The wettest day in Detroit ever was on July 31, 1925, when
4.75" of rain fell within one day. So that was our first thousand
five hundred one hundred or whatever you like storm.
For sure it was a 100 year storm. So then the next 100
year storm would be predicted to occur in 2025.
4.57" fell at Detroit Metro Airport on August 11, 2014,
which qualifies that rainfall as the second highest in one
day for Detroit. That's close enough to 2025 so it can
also be a 100 year storm, following on the heels of the
July 1925 storm plus 100 minus about a decade.
But then...no more storms like it until the year 2114?
