Areas affected...South-Central KY...Northern Middle TN

Concerning...Tornado Watch 25...

Valid 221526Z - 221730Z

The severe weather threat for Tornado Watch 25 continues.

SUMMARY...Isolated damaging wind gusts may occur across portions of
south-central KY and northern Middle TN.

DISCUSSION...A line of thunderstorms currently extends from far
south-central KY southwestward through northern middle TN and back
into western TN. The northern portion of this line has shown a trend
for a bit more forward motion as updrafts/downdrafts within the line
briefly intensify. This has lead to a few inflections within the
line, indicative of slightly stronger winds possibly reaching the
surface. Storm motion is already fast (i.e. around 50-55 kt) so any
convective augmentation could lead to isolated severe gusts reaching
the surface. Even so, stable boundary layer sampled by the 12Z BNA
is likely limiting the overall realization of stronger winds at the
surface. The overall trends of updrafts intensifying briefly within
the line may continue, but the low-level stability will likely
persist, limiting the overall severe potential with eastern extent.
