What happened
The episode as NWS LSX wrote it up.
Heavy rainfall in the north hastened the snowmelt in Minnesota and Iowa. Although the flood wave attenuated significantly by the time it reached the St. Louis Hydrologic Service Area (HSA), the flooding was still significant. Quincy, IL reached the 10th highest crest of all time reaching 23.5 feet (flood stage 17) on April 27. The flooding was mainly limited to natural floodplain and agricultural lowland, although a few businesses along the riverfront were affected.
