The second section of winter storm is stuck between a stationary front (being followed by a high pressure system) and the cold front of the low pressure area. The wind direction is creating this circular pattern pushing the precipitation south and cycles back up to the north.

The long section of precipitation extending from Mississippi to Michigan is carrying large quantities of rain/thunderstroms. And most of the high precipiation in Minnesota/Wisconsin is where you are going to be seeing the strongest parts of the winter storm. NWS says that Eau Claire is expected to get >1" of precipitation and about 9-15" of snow after today.
