Live Updates: Severe weather, tornadoes topple trees, block roads, cause other damage in SE Wisconsin

Strong thunderstorms caused widespread damage across Wisconsin, left tens of thousands without power and triggered tornado warnings overnight.

The severe weather stretched from the Mississippi River to Lake Michigan and began Wednesday evening in northwestern Wisconsin. By 2 a.m. Thursday, the numerous tornado warnings around the state had expired.
