An area of strong low pressure just east of Sheboygan will shift into lower Michigan this evening. This system brought a round of light to moderate snow to southern Wisconsin Tuesday morning. The second, more expansive area of snow will be affecting southern Wisconsin into the evening, tapering off from west to east through the late evening and overnight. Total snow accumulations of anywhere from around 1 inch near the Illinois border to 3 to 6 inches from Westfield to Berlin, West Bend, Hartford, Fond du Lac and Sheboygan is expected.

Here is a graphic of the preliminary local storm reports:
Strong northwest winds on the back side of the low will cause considerable blowing and drifting snow this evening. The winds will taper off gradually during the overnight. Given the fluffy and powdery nature of the snow, visibilities will be reduced at times with the blowing snow. The falling and blowing snow will continue to affect the evening commute.
A Winter Storm Warning remains in effect for most of central Wisconsin, and north of Milwaukee and Madison.
A Winter Weather Advisory remains in effect elsewhere across south central and southeast Wisconsin.
