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 Apr 20, 3:22 PM EDT, 38 minutes earlier.

Area forecast discussion, Apr 20, 3:22 PM EDT, 38 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
322 PM EDT Sat Apr 20 2019

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

Closed upper low circulating over the southern Appalachians will
gradually drift northeast overnight. Associated cloud shield should
diminish and also pull to the northeast...but may take much of the
afternoon and evening to improve across the area. The back edge of
the showers seem to be progressive and have just about cleared west
of Rome to Atlanta. After a cold night tonight...there will be a
warming trend Sunday and Sunday night as the upper ridge builds
across the southeast. Winds may gust some tomorrow but not as much
as today.

41

.LONG TERM /Monday through Saturday/...

Only minor tweeks to the precipitation chances later next week,
otherwise the previous long term forecast looks on point.

At the start of the long term forecast on Monday upper-level ridging
and a surface high pressure centered to the east will help to keep
the area dry with above average temperatures until Thursday.

Low-resolution models beyond are coming closer to agreement than
before but have major discrepancies with the development of a
surface low-pressure system along the gulf. Both the GFS and Euro
have upper-level cutoff low-pressure systems that primarily rejoins
the subtropical jet stream. The Euro solution transitions quickly
into a positively tilted trough with strong dynamic support for a
surface low-pressure system developing along the baroclinic Gulf
coast bringing a strong storm system through the forecast area on
Friday. Afterwards, high pressure returns to the area. The GFS on
the other hand, keeps a very weak upper-level cutoff low over the
Gulf states after feeding most of its energy back into the main jet,
and as a result, doesn't develop the same surface low-pressure
system. Instead it keeps the area in broad Gulf flow with storms
forming around an extended stationary front oriented horizontally
across the state from Thursday night through the end of the extended
period. Though the hope is on the former solution, it remains to be
seen which one of these solutions will verify at this time. For now,
mostly chance POPs for the back half of next week and we'll hold our
breath in anticipation.

Thiem

PREV DISCUSSION... /Issued 335 AM EDT Sat Apr 20 2019/

LONG TERM /Sunday Night through Friday/...
Dry weather is expected through Tuesday.

GFS and European are not too consistent with just the GFS indicating
some moisture skirting far n GA Wednesday/Wednesday night with
only small chances for light showers.
The GFS is much wetter on Thursday with the rain chances exiting
on Friday while the European is dry on Thursday and brings in the
moisture on Friday. This is mainly due to the European starting with
a closed low at 500mb and the GFS is indicating a more open wave.
Instability is somewhat limited but thunderstorms will certainly be
possible Thursday and Friday.

BDL

AVIATION...
18Z Update... MVFR ceilings across the area will continue to improve
to VFR through the late afternoon and early evening. Light showers
over the taf sites will gradually push eastward through 00z. Winds
will be west near 10kts with gusts to 20kts possible through 00z and
diminishing after that.

//ATL Confidence...18Z Update... Medium to high confidence all
elements.
