Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this severe thunderstorm warning; the first came 14 minutes after it went out.

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 Nov 28, 1:32 PM CST, 4 hours 29 minutes earlier.

Area forecast discussion, Nov 28, 1:32 PM CST, 4 hours 29 minutes before

Area Forecast Discussion
National Weather Service Nashville TN
132 PM CST Mon Nov 28 2016

.DISCUSSION...

Deep cyclone centered over western Minnesota this aftenoon will
undergo an occlusion next 12 to 24 hours with occluded front
swinging across our area later tonight preceded by large area of
much needed showers this afternoon and tonight that will include
some thunderstorm activity as it moves through our area. Models
develop a narrow embedded line of convection (QLCS) far eastern
Arkansas around 19z and work it to just east of Memphis by 21z and
nearing the Tennessee River around 23z and to interstate 65 about
02z. Once line gets east of interstate 65 it begins to weaken.
Buoyancy looks weak to me but strong low level shear in
association with strong low level jet is enough for concern that
storms could drag jet down to the ground. Also looking at shear
profiles on hodographs along with helicity swaths, think area of
greatest concern would be in a corridor along and south of
interstate 40 into the Nashville area. This would include Linden,
Waynesboro, Hohenwald, Columbia, Centerville, Franklin and
Nashville. Weakening occurs once QLCS gets east of interstate 65.
Occluded front sweeps rain to our east rather quickly after
midnight and off the plateau around daybreak Tuesday. Basically
dry Tuesday but another round of rain will move into Middle
Tennessee Tuesday night and Wednesday morning as secondary system
moves into the area from Oklahoma. Looks like another good chance
of rain coming over the weekend.

Temperature wise I don't see a major change in our temps over the
next 7 days.

Rainfall over the next 3 days could total 1.5 inches across the
north to possibly 3 inches near the Alabama border and in
southeastern Middle Tennessee down through Grundy county as Middle
Tennessee will be affected by two storm systems.

&&

.AVIATION...
18Z TAF DISCUSSION.

Strong pre-frontal trough expected to push across the Mississippi
Valley this afternoon, and across western and middle Tennessee
overnight. Strong winds will occur ahead of the trough, and have
left mention of low-level wind shear in the CKV and BNA TAFs for
this evening.

VFR conditions will give way to occasional MVFR conditions late
this afternoon and overnight, mainly in a relatively narrow band
ahead of the front. After the front passes, conditions are
forecast to return rather quickly to VFR, with southwest surface
winds becoming gusty on Tuesday ahead of a cold front, which will
be moving out of the Plains into the Mississippi Valley. Gusts of
20 to 25 mph will likely be common by Tuesday afternoon.
