I have a question about Tri state tornado. While we all know it maintained violent intensity all through its life. Where it most likely peaked its intensity based on the damage information we have? For Mayfield we know it's probably near Bremen.Probably not a huge number since this event received pretty thorough coverage, but no doubt there were some. Two of the deaths I mapped in Missouri were seriously injured people who died weeks later (nearly three months later in one case) but don't seem to have been officially counted. Occasionally there are also people who are counted who shouldn't be, like the woman who died of a heart attack near Alliance, MO despite the tornado missing her house by almost half a mile. Overall though, the death toll is probably somewhat higher than reported.
Regarding the size/appearance, in reality it probably fluctuated quite a bit across Missouri due to the influence of rugged terrain (think Moshannon and some of the other 5/31/85 tornadoes). Those kinds of details get lost without things like satellite/aerial imagery, but it probably accounts for why there are conflicting details from the same general areas. For instance, a few different people estimated the path width near Schalls/Brazeau at between 3/4 and 1 mi, while a couple of others estimated it at between 1/4 and 1/2 mi. In reality, it's entirely possible they're both correct(-ish) and they're just talking about slightly different locations where terrain interactions changed the tornado's structure.
As for the 235 mile length, that was using the endpoint SSE of Petersburg, IN. We now know that was a separate tornado - several people saw it lift, travel aloft a short distance and then touch down again. There was also a small neighborhood directly in between the endpoint of the Tri-State and the touchdown point of the next tornado that recorded no damage.
I'd almost bet there were other undocumented tornadoes as well, but I haven't had time to dig into it yet.
