   SUMMARY...A multicellular cluster of storms from southeast WI across
   southern Lake Michigan will continue to pose a risk for isolated
   hail and occasionally strong downbursts for the next few hours as it
   moves into southwest Lower MI and vicinity.

   DISCUSSION...Regional radar imagery shows a cluster of multicellular
   storms extending from southeast WI across southern Lake Michigan.
   This cluster is being supported by modest warm-air advection across
   the front extending from southwest Lower MI northwestward across
   southern WI into east-central MN. A portion of this front across far
   southeast WI and northern IL have been modified by outflow from this
   cluster. 

   Much of this activity is elevated, but some of the cells along the
   southeastern periphery of the cluster are gradually approaching the
   frontal zone. Even so, the downstream air mass has yet to
   destabilize, suggesting that any severe potential over the next few
   hours will remain isolated. Thereafter, a relatively greater severe
   potential may materialize as this cluster moves into the middle OH
   Valley.

   Given the elevated storm character, hail is the most likely risk for
   the next hour or two, although a few stronger downbursts may also
   reach the surface.
