Thunderstorms that started up overnight are expected to continue throughout Monday in south-central Wisconsin, with some storms possibly becoming severe.

The National Weather Service said we could see localized urban and rural flooding due to heavy rainfall, as well as large hail, damaging winds and an isolated tornado.

The best chance for severe storms is along and south of a line from Dodgeville to Madison to Waukesha.

No severe weather watches or warnings have been issued as of Monday morning, but stay tuned to forecasts as the day goes on.

Madison could see over 2 inches of rain before the storms move out, with between 1 and 2 inches Monday and between a half-inch and three-quarters of an inch Monday night.

Highs are expected to only reach 56 Monday and 60 Tuesday, then shoot up to 80 on Wednesday, said 27 Storm Track meteorologist Branden Borremans.

Rain chances could redevelop Tuesday night into Wednesday, with the best chance coming Wednesday night.
