Areas affected...Portions of eastern Kentucky and far western
Virginia

Concerning...Tornado Watch 264...

Valid 242251Z - 242315Z

The severe weather threat for Tornado Watch 264 continues.

SUMMARY...A brief tornado remains possible near far northern
portions of Watch 264.

DISCUSSION...As cells interact with a warm front across northeastern
Kentucky, backed surface flow and enhanced low-level storm-relative
helicity will continue to provide a small window for a brief
tornado. However, with weak/modest residual surface-based buoyancy
and the onset of nocturnal cooling, convective intensity should
remain marginal across eastern portions of the watch. As such, while
a small threat persists, it is unlikely to extend far downstream
(northeast) of the ongoing watch.
