   Areas affected...Central/Eastern OH...Northwest WV...Northern WV
   Panhandle

   Concerning...Severe potential...Watch unlikely 

   Valid 261804Z - 262000Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated hail and/or strong wind gusts possible for the
   next hour or two.

   DISCUSSION...A cluster of strong multicellular thunderstorms has
   recently developed over central OH, in an area of modest moisture
   convergence near a remnant frontal boundary and ahead of an outflow
   boundary approaching from the north. These storms have developed
   along the southern periphery of the strong mid-level flow and over
   the eastern periphery of an area of moderate instability. Given its
   displacement from both the better vertical shear and stronger
   instability, the longevity of these storms is uncertain.
   Additionally, the downstream environment is also characterized by
   lower temperatures and dewpoints and weaker instability, casting
   further doubt to storm persistence. 

   Even with these uncertainties, the current storm structures reveal
   strong updrafts and enough overlap between instability and vertical
   shear exists to support hail and/or damaging wind gusts.
