   Areas affected...North central Iowa...southern and eastern Minnesota   
   and northwestern Wisconsin   
      
   Concerning...Heavy snow=20   
      
   Valid 281552Z - 282145Z   
      
   SUMMARY...Heavy snow, with rates near 1 inch per hour, is expected   
   to develop by midday in east central Minnesota and northwest   
   Wisconsin.  Occasional blizzard conditions are expected into   
   southern Minnesota and northern Iowa.   
      
   DISCUSSION...Gradual erosion of a warm nose (noted in the 12z MPX   
   sounding) will continue through the afternoon from eastern MN into   
   northwest WI as a result of strengthening ascent and   
   cooling/saturation of profiles to the northwest of a deepening   
   cyclone now near the IA/MO/IL border.  Near-surface cooling from   
   northwest-to-southeast will become more favorable for   
   accumulating/heavy snow from east central MN into northwest WI   
   within the primary deformation band, while snowfall rates will be   
   lower farther southwest into southern MN/northern IA.  However, a   
   strengthening pressure gradient and rapidly falling temperatures   
   into the teens/single digits will result in blowing snow and   
   blizzard conditions (frequent gusts 35-50 mph with visibility   
   reduced to 1/4 mi or less) from southern MN/northern IA through the   
   afternoon.
