Winds gusting above 50 mph combined with existing snow cover and 1 to 4 inches of new snow to produce prolonged blizzard conditions. Visibilities near zero and drifting snow made travel impossible. Even snow plows were pulled off the roads until conditions improved. Interstate highways 90 and 29 were closed for more than 12 hours. Many businesses, colleges, and technical schools closed during the storm. Wind chills dropped to colder than 60 below zero at times. The only reported damage was minor, such as a few signs blown over, but the economic impact of the storm was still large in lost travel, business, and snow removal costs. The main shopping mall in Sioux Falls was forced to close early on the second busiest shopping weekend before Christmas.
