROSS AR/TN/MS SHOULD SPREAD INTO NW GA BY 12Z AND THEN THROUGH THE REMAINDER OF N GA BY 18Z. THE RAIN COOLED AIR AND MESO HIGH BEHIND THIS INITIAL CONVECTION MAY HELP TO STABILIZE THE AIR MASS OVER N GA...BUT WOULD STILL LEAVE CENTRAL AND EAST GA SUSCEPTIBLE TO LEADING OUTFLOW BOUNDARIES AND A MUCH MORE UNSTABLE ENVIRONMENT. SPC STICKING WITH A SLIGHT RISK AT THIS TIME...BUT IF THE SEVERE WEATHER PARAMETERS ADVERTISED BY THE GFS ARE REALIZED...EVEN IN PART...A MODERATE RISK MAY BE IN ORDER. PROGGED SHEAR AND HELICITY...ESPECIALLY ACROSS NC/NW GA LEAD ME TO BELIEVE THAT ROTATING STORMS CAN BE EXPECTED TODAY. CONVECTIVE MODE IS NOT ENTIRELY CLEAR...AND A MULTICELLULAR MODE WOULD REDUCE THE THREAT OF LONG-LIVED TORNADOES...BUT BY NO MEANS ELIMINATE THE THREAT. EMERGENCY MANAGERS NEED TO REMAIN ABREAST OF THE SITUATION TODAY ACROSS THE ENTIRE CWA. FINALLY...IT SHOULD BE NOTED THAT SEVERE WEATHER CANNOT BE RULED OUT EVEN WITH LEADING ACTIVITY EARLY THIS MORNING...AS THE 40-50KT LLJ BEGINS TO ADVECT INTO NW GA BETWEEN 12Z-18Z. ANOTHER CONCERN TODAY IS FLOODING. HPC HAS NOW INCLUDED MUCH OF N GA IN A RISK FOR EXCESSIVE RAINFALL...WITH A MODERATE RISK FOR EXCESSIVE RAINFALL FROM NW GA BACK INTO N AL/N MS. THE GFS SUGGESTS THAT TRAINING OF CONVECTIVE CELLS ACROSS N GA MAY CONTINUE FOR SEVERAL HOURS FROM MORNING THROUGH AFTERNOON...BEFORE THE AXIS OF HEAVIER CONVECTION DRIFTS FURTHER SOUTH INTO CENTRAL GA. GFS HAS CONSIDERABLE CONVECTIVE FEEDBACK PROBLEMS SHOWING 6+ INCHES OF RAIN ACROSS THE ATL METRO AREA. THE ECMWF/NAM 2-3 INCH AMOUNTS ARE MORE REASONABLE...BUT LOCALIZED 4-5 INCH AMOUNTS CANNOT BE RULED ACROSS NC/NW GA. THUS...HAVE NO QUALMS ABOUT ISSUING A FLOOD WATCH FOR MUCH OF N GA WHERE FFG VALUES ARE IN THE 2-3 INCH/6 HR RANGE...GENERALLY NORTH OF A CARROLLTON...TO ATLANTA...TO LAWRENCEVILLE...TO WINDER...TO HOMER FROM 12Z TODAY TO 12Z THU. ALTHOUGH RAINFALL ACROSS THESE AREAS WILL DIMINISH AFTER 06Z...LINGERING CREEK AND STREAM FLOODING WARRANT CONTINUING THE FLOOD WATCH INTO THU MORNING. AREAS SOUTH OF ATL-AHN HAVE SEEN CONSIDERABLY LESS RAINFALL RECENTLY AND FFG VALUES ARE IN THE 4-5 INCH/6 HR RANGE...WHICH ARE NOT ANTICIPATED AT THIS TIME. WILL CONTINUE THE WIND ADVISORY AS IS...ALTHOUGH THE SUPPORT FOR SUCH IS MARGINAL...MAINLY HINGED UPON THE LLJ AFFECTING THE HIGHER ELEVATIONS OF N GA. THE MAIN CONCERN WOULD BE THAT EVEN 20-25 MPH WINDS WITH THE SATURATED GROUND WILL RESULT IN DOWNED TREES AND POWER LINES. FEEL THAT SUCH EFFECTS WILL BE LOST WITH ONGOING TSRA ACTIVITY...HOWEVER. THE STRONG SHORT WAVE MOVES EAST OF THE AREA THU AND CONSIDERABLY QUIETER WX CONDITIONS ARE EXPECTED. THE ECMWF HAS FOR SEVERAL DAYS INDICATED THAT LITTLE IF ANY CONVECTIVE ACTIVITY WILL OCCUR THU...ALTHOUGH SOME MAY LINGER IN THE FAR SE PART OF THE CWA IN THE EARLY MORNING. THE GFS IS GENERALLY NOW ON BOARD WITH THE ECMWF IN MINIMAL IF ANY POPS ACROSS THE NW 2/3RD OF THE CWA AFT 12Z THU. HOWEVER...AN ACTIVE ZONAL FLOW CONTINUES ALOFT...WITH THE NEXT...ALBEIT WEAKER SHORT WAVE/FRONTAL SYSTEM SLATED TO DRIFT INTO THE AREA FROM THE W/NW BY SAT. GIVEN THE GENERAL CONSENSUS THAT THERE WILL BE CONSIDERABLE DRYING BEHIND TODAYS STRONG SHORT WAVE...PLAN TO REDUCE POPS TO LESS THAN 15 PERCENT ACROSS ALL EXCEPT THE FAR SE FOR THU...AND ALL AREAS AFT 00Z THU WHEN THE UPPER TROUGH SHIFTS OFF THE COAST. FOR TEMPS...ALTHOUGH THE MAV ACTUALLY HAD LESS BIAS TUE THAN THE MET FOR A RARITY...I AM SIDING WITH THE GENERALLY COOLER MET MOS NORTH AND SLIGHTLY WARMER CENTRAL AREAS...GIVEN EXPECTED CLOUD COVER AND PCPN. VERY LITTLE IMPROVEMENT OVER GUIDANCE TO GAIN ON MIN TEMPS TONIGHT WITH CLOUDS AND PCPN IN PLACE...AND A GENERALLY UNIFORM AIR MASS. MORE BREAKS IN THE CLOUDS THU SHOULD ALLOW FOR SLIGHTLY WARMER .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... AN ACTIVE ZONAL FLOW IS EXPECTED TO CONTINUE...BUT THERE ARE SIGNS...AS THE ECMWF HAS BEEN ADVERTISING FOR DAYS THAT A BROAD SUBTROPICAL RIDGE WILL EVENTUALLY AMPLIFY FROM THE SW/SC U.S. HOWEVER...THIS WILL NOT OCCUR BEFORE A SERIES OF SHORT WAVES TRACK ACROSS THE AREA IN THE MEAN WNW FLOW ALOFT...BRINGING ADDITIONAL ROUNDS OF CONVECTION TO THE AREA THROUGH THE WEEKEND. THE GFS NOW AGREES WITH THE ECMWF THAT A BONA FIDE COLD FRONT WILL BE PUSHED SE THROUGH GA BY MON AS THE UPPER FLOW BEINGS TO AMPLIFY. THERE APPEAR TO BE SEVERAL SUBTLE SHORT WAVES THAT TRACK ACROSS THE AREA IN ADVANCE OF THE FINAL PUSH MON...SO THE WEEKEND LOOKS UNSETTLED ONCE AGAIN TO SAY THE LEAST...WITH THE CHANCE FOR MORE TSRA...HEAVY RAIN...AND SEVERE WX. HOWEVER...THE MAIN THREAT WOULD BE IN THE FAR NORTH...WITH SOUTHERN AREAS MORE CAPPED THAN RECENTLY...AT LEAST FRI-SAT. BEYOND EARLY NEXT WEEK...THE GFS NOW ALSO COMING INTO AGREEMENT WITH THE ECMWF IN DEVELOPING A MAMMOTH SUBTROPICAL RIDGE ACROSS THE SE U.S. 500MB HEIGHTS RISE INTO THE 590+ RANGE AND 850MB TEMPS APPROACH +20C. LOW-LEVEL MOISTURE LINGERS OVER THE AREA...ESPECIALLY WITH A LARGE BERMUDA HIGH NOSING INTO THE SE U.S....PUSHING ATLANTIC MOISTURE INTO THE REGION. TYPICAL...SUMMERTIME DIURNAL PULSE THUNDERSTORMS CANNOT BE RULED OUT WITH THIS PATTERN. FOR TEMPS...THE WEEKEND SHOULD BE SEASONABLY WARM IN ADVANCE OF THE MON COLD FRONT. FOR THE LATER PORTION OF THE EXTENDED...THE PATTERN WOULD SUGGEST WELL ABOVE AVERAGE TEMPS...BUT THE PRESENCE OF AN ATLANTIC SFC HIGH AND EASTERLY LOW-LEVEL MARITIME FLOW MAY TEMPER TEMPS SOMEWHAT. WILL SIDE WITH THE NEAR CLIMO MEX READINGS FOR NOW. && .AVIATION... CONVECTIVE ACTIVITY IN NW GA WILL CONTINUE TO WEAKEN AS IT SPREADS SOUTHWARD. EXPECT THIS TO BE ONLY -SHRA BY THE TIME IT REACHES ATL BY 13-14Z THIS MORNING. MVFR CIGS WILL PREVAIL THIS MORNING...THEN RISE TO VFR HGTS BY 17Z. EXPECT TSTM DEVELOPMENT BY 17-18Z IN THE ATLANTA AREA AS DRIVING UPPER TROUGH CURRENTLY MOVING INTO NORTH MS APPROACHES. COULD SEE A COUPLE ROUNDS OF STORMS TODAY... SO PLAN TO CONTINUE TO SHOW THREAT OF TSTM IN ATLANTA INTO THE EVENING. CIGS SHOULD LOWER TO MVFR BY LATE EVENING...THEN POSSIBLY IFR BY 09Z TONIGHT. WILL KEEP WINDS ON THE WEST SIDE OF SOUTH THROUGH THE PERIOD. EXPECT WINDS TO GET A BIT GUSTY THIS AFTERNOON. /39 && .PRELIMINARY POINT TEMPS/POPS...

THERE IS A THREAT OF HEAVY RAIN AND LOCALIZED FLOODING FROM TRAINING STORMS. AN AREA OF SHOWERS AND THUNDERSTORMS WILL PUSH INTO NORTH GEORGIA THIS MORNING. THIS WILL HELP SATURATE THE GROUNDS AND LEAVE OUTFLOW BOUNDARIES FOR REDEVELOPING STORMS LATER THIS AFTERNOON. WIDESPREAD RAINFALL AMOUNTS OF 2 TO 3 INCHES... WITH SOME LOCALIZED HIGHER AMOUNTS ARE EXPECTED... MAINLY ALONG AND NORTH OF A LINE FROM CARROLLTON TO ATLANTA TO LAWRENCEVILLE TO HOMER. A FLOOD WATCH HAS BEEN POSTED FOR THIS AREA. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY THUNDERSTORMS ARE POSSIBLE EACH DAY...EXCEPT NORTH GEORGIA ON THURSDAY OR CENTRAL GEORGIA ON FRIDAY AND SATURDAY. .SPOTTER INFORMATION STATEMENT...
