   Mesoscale Discussion 0219
   NWS Storm Prediction Center Norman OK
   0748 PM CDT Thu Mar 14 2019

   Areas affected...Portions of southeastern Lower MI

   Concerning...Severe Thunderstorm Watch 28...

   Valid 150048Z - 150145Z

   The severe weather threat for Severe Thunderstorm Watch 28

   SUMMARY...Primarily an isolated strong to damaging wind threat
   should continue across Severe Thunderstorm Watch 28 through 02Z (10
   pm EDT).

   DISCUSSION...Recent radar imagery shows thunderstorms have congealed
   into a line across southeastern Lower MI. Modifying the 00Z DTX
   sounding for current observations across this region shows weak but
   sufficient instability to support surface-based thunderstorm
   potential for about the next hour. Effective bulk shear around 60-70
   kt will continue to organize these thunderstorms. Isolated strong to
   damaging winds should remain the main threat given the linear nature
   of the convection. With a current east-northeastward motion storm
   motion of 40-50 kt, these thunderstorms should move east of WW 28
   around 02Z, which is the scheduled expiration time.
