   Areas affected...portions of central into eastern Wisconsin and
   western Upper Michigan

   Concerning...Severe Thunderstorm Watch 653...

   Valid 270411Z - 270515Z

   The severe weather threat for Severe Thunderstorm Watch 653
   continues.

   SUMMARY...The severe threat continues in and near Severe
   Thunderstorm Watch 653. Damaging wind gusts are the main threat, and
   this threat should persist for at least a few more hours.

   DISCUSSION...A mature MCS with a history of strong, damaging gusts
   continues to progress eastward over central WI. Given nocturnal
   cooling, temperatures are dropping into the 75-80F range, suggesting
   that MLCINH should be on the increase ahead of the MCS. While this
   may dampen wind damage potential to some degree, at least some
   threat for damaging gusts should continue for at least a few more
   hours given 3000-4000 J/kg MLCAPE preceding the line.
