Death comes to us all. Life's but a walking shadow | If you plot the precipitation anomaly (difference around the ave.) of the March to August precipitation anomaly vs the previous Oct- Jan. precipitation anomaly for the Corn Belt, there just doesn't seem to be any correlation. As you can see below. Our idea that the dry fall during 2011 presages the 2012 drought might very well just have been a coincidence. Below is a scatter plot going back to 1896.
I'm not even sure that the excess precipitation in the Pacific Northwest is an indication of anything next summer. A sustained dry period next summer is more likely the unfortunate alignment and coincidence of multiple global weather patterns just the right time for a long enough period of time.
