Big Corn Crop?

I am not sure when this article was written, but I think it fails to consider consider we have had weeks of the hottest summer in years.  We have a few fields with potential for big yields, but much like last year, heat is causing them to mature too fast.  Also there is no real end to the heat in sight.  Columbia, MO hit 107 Tuesday.   Several tweets today showed private forecasters revising yields down.
