Since I have been in Iowa,,has been flood or drought, NO in between. Earth adapts to where it is. Wild plants and trees adapt. Count on a yearly total, not just any one season. Wild things survive. Man made stuff suffers. Not as strong as wild nature. Climate scientist I read from 20 yrs ago now,,before Global Warming-Climate Change, said earth was heading into extremes as far as weather world wide. I believe he was right on. I know has been extremes forever, but he said this would be above average tough. Think he was right.As a general rule though,,,,Each Summer active part of the jet stream move north. Heat builds up to the south. Heat domes dominate the south with little active weather or sporadic rains. More consistent rain and storms move north twards Canadian Border. Some years the jets linger around Iowa-Southern Iowa,,like last Summer. This year when June began Active Jet raced right up to Minn and Wis, and is diving across the Eastern Half of the US. Iowa is being dominated by hot high pressure. You don't get much water otta hot High Pressure. Typically this pattern comes later in July and Aug to Iowa. We are either in for a long lot more of this,,or if the jet stream dips twards us,,relief! But that typically does not happen until late fall.
