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.
