   Mesoscale Discussion 0553
   NWS Storm Prediction Center Norman OK
   0840 PM CDT Sat Apr 27 2024

   Areas affected...Northern and central Lower Michigan

   Concerning...Severe potential...Watch possible 

   Valid 280140Z - 280315Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Large hail and damaging winds possible with thunderstorms
   through the evening and early morning.

   DISCUSSION...Thunderstorms have been ongoing along a frontal
   boundary extending across the northern Lower Michigan with reports
   of hail up to penny size. This activity is likely to continue along
   the boundary, with potential for the boundary to shift southward
   through the evening/morning. Large hail and damaging winds will
   likely be the main threats, given steep lapse rates and MLCAPE
   around 1000 J/kg. A watch will be considered for portions of the
   discussion area based on convective trends.
