Chicago weather: Winter storm wreaks havoc on holiday travel, over 180 flights canceled

MADISON (WKOW) — A winter storm will begin pushing through parts of southern Wisconsin by mid-morning Sunday.

Because of the narrow band of heavy snow, its possible that some locations could have no snow and within a 10-mile radius south or east could have a few inches on the ground.

This all will be caused by a low-pressure system tracking off just to our south and will push east throughout the day.

Madison (WKOW)– Accumulating snow looks to impact travel later tonight and early tomorrow morning, especially for the areas located in the warning boxes. Winter storm warnings are in effect for Green, Rock, and Walworth counties until 6 am tomorrow. Jefferson County remains under a winter weather advisory until  6 am.  We’re keeping a close eye on those specific counties as they have the best chance for seeing enough snow to cause travel issues tomorrow morning.

Snow looks to kick off this afternoon between 2 pm and 4 pm, developing from the south and east. Snow will continue to fall into the overnight hours eventually tapering off during the very early hours of Monday morning, before 6 am.

Farther south, the amounts will increase, with the snow beginning in the early morning hours. Around Cedar Rapids, 2-4″ of snow is likely to fall on Sunday. In Iowa City, we are looking at a 4-6″ snowfall. Washington will be closer to 6-10″. Wind will be strong in all areas and will lead to reduced visibility for those in the snow-covered areas. Roads as you may imagine, will become slick quickly over the south half, with very hazardous travel likely through the day.

The gradient is really tight in snowfall accumulations, so areas far south of Madison, like Beloit, and Janesville could see anywhere between 4-8″ inches. Evansville, included in the winter storm warning will be right on the cusp, on the lower end, closer to 1-4″.  Travel shouldn’t be an issue tomorrow morning for other parts of the viewing area, especially north of Madison.
