Strong daytime heating resulted in a moderately unstable atmosphere by late afternoon and evening across north Georgia. Thunderstorms developing along a stationary surface trough and enhanced by a weak mid-level short wave produced scattered reports of damaging thunderstorm wind gusts 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 14, 12:35 PM EST, 1 hour 13 minutes earlier.
Area Forecast Discussion...Updated for Aviation National Weather Service Peachtree City GA 135 PM EDT Wed Jun 14 2017 .SHORT TERM /Today through Thursday/... Latest surface analysis shows high pressure in control with ridge axis over central GA. A very light flow regime at the surface and aloft allowed for some very slow storm movement to the few storms we did see yesterday with 2 to 2 and half inches of rain for isolated locations. Activity long since dissipated with only sensible wx to worry about through daybreak is some low clouds for SW sections. Some mixed signals in the models today with parameter based analysis indicating a continued dry slot in mean rh from the southern metro through east Central GA. There is also a corresponding lack of instability in this zone with values only on the order of 200 to 300 J/KG with little to no rain chances. Contrast this with the hi res guidance which shows a majority of the afternoon activity for areas near Athens. For now...will lean toward the dry slot solution as this definitely played a role in the lack of activity for southern metro sections on Tuesday. Still humid across the Central portions with PWs approaching 2 inches once again and will carry high end chance pops there. Upper ridge begins to break down a bit on Thu with some mid level impulses approaching NW zones by afternoon. Dry slot still apparent over portions of the area but difficult to ascertain exactly where as narrow as it is. With high PW axis shifting northward along with aforementioned breakdown of the ridge...thinking we should see healthy pop values in the mid to high end chance range. This will be some 10 to 15 percent higher than guidance values. Deese .LONG TERM /Thursday Night through Tuesday/... The extended period remains largely unchanged and rather monotonous through about Monday. As we begin on Thursday night...the mid and upper levels will begin the process of taking on more weakly cyclonic flow regime in which multiple weak shortwave troughs will be advecting through. Stubborn weak trough stemming from a weak sfc low over the North Carolina Piedmont will also be lingering somewhere across eastern and northern Georgia. With such a pattern...think convection from Thursday will be slow to die down overnight into Friday. Cannot rule out some lingering strong to isolated severe in this timeframe...mainly associated with steeper mid level lapse rates as the cyclonic flow pattern builds in. On Friday...a very weak mid level shortwave will attempt to close off...or at least become more concentrated over the local area. This feature in conjunction with the Piedmont/lee side area of sfc low pressure in the vicinity should be plenty to spark numerous thunderstorms amidst a warm and unstable airmass. Coverage should increase quickly by Friday afternoon and linger into a good portion of Friday night. Weak low will continue to pump Gulf moisture into the CWA through Saturday so expecting Saturday to be similar to Friday...with perhaps slightly higher coverage across central Georgia as the low attempts to move S/SE...albeit very slowly. Same story for Sunday. By Monday...A strong shortwave will eject out of the Great Lakes into Ontario/Quebec. This will push the next cold front into the area...which should have no problem sustaining thunderstorm development along it despite best dynamics being well north. Belt of stronger westerlies remain far enough north to keep best shear out of the area. Things become a little unclear as this front progresses south through the CWA. At the moment...seeing anticyclonic flow around the Bermuda High pushing a plume of moisture into the region from the SE...which looks to collide with the front and create some sort of shear zone. Way too early to get cute with any details though. Still EC/GFS agreement on a tropical wave developing off the Yucatan next week. In addition...pattern change to Western US ridge and eastern US trough is possible by next week. Kovacik && AVIATION... 18Z UPDATE... Expect sct-bkn035-050 across the area this afternoon. Convection has started to develop and may affect all taf sites through the evening. Have added tempo across the KATL area sites due to activity approaching from the north. Otherwise wait and see for the remainder of the sites. Not looking for widespread morning stratus but may be sct clouds 030-040 around all night. Thursday generally a repeat of today but with better thunderstorm chances mainly north GA. Winds light WNW becoming light and variable overnight. //ATL CONFIDENCE...18Z UPDATE...
