Overview

A powerful storm system impacted central and northeastern South Dakota and western Minnesota from the morning through evening of December 4th, 2017. For many, this was the first accumulating snow event of the season. Strong winds resulted in blizzard conditions across the area as well. Cold, single digit and lower air moved in behind this system as well.
