   Areas affected...parts of southern Wisconsin and northwestern
   Illinois

   Concerning...Severe Thunderstorm Watch 601...

   Valid 060438Z - 060515Z

   The severe weather threat for Severe Thunderstorm Watch 601
   continues.

   SUMMARY...Local severe risk may continue for another 1 to 2 hours
   across southwestern Wisconsin and far northwestern Illinois.  WW 601
   will likely be extended in time, beyond its scheduled 06/05Z
   expiration, to cover this ongoing threat.

   DISCUSSION...Latest radar loop shows a cluster of strong/severe
   storms moving east-southeastward out across southwestern Wisconsin,
   out of WW 600 and into WW 601.  Low-level moisture/instability
   diminishes with eastward extent across southern Wisconsin, where an
   easterly low-level lake fetch is indicated.  However, ample
   instability  -- particularly across Grant and Iowa Counties in
   Wisconsin and areas directly south in northwestern Illinois --
   remains, which should allow this cluster of storms to persist awhile
   longer.  With some accompanying severe risk -- mainly in the form of
   damaging wind -- to affect these counties, WW 601 will likely be
   extended in time to cover this potential.
