Overview
|
A significant winter storm impacted much of the region from February 21st through the morning of February 23rd, 2023. Waves of moderate to heavy snow produced over a foot of snow in many locations, especially near and north of Interstate 90, while wind gusts up to 40-45 mph produced blizzard conditions and significant drifting. Interstate highways west, north and east of Sioux Falls were all closed at some point during the storm, as were some state highways in southwest Minnesota. |
