Weather goes from wet to dry and back with some regularity. We go through the changes and call them weather cycles. Weather, however, is not as cyclical as many of us would like to believe. What is average for a few decades must be adjusted for another period of time.

For example, the 20 years from 1993 through 2012 were very wet — the wettest years in the 139-year record for Fargo-Moorhead. Average rainfall went up 20 per cent over the long term average.

Since then, rainfall has tapered off some and much drier weather will likely return at some point in the future, but no one knows when. The drought of the 1930s lasted for about 12 years, devastating the economy of the Great Plains. We are better prepared now than we were then, but a long-term drought would greatly impact our way of life. And it will happen someday. Expect the unexpected.
