2000: Two rounds of severe weather struck portions of southwestern, central, and east central Iowa. The first group of storms struck central Iowa during the mid-morning hours, producing very large hail with stones nearly the size of softballs falling in Ames resulting in extensive damage to vehicles and roofs as well as crop damage in surrounding areas. The second round of storms developed by mid-afternoon and moved eastward into the evening, producing prolific amounts of hail including stones the size of baseballs that caused considerable crop damage and broke windows around Atlantic. These storms also produced a couple of short-lived tornadoes in Boone and Guthrie counties as well as locally very heavy rainfall with flash flooding occurring across portions of Cass, Adair, and Tama counties. In Tama County 1.5 inches of rain fell in just 15 minutes with a total of about 4 inches of rain in two hours, flooding the streets with water around 3 feet deep. Further west in Cass and Adair counties 3 to 5 inches of rain fell in about two hours, closing Interstate 80 in northern Adair County with 2 to 3 feet of water covering the road.
1894: Extremely hot temperatures and exceptionally strong southwest winds resulted in significant damage to the corn crop that was later exacerbated by a very dry period following into August. On July 26th every station in Iowa reached at least 100 degrees and the statewide average high temperature was a searing 104.1 F. The prospect for corn was reduced from a condition of 107 percent of normal on July 1 to an actual yield of only 12 bushels per acre by the harvest.
