Significant Tornado Events

I’d honestly say a lot of the survey was highballed. Structures that shouldn’t have been rated higher than low-end EF4 were given EF5 ratings. I’m yet to see a single structure in Hackleburg that actually warrants the EF5 rating, although later down it’s path I think it did hit a few EF5-worthy structures.

Wasn’t there a home in Hackleburg that had concrete stem walls sheared off at something like 2-4 inches AGL? I feel like that may have been the only legitimate home in Hackleburg rated EF5.

Here is the RAP reanalysis proximity sounding of the Robinson tornado. I’ve noticed these reanalysis skew Ts can really undercount thermodynamics and instability, so take those measurements with a grain of salt. However, this tornado took place well after dark so instability was decreasing with time.

Definitely high end kinematics, but not even in the ballpark of that thermal boundary area on 4/27/11 where 0-1 KM SRH was reaching up into the 800s,
0-3 SRH a little over 1000, and almost 2000 ML CAPE.

Here is Smithville kinematics. I am not sure that I have seen its equal?
