The episode as NWS FFC wrote it up.
Strong daytime heating and moderate instability resulted in scattered strong thunderstorms, and an isolated severe thunderstorm, across north Georgia.
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 Jun 12, 2:31 PM EST, 1 hour 14 minutes earlier.
Area Forecast Discussion National Weather Service Peachtree City GA 331 PM EDT Mon Jun 12 2017 .SHORT TERM /Tonight through Tuesday Night/... A deep moist southerly flow continues over the area today as a weak short wave drifts around the northern Gulf. The eastern sections of the forecast area remained a bit drier as high pressure extended westward from the Carolinas. This pattern is expected to change little through the short term. The most likely areas of convection remain the western and central zones and capes and lifted index values generally show this trend. Expect the thunderstorms to diminish after sunset and have included no pops after 06z...however would not be surprised to see a few showers last all night. Forecast high temperatures are running near to slightly below normal for Tuesday. Forecast low temperatures are running slightly above normal due to clouds and moist air mass. 41 .LONG TERM /Wednesday through Monday/... Still not seeing any significant changes to make to the previous trends of a warm and relatively wet forecast through the extended forecast period. Weak upper troughing and a weak but persistent surface boundary across the forecast area will result in best coverage of diurnally oriented convection over the forecast area during the latter half of the work week and into the weekend. Although mid-level lapse rates and instability are moderate through this time frame, lack of any strong forcing and shear points to only a handful of strong to maybe a few isolated, marginally severe, storms each afternoon/evening. Temperatures will continue at or a bit above seasonal normals through the period. Please see the previous Long Term Forecast Discussion below. 20 Previous LONG TERM Forecast Discussion /Tuesday Night through Sunday/... Typical summer pattern expected through the extended period. As we begin on Tuesday night...will see a weak...yet somewhat messy ridge pattern across the eastern 2/3rds of the country as a closed low emerges out of the northern Rockies into the Northern Plains and carries on a negative tilt. Associated sfc reflection will move north from North Dakota into southern Canada...taking with it any hope for a change in airmass across our neck of the woods. As we go into Wednesday...plentiful moisture will be place underneath a decaying mid level ridge. Although Bermuda sfc ridging will still be in place...a trough stemming from a cyclone across far eastern Canada will extend all the way down the Eastern Seaboard into Georgia. Although models show somewhat lower PW values and QPF in the vicinity of this boundary...still think this feature will help focus POPs by afternoon. Think large majority of the activity will be diurnally driven. As the Canadian cyclone continue its eastward trek...trough feature looks to still linger as a weak sfc low develops over the Carolina Piedmont. This Piedmont trough will likely persist through most of Friday and with the de-amplification of the mid level ridge...think thunderstorm coverage will be highest these days. Pattern looks to transition to weakly cyclonic late Friday into the weekend. Numerous shortwave troughs migrating through this flow will spark thunderstorm activity all the way through the remainder of the extended...especially in the afternoon with the humid airmass remaining stagnant. Kovacik && AVIATION... 18Z Update... Variable ceilings should continue due to showers and thunderstorms but should average around bkn030-040. Thunderstorms should affect all taf sites but KAHN appears to have the lowest chance for now. Expect convection to diminish some after sunset. Surface winds SSE less than 10 kts and light and variable overnight. //ATL Confidence...18Z Update... Medium confidence for on all elements. 41 && .PRELIMINARY POINT TEMPS/POPS...
