   Areas affected...parts of northern Wisconsin and into Upper Michigan

   Concerning...Severe Thunderstorm Watch 552...

   Valid 051649Z - 051845Z

   The severe weather threat for Severe Thunderstorm Watch 552
   continues.

   SUMMARY...Storms -- and local severe risk -- persist across
   remaining portions of WW 552.

   DISCUSSION...Latest radar loop shows some weakening/decreased
   organization with the band of storms moving across eastern portions
   of WW 552 -- i.e. across northwestern Wisconsin -- at this time. 
   However, the downstream airmass -- both east and south of the
   convection -- continues to destabilize as diurnal heating pushes
   temperatures into 80s.  Though short-term trends, with respect to
   severe potential into Upper Michigan and a greater portion of
   northern Wisconsin, suggest lessened risk over the next hour or so,
   we will continue to monitor this convection for signs that continued
   downstream destabilization begins to aid in a re-intensification of
   storms, which could require new WW issuance.
