   Mesoscale Discussion 1034
   NWS Storm Prediction Center Norman OK
   0531 PM CDT Wed Jun 14 2017

   Areas affected...Portions of central Indiana

   Concerning...Severe potential...Watch unlikely 

   Valid 142231Z - 142330Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Storms may strengthen for a brief period of time over the
   next 30 minutes or so; however, the relatively short-lived nature of
   the strengthening will likely preclude watch issuance.

   DISCUSSION...Visible satellite and regional radar data exhibit
   multiple outflow boundaries across central Indiana early this
   evening, with an expected merger of these boundaries over Boone,
   Hendricks, and Morgan counties in the near term. Rich boundary layer
   moisture and temperatures in the 80s to lower 90s have contributed
   to around 1000-1500 J/kg of MLCAPE. Surface convergence from the
   colliding boundaries may yield a local uptick in convective
   intensity (resulting in gusty winds and marginally severe hail) as
   forced updrafts utilize the aforementioned buoyancy. However, the
   small spatial/temporal scale of the threat should preclude watch
   issuance.
