   Mesoscale Discussion 1049
   NWS Storm Prediction Center Norman OK
   0939 PM CDT Thu Jul 12 2018

   Areas affected...southern MN into central WI

   Concerning...Severe Thunderstorm Watch 274...275...

   Valid 130239Z - 130415Z

   The severe weather threat for Severe Thunderstorm Watch 274, 275
   continues.

   SUMMARY...A few strong wind gusts may be possible for another hour
   or two as gradual weakening trend ensues this evening. Additional
   downstream watches are not expected.

   DISCUSSION...Portions of the line of storms tracking east/southeast
   across western into central WI have weakened this evening. Embedded
   cells occasionally have increased in intensity, but overall trends
   suggest storms are struggling to maintain intensity as boundary
   layer stabilization continues due to loss of heating and as storms
   shift away from stronger deep layer shear. While some strong gusts
   may persist another hour or two, downstream watches are not expected
   and existing watch may be canceled prior to expiration.
