After finally getting a period of hot and muggy weather typical for summer in Iowa, our weather has reverted back to pleasant afternoon temperatures. Could we see another day above 90 this year? The featured chart looks at the combination of days above 90 degrees and the last day of the year that had a 90+ degree temperature for Des Moines. The red line represents the accumulated frequency. For example, 40% of the years have had their final 90 degree temperature by 1 September. It will be interesting to see how 2014 finishes on this chart as the total number of days so far has been paltry.
