Pretty good case to be made that both the 1920 and 1965 Palm Sunday outbreaks should be considered super outbreaks, especially if you account for the low-balling of the official numbers with older events. Palm Sunday '65 officially has the second-most violent tornadoes (18) of any outbreak, of course. Palm Sunday '20 officially has "only" eight violent, but at least four others caused damage that probably could (should?) have been rated as violent, and several of the official F4s were actually families of multiple violent tornadoes. Not to mention the geographical extent of the outbreak, with violent tornadoes occurring as far north as the Tri-Cities area of Michigan and as far south as Central Alabama.Yeah the Coldwater tornadoes produced some of the most violent damage in Michigan history imo.
Honestly, I feel like the only reason Palm Sunday isn’t really considered a “super” outbreak is due to a lack of F5 ratings, despite multiple tornadoes that produced obvious F5 damage. There were also probably numerous F0s and F1s that were never confirmed, and the total number of tornadoes that occurred that day is almost certainly higher that what is documented. It was by all indications on par with, or at least close to a 4/3/1974 or 4/27/2011 type of event.
