What forecasters said that day

The local office's own words before this river flood warning 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 river flood warning went out at Aug 3, 8:18 PM EDT, 34 minutes earlier.

Area forecast discussion, Aug 3, 8:18 PM EDT, 34 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
818 PM EDT Fri Aug 3 2018

.SHORT TERM /Tonight through Sunday Night/...

Showers and thunderstorms are ongoing in northeastern and
southeastern portions of our region, but are expected to dissipate
in the overnight hours. Some storms could produce locally heavy
rain, which could lead to some localized flooding concerns given
saturated soils from the rainfall from the last several days.
Upper level ridging is building into the southeastern CONUS to
begin the short term period, which is bringing about a return to a
more diurnally-driven pattern of convection to north and central
Georgia. This high pressure has allowed for drier air to build
into the forecast area today, however, moisture will again begin
to increase on Saturday. In spite of the increasing moisture, the
upper level ridge and associated surface high pressure system
should help to suppress convection tomorrow and keep showers and
thunderstorms more scattered in nature. Maintained chance PoPs for
Saturday afternoon and evening as a result. Due to the high
pressure inhibiting the rain chances and cloud coverage,
temperatures will be near normal values through the weekend.

King

.LONG TERM /Sunday through Saturday/...

No changes to the long term. GFS and ECMWF agree that high
pressure builds westward from the Atlantic across the forecast
area into the first of next week. This will produce a more diurnal
pattern of showers and thunderstorms. Toward the end of the period
another trough deepens over the OH Valley with an accompanying
short wave. So likely pops for the north still look okay. Previous
discussion is included below.

41

PREV DISCUSSION... /Issued 316 AM EDT Fri Aug 3 2018/

LONG TERM /Saturday through Thursday/...
A more diurnal pattern will begin to set up this
weekend into early next week as high pressure aloft and at the
surface builds in from the west. Pops and temps will trend towards
normal values.

Unfortunately, a wetter pattern may begin to set up again by the mid
to late part of the week as a frontal boundary approaches from the
north. This boundary is expected to approach by Thursday and
potentially move into north-central portions of the CWFA on Friday.

evening will weaken to nearly calm in the overnight hours and
