An area of high pressure moved off the Atlantic Coast early on the 1st, with a weak frontal boundary stalled over the Ohio Valley. A convective system that developed along the stalled boundary dissipated during the day but was able to trigger isolated to scattered thunderstorm development across north Georgia during the afternoon hours.

The episode as NWS FFC wrote it up.
An area of high pressure moved off the Atlantic Coast early on the 1st, with a weak frontal boundary stalled over the Ohio Valley. A convective system that developed along the stalled boundary dissipated during the day but was able to trigger isolated to scattered thunderstorm development across north Georgia during the afternoon hours. One of these storms became severe with trees down.
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 Sep 1, 2:39 PM EST, 1 hour 6 minutes earlier.

PRECIP CHANCES CONTINUE ACROSS THE STATE MONDAY NIGHT BUT AS THE FRONT PUSHES TOWARD THE COAST TUESDAY AND TUESDAY NIGHT...DRIER AIR FILTERS IN BEHIND IT AND PUSHES PRECIP CHANCES INTO CENTRAL AND SOUTH GEORGIA. DRIEST DAY LOOKS TO BE WEDNESDAY AS THE TROUGH AXIS SHIFTS EAST OFF THE COAST AND HIGH PRESSURE DOMINATES MOST OF THE STATE. HOWEVER...ON THURSDAY ANOTHER SHORTWAVE ROUNDS THE BASE OF THE TROUGH AND LOOKS TO PROVIDE ENOUGH LIFT THAT WHEN COMBINED WITH OROGRAPHIC LIFTING IS ENOUGH TO WARRANT SLIGHT TO LOW CHANCE POPS IN THE NORTHEAST MOUNTAINS. ECMWF IS A LITTLE STRONGER WITH THIS SHORTWAVE INITIALLY BUT BOTH MODELS IN REASONABLE AGREEMENT WITH THIS FEATURE ON FRIDAY. AS WE PUSH INTO THE WEEKEND...THE GFS IS DEFINITELY THE WETTER OF THE TWO MODELS SO COMPROMISED ON THIS UNCERTAINTY BY PAINTING GENERALLY SLIGHT CHANCE POPS ACROSS THE AREA ON SATURDAY. AS FOR TEMPS...TUESDAY WILL CONTINUE THE TREND OF ABOVE-NORMAL TEMPS...AND EVEN WITH THE FRONTAL PASSAGE TEMPS WILL ONLY DROP A COUPLE OF DEGREES BUT SHOULD BE NEAR SEASONAL NORMALS. THE MORE NOTICEABLE CHANGE WILL BE IN OVERNIGHT LOWS...LIKELY DROPPING AT LEAST 5 DEGREES BETWEEN MONDAY NIGHT AND WEDNESDAY NIGHT.
