If the bitter cold doesn't feel wintry enough for you, clouds are increasing in southern Wisconsin ahead of a fast moving storm. An Alberta clipper passes to our south overnight with light snow forecast from this evening through the pre-dawn hours Tuesday. This snow will be light and fluffy. It is forecast to start between 6pm and 9pm Monday evening and end between 2am and 5am Tuesday. Accumulations look light for our area of the state. The forecast calls for a dusting of snow in Fond du Lac and Sheboygan. For Milwaukee and Waukesha, expect one to three inches of snow. In Walworth and Kenosha counties three to four inches of snow is possible. In Lafayette, Green and Grant counties, snowfall could reach six inches.
The heaviest path of snow with this system is forecast to track from Iowa south and east into central Illinois. That is illustrated with this graphic:
The snow is long gone by 7am Tuesday with our very cold temperatures in place through the weekend. Expect overnight lows below zero almost every night through Saturday. As far as more snow, as of today it only looks like more flurries and snow showers Thursday and Saturday. So, nothing big.
