Heavy rain causes flooding, street closures
More than 2 inches of rain fell in Madison overnight
More storms and flooding are possible Tuesday after heavy rain dropped more than 2 inches of rain on the Madison area overnight.
The unsettled weather will continue through the middle of the week for southern Wisconsin, according to News 3 meteorologist Haddie McLean. A flash flood watch for much of southern Wisconsin has been extended until 7 a.m. Wednesday.
"Once the latest rain comes through this morning, Dane County should get a break," said McLean. "But tonight, we could have more storms, which could also bring damaging winds along with the heavy rain."
McLean thinks another 1-2 inches of rain could fall over southern Wisconsin, with local amounts of up to 4 inches possible.
The heavy rain has caused some road closures in Dane County, and much of southwest Wisconsin.
In Madison, Park Street was closed for a time early this morning between Spring and Dayton due to high water. It has reopened. There are also some problems at U.S. Highway 14 near Old Stage Road. The road is passable, but cars need to slow down.
West of Madison, road conditions are much worse.
In Richland County, Wis. Highway 60 is closed in both directions from Muscoda to Gotham because of flooding. The detour is north on Wis. highway 80 to U.S. 14 and then back to 60.
Highway 133 from Blue River to Boscobel is closed in Grant County.
And in Crawford County, Wis. Highway 35 from U.S. highway 18 in Prairie du Chien to Highway E in Lynxville is closed, as well as Wis. Highway 179 from Wis. Highway 27 in Eastman to Highway 131 in Steuben. U.S. 61 is also closed north of Boscobel due to a mudslide.
A warm front will lift northward and become nearly stationary across Iowa, southern Wisconsin and northern Illinois.
Any thunderstorms that develop will be efficient rainmakers, according to McLean. Rainfall potential is high for the next few days, with another 1-3 inches expected and locally higher amounts of rain possible.
The rain will exacerbate the flooding problems already occurring in portions of southwest Wisconsin, according to McLean. A flash flood watch is in effect for southwest and south-central Wisconsin until 10 a.m. Tuesday.
The rains caused flooding and mudslides over the weekend and into Monday.
In addition to the threat of heavy rain, there is also a slight risk for severe storms with large hail and damaging winds.
The weather pattern should quiet down by the end of the week. Humidity levels and temperatures will drop. High temperatures will be in the upper 70s throughout the weekend.
