A large and long duration snow event developed across the Rockies on April 8th, and spread north-northeast across the Plains, and into the Upper Midwest for three days. The first bands of snow, sleet and rain developed across southwest Minnesota the early morning of Tuesday, April 9th, and spread a large area of mainly sleet and rain across southwest, and into southern Minnesota.  Some areas of southwest Minnesota received over 3 inches of snow southwest of Redwood Falls. Elsewhere, amounts were around a trace, up to an inch across the southwest, and west central parts of Minnesota. This area of precipitation moved eastward across southern Minnesota and ended by the afternoon.
A second wave of snow, sleet and rain, including some thunderstorms, moved across southern Minnesota during the evening of Tuesday, April 9th. On the northern edge of the precipitation bands, a few inches of snow fell across the southern portion of the Twin Cities Metro area, and eastward into west central Wisconsin. This area moved quickly eastward across the western Great Lakes by early Wednesday morning, April 10th.
The main winter storm event occurred late Wednesday evening, and continued through Thursday morning.  Most of the heavy snowfall ended before noon Thursday, with lingering light snow and flurries during the afternoon. During the morning of Thursday, thunder snow developed along the leading edge of an intense jet streak which enhanced the the lift and created snow bands of 1-3 inches per hour.  Some areas of east central and central Minnesota received between 6 to 8 inches of snow in less than 4 hours.  There were also areas of heavy sleet and freezing rain that occurred briefly Thursday morning across far east central Minnesota and west central Wisconsin, which kept snowfall amounts lower.
The Minneapolis light rail was halted for several hours due to significant ice that accumulated on the rail lines. This had not happened in the 8 years that the rail service had been running.
