A powerful cold front will bring strong winds, sharply colder temperatures, and dangerous wind chills to the state later in the day on Wednesday and going through Wednesday night and Thursday.
The arctic cold front will move into the region from Canada during the day on Wednesday. Behind the front, strong northern winds will create areas of blowing snow, reduce visibilities as low as a quarter of a mile, and bitterly cold wind chill readings down to 20 below zero.
Besides the winds and colder temperatures, there is a chance of light snow to move into South Dakota. Snow amount will generally be under one inch with some isolated higher amounts in the extreme northeast, South Dakota. The northern Black Hills may see higher amounts with one to four inches are expected.
