A powerful storm system that brought blizzard conditions to a wide area of southern and central Minnesota, as well as adjacent west central Wisconsin, developed early Saturday morning in the southern Rockies. The storm moved out into the Plains of Kansas Saturday morning, February 23th, and tracked northeast to northern Missouri by the afternoon. The storm kept steady during this time frame, but intensified rapidly during the evening and overnight period of Saturday and Sunday, February 23rd and 24th. The storm dropped 20 millibars from Saturday evening, through Sunday morning as it moved from northern Missouri, to the northern Great Lakes.
Snow began in southern Minnesota Saturday afternoon February 23th, and ended Sunday morning. The heaviest snowfall occurred from south of Blue Earth (Faribault County), to Faribault, and Hastings in Minnesota, and to River Falls, and Rice Lake in west central Wisconsin. These areas received between 6 and 12 inches of snow, with localized areas of 12+ inches.
Roads began to close in south central Minnesota before 10 PM CST, Saturday, February 23rd. As winds increased during the night, and Sunday morning, several other roads, including I-35 & I-90 closed due to impassable conditions. The road closures extended northward across portions of southwest, west central and southeast Minnesota as winds increased and snow drifted over the road Sunday. Several social media pictures indicated that snow drifts were as high as 20 feet in some locations in southern Minnesota. Even military vehicles that are made for deep snow, became stuck.
Wind speeds started to increase late Saturday night, and peaked Sunday, and slowly subsided Sunday afternoon and evening as the storm system moved out of the region. However, some roads in south central Minnesota remained closed through Monday as snow plows reported drifts in excess of 20 feet.
During the height of the storm, the Minnesota Homeland Security and Emergency Management tallied approximately 600 stranded travelers who were rescued off of snow-filled ditches, drifted shut roads, and snowbanks.
Troopers and the Minnesota Department of Transportation officials worked near 24 hours straight to get stranded motorists out of the Straight River rest stop along I-35 south of Owatonna. In Blue Earth County, 150 vehicles were reported off the roads, some were rescued. Seven vehicles were reported off the road in Red Wing. In Freeborn County, crews worked to rescue nine people from two trains stuck on tracks. As individuals were rescued, numerous shelters were opened across southern Minnesota.
The following was the breakdown of the rescues across southern Minnesota;
Brown County: 5.|Chippewa County: 21.|Cottonwood County: 8.|Freeborn County: 91 (including from stranded trains).|Le Sueur County: 46.|Renville County: 33.|Rice County: 30. |Steele County: 200-plus. |Stevens County: 12. |Swift County: 20.|Watonwan County: 10.
