On This Day in Iowa Weather History

July 31

1993: During a summer of extreme rainfall and flooding the statewide average rainfall for July was 10.50 inches making this the wettest month on record in Iowa. Measurable rain fell somewhere in the state on all but two days of the month. Dubuque and Waterloo set their all-time records for June and July total rainfall, and at Cedar Rapids the total rainfall of 34.4 inches from April through July exceeded their normal amount for the entire year.

1943: A severe hail storm struck the Boone area with a resident writing that "in the city of Boone there was considerable damage to electrick signs, windows and roofs. Two greenhouses lost 2,300 panes of glass. Some automobile tops and some roofs were damaged in the southeast part of town. Crops were badly damaged or totally destroyed on about 200 farms, or on about 8,000 acres of land. Previous to the storm there were prospects of bumper yields of corn, soybeans and hemp, but after the hail some fields contained only short stumps of broken cornstalks."
