Meteorologist Gail Martell of MartellCropProjections.com says the U.S. corn crop is off to a shaky start due excessive rainfall across Iowa, Minnesota, Wisconsin and North Dakota. On top of heavy rainfall, she notes that below-normal temps on average for the region have also contributed to a crop that is behind the average pace of development.
"Iowa rainfall this season to date is 178% of normal, while the national April-May rainfall is 141% of average. Weather records are always a red flag for crop damage. Last year it was historic drought, this year, excessive wetness threatening to produce severe damage in corn," notes Martell. "The weather forecast continues wet in the Midwest as recurring thunderstorms develop along a stalled frontal boundary the next few days."
