Areas affected...Middle Tennessee and northern Alabama

Concerning...Tornado Watch 59...

Valid 160354Z - 160600Z

The severe weather threat for Tornado Watch 59 continues.

SUMMARY...Severe threat continues within WW59.

DISCUSSION...A squall line continues eastward across Middle
Tennessee, with history of damaging winds and hail. A cluster ahead
of the main line of thunderstorms has exhibited occasional strong
rotation and will likely merge with the main line over the next
hour. Though moisture remains more marginal, with dew points in the
low to mid 50s F and MLCAPE around 250-500 J/kg. Strongly sheared
profiles (as observed from the VAD at KBNA) continue to support a
strong line of thunderstorms with embedded mesovorticies and
potential for damaging wind and tornadoes over the next several
hours.
