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 Jun 18, 3:38 PM EDT, 37 minutes earlier.

Area forecast discussion, Jun 18, 3:38 PM EDT, 37 minutes before
Area Forecast Discussion
National Weather Service Peachtree City GA
338 PM EDT Tue Jun 18 2019

.SHORT TERM /Tonight through Wednesday Night/...
Current radar loop shows showers and thunderstorms moving NE
across the area this afternoon. We just issued our first severe
thunderstorm warning and with the way things are progressing this
will mostly likely not be the last one today. The current
marginal risk across North and Central GA still looks good
especially with instability developing and the showers and
thunderstorms becoming more numerous. These showers and
thunderstorms are associated with a strong shortwave that moved
east out of the Mississippi river valley overnight and is now
pushing across the local area. The forecast models continue to
indicate a decent amount of instability this afternoon. Current
Mesoanalysis shows surface based capes in the 1500 to 2500 J/KG
range with LIs in the -4 to -5 range across the state. This will
definitely help with developing some severe storms with the
greatest threats being strong gusty winds and hail. PWs are also
in the 1.8in to 2.0in range so looking for periods of heavy rain
as well. This shortwave will continue to push east overnight with
some slightly drier air working in by mid morning Wednesday. Will
still keep chance pops in as some embedded followup shortwaves
move through but overall, activity should be less than today.
Abundant cloud cover will keep temps in check with low to mid 80s
for the North but still getting to the 90s degree mark for Central
GA.

01

.LONG TERM /Thursday through Tuesday/...
No major changes needed for the forecast.

500mb trough will continue moving out of the CWFA Thursday night
with NW flow aloft setting up briefly. 500mb high pressure center
sets up in the GOMEX, with the CWFA on the periphery of the ridging
in a prime position to be impacted by shortwaves in the flow. The
models are hinting at some potential for a MCS on Saturday. Another
500mb trough may impact the SE states early next week.

At the surface, a weak surface boundary will slip south over the
CWFA on Thursday. Some question on how far south the boundary will
make it before pushing back north as a warm front during the weekend.
The CWFA will remain in the warm sector into next week, with a lee
trough noted in the pattern.
