Some of the damage from that tornado definitely strikes me as EF4. It appears as though it peaked on radar right around Brimfield where at least 2 homes were leveled. A lot of the homes along the path were “sliders” but there’s at least 2 photos that clearly show anchor bolting around the foundation. I don’t have permission to show the other so here’s just 1. The tree damage is probably among some of the most impressive I’ve seen at least in photos. Max V-Rot was ~80-90 kts and a Delta/V of around 150 kts (172 mph). Given that and the damage at the ground it’s most certainly deserving of a lower end EF4. However I wasn’t on the survey.
