The featured chart presents the max daily high, min daily low, and range between the two temperature each April for Ames. A simple long term average is plotted for all three values and this year's data comes in remarkable close to average for all three! The present forecast does not have much hope for challenging the high of 83, but perhaps Saturday night will take a run at the low of 21. The red line represents a trailing 30 year average and there's not much trend to be seen for these metrics.
