Mesoscale Discussion 0322
   NWS Storm Prediction Center Norman OK
   1140 AM CDT Wed Mar 23 2022

   Areas affected...Eastern Indiana and western Ohio

   Concerning...Severe potential...Watch possible 

   Valid 231640Z - 231845Z

   Probability of Watch Issuance...60 percent

   SUMMARY...A watch is possible for portions of eastern Indiana and
   western Ohio. Deepening convection will eventually support a threat
   for severe hail and isolated damaging winds.

   DISCUSSION...Showers have developed in parts of north-central
   Kentucky and southern Indiana over the last hour. Recent NLDN data
   shows a flash or two of lightning has occurred. With mostly clear
   skies ahead of this north/northeastward moving activity, these
   showers/storms are expected to deepen over the next couple of hours.
   As this occurs, strong effective shear (40-50 kts), 500-750 J/kg
   MLCAPE, and cold temperatures aloft will support a threat for severe
   hail. Low-level lapse rates will be steep enough to support a threat
   for isolated damaging winds as well. While the tornado threat will
   remain low, there is some potential for stretching of vorticity
   along the subtle confluence zone/surface trough this afternoon.
   Should this occur, a brief tornado would be possible. A watch is
   possible this afternoon.
