Mesoscale Discussion 0191

   Areas affected...Western OH into central/southern IN and central KY

   Concerning...Severe potential...Tornado Watch likely 

   Valid 150609Z - 150745Z

   Probability of Watch Issuance...80 percent

   SUMMARY...Broken band of severe storms will spread east of the
   current tornado watches, with the potential for a new watch by 07z
   from western OH into southern IN and central KY.

   DISCUSSION...A broken band of supercells with a history of tornadoes
   and damaging winds will continue to spread eastward through the
   early morning hours.  70-80 kt south-southwesterly flow in the
   lowest 2 km AGL, sampled by regional VWPs, will support continued
   moistening near and just above the surface, in advance of the
   ongoing convection.  Though buoyancy will be weaker with time and
   eastward extent and storm mode should evolve into more line segments
   and clusters, destabilization should remain sufficient for a threat
   for wind damage and a few tornadoes.  A new tornado watch will
   likely need to be considered for areas from southern IN and western
   OH into central KY by roughly 07z.
