   Mesoscale Discussion 1252
   NWS Storm Prediction Center Norman OK
   0235 AM CDT Fri Jul 07 2017

   Areas affected...Portions of southwest into south-central Lower

   Concerning...Severe potential...Watch unlikely 

   Valid 070735Z - 070930Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Locally strong/damaging wind gusts will remain possible
   into the early morning across portions of southwest into
   south-central Lower Michigan.  WW issuance is unlikely.

   DISCUSSION...At 0710Z, mosaic radar imagery showed a band of storms
   extending from Kent to Allegan counties, moving to the
   east-southeast around 50 kt.  This band of storms should continue to
   move to the east-southeast along a moderate instability gradient. 
   At 720Z, GRR WSR-88D velocity data indicated wind speeds of 50-60 kt
   at 350-400 fl above-radar-level spreading across southwest Kent
   County. Despite some surface-based inhibition that would limit
   stronger wind gusts from reaching the surface, reported severe wind
   gusts with this band of storms and aforementioned kinematics suggest
   locally strong/damaging wind gusts remain possible into
   south-central Lower Michigan.  Convection/storms developing east of
   the aforementioned fast-moving band of storms should convectively
   overturn the downstream air mass and eventually result in a
   deceleration of the band of storms.
