Areas affected...Eastern KY/TN into southwest WV/western VA

Concerning...Severe Thunderstorm Watch 681...

Valid 242252Z - 250045Z

The severe weather threat for Severe Thunderstorm Watch 681
continues.

SUMMARY...Some hail/wind threat continues with scattered storms this
evening.

DISCUSSION...Short-wave trough is ejecting across the OH Valley
early this evening and scattered strong/severe convection continues
within the warm-advection zone, well ahead of the front. Over the
last few hours, greatest concentration of robust, long-lived
updrafts/supercells is beneath the strongest mid-level flow across
eastern KY/northeast TN. Radar data suggests at least 4-6
supercells, extending 50mi either side of the TN/KY border, moving
east-northeast toward western VA/southwest WV. However, air mass is
notably less buoyant downstream and these updrafts will encounter
increasingly hostile environment across the higher terrain and
points east. Until then, hail/wind threat will continue with these
storms.
