A majority of Iowa's summer time rainfall comes during the overnight hours. During the drought of 2012, this contribution was largely missing. So far, 2013 has been a different story with multiple heavy rainfall events happening during the overnight hours. The featured chart presents the hourly precipitation totals for Des Moines and the long term climatology for May. The 3-8 AM totals have far exceeded climatology. The totals shown were up until 12 AM this morning and another half inch was fallen today.
