Significant Tornado Events

It was probably this one that I posted. Several of the terminals were pretty close together (along with some of the industrial plants and whatnot) so there's probably no way to know for sure, but I'm basing my speculations on the apparent locations + the fact that R&J Trucking had its roof torn off mostly in one piece while Yourga's was shredded, which is what it looks like is happening here.

(Edit: Or it might've been the same one, I dunno. I don't remember when I learned about the R&J roof.)

I believe this is probably about the time the tornado was moving into the more residential area around the railroad tracks.

Found this picture of a sheet metal roof on someone's house in Wheatland; not sure which building it was from but definitely looks like the whole sheet metal roof.

Yeah I tried to find out if that was the roof but the photographer didn't remember and no one else could say for sure. Very well could be; it landed over a quarter of a mile away so it would've been outside the main damage path.
 
I just recently learned something new about the Beaver Falls F3 (which I've long considered underrated). It destroyed a place that sells farm machinery in Evans City and allegedly threw/rolled/bounced multiple machines, including a 16000lb tractor, between half and three-quarters of a mile. I wouldn't necessarily take the distances as gospel, but even if it were half that it'd be pretty impressive.

It's hard to tell, but the tornado probably wasn't even at peak intensity in that area.
 
Question for you guys. Has there ever been a violent (F4/EF4) QLCS tornado? I sorta consider Harrisburg, IL 2012 to be one, though one could argue it was an embedded semi-discrete supercell structure. Other than that, I can't really think of anything.

Edit: I'm looking through radar loops of Harrisburg and it doesn't quite meet the criteria. Had a definite cellular component to it, albeit not as classic as Estill.

Estill was not a true QLCS tornado. It was spawned by a semi-discrete supercell structure within a line, and that's an important distinction. I'm talking about a legitimate QLCS spinup that formed along a comma-head, dog leg, or notch along the leading edge of the line, with no cellular component to it. Think El Reno 2019.

One potentially may be the West Bend, WI tornado of 1981, but the low quality radar images I have seen of it aren't very conclusive.

IIRC (which I may not be), the 5/5/99 Linden, TN F4 was spawned by a QLCS that swept through Middle TN.

The 1983 Andover MN F4 might have been spawned by a QLCS

I've heard the same about Huntsville, AL 1989 and West Lafayette, IN 1994, but I believe those also fall into the semi-discrete category like Harrisburg and Estill. I think the closest I can find is West Bend, WI 1981.

One tornado come to my mind was Greenwood Springs MS tornado in 2019. Tornado spawned by QLCS system that rated EF1 but have"EF4-5" potential according to that research. I have some doubt about West Band of whether It can be rated EF4 in today's standard.
 
Just to cheer @Juliett Bravo Kilo up a bit here's the April 20, 1920 map with the April 3rd, 1974 and April 27, 2011 tracks added with the power of tracing.

Did you make this or get it from someone else?
It'd be nice if each track was labelled (like on the older thread) but overall good job to whoever made it. Yeah, both of the Tanner tornadoes of 1974 and Hackleburg-Phil Campbell 2011's paths practically touch at points.

Used Tornado Archive's data viewer. Then used Scratch to draw the April 27 and April 3 tracks, then added them onto the April 20 map.
 
I can only imagine that excellent map showing all the tornadoes- even just the strong ones- which have passed through that area over time.
