   Mesoscale Discussion 0835
   NWS Storm Prediction Center Norman OK
   0551 PM CDT Wed May 24 2017

   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.
