There was a major contrast in precipitation across Iowa during May. Preliminary monthly totals vary from only 1.07 inches at Dubuque to 12.53 inches at Red Oak. At Dubuque this was the 6th driest May among 153 years of records while at Red Oak it was the 3rd wettest May among 93 years of data. The bulk of the month���s precipitation came during two periods. The first, on May 5-7, brought flooding rains to much of west central and southwest Iowa with 6.95 inches at Randolph and 6.77 inches at Logan. However, this early month rain largely missed eastern Iowa where Davenport and Dubuque received only 0.02 inches.  The heavy rains early in the month resulted in widespread moderate flooding over the south and west part of the Des Moines CWA.  Some damage occurred with the flooding, which lasted for several days, but much of the damage was not severe.  Elevated streamflow continued in May, with some periods of flooding at the beginning and end of the month.  Flooding was mainly confined to the Raccoon, Des Moines, Nishnabotna, and Grand Basins, with elevated levels along the Des Moines continuing through the month.
