What forecasters said that day

The local office's own words before this special weather statement went out, 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 this special weather statement went out at Aug 5, 3:25 PM EDT, 2 hours 24 minutes earlier.

Area forecast discussion, Aug 5, 3:25 PM EDT, 2 hours 24 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
325 PM EDT Wed Aug 5 2020

.SHORT TERM /Tonight through Thursday Night/...

Seeing fairly widespread convection popping up this afternoon, but
overall density of coverage remains somewhat sparse, and intensity
remains limited for now. Morning sounding showed a bit of a mid-
level cap and shallow lapse rates, but strong heating has not had
much trouble overcoming those limitations this afternoon. Still
likely to see some strong storms and cannot rule out a few isolated
damaging wind gusts. Convection expected to wane through the
overnight hours but atmosphere would support an isolated shower or
brief thunderstorm through most of the overnight period. Looks like
a repeat of this pattern tomorrow as the region remains under weak
southwesterly upper flow pattern with ample moisture and moderate
instability by midday with good surface heating.

20

.LONG TERM /Friday through Wednesday/...

Fairly typical summertime pattern for the extended portion of the
forecast.

An old frontal boundary across south-central/south GA will remain
nearly stationary through the weekend. This boundary may begin
pushing northward early next week, before dissipating. Near normal
temps/humidity for this time of year will lead to the
afternoon/evening development of showers and thunderstorms. The old
frontal boundary may provide for some focus, providing for slightly
higher pops in it's vicinity.

.AVIATION...
18Z Update...

VFR conditions will predominate across the forecast area for the
majority of the forecast period outside of isolated to scattered
convection. Areas of localized MVFR or lower conditions are possible
between 06Z and 14Z, with KAHN, KMCN, KCSG most likely TAF sites to
see some brief impacts. Winds will be mostly south to west 4-8kt
this afternoon, becoming light southeast to east after 00Z then
transition back to south to west 4-8kt after 14Z tomorrow. Scattered
afternoon and evening convection should peak in coverage around 21-
23Z then diminish to isolated at most after 02Z.

//ATL Confidence...18Z Update...

Medium to high.
