Areas affected...portions of middle Tennessee into north-central
Alabama

Concerning...Tornado Watch 715...

Valid 100218Z - 100345Z

The severe weather threat for Tornado Watch 715 continues.

SUMMARY...The severe threat continues across Tornado Watch 715.
Damaging gusts appear to be the main threat, though a tornado or two
cannot be ruled out over the next few hours.

DISCUSSION...Thunderstorms have consolidated into a QLCS across
middle TN into northern AL. Buoyancy continues to gradually wane
over the region, though impressive shear profiles remain (i.e. the
latest HTX VAD, which shows an elongated, curved hodograph). Given
the linear storm mode, damaging gusts should be the main threat as
the QLCS progresses across middle TN and northern AL (the remainder
of Tornado Watch 715). However, given the impressive shear profiles,
any portion of the line where a sustained mesovortex can develop may
support the development of a tornado.
