   Areas affected...West Virginia...Northwestern Virginia

   Concerning...Severe potential...Watch possible 

   Valid 181043Z - 181245Z

   Probability of Watch Issuance...60 percent

   SUMMARY...A potential for severe wind gusts is expected to develop
   over much of West Virginia into northwestern Virginia this morning.
   Additional weather watch issuance may be needed.

   DISCUSSION...A severe MCS is currently ongoing near an axis of
   moderate instability located from central Kentucky
   east-northeastward into western West Virginia. The eastern edge of
   this instability is forecast to shift eastward across the remainder
   of West Virginia and into northwestern Virginia over the next few
   hours. This should be enough to maintain a severe threat with the
   eastern edge of an MCS as it moves into the central Appalachians.
   Just to the south of the MCS, the Jackson, Kentucky WSR-88D VWP has
   0-6 km shear near 70 knots. This will likely support an isolated
   severe threat, mainly with short bowing line segments. The primary
   threat will be damaging wind gusts, but an isolated tornado threat
   will also be possible.
