The radar

The Nashville radar (KOHX), 31 km from the middle of the area, began a volume at 00:35 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

Nashville Metro, TN (KBNA), launched 00:00Z, 0.6 hours before the alert went out and 43 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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, 6:15 PM CST, 19 minutes earlier.

Area forecast discussion, Nov 28, 6:15 PM CST, 19 minutes before

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

.UPDATE...
FOR EVENING DISCUSSION.

&&

.DISCUSSION...

Frontal boundary currently moving across western middle TN at this
time. The stronger line of convection extends from Cedar Hill to
ashland city through Iron City. Latest observations do indicate
that wind speeds have decreased back across the western TN area.
It is likely that this trend will continue and we will see wind
speeds decrease after the fropa and the stronger line of showers.
The back edge of the shower activity is in western TN and is
located about 30 miles west of the TN river.

The widespread precipitation should begin to end around 9 pm far
western areas, the i-65 corridor around 11 pm, and the eastern
most portions of the cwa around 4 am. Will be lowering pops from
west to east later in the shift.

will lean toward canceling the wind advisory for western areas in
the next hour or two. The advisory, however, is still in good
shape along and to the east of the boundary. Models do lean toward
a marked decrease in wind speeds by the 9 pm to 11 pm hour.

Otw, low dew point depressions are expected by sunrise. Could see
some lower vsbys due to fog late but not expecting vsbys to be
aob 1sm. Thus, for now, will keep the mention the fog out of the
fcst.

Remainder of fcst in good shape, will update the zones in an hour
or two as we see visual evidence of wind speeds backing off.

&&

.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.
