   Areas affected...2Southern Wisconsin into central Lower Michigan

   Concerning...Severe Thunderstorm Watch 106...107...

   Valid 140443Z - 140615Z

   The severe weather threat for Severe Thunderstorm Watch 106, 107
   continues.

   SUMMARY...Occasional damaging gusts of 60-70 mph and isolated large
   hail near 1 inch in diameter will be possible along the conglomerate
   outflow through 06z.

   DISCUSSION...Thunderstorms have grown upscale into an extensive QLCS
   with a conglomerate cold pool extending from northeast IA across
   southern WI and into central Lower MI.  The predominately east-west
   orientation of the QLCS in westerly flow aloft suggests that most of
   the stronger updrafts will remain slightly to the cool side of the
   southeast-moving outflow.  A few smaller scale bowing segments will
   be possible, especially with cell mergers into the line, which is
   more probable across central Lower MI.  Occasional damaging outflow
   gusts of 60-70 mph and hail near 1 inch in diameter will be the main
   threats through at least 06z.
