End of La Nina, End of Cold and Wet
The two especially troublesome components of the winter and spring weather in the Corn Belt this year appear to be coming to an end.  Although the END is not clearly in sight for the La Nina or for the cold-wet conditions, both are moving in the direction of ending.   The measure of atmospheric pressure associated with La Nina (SOI) is now below the level qualifying as La Nina and the odds of a severe drought have begun to diminish.  Indicators for unfavorable crop weather that remain are statistical.  As of today the most likely national corn yield for 2008 is 148 BPA (up from 142 BPA).   The rain pattern that has soaked the Corn Belt shows continued migration northward and will be positioned in northern Minnesota by June 21st if the trend is maintained.     – Elwynn --
