Roads may freeze overnight after rainy day

A winter storm system is moving through southern Wisconsin. Rain and even a few thunderstorms this evening will mix and change to snow overnight.

As temperatures fall below freezing, wet roads and standing water may begin to freeze, leading to slick travel conditions overnight into Tuesday morning.

Snow accumulations in southern Wisconsin will generally be light, with potential of up to around 2 inches in a few spots, although most areas will see less than that. There may be the potential for a little more snow over southeastern Wisconsin, especially near Lake Michigan if a heavier band of lake effect snow forms along the shoreline.

As a result, a Winter Weather Advisory has been issued overnight into Tuesday morning for southeastern Wisconsin, including the Milwaukee metropolitan area, as well as Rock and Walworth counties.

In central and northern Wisconsin, moderate to heavy snowfall will continue this evening. Total snowfall amounts of 8 to 15 inches are possible from Iowa through southeastern Minnesota and into northwestern Wisconsin, although localized amounts up to 18 inches are possible over southwestern Minnesota.

Strong winds of up to 45 mph are causing whiteout conditions over western Iowa and southwestern Minnesota, and travel is not recommended in those areas overnight. Fortunately for southern Wisconsin, this part of the storm will stay north and west of a La Crosse to Wausau line.
