   Mesoscale Discussion 0827
   NWS Storm Prediction Center Norman OK
   1047 AM CDT Wed May 24 2017

   Areas affected...Portions of eastern Indiana and western Ohio

   Concerning...Severe potential...Watch unlikely 

   Valid 241547Z - 241645Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Scattered thunderstorms are developing in the discussion
   area at this time and may pose a very isolated severe threat over
   the course of the afternoon.  A WW issuance is unlikely at this

   DISCUSSION...Scattered thunderstorms have developed in response to
   surface convergence along a trough across central Indiana southward
   into central Kentucky.  These storms are in an environment
   containing marginal lapse rates and fairly moist thermodynamic
   profiles, although breaks in the cloud cover (noted on satellite
   imagery) and resultant insolation is aiding in surface temperatures
   nearing 70F while resulting in 500-1250 J/kg MUCAPE.  Low-level
   shear is very weak in the region, although some veering of the flow
   with height may aid in storm organization and brief rotation, with
   perhaps an isolated tornado in/near any updraft that can sustain
   rotation.  This threat will be very isolated - and a WW issuance is
   not anticipated for this activity.
