Strong low pressure moved from the central Plains early morning on March 31 into the western Great Lakes by early morning April 1. The area was just on the south side of the more significant banded precipitation, and featured enough instability for a little thunder to mix in during the morning hours.  Most precipitation started as rain or freezing rain, mixing with and changing to snow through the afternoon and early evening from west to east. Winds behind the system increased to a gusty 30 to 40 mph at the peak, with snowfall generally from 2 to 4 inches north of I-90 and west of the James River, as well as southwest Minnesota mainly north of Highway 14.  The combination of wind and snowfall led to some near-blizzard conditions for a brief time during the late evening and early overnight hours of April 1.
