Severe thunderstorms tore across parts of the Midwest on Tuesday afternoon and evening, producing multiple tornadoes and unleashing destructive hail and damaging wind.

In Independence, Iowa, the roof of a warehouse was blown off, damage that Storm Chaser Aaron Rigsby said may have been caused by a tornado or intense straight-line winds. Similar storm damage was also reported in Union Center, Wis. Local and National Weather Service teams are expected to conduct surveys this week to confirm where tornadoes touched down and assign ratings.

In all, six tornadoes were reported across eastern Iowa and southern Wisconsin. But the broader, more widespread threat came from powerful wind gusts and large hail.
