Anyone in Sauk County only needed to look overhead Monday evening to see a wild cold front moving through the area, with myriad types of clouds moving in several directions.
The front crossed the Upper Mississippi River Valley region during the afternoon and evening hours. Southerly flow ahead of the front brought in a warm and muggy airmass, which provided fuel for severe thunderstorms that fired on the cold front. Numerous reports of severe weather were received, mostly in the form of hail, with a tornado as well.
Of the five funnel clouds confirmed in the region from north central Wisconsin to north central Iowa, only one funnel produced an actual tornado — on the Wisconsin-Minnesota border. The storms produced heavy rain and hail, but dry conditions leading up to Monday prevented any flooding.
Storms grew and changed quickly, and moved in various directions, illustrating the disorganized nature to the atmosphere Monday.
Sauk County Sheriff Chip Meister said he knew of no damage in the county.
“But near Spring Green, on the river the fire department did a canoe rescue; we were involved, too,” he said. “The people were on a sand bar, and their canoe blew away.”
The National Weather Service forecast call for mostly sunny skies for the rest of the week, with highs in the mid-70s. Thursday will bring a 30 percent to 40 percent chance of showers and thunderstorms, continuing into Friday. The weekend is forecast to be mostly sunny with highs in the low- to mid-70s.
