January 14-15, 2021 Blizzard Summary

Overview

A strong winter storm brought high winds and cold rain, then snow to much of the region. This combination of light to moderate snow, along with 40 to 60+ mph wind gusts, led to blizzard conditions over parts of South Dakota, Minnesota, Nebraska, and Iowa on January 14th and 15th, 2021.

This storm system caused the closure of Interstate 29 in eastern South Dakota, as well as Interstate 90 from Sioux Falls east, into south central Minnesota late Thursday evening into the early morning hours Friday. Several state highways in Minnesota were also closed for several hours. Even after they opened, portions of these highways had to be re-closed to due multiple accidents, including jack-knifed semi trucks/trailers.
