Areas affected...from southern Ohio across Kentucky and into Middle
to western Tennessee

Concerning...Tornado and Severe Thunderstorm Watches 165...167...

Valid 280600Z - 280800Z

The severe weather threat for Tornado and Severe Thunderstorm
Watches 165, 167 continues.

SUMMARY...A risk of tornadoes persist from northeast Arkansas into
Middle Tennessee and western Kentucky, with transition to damaging
wind into eastern Kentucky and southern Ohio.

DISCUSSION...A linear structure with damaging gusts and QLCS tornado
risk currently extends from the OH/KY border southwestward across
much of northern Kentucky. Instability drops off rapidly with
eastward extent, and the need for additional watches there is
uncertain.=20

Farther southwest, supercells are ongoing over much of Middle TN,
near the eastern edge of the stronger instability. Shear remains
quite favorable for supercells and tornadoes with effective values
over 400-500 m2/s2. The tornado risk may extend a bit outside/east
of TOR #0167, and a local expansion may be needed.

Otherwise, the strongest combination of instability currently
extends from far western KY/TN into AR. Although these cells have
generally merged into a line, periodic supercell tornado risk will
remain possible, especially with any rightward moving embedded
cells.
