   Areas affected...Northeast South Dakota into parts of southwest
   Minnesota

   Concerning...Heavy snow 

   Valid 281135Z - 281400Z

   SUMMARY...A band of moderate to heavy snow is moving slowly eastward
   across northeast South Dakota and into southwest Minnesota.

   DISCUSSION...A narrow band of around 1 inch+ per hour snowfall rates
   is moving slowly eastward across northeast South Dakota and into
   southwest Minnesota. Observations are somewhat limited within this
   narrow band, but where the heaviest snow has been observed, less
   than 1/4 mile visibility was observed in Redfield, SD. This band is
   associated with strong frontogenesis centered between 850 and 700mb.
   This band will drift slowly eastward through the morning and will be
   mostly across southern Minnesota by mid-day. Frontogenesis strength
   should maintain through the afternoon. However, drier air across
   Minnesota may lessen rates somewhat as this band shifts east.
