Dec 15 Snowfall Map and Summary - Dec 16 Snow Depth Map

A rapidly strengthening weather system tracked northeast from the southern Plains on Friday night, through southern Indiana Saturday evening, into New England on Sunday.  Widespread light or moderate snow on the northern side of the system overspread southern and eastern Wisconsin Saturday morning.  Favorably cold northeast winds off Lake Michigan allowed for some lake enhancement generally within 30 miles of the shore.  Snow ratios were quite high, ranging from 20:1 to nearly 40:1 in some areas.  These types of ratios yield light, powdery type snow.

Here is a summary of storm reports across southern Wisconsin.

Below is a map showing snowfall totals across the state from the system:
