   Areas affected...Southern MN...Southwest WI...Northeast IA

   Concerning...Severe potential...Watch possible 

   Valid 302006Z - 302130Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Strong/severe thunderstorms are expected to spread from
   southern MN, southeast along the WI/IA border over the next few
   hours.

   DISCUSSION...Sustained low-level warm advection appears partly
   responsible for renewed post-MCS development across southern MN.
   Over the last hour or so updrafts have intensified along a
   reinforced boundary draped along the MN/IA border. Intense surface
   heating across northern IA has allowed surface temperatures to warm
   into the mid 90s and low-level trajectories across this air mass
   should fee the southwestern flank of upward evolving complex
   extending across southern MN into southwest WI. There is some
   concern this activity will grow upscale and propagate southeast
   along western periphery of early-day MCS cold pool. Wind/hail are
   the primary risks.
