Recent Seasonal Snowfall Totals - Northern Ohio/Midwest/US - Part II

We start the snowfall retrospective with last winter's (2019-2020) snow totals in northern Ohio.

Last year was the 5th straight year with below normal snowfall. The longest stretch of below normal seasonal snowfall was 9 winters between 1963 to 1972. 

Here are the average snowfall totals for northern Ohio. (Color contours are different than the image above)

How about the last 10 winters?  Here are the local snowfall amounts. Colors might be different year to year.













Last year's running snowfall accumulations really tell the story when compared to other years.  (Hat tip to Jared Rennie for supplying these snowfall graphics below)
