An unsettled weather pattern is setting up as scattered severe storms will be possible across the Plains and Midwest on Thursday, Friday and Saturday. First, a line of storms will develop along a cold front in Iowa Thursday afternoon and then move into Wisconsin Thursday night. Damaging wind gusts and a few tornadoes will be possible with places like Waterloo, Mason City, Fort Dodge and Madison most at risk. The severe storm risk and flood threat will shift back to the west Friday and this weekend, and include parts of the Dakotas, Nebraska and Minnesota.
