   Mesoscale Discussion 1351
   NWS Storm Prediction Center Norman OK
   0238 PM CDT Wed Jul 19 2017

   Areas affected...Portions of southeast MN...southwest WI...northeast

   Concerning...Severe potential...Severe Thunderstorm Watch likely 

   Valid 191938Z - 192145Z

   Probability of Watch Issuance...95 percent

   SUMMARY...A compact convective system is spreading
   eastward/east-southeastward across MN with accompanying severe
   wind/hail potential. The issuance of a Severe Thunderstorm Watch
   downstream of Watch 420 is forthcoming.

   DISCUSSION...A compact, bowing MCS across southern MN is moving
   eastward to east-southeastward around 50 kt. This activity has
   recently attained more of a southward component to its motion, as
   the air mass continues to strongly destabilize near and south of a
   warm-frontal zone along which this system is tracking. This activity
   has a history of producing severe wind gusts, and will pose severe
   wind/hail potential as it spreads downstream of Severe Thunderstorm
   Watch 420. Additional details regarding the evolution of this system
   are contained in Mesoscale Discussion 1348, and will be contained
   within a forthcoming MCD.
