   Areas affected...West Virginia and far southwest Virginia

   Concerning...Severe potential...Watch possible 

   Valid 142230Z - 150000Z

   Probability of Watch Issuance...60 percent

   SUMMARY...A severe thunderstorm watch may be needed this evening.

   DISCUSSION...A line of storms has developed along a pre-frontal
   trough stretching from central Ohio into eastern Kentucky. The
   storms in southern Ohio and eastern Kentucky have mostly struggled
   up to this point as as surface dewpoints ahead of the storms have
   mixed into the low to mid 50s. This well mixed boundary layer will
   be supportive of damaging wind gusts from any stronger storms that
   can develop, but the very weak instability due to the meager surface
   moisture has made storm intensification difficult up to this point. 
   Very strong height falls are rapidly approaching this area and this
   additional synoptic ascent may aid with storm strengthening over the
   next few hours. This area will continue to be monitored for a
   potential watch. Given the relatively mixed boundary layer in this
   area and relatively veered surface flow compared to farther north,
   the predominant severe threat should be damaging wind gusts.
