Overview

On January 23rd, 2017 a winter storm moved into the northern plains. Initially this system brought freezing fog and patchy freezing drizzle to the area, creating a layer of light icing. Snow began moving in early on the 24th, and lasted into the next day. Nebraska, southern South Dakota, and the northern Black Hills received the most snow. In our area, the highest snowfall amounts reported were 14 inches in south central South Dakota. Breezy northwest winds created some areas of blowing snow, but generally winds were not very strong with this storm system.
