   Areas affected...southwest Ohio into eastern Kentucky and West
   Virginia

   Concerning...Severe potential...Watch unlikely 

   Valid 170556Z - 170830Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A cluster of storms will likely persist tonight as it
   moves out of Ohio and into eastern Kentucky and West Virginia.
   Marginal hail or a locally gusty winds are expected

   DISCUSSION...As of 06Z, a cluster of storms exists over northern IN
   and western OH, in a zone of theta-e advection from the west. These
   storms have been expanding in coverage overall, with sporadic small
   hail cores. Given the orientation of winds aloft, this cluster is
   likely to turn southeast as it continues into KY and WV. The western
   fringe of this activity in closer proximity to the stronger
   instability may be capable of occasional marginal hail. The boundary
   layer will be relatively cool but if the cluster organizes, strong
   wind gusts will be possible. Eastern portions of the system are
   unlikely to pose any hazards, being farther away from the
   instability source from the west.
