A dangerous ice storm is heading toward Wisconsin, and people living in areas north of Madison should get ready for the worst.
Up to a half-inch of ice could happen through Tuesday in an area from Sauk and Columbia counties to Fond du Lac and Sheboygan counties, which could make for snapped power lines and tree branches and extremely slippery pavement conditions.
The National Weather Service issued an ice storm warning from Monday afternoon into Tuesday, so residents in the warning area are encouraged to stay inside during the freezing rain period, especially the elderly and very young.
Ice isn't the only worry in this storm.
A flood watch has been issued for parts of south-central Wisconsin and all of southeast Wisconsin, because we could see up to 2 inches of rain, especially in areas closest to the extreme southeastern corner of the state.
With frozen ground and snow still on the ground, heavy rain could cause streams to rise and flooding on roads.
"If flooding occurs, it would persist through much of the week ahead," the Weather Service said.
There's also a chance for thunderstorms in south-central and southeast Wisconsin Monday and Monday night.
If you have to drive in Wisconsin the next couple of days, check the state's winter driving map for up to the minute road conditions before heading out.
Several school districts have already closed for Monday and possibly Tuesday because of the potential ice storm, mostly north of Madison. School closings can be found online at Channel3000.com.

The heaviest rain could come during thunderstorms, which could pop up day or night.

The storm system should be out of Wisconsin by Tuesday night, with colder air moving in behind it.
