A cold front was sinking slowly southeast across Iowa. Ahead of the front was warm and unstable air with dew point temperatures in the middle to upper 60s. Thunderstorms erupted during the mid part of the day and continued through most of the afternoon. Many of them produced heavy rainfall, small hail, and winds of 40 to 50 MPH. One storm did become severe in Cedar County. Golf ball-size hail and winds of 70 MPH occurred south of Clarence. It did to damage to a farmstead there. Another storm produced high winds in Winneshiek County. The winds flattened a 60 X 65 barn on a farmstead southeast of Cresco. Spotty damage was reported elsewhere, but was not due to winds of severe strength. For example, two barn doors were ripped off by 40 to 50 MPH winds in Clinton County near Grand Mound.
