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 Jul 21, 12:09 AM CDT, 2 hours 29 minutes earlier.

Area Forecast Discussion
National Weather Service Nashville TN
1209 AM CDT Sat Jul 21 2018

.UPDATE...
FOR 06Z AVIATION DISCUSSION.

&&

.DISCUSSION...

Per current radar trends and consensus of short term models, will
curtail any potential of rounds of shwrs/tstms to generally the
Upper Cumberland Region overnight. Most of the rest of the mid
state will have a chance of showers and thunderstorms thru the
early morning hours. Although not a lot of upstream convection
noted, especially to our northwest presently, it is still just so
unstable with copious moisture, that if a weak upper level
disturbance can provide at least some marginal lift as it
approaches and moves across the mid state region, sct shwrs and
tstms could still develop to our northwest and move thru the mid
state region overnight. So, even though there is little if any
activity at this point upstream and skies across a good portion of
the mid state are fair to clear presently, will continue to
mention the possibility of a chance of showers and thunderstorms
across most of the mid state region. Tweaked hrly temp, dewpoint,
and wind speed/direction grids. Adjusted toward sunrise the
morning hours the coverage of shwrs/tstms decreasing their
coverage as sunrise approaches. Current temperature trends
without the expected rainfall this evening are much warmer
than previously expected, and thus will raise overnight
lows by several degrees. As of this time, remainder of forecast
continues to be on track. Will thus be updating the suite of
forecast products shortly.

&&

.AVIATION...
06Z TAF DISCUSSION.

CKV/BNA/MQY/CSV...It looks like CSV will have the best chance of
experiencing a round of shwrs/tstms, and will break out a tempo
group to address this possibility. Will mention MVFR ceilings
and IFR vsbys with this TEMPO group. Otherwise, even with clr
skies and not much of activity noted to our northwest, still
can not rule out at least in the vcnty shwrs/tstms at the other
terminals at least thru 21/10Z. It still appears that another
round of shwrs/tstms could develop 21/18Z-22/02Z. However,
uncertainty still exist for actual location development at
terminals, but can not rule out in vcnty, and thus mentioned.
