   Mesoscale Discussion 1059
   NWS Storm Prediction Center Norman OK
   0353 PM CDT Fri Jun 16 2017

   Areas affected...Northern lower MI

   Concerning...Severe potential...Watch unlikely 

   Valid 162053Z - 162230Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Scattered strong thunderstorms will continue this
   afternoon, with some threat for isolated hail and/or locally
   damaging wind.

   DISCUSSION...Thunderstorms have recently increased in coverage and
   intensity across northern lower MI. Storms near Alpena have
   exhibited weak rotation, and some threat for hail and localized
   damaging wind will exist with this activity as it approaches Lake
   Huron over the next 1-2 hours. Additional development is underway
   further to the southwest, and with MLCAPE of 500-1000 J/kg and
   effective shear of around 30 kts, some weak organization is possible
   with a corresponding threat of localized hail and damaging wind with
   any additional development. The threat is expected to be too limited
   in spatiotemporal extent for watch issuance.
