A couple rounds of severe weather struck the region on Saturday, July 23, 2022.

The first moved across the local area in the afternoon as storms developed over southern and central Minnesota. Initially storms mostly produced large hail and locally damaging winds. As the storms pushed into southeast MN and northeast IA, they started to coalesce into clusters, eventually evolving into larger bowing segments producing 70 mph winds, broader swaths of wind damage, and at least 3 small tornadoes. Hardest hit was stretch generally just south of I-90, across Houston Co, MN through Vernon Co, WI. These storms exited into central/eastern Wisconsin by 5 pm, allowing for a brief break before the next round of storms developed and moved in.

Storms redeveloped by early evening, becoming strong to severe as the evening wore on. Mostly heavy rain and wind gusts to 40 mph were observed, but another swath of damaging winds and at least 1 tornado developed across parts of northeast IA - focused in Winneshiek and Allamakee counties. These storms would push east overnight. Most extensive damage was to areas around Calmar and Waukon, IA.
