.DISCUSSION...

Weak region of pva now traversing the Cumberland Plateau.
Scattered showers now covers that area. Will opt to bump morning
pops up to 30 percent. Otw, a stronger shortwave is expected to
move into position from the west later this afternoon. Current
forecast on track as pops will increase by late afternoon. Hrrr
not overly aggressive with the convective development but the
shortwave looks rather potent. Temps appear to be on track for
now, heat advisory continues for roughly the eastern two thirds of
the mid state.

.AVIATION...
12Z TAF DISCUSSION.

A cold front will drop slowly southward across Kentucky through
the forecast period. Scattered showers and thunderstorms are
expected to develop over northern Middle Tennessee by late this
afternoon, with scattered activity likely to continue into the
overnight hours as well. Outside of showers and storms, expect VFR
conditions through 10z. However, in precipitation areas conditions
may deteriorate to MVFR, and perhaps briefly to IFR conditions.
After 10z, patchy fog is possible, especially in areas that
receive rain later today and tonight.
