Two bad snowstorms that I remember hit on these days:
Christmas Eve 2002 in Cleveland, Ohio 8-12 inches
December 22, 2004 in Cincinnati, Ohio a foot and -3 degrees
The worst part of the second date was the cold. Based on my experience, I would say that this happens every 3-5 years in Cleveland and maybe every 6-9 years in Cincinnati, Ohio.
