Several rounds of showers and thunderstorms developed across all of eastern Iowa, northwest Illinois and far northeast Missouri on the afternoon of Thursday May 26, 2022. These showers and storms formed in response to an area of low pressure moving across eastern Missouri into central Illinois during the afternoon and evening. This activity slowly rotated around the low, allowing showers/storms to produce torrential rainfall over areas they impacted.

During the evening, repeated rounds of showers and storms impacted the city of Danville, IA, and lead to flash flooding across the city. Per emergency management, water flowed into homes, apartments and school and washed out several gavel roads on the west side of town. There was an unofficial measured rainfall amount of 9 inches in the city.
