A boundary was pushing through the state with ongoing convection through central Iowa through the day. As the boundary neared the area, the convection intensified and impacted central and southern Iowa in the evening to early morning hours. Two thunderstorm complexes moved through portions of central and southern Iowa with very heavy rainfall causing flash flooding. The severe thunderstorm complexes produced some hail but mainly strong damaging winds. Precipitable water values were near 2 inches in some areas with deep warm cloud depths during the event. This heavy rainfall further exacerbated conditions as some of the area had just received heavy rainfall in previous days. This led to some extended flooding for a few days and flooding on some area rivers. Several locations reported in excess of 4 inches of rain, while one location in Warren County reported over 7.50 inches of rainfall. The Emergency Manager for Marion County mentioned widespread reports of 8 to 10 inches with one report close to 12 inches of accumulated rainfall over the past few days.
