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.

Area forecast discussion, Jun 4, 10:14 AM CDT, 1 hour 48 minutes before
Area Forecast Discussion
National Weather Service Nashville TN
1014 AM CDT SAT JUN 4 2016

.UPDATE...
FOR MORNING DISCUSSION.

&&

.DISCUSSION...

Showers with a few rumbles of thunder have been popping up across
the mid state this morning. All of this activity has remained
below severe thresholds and is expected to stay that way until at
least noon. Radar is estimating around 0.5 to 0.75 inches of
rain fell with the showers that are currently moving across areas
south and east of Nashville. The potential for localized flooding
will be higher in those areas as we approach the afternoon and
precip coverage increases. With ample moisture and very little
convective inhibition in place, it shouldn't take much for strong
to severe storms to develop this afternoon. The main threats will
be isolated flooding, damaging winds, and hail. No major changes
were made to the previous forecast.

&&

.AVIATION...
12Z TAF DISCUSSION.

Other then some light fog at KCSV/KCKV, VFR flight conditions at
forecast time. This is expected to continue through most of this
TAF cycle. Scattered TS are likely this afternoon, but will cover
with VCTS until next set of TAFs to try and time out activity
better. Either way, if flight categories fall, it will be short
lived.

More widespread showers and a few thunderstorms are more likely
tonight, especially after 03Z for all 3 terminals. Have prevailed
RA, but might need to add in TS if they are more than just
scattered tonight.

Winds will be light, with mainly a southwesterly component.

&&

.OHX WATCHES/WARNINGS/ADVISORIES...
NONE.
