A strong winter storm developed across the Rockies and moved slowly across the Plains, bringing a prolonged period of snow and wind to western and south central South Dakota. Snow started late on the 18th and continued through the afternoon and evening hours of the 20th. A period of freezing drizzle preceeded the snow across parts of the South Dakota plains. Snowfall of 6 to 14 inches was common across the area. Amounts of 14 to 22 inches were reported across southwest and south central South Dakota, as well as the eastern slopes of the Black Hills. The Rapid City area received 15 to 20 inches of snow. Gusty winds caused considerable blowing and drifting snow across the plains, with visibilities reduced to less than a quarter mile. Interstate 90 from Rapid City to Chamberlain was closed for more than 24 hours.
