Yeah maybe so. Not sure how they calculate "normal". I would think there would be more weight assigned to recent years as opposed to 100 years ago.Over the last 14 years or so "normal" has been more like the maximum. Here is a graph I put together averaging rainfall totals from airport data across the state since 2010. Rainfall total on right and percent of normal (32 inches) on left. If you assume normal distribution the odds of only having 2 years in that stretch where we barely reach the mean is pretty darn low. May be time to consider a new "normal" for Iowa.
