La Crosse, Wisconsin – Strong to severe thunderstorms could develop across parts of Wisconsin, Iowa, and Minnesota Friday evening as a storm system moves through the Upper Mississippi Valley.
The National Weather Service in La Crosse says scattered severe storms are possible between about 7 PM and 1 AM, with the greatest potential across northeast Iowa and southwest Wisconsin.
Cities including La Crosse, Winona, Decorah, Prairie du Chien, and Platteville could see thunderstorms as storms move from west to east across the region this evening and early overnight.
Forecasters say the primary severe weather threats include large hail, damaging wind gusts, and heavy rainfall.
While the tornado threat remains low, a brief tornado or two cannot be completely ruled out, especially in stronger storms.
Earlier Friday, widespread rain moved through the region during the morning hours. After a brief break in the afternoon, another round of storms is expected to redevelop later this evening.
Rainfall totals of around 1 inch or more are likely south of Interstate 90, with localized totals of 2 to 3 inches possible in some areas.
Because the ground remains partially frozen in some locations, heavy rainfall could lead to increased runoff into rivers and streams, as well as ponding of water in low-lying or poor drainage areas.
Drivers may encounter water on roadways during heavier rainfall, particularly during the evening and overnight hours.
Residents across the region are encouraged to stay weather aware tonight and have multiple ways to receive weather warnings if storms become severe.
If severe weather approaches, officials recommend moving indoors and seeking shelter away from windows until storms pass.
