   Mesoscale Discussion 0751
   NWS Storm Prediction Center Norman OK

   Areas affected...Portions of upper Ohio Valley

   Concerning...Severe potential...Watch unlikely 

   Valid 111837Z - 112030Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Isolated small to marginally severe hail and damaging
   winds are possible with the strongest storms in the upper Ohio
   Valley. A watch is not expected this afternoon.

   DISCUSSION...In the wake of morning showers, temperatures have
   recovered into the mid/upper 50s F in eastern Ohio into northern
   West Virginia. Convection is developing along the cold front with
   aid from the compact shortwave trough moving through the lower Great
   Lakes region. Buoyancy will be limited, particularly near the
   Ohio/Pennsylvania border where stable outflow is apparent on visible
   satellite. An area of broader clearing near the southeast Ohio/West
   Virginia border should provide the greatest potential for storms to
   deepen sufficiently to produce marginally severe hail and isolated
   damaging wind gusts.
