With our recent weather featuring steamy conditions and the forecast for July continuing to look very warm as well, it is informative to look back on past average daily high temperatures during summer for Ames as shown by the featured chart. A simple linear trend line is fit to the plot and while it shows a poor fit score, the trend is somewhat negative. It is interesting to notice that recent very warm years (2012 and 1988) were both significant drought years for the state.
