A lesser known, less widespread, but even more impressive snowfall hit May 21st 22nd 1883. It is by far the latest measurable snowfall Detroit. It appears that the accumulating snow was confined to Southeast Michigan and Ohio. Reports include 5" at Detroit, 3" at Toledo, and 1.5" at Cincinnati. Due to this being in the early days of weather records there is not too much written about the storm other than what was the newspaper's, but it was noted that the snow did cause damage to the fully leafed trees.
Detroits top 10 largest post-Apr 20 snowfalls on record...140 years of record...indeed this could be historic.
