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 31, 3:50 PM EDT, 3 hours 20 minutes earlier.

Area forecast discussion, Aug 31, 3:50 PM EDT, 3 hours 20 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
350 PM EDT Tue Aug 31 2021

.SHORT TERM /Tonight through Wednesday Night/...

Remnants of Ida circulating over the TN Valley this afternoon and
should drift northeast along the Appalachians overnight. Showers and
thunderstorms should gradually diminish during the evening but
will keep pops overnight...with highest pops lingering northeast.
As the remnant low moves into the central Appalachians on
Wednesday...decreasing shear and instability should support only
slight chance/chance pops for much of the area. Increasing northwest
flow aloft should help the forecast area dry out somewhat for
Wednesday night...so have pops diminishing to less than 20 percent
across the area. Radar trends show a temporary break for much of the
area this afternoon...but stronger convection development seems to
limited at this time. The Flash Flood Watch has been left as is.

41

.LONG TERM /Thursday through Tuesday/...

By Thursday morning, the trough associated with the remnants of Ida
has shifted off to our north and east and taken any remaining
tropical moisture with it. A comparatively much drier airmass pushes
south and overspreads our area by Friday as the fringes of an upper-
level ridge centered over the Great Plains edges further eastward.
PWATs drop to as low as 0-60-0.70", in the lowest 10%
climatologically for this time of year. PoPs are effectively effaced
as the ridge continues to broaden, preserving the bubble of dry air
over the southeast US. We remain in a subsequent regime of northwest
flow for the remainder of the week and throughout the weekend.

Beginning early Sunday, models hint at a moisture gradient/frontal
boundary advecting into CWA from the northeast. The Euro favors a
stronger, more persistent gradient, while the GFS tapers its
influence off more quickly before dissipating early Monday morning.
As a result, slight to low-end chance PoPs filter back into the
forecast for the start of the work week.
