The episode as NWS FFC wrote it up.

Isolated heavy rainfall amounts produced localized flash flooding in the Atlanta metropolitan area.
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 Jul 16, 2:47 PM EST, 13 minutes earlier.
Area Forecast Discussion National Weather Service Peachtree City GA 347 PM EDT Sun Jul 16 2017 .SHORT TERM /Tonight through Monday Night/... Primary concern in the short term period is timing and likelihood of diurnally driven convection. Storms today greatly affected by morning remnants of MCS which moved over middle GA and south ATL metro counties. New convection focused as expected to the south and east of the old complex and MCV (mesoscale convective vortex). See breeze convection over the west FL gulf coast also in a favorable pattern for northward propagation and will affect far southern counties with widespread SHRA/TSRA and possible flooding. Over most of north GA including ATL metro, could see an isolated SHRA but most of this area will remain too stable for significant deep convection. After south/middle GA storms diminish after 02Z, should be fairly quiet tonight. Not expecting a repeat MCS like last night. Moist plume and nearly washed out stationary front should remain over south and middle GA Monday, where better coverage of TSRA will be in the afternoon/evening. Low level moisture still high over north GA so isolated convection still likely. Slight chance PoPs seem prudent. Will continue to monitor rainfall amounts over southern counties. Even though reflectivity trends indicate MCS forming in SW GA, rainfall amounts so far have mainly been 1-2" with isolated higher amounts. SNELSON .LONG TERM /Tuesday through Sunday/... No big changes in the long term. Models continue to show some drying for the north into the week...with the upper ridge building back over our area by the weekend. However not enough drying to remove pops completely except for a couple of night time periods mid week. Previous discussion is included below. 41 && LONG TERM /Monday Night through Saturday/... Main frontal system from the short term will have moved into south GA by the beginning of the extended. By Monday night the deeper moisture will have also moved south and east of the area but there is still some mid to lower level moisture across the region. Drier air does move into the area beginning Tuesday but will still see the diurnal convective trend continue through day 7 with instabilities increasing every afternoon. With a ridge building into the area Wednesday and a bit drier air mass across the region...This will mean hotter temps for the end of the extended forecast. Temps will have no problem pushing into 90s across the area. 01 AVIATION... 18Z Update... Main concern is when and if TSRA develops over rest of north and central GA this afternoon. Morning complex of storms that moved in from AL has dissipated and left the atmosphere fairly stable over ATL metro and middle GA airports. With breaks in clouds, could see some late development so have pushed TEMPO TSRA back to 21-23Z. If clouds do not continue to clear, will likely remove this TEMPO. Small chance for morning MVFR fog around 10-11Z Monday. Any SHRA/TSRA not likely until after 19Z Monday. Sfc winds will remain SW 4-8kts. //ATL Confidence...18Z Update... Medium confidence on TSRA coverage and timing. High confidence on all other elements. SNELSON && .PRELIMINARY POINT TEMPS/POPS...

The Telfair County Emergency Manager reported a tree blown down onto Cheney Street in Lumber City.
Public reported that Horizon Drive was flooded between Old Peachtree Road and Lawrenceville-Suwanee Road, likely due to high runoff and high flows on the small tributaries that flow into Little Suwanee Creek. Radar estimates indicate that localized amounts of 3 to 4 inches occurred in the area.
