Johnny Skeptical, pay attention to the part of the article that says " Although excessive moisture continues to plague portions of the eastern Dakotas and southern Minnesota, much of the remainder of the Corn Belt welcomed the event as a break from a dismal precipitation trend that has persisted across the eastern Corn Belt for the last two months. The saving grace has been that the corn crop was planted later than normal and a lack of substantial heat has helped curb excessive crop moisture demands." 

 There is a advantage to later planted corn LOL
