A significant flash flood event developed later on the 12th as heavy rains and severe storms developed along a stationary boundary located over central Iowa in the mid-morning hours. Storms continually redeveloped in a narrow band along the front throughout the day, before finally lifting north to produce more heavy rains over the upper Des Moines River basin. WSR-88D radar precipitation estimates were biased upward by the copious hail production in these storms. Radar estimates of 6 to 8 inches
