.DISCUSSION...

Updated suite of forecast products to mention tornado watch 64 for
Perry and Wayne Counties until 4 AM CDT Sunday. Tornado watch
59 expired for other selected counties across southern Middle
Tennessee as of 9 PM CDT. Tweaked hourly temperature, dewpoint,
and wind speed/ direction grids and blended them with associated
forecasted late evening through overnight hours.

&&

.AVIATION...
06Z TAF DISCUSSION.

Showers and strong to potentially severe thunderstorms will move
across the taf areas over the next few hours. CKV, however, looks
as though it will remain west of the heaviest activity as it
continues to move east and away from that taf site. Otw, the
thunderstorm threat looks as though it will finally end around 09Z
for BNA and MQY...and 11Z for CSV. The rain should end area wide
by 14Z, with partial clearing to follow.
