Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Nashville, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 23, 2:46 PM CDT, 3 hours 9 minutes earlier.

Area forecast discussion, Jun 23, 2:46 PM CDT, 3 hours 9 minutes before

Area Forecast Discussion
National Weather Service Nashville TN
246 PM CDT Sun Jun 23 2019

.DISCUSSION...

Scattered showers and thunderstorm have started to develop around
Middle TN at forecast time. A few of them could become strong with
gusts winds and small hail through about 6 pm.  However, this isn't
likely to be the show for today. Upstream, a more organized line of
showers and thunderstorms is expected to approach the TN River
around 7 pm. As they near Middle TN, they will be passing through an
instability axis that should top out around 3000 J/Kg due to
environmental temps in the low 90s and dew points in the low 70s. A
lack of shear and modest mid-level lapse rate around 6.5-7.0 deg/km
should keep most of this evening's activity below severe criteria.
However, I wouldn't be surprised to see a few storms west of I-65
with some damaging wind gusts. By the time storms reach I-65 (maybe
just east of there), they should begin losing their punch. I have
illustrated this with PoPs falling off in the east prior to midnight.

Around sunrise tomorrow, yet another system should be knocking on
our door. This is likely going to be more synoptically driven
(versus diurnal in nature), which is why we'll run the risk of at
least some strong storms as early as mid-morning. Showers and
thunderstorms associated with this system will press eastward
through the late morning and early afternoon hours and as they do,
we'll run a slightly better chance of strong to severe storms east
of I-65, especially in the afternoon. Once again, damaging winds
will be the main threat. If there's any silver lining to tomorrow,
models are consistently showing this thunderstorm development
getting east of the Cumberland Plateau prior to 7 pm.

The passage of tomorrow's storms will signal an overall pattern
change. While we won't run into a stretch of days where we're dry,
at least we should be looking at more of a diurnal trend to
thunderstorms, much more summer-like in nature, bringing an end to
what seems to be an endless string of MCSs. On the downside, this
pattern change will come with temperatures much more summerish, too.
Highs in the low 90s will return on a regular basis, fueling those
afternoon/early evening thunderstorm chances each day this week.

&&

.AVIATION...
18Z TAF DISCUSSION.

An isolated afternoon storms cannot be ruled out this afternoon
ahead of a complex of storms moving of storms moving in from
western Tennessee this evening. That system will be falling apart
as it heads towards BNA and MQY. Those storms will likely not
reach CSV. If a terminal is impacted, visibilities will be reduced
to MVFR/IFR. More storms will likely develop as a front moves
through west to east after 12z. Winds will pick up out of the SSW
after 24/14z to 10 kts with gusts to 20 kts.
