Major windstorms slashed across the center third of Iowa on June 29. Tree and structural damage filled the headlines, but Iowa cornfields suffered as well from a phenomenon called green snap. Green snap is the condition where rapidly growing stalks are broken by strong, sudden winds associated with thunderstorm downbursts. Over one-quarter million corn acres suffered significant green snap from the June 29 storm, based on estimates from field crop specialists.
