   Areas affected...northern Iowa into southern Minnesota

   Concerning...Severe potential...Watch possible 

   Valid 101939Z - 102145Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Isolated strong to severe storms are possible later this
   afternoon from northern Iowa into southern Minnesota. Hail and
   locally damaging gusts appear most likely.

   DISCUSSION...A cold front continues to push east across western MN
   and IA, with  rapidly veering surface winds and drying. Lapse rates
   remain steep due to cool temperatures aloft and daytime heating,
   with attempts at deeper convection noted across the warm sector.
   Eastern parts of MN and IA remain under the influence of outflow
   from earlier storm activity. However, at least surface air mass
   recovery will occur ahead of the cold front. 

   Given this area is in between the shortwave trough to the north and
   the departing MCS over WI and IL, the degree of new storm coverage
   in this zone is uncertain. However, at least isolated storms appear
   likely later this afternoon, with locally severe hail or strong wind
   gusts.
