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 May 11, 7:54 AM EDT, 2 hours 34 minutes earlier.

Area forecast discussion, May 11, 7:54 AM EDT, 2 hours 34 minutes before

Area Forecast Discussion
National Weather Service Peachtree City GA
754 AM EDT Sat May 11 2019

.UPDATE...

&&

.PREV DISCUSSION... /Issued 450 AM EDT Sat May 11 2019/

SHORT TERM /Today through Sunday/...

To begin the short term period, the forecast area remains underneath
persistent southwesterly flow aloft. A shortwave embedded within the
flow is moving northeastward from south Mississippi and towards
Georgia. Thunderstorms out ahead of this disturbance have been
moving across north Georgia during the overnight hours and another
round is currently entering into the northwest corner of the CWA.
Some thunderstorms associated with this line may be strong and could
be capable of producing gusty winds, frequent lightning, and small,
sub-severe criteria hail. PoPs will remain categorical across far
north Georgia during the morning and through the rest of the day
Saturday, and likely PoPs will also build in across central Georgia
starting around mid-morning as thunderstorms redevelop across the
area.

MLCAPE values are expected to peak around 2000 J/kg this afternoon.
Sufficient deep shear will also be in place during this time to
support some organized convection as the upper-level shortwave
approaches the area, although a focused lifting mechanism will be
lacking which will limit how organized the storms will be. At this
time, the primary severe threat appears to be damaging wind gusts,
although some large hail is also possible with some isolated storms.
PWATs across the area will be in the 1.3 to 1.7 range, and the axis
of the heaviest precipitation is expected to be along and north of
the I-85 corridor. The highest totals are anticipated in the higher
elevations of the far northeast, where 2-3 inches are possible
throughout Saturday. The airmass will remain moist and summer-like
throughout the day on Sunday. Models are furthermore indicating
another strong mid/upper level disturbance and associated surface
front moving through the area throughout the day on Sunday, which
will bring categorical PoPs across the area. With moderate
instability and increased deep-layer shear, there is once again the
potential for some thunderstorms to be strong to severe on Sunday.

King

LONG TERM /Sunday Night through Friday/...

Aside from the departing frontal system that stalls near the
extreme southern part of the CWA late Sunday into Monday with
lingering low end pops for showers or storms, the majority of the
fcst period looks to be benign and ridge dominated. A weak upper
wave and attendant backdoor sfc front could bring a slight chance
of showers or storms to north GA late Wednesday into Thursday,
though guidance still has some timing and moisture discrepancies.

Min temps will actually be rather cool in the upper 40s to low
50s for most areas Monday through Wednesday, then moderate back
to near or slightly above normal for the end of the work week.

.AVIATION...
12Z Update...
Showers and thunderstorms are ongoing across far northern Georgia
but are staying away from any TAF sites. Precipitation chances are
expected to build southward during the late morning and early
afternoon with -SHRA arriving at most sites by 17-18Z and
remaining through the rest of the period. Thunder is also possible
throughout the day today, with the most active period for -TSRA
being between 20Z and 00Z. Low IFR stratus is in place to start
the period and is expected to improve to MVFR by 14Z and further
to VFR this afternoon. Winds have shifted to SW and will remain so
through the remainder of the period at 5-10 kts, with the
exception of any thunderstorm outflows that occur.

//ATL Confidence...12Z Update...
