What happened

The episode as NWS MKX wrote it up.

A new blanket of snow (3 to 6 inches) was deposited across south-central and southeast Wisconsin on January 21st. Specific snow accumulations inlcude 6 inches near Beaver Dam (Dodge Co.), 5.8 inches in Germantown (Washington Co.), 5.2 inches just west of Lake Mills (Jefferson Co.), 5.9 inches at Madison's Truax Field (Dane Co.), and 3.3 inches at Milwaukee's Mitchell Field (Milwaukee Co.). The axis of the greatest amount of snow accumulations (5 to 6 inches) stretched from (southern Sauk County to central Dodge County to southern Ozaukee County. Near the Illinois border accumulations were around 3 inches. Numerous vehicle accidents were reported by the media. Several of the accidents in Dane County became multiple-vehicle. Sypotically, a surface low pressure moved through northern Illinois into southern Lower Michigan, which allowed for warm air advection on the front side of the system to generate snow.
