To check out the latest snow cover across southern Wisconsin and the entire region, use the National Operational Hydrologic Remote Sensing Center (NOHRSC) Interactive Snow Information web site. Here is the snow cover depiction from early Thursday morning around 5 am:
A trace to 2 inches remained over southeast Wisconsin including the Milwaukee, Fort Atkinson and Janesville areas, with widespread bare spots across Racine and Kenosha counties and portions of Walworth County. The snow cover increased substantially to the north and west toward Madison, Sheboygan, Baraboo, Green Lake and Portage areas but the snow cover has been reduced to between 4 and 10 inches, though a few locations were still reporting 12 inches or more.
The latest listing of snow cover from across Wisconsin is available here.
Other very useful information is available from the NOHRSC snow information site including hourly snow melt and the water equivalent of the current snow cover.
Here are some high resolution MODIS satellite images from Friday, January 4th, Monday, January 7th, and Wednesday, January 9th. The warmer temperatures of the past several days has led to the decreasing snow cover across portions of the Upper Midwest, including far southeast Wisconsin.
Mild temperatures for the rest of this week into the weekend, and widespread rain beginning later this afternoon through Friday morning, will continue to shrink the snow cover across portions of the Upper Midwest.
