The episode as NWS FSD wrote it up.
Snow, primarily associated with low pressure aloft, produced heavy accumulations over extreme northeast Nebraska. The snow fell from the afternoon of January 14th into the predawn hours of January 15th. Increasing northwest winds and falling temperatures caused wind chills to approach dangerous levels near the end of the event. The winds also caused a few areas of blowing and drifting snow.
