There was one rural home that got rated as 180mph just southwest of town.

Damage in Greenfield is extreme. Hard to say anything else than "slam dunk EF4+" looking at the aftermath photos/videos. There is nothing left standing in the path of that thing.
Worst tornado damage I've seen in Iowa since Parkersburg.

Another Dane County warning, though I'm still out of the polygon, but am moving to the basement. It looks like this line is just going to spin as it moves into the area. The cats will hate me, but so it goes.
Please stay safe out there!

One of the radar operators on Ryan Hall’s stream said a DOW measured 200 MPH towards the surface outside Greenfield.

There were tornado reports from the 1974 outbreak in AL moving much faster than that, supposedly because the thunderstorms grew so tall they actually caught the jet stream flow (85ftk+). One in NW AL supposedly moved at 113 mph. Hurricane Laura generated tornadoes moving 85 mph too. And I think 27 Apr 11 had 90 mph tornadoes.

If I recall that was the Guin parent cell wasn’t it?
Source for the 113 mph? I have a list of average speeds that I copied from table that Fujita made (ironically I now can't find the original) and IIRC none were that fast.
Of course we don't have good measurements for maximum speeds. Some old photogrammetry shows quite dramatic variations in a short tine.

I would like to say EF5 but I see a lack of context and the anchor bolting looks somewhat questionable. 185 OR 190 MPH is what I would say.

Considering that it's rebar I doubt it'll get an official EF5 rating, but still, clearly a violent tornado.

Look on the ABC 3340 Weather Blog & go back to 03-04 Apr, Bill Murray. This was during the 50 anny Superoutbreak discussion. The warning actually stated 120 mph but the tornado actually moved 113.

New warning for a large portion of Dane county, including me! Glad I came down earlier.

Definitely worse than Keoka last year.

PDS SVR for the northwestern corner of IL for 90 mph wind gusts
Don't forget it would need to be built above a standard of construction that apparently is almost never seen anyway.
Because some of the people involved in making the EF scale believed houses shouldn't be EF5 and this unscientific personal whim is apparently more authoritative that Fujita's prescription of a six step scale to be used with houses.

I'd like to point out that only one of these anchor bolts has washers on them. This either means that, well, only some of them had them to begin with, or the tornado was able to rip one of them off of one of the bolts.
