The episode as NWS FFC wrote it up.
The southeast United States and mid-Atlantic region remained in a weakness area between two strong subtropical upper ridges of high pressure, one located in the western Atlantic and another in the desert southwest. A weak trough was noted in between these two highs from the Ohio Valley into the southeast U.S. With a hot, humid, unstable air mass remaining in place and unstable northwest flow aloft, albeit weak, scattered thunderstorms were the rule once again during the afternoon and evening. Some of these became strong to briefly severe. However, the biggest problem on this date was flooding and heavy rain. One thunderstorm near Cartersville in Bartow county dumped three to four inches of rain in two hours, causing considerable street flooding, flooding basements of homes and one business, and resulting in a roof collapse of a specialty store.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PEACHTREE CITY GA 240 PM EDT SUN JUL 18 2010 .SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/... UPPER TROUGH STILL IN PLACE OVER THE AREA...WITH UPPER HIGHS TO OUR EAST AND WEST. MCS THAT DEVELOPED IN THE UPPER MIDWEST IS SLIDING SOUTHEAST ALONG THE FLOW TOWARD THE OHIO VALLEY. GLOBAL MODELS NOT REALLY HANDLING THIS SYSTEM VERY WELL. NAM KEEPS THE SYSTEM A LITTLE TOO FAR NORTH AND GFS EXPERIENCING ITS TYPICAL CONVECTIVE FEEDBACK...THOUGH THE GFS'S MASS FIELDS ARE GENERALLY OKAY. ECMWF THE BEST OF THE THREE BUT STILL DOESN'T SEEM TO QUITE HAVE THE SYSTEM RESOLVED. MESOSCALE MODELS...RUC AND HRRR...SEEM TO BE MUCH BETTER...SO HAVE TRIED TO INCORPORATE SOME OF THESE MESOSCALE SOLUTIONS INTO THE FORECAST TO ACCOUNT FOR THE MCS- INDUCED VORT MAX THAT WILL BE HEADED THIS WAY. OF COURSE...THE VORT MAX IS COMPETING WITH THE SLOWLY BUILDING RIDGE...SO MOST OF THE VORT MAX'S EFFECTS WILL BE FELT UP IN NORTH GEORGIA. FOR THE SHORT-TERM...CONTINUED CHANCE POPS LOOKS GOOD FOR THE MOST PART...THOUGH THE VORT MAX MOVING THROUGH MONDAY AFTERNOON IN THE MOUNTAINS MAY WARRANT SLIGHTLY HIGHER POPS. TEMPS REMAIN NEAR NORMAL...THOUGH WITH THE BUILDING RIDGE EXPECT A SLOW WARM UP. DUE TO THE MODEL UNCERTAINTIES ALL AROUND...MAINLY TOOK A BIAS- ADJUSTED MAV/MET BLEND FOR BOTH POPS AND TEMPS...WITH SOME TWEAKING OF POPS TO ACCOUNT FOR THE RUC/HRRR SOLUTIONS ESPECIALLY MONDAY AFTERNOON AS THE VORT MAX PUSHES THROUGH. .LONG TERM /WEDNESDAY THROUGH SUNDAY/... SURFACE HIGH BUILDS IN FROM THE WESTERN ATLANTIC BY MIDWEEK...AS UPPER RIDGE DOMINATES THE ENTIRE SOUTH. NO REAL CHANGE TO THIS PATTERN THROUGH THE EXTENDED...THOUGH BOTH THE GFS AND ECMWF INDICATE A WEAK SHORTWAVE PUSHING THROUGH THE OHIO VALLEY LATE IN THE WEEKEND...WHICH MAY SERVE TO WEAKEN THE RIDGE JUST A TAD. HIGH TEMPS ABOVE NORMAL...WITH MID AND UPPER 90S EXPECTED ACROSS MOST OF THE AREA. SUMMERTIME PATTERN WARRANTS CONTINUATION OF SLIGHT TO LOW CHANCE POPS EACH DAY.

The Atlanta radar (KFFC), 92 km away, was scanning. The volume nearest the first event began at 21:24 UTC.
1 thunderstorm wind, 1 heavy rain. Local standard time, as filed.
The Bartow County Emergency Management Director reported that at least nine trees were down around Cartersville, some on power lines.
Fox 5 Television of Atlanta, along with other Atlanta broadcast media and the Cartersville Daily Tribune reported that heavy rain flooded several downtown Cartersville businesses as well as causing a partial roof collapse of the Hobby Lobby store at the Market Square Shopping Center. Three to four inches of rain had fallen in a small area around downtown Cartersville during the previous two hours. Considerable damage was reported to the store building and its contents, many of which were destroyed by rain water. However, no injuries were reported as a result of the incident.
Several other downtown businesses suffered water damage when several inches of water crept into the structures, including Four Way Lunch, Swheat Market, City Cellar, and Moore's Market. Several nearby homes on Herring Street were flooded with 2.5 to 3.0 feet of water. Seven residents of these homes were rescued from the flooded homes. Finally, the Keith Building, a city building, on Leake Street sustained significant water damage when water rose nearly two feet deep in the lower level of the structure. Minor flooding was also observed at the building housing the Cartersville Daily Tribune.
Most of the flooding was determined to be the result of a clogged drainage ditch near the CSX Railroad tracks. This prevented the heavy runoff water from reaching the nearby Etowah River.
