Early April can be a frustrating time in Iowa as a long cold season has everyone ready for great spring weather, but chilly temperatures are still quite possible and the growing season is not fully started yet. The near term forecast has daily high temperatures mostly in the 50s for the next number of days, so today's featured chart looks into which months have the highest frequency of such days for Ames. It turns out that April has the highest frequency of such days, but you notice a rapid drop off for May and the frequency is basically zero for the summer months of June through August.
