The episode as NWS FFC wrote it up.
A series of northwest flow short waves continued to impact the area, supported by a persistent strong subtropical ridge over Texas and an upper trough in the northeast United States. An overnight mesoscale convective system (MCS) across the western Tennessee Valley, supported by one of these short waves, moved into northern Alabama during the morning hours of the 17th, then southeast into west central Georgia during the early and mid-afternoon. Although the system was in a diminishing state, it remained organized and intense enough to produce damaging winds across west and into central Georgia as it move southeast through the afternoon.
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 17, 12:58 PM EST, 1 hour 5 minutes earlier.
