While windy, Monday turned out to be a warm day for early May with highs into the 70s. The featured chart presents the year to date accumulated number of days with a high temperature of at least the given threshold for Des Moines. The orange bars represent the 2024 totals with the yellow dots representing an average value. The fewest days on record is denoted by the triangle and most by the full blue bar. The year of the max value is labelled. For values below 70 degrees on this chart, this year has seen plenty more days than average. For days above 80, we are much closer to average. This is certainly a good time of year to have extra warmth to help vegetation and crops get established and avoid chilly conditions.
