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

Concerning...Heavy snow=20

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.
