This past Tuesday evneing saw an impressive duration and accumulation of rainfall with totals by Wednesday morning approaching 4 inches. The featured graph is a 1 minute timeseries from the KCCI-TV SchoolNet site at St Cecilia in Ames showing rainfall accumulation and hourly intensity based on 20 minute intervals. The plot shows that outside of the 1.25 inch/hr intensity around 5 PM, most of the event saw intensities of around 0.5 inch/hr or less. The long duration gave the soil a chance to soak in some of the water and limited the flooding impacts to urban areas.
