Aviation...

VFR conditions are expected through most of this 24-hour taf period.
A cold front will approach middle Tennessee late Thursday evening and may
throw a wrench in the VFR conditions. Showers and storms...some
strong...should approach the ckv and bna terminals by 02z and 04z
tomorrow night...respectively. Left thunderstorms in the vicinity/cumulonimbus in the tafs instead of
mentioning thunderstorms and rain...but for the last 3-6 hours of this taf
period...ckv and possibly bna should see storms with possible
strong wind gusts...as well as brief IFR/MVFR conditions.

Update...
temperatures trending ahead of schedule so have lowered overnight mins by
one to two degrees most areas. Could see pockets of lower 40s especially
in cold air drainage areas but think plateau and southeast middle
Tennessee have the best chance of the cooler temperatures. Surface ridge
axis down along eastern middle Tennessee with upper ridge from
Gulf region into Great Lakes. Plains system works this way on
Thursday. Should be late afternoon before we cloud up and Thursday
night before any showers and thunderstorms reach the middle state.

Have updated grids will send zones shortly.
