What happened
The episode as NWS MKX wrote it up.
Snow fell across south-central and southeast Wisconsin on January 9th during a 9-hour period, with the greatest accumulations south of a Madison to Milwaukee line. A narrow band of 6 to 8 inch accumulations occurred from southern Iowa County through southern Dane County to the Burlington (Racine Co.) and Paddock Lake area (Kenosha Co.). Societal impact was minimal, therefore, this event was documented as a winter weather event rather than a Winter Storm event. Snowfall amounts north of a Madison to Milwaukee line ranged from 2 to 4 inches. Both Oregon (Dane Co.) and Burlington (Racine Co.) gathered 8.5 inches, while 8 inches fell in La Grange (Walworth Co.). Palmyra (Jefferson Co.) came in with 6 inches and 5.7 inches accumulated in Janesville (Rock Co.). The Madison (Dane Co.) airport measured 3.6 inches and the Milwaukee Airport came in with 3 inches. The media reported that dozens of vehicle accidents occurred. Synpotically, low pressure moved east along the Iowa-Missouri border through Central Illinois and then up the Ohio River Valley.
