Having farmed for over 35 years and having experienced the wettest year in history on our farm in 2010 I suggest you take a big look at the current weather forecast. The weather patterns are not anywhere near normal and no change in sight. Too wet is worse than too dry in that you cannot get a quick fix with rain. After many years of mostly worrying about dryness I have a new perspective now. Perfect summer weather won't matter much if the crop is seeded too late. This is an excellent website for looking at longer term weather and verifies what Freese-Notis Weather is saying:

"Basically the entire Corn Belt is going to see another two inches of precipitation over the next ten days, but that does not accurately tell the story for especially the southeastern half of the region as rains there in that period will be in excess of four inches and some places in that time frame may see upwards of eight inches"
