National Weather Service Nashville TN
936 PM CDT Wed Jun 19 2019

.UPDATE...
FOR EVENING DISCUSSION.

&&

.DISCUSSION...

Area of storms and showers continues to push east and slightly
southward. We have seen the southwestern tail weaken over the last
hour, but some pockets of strong winds are still possible for
areas east of I-65. After midnight additional storms may push into
the mid-state from the west as a mid level trough moves closer
and provides some overnight lift. This activity should be slightly
weaker with less coverage than we saw this evening. However, with
some instability still available overnight and models indicating a
slight uptick in bulk shear, strong wind gusts and a few
organized strong or severe storms will remain a possibility. So
keep the weather radios on and phones nearby just in case. Updated
pops and weather grids to reflect the continued overnight storms.
Will gradually remove counties from the Severe Thunderstorm Watch
as storms push east.

&&

.AVIATION...
00Z TAF DISCUSSION.

The next 12 to 16 hours will bring intermittent thunderstorms and
showers to all sites. Some storms may be strong or severe and will
bring strong winds, reduced visibilities, and low cigs to sites as
they pass by. There will be some periods of MVFR to VFR
conditions between waves of storms. Thursday will bring improving
conditions as a final wave of scattered storms sweeps through the
area and off the Plateau by early afternoon.
