It's hard to believe that it's only been over 100 in Des Moines once in the last 5 years.

I believe 2012 had the 11 days above 100.
And the once in 5 years in Des Moines really isn't surprising. Things go in cycles.
In the 60's it was above 100 just twice the entire decade. Two days! Once in 64' and once in 66'. In the 70's only 1974 and 1977 had days over 100. That's 20 summers with only 4 having days hit the century mark.
Then came the 80's with some of the hottest summers since the 30's. Patterns come.........patterns go.
