The high temperature for Des Moines hit 101 degrees yesterday, making for the first 100 degree reading since 2006. The featured chart presents the number of days each year the temperature was in triple digits and the highest temperature for that year. The 1980s were the last period of a significant number of these really warm days. Of course, the dust bowl period of the 1930s stand out on this plot as well.
