Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

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

FOR MESOSCALE DISCUSSION...

.MESOSCALE DISCUSSION...

At 1235 AM CDT, showers and scattered thunderstorms were
occurring across Mid TN, with severe.tornadic thunderstorms south
of our area along the AL/MS line. Over the next couple of hours,
the severe storms along with a warm front will lift up into our
southern counties. Wayne, Lawrence, and Giles Counties should be
prepared for at least severe warnings soon. Tornado warnings may
be needed, especially if the long track supercell in
Colbert/Franklin Counties in Alabama holds together.

Through the very late night hours into the early morning, the
main severe threat will continue to lift northeastward across
Shelbyville, Manchester, McMinnville, Altamont, Spencer,
Crossville and surrounding areas. It looks like threatening
conditions will last for these areas until 9 or 10 AM CDT.
Farther northwest (including Nashville), the threat is lower. In
fact, it now looks like our northwest counties have a very low
threat for severe storms.

After this late night and early morning wave of storms across
mainly the southeast half of our area, there will be very low
potential for any more severe development. It is doubtful the
atmosphere will have time to "reload" after this first wave before
the arrival of the cold front. If additional storms do develop,
it will be briefly over the Plateau around midday before the focus
for storms moves off well to our east.

&&

.AVIATION...
06Z TAF DISCUSSION.

BNA/MQY/CKV/CSV...A broad area of rain with embedded
thunderstorms is moving across Middle Tennessee early this
morning. Also, significant LLWS can be expected for the next
several hours owing to an unusually strong low-level jet. Look for
TEMPO low ceilings & vsby as these cells move across the mid
state. The back edge of the activity is expected to move through
prior to 12Z, with the exception of CSV, which will be a couple
hours later. Afterwards, there is very little chance of additional
cell development as a dry slot gets pulled into Middle Tennessee
while the surface low moves very close to our north. Look for
winds to increase significantly during the day Sunday before and
after the surface fropa. There may be some MVFR ceilings during
the late afternoon and early evening as occluded front moisture
passes over.
