By the way, I think the violence of this outbreak is underrated. I'll have to check my notes after work but several F3s were probably F4. And of course, Atlantic (which devastated an Amish community) was so ferocious.

I wouldn't be surprised if the Moshannon Forest F4 was the strongest of the outbreak.

I've no doubt the Barrie F4 was actually an F5 after seeing enough damage pics from it, one of the few verifiable F5s outside of the USA. Kane, Tionesta Atlantic & Moshannon were easily F5s they just didn't hit anything capable of registering it. Sometimes I wonder if the Kane F4 was actually stronger than the Moshannon Forest F4, if only briefly when it went through the Tionesta Scenic Area.

I'd have to go back through the thread, but Loco's damage pics from Atlantic, Tionesta, and Kane are all extremely impressive.
 
Someone else here asked if a similar outbreak would ever be possible in this state again.

I really wouldn't like to see more analysis of the 1944 Appalachians outbreak and, a real obscure one, the 5/2/1929 outbreak


That dropped multiple significant tornadoes east of the Blue Ridge in Maryland and Virginia. I live just north of the affected areas in Maryland. This area RARELY gets significant tornadoes- as in, less than western Pennsylvania. Information on either outbreak is scanty

That’s (iirc) the only tornado outbreak to kill people in downtown Columbus, Ohio. The ‘71 and ‘73 tornadoes didn’t move through that area.

I agree with corree photo
 
hey i found someone on x posted about this with the new episode on the december 9th 2023 tornado outbreak including a bunch of other documentaries as well for both season 1 and season 2 you do have to sign in or choose your tv provider if you are planning on watching just to let everybody know
 
Of any tornado event in history, the 2019 Dallas-Richardson EF3 is 100% the most menacing tornado I've ever seen photographed. Sure, Tuscaloosa was hellish, but there's something about a giant nocturnal stovepipe over a populated area that does it for me.

As for Niles wedging out, it has a max width of ~450 yards according to Highways and Hailstones, so there's a chance it remained as a drillbit for most, if not all, of its life.

450 yards is over quarter of a mile wide, so not exactly "drillbit" at some points. It was around half a mile wide when it hit Wheatland:


It was pretty large at certain points in its life.
 
I wouldn't be surprised if the Moshannon Forest F4 was the strongest of the outbreak.
The Tionesta F4 is highly underrated with the 1985 outbreak; striking Forest County PA. It was described to sound like: "a thousand locomotives", and was a "Black wall swirling with pieces of houses and appliances.". It transported a check ~140 miles, and reportedly scared wildlife so badly, they refused to reenter the woods, staying on the roads instead. It's very likely the Tionesta F4 was just as, or nearly as strong as Moshannon; which was so intense, that apparently a seismic reading was seen at Penn State as thousands of trees were blended in the F4.

These tornadoes were remarkably intense, and literally may have caused quaking..

I don’t doubt these tornadoes in this outbreak were particularly high-end, with many of them likely powerful enough to have been given an F5 rating if they hit the right (or wrong depending on how you look at it) things. This seismic reading claim is something I’ve heard of before, and I’m not going to lie, I’m very slightly skeptical of it as something that occurred specifically due to the tornado - but at the same time, a coincidental earthquake occurring is exceptionally unlikely as well, especially for that region. I really don’t know what to make of it. If it really was the tornado doing that that’s pretty incredible stuff.
 
Speaking of particularly intense tornadoes with possibly questionable readings - the Sawyerville to Eoline, Alabama tornado on April 27, 2011 had a kinetic energy level of 123 terajoules, which is higher than that of the Smithville and Hackleburg tornadoes (both mentioned in the same study). That’s almost twice as high as the nuclear bombing of Hiroshima.

I wish we had that data; I might look for it later. But I do agree and feel it's natural to be suspicions here; the Tipton EF4 actually had an earthquake mid tornado.
But I actually dont doubt that intense-violent tornadoes do create some variety of ground based shaking; mainly from pressure waves.
