I am not the EdM who runs that web page.
Kocin and Uccellini rank it one of only 9 storms awarded a top tier Cat 4 or Cat 5 snowstorm rating (Crippling or Extreme). A Cat 4, like the famous 1888 Blizzard.

UK or Ohio Valley "Blizzard of 78" (checked Google) memories also most welcome, even if not my blizzard.
