   Mesoscale Discussion 0960
   NWS Storm Prediction Center Norman OK
   1002 AM CDT Sun May 29 2022

   Areas affected...Portions of far southeastern MN into western WI and
   far northeastern IA

   Concerning...Severe Thunderstorm Watch 286...

   Valid 291502Z - 291630Z

   The severe weather threat for Severe Thunderstorm Watch 286

   SUMMARY...An isolated severe hail threat appears to be diminishing.
   Downstream watch issuance is not expected.

   DISCUSSION...Elevated thunderstorms driven largely by low-level warm
   advection have struggled to intensity over the past couple of hours
   across southern MN. This activity is approaching the eastern bounds
   of meaningful MUCAPE based on latest mesoanalysis. Deep-layer shear
   is also marginal, around 25-30 kt. Current expectations are for the
   already marginal hail threat associated with these thunderstorms to
   continue diminishing as they move eastward across western WI over
   the next couple of hours. The remaining valid counties in Severe
   Thunderstorm Watch 286 should be able to be cleared shortly, and
   downstream watch issuance is not expected.
