A cold front moved southeast out of the Dakotas into Iowa during the late afternoon and evening hours. Parameters for severe weather were weak. The instability was there, but moisture, inflow, and shear were marginal. A mesoscale convective system developed over Minnesota during the afternoon hours. As the evening progressed, the storms developed toward the southwest. Eventually the complex overspread about the northeast two thirds of Iowa. Some severe weather was reported with the storms, but it was limited. Dime-size hail fell in the northwest counties of the state. In O'Brien County, golf ball-size hail fell at Sheldon. Some roof damage was reported there. Hail damage to property was minor, however many crops were damaged. Gusty winds were common with the storms, but there were few wind gusts reaching severe criteria. Minor damage was reported in Spencer as winds clocked at 60 mph blew through the city.

What these are

Thunderstorm Wind
Winds from a thunderstorm of 50 knots (58 mph) or more, or lower winds that caused damage or casualties. Measured gusts are marked MG, estimated EG.

After NWS Directive 10-1605, the rules offices file Storm Data by.
