   Areas affected...southern Minnesota...northern Iowa...and much of
   Wisconsin

   Concerning...Severe Thunderstorm Watch 239...

   Valid 022232Z - 030030Z

   The severe weather threat for Severe Thunderstorm Watch 239
   continues.

   SUMMARY...Damaging hail and wind is expected to spread
   east/southeast from southern Minnesota across northern Iowa, and
   into much of Wisconsin where an additional watch may be needed.

   DISCUSSION...Cells have become severe over southern MN near the wind
   shift, and approaching the surface pressure trough where
   temperatures are hot. The deeply mixed boundary-layer, substantial
   instability, and influence of the approaching shortwave trough
   support increasing storm trends this evening as they continue
   east/southeast into northern IA and western WI.

   Other storms north of the wind shift over northwest WI may
   eventually become better rooted in the boundary-layer as outflow
   deepens and supports propagation. Eventually, these storm systems
   may merge outflow boundaries. Central and southern WI is strongly
   unstable, and should support a continued severe threat as storms
   approach this evening. As such, an additional watch may be needed.
