Overview

After a couple days of spotty heavy rain from thunderstorms, the area was hit harder on Saturday, June 9th from a large, dangerous storm that moved into northern Iowa, followed by lines and waves of strong to severe thunderstorms.

Some of the initial storms produced large hail and damaging wind. These had a tornado threat with them. Then storms transitioned more into strong wind producers and dropped very heavy rain over parts of the region.

The hardest hit areas were from far southern Minnesota, across northeast Iowa, into southwest Wisconsin. Rainfall totals exceeded 6 inches in some communities and many rivers rose to flood levels.
