The episode as NWS FFC wrote it up.
A broad upper trough lingered just off the east coast of the United States. This trough extended southwest into the southeast United States. The southwest lagging part of this trough became detached from the mean flow and cutoff into a weak upper low across Alabama between May 29th and May 30th. The combination of deep moisture, diurnal instability, and the upper low just to the west of Georgia provided ample support for scattered to numerous afternoon and evening showers and thunderstorms. With the upper low immediately to the west, mid-level southeast flow resulted in a general southeast to northwest movement of the showers and thunderstorms. Although a few of the storms approached severe limits, no thunderstorms meeting severe criteria were reported. Frequent cloud-to-ground lightning and heavy rain were observed with many of the storms.
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 May 29, 2:01 PM EST, 10 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 301 PM EDT SAT MAY 29 2010 .SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/... CUTOFF UPPER LOW CENTERED OVER THE DEEP SOUTH THIS AFTERNOON WILL CONTINUE THE PATTERN OF UNSTABLE WEATHER FOR THE NEXT COUPLE OF DAYS. LONGWAVE OMEGA BLOCK IN PLACE WILL PREVENT THE CUTOFF LOW FROM MOVING MUCH OVER THE NEXT DAY OR SO...THOUGH BY MONDAY A STRONG UPPER LOW PUSHING INTO CENTRAL CANADA AND THE NORTHERN PLAINS WILL BEGIN TO ABSORB THE DEEP SOUTH LOW. NAM/GFS/ECMWF GENERALLY IN AGREEMENT THROUGH THE SHORT TERM...AT LEAST ON THE MASS FIELDS...THOUGH THERE ARE THE NATURAL DIFFERENCES IN DETAILS. MOISTURE AND INSTABILITY (CAPES WIDESPREAD BETWEEN 1500-2000 J/KG) IN PLACE ACROSS THE SOUTHEAST WILL CONTINUE WITH SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS. ADDITION OF THE UPPER LOW WILL KEEP SOME COOLER AIR ALOFT ACROSS THE REGION...AND THUS THE CHANCE REMAINS FOR ISOLATED SEVERE SUNDAY INTO MONDAY...WITH HAIL AND/OR DAMAGING WINDS AS THE MAIN THREATS. SOME AREAS COULD GET SOME HEFTY RAINFALL AMOUNTS. BASIN AVERAGE QPF ANYWHERE FROM 0.5"-1.5" THROUGH THE DAY SUNDAY...BUT IN LOCALIZED AREAS COULD SEE MORE THAN THAT. DO NOT SEE ENOUGH OF A RISK OF FLOODING/FLASH FLOODING TO ISSUE A FLOOD WATCH AT THIS TIME...BUT WOULD NOT BE SURPRISED IF A FEW FFWS NEED TO BE ISSUED DURING THE COURSE OF THE WEEKEND. PRECIPITABLE WATER APPROACHING 2" SUNDAY AFTERNOON...SO ANY STORM THAT DEVELOPS (SEVERE OR NOT) WILL BE ABLE TO DUMP SOME HEAVY RAIN. MAIN ISSUE WILL BE LIGHTNING...AS IS NORMALLY THE CASE DURING THESE SUMMERTIME THUNDERSTORMS. THE SPINNING OF THE UPPER LOW WILL ALLOW FOR THE THUNDERSTORM CLUSTERS TO BE SOMEWHAT ORGANIZED (RATHER THAN PROPAGATING SOLELY ON THEIR OUTFLOWS). IN GENERAL IT JUST LOOKS LIKE A STORMY WEEKEND...WITH HOPEFULLY ENOUGH BREAKS BETWEEN THE STORMS TO ALLOW FOR SOME MEMORIAL DAY CELEBRATIONS. AS MENTIONED ABOVE...NORTHERN PLAINS TROUGH WILL BEGIN TO ABSORB THE DEEP SOUTH CUTOFF LOW ON MONDAY. WEAK FRONT ASSOCIATED WITH THE NORTHERN SYSTEM WILL BE ENHANCED SOMEWHAT LATE MONDAY INTO MONDAY NIGHT AS THE SYSTEMS PHASE AND BEGIN TO PUSH THROUGH. HIGH CHANCE TO LIKELY POPS WILL CONTINUE THROUGH THE HOLIDAY WEEKEND. MAINLY TOOK A BIAS-ADJUSTED BLEND FOR TEMPERATURES...BUT SHORT TERM HIGHS MIGHT BE INTERESTING DEPENDING ON EXTENT OF CLOUD COVER. IF A LITTLE MORE SUNSHINE BREAKS THROUGH...SOME AREAS COULD SEE SOME UNCOMFORTABLE (HOT AND HUMID) AFTERNOONS. FOR NOW AM STICKING WITH NEAR CLIMATOLOGICAL NORMALS FOR AFTERNOON HIGHS... WITH A LITTLE ABOVE NORMAL FOR LOWS DUE TO THE PLENTIFUL MOISTURE. .LONG TERM /TUESDAY THROUGH SATURDAY/... EXTENDED BEGINS AS TROUGH AND ASSOCIATED FRONT MOVE THROUGH... PUSHING THE UPPER RIDGE INTO THE WESTERN ATLANTIC. FRONT SORT OF STALLS AND WASHES OUT ACROSS THE SOUTHEAST AS THE NEXT SYSTEM MOVES OFF THE ROCKIES AROUND MIDWEEK. GFS A LITTLE FASTER THAN THE ECMWF WHICH IN TURN IS A LITTLE DEEPER WITH THE SYSTEM...BUT STILL FAIRLY DECENT AGREEMENT. TROUGH AXIS BEGINS TO PUSH THROUGH THE MISSISSIPPI VALLEY ON THURSDAY...AND WITH WEAK SOUTHWEST FLOW ALOFT THE CHANCE OF THUNDER WILL REMAIN IN THE FORECAST THROUGH MOST OF THE EXTENDED. SOME DRYING INDICATED FOR THE WEEKEND ON THE GFS...BUT ECMWF STILL HANGS ONTO SOME MOISTURE. WOULDN'T BE SURPRISED TO SEE THE PULSE-LIKE THUNDERSTORM PATTERN CONTINUE. FOR NOW...WEDNESDAY LOOKS LIKE THE WARMEST DAY OF THE BUNCH JUST AHEAD OF THE MIDWEEK SYSTEM. OTHERWISE...TEMPS LOOK JUST ABOVE NORMAL. TDP && .PRELIMINARY POINT TEMPS/POPS...
