I find it highly likely they’re gearing up for an upgrade… let’s not jump to conclusions until they make a definitive statement. I’ve been on the train of this deserving at least 190 EF4 based on the RV/contextuals for a while now. If there’s a shot that a home could receive a UB slab swept clean rating, too, that adds even more argument to this receiving EF5.
Literally everyone is impressed by the damage this tornado did - the surveyors, the meteorologists, even the traditionally and infamously conservative minded people who know what they’re talking about when it comes to tornado damage, both inside and outside of this forum. I see no reason for them to rationally stick with a low end EF4 rating here, it goes against every hint they’ve given. You can tell they really want to upgrade this and they’re looking for a reason why. I would be completely mindblown if they didn’t eventually upgrade this. Wouldn’t be surprised if it took a while, though.
