For all you fellow 4/27 nerds, y'all may be interested - I've found 3 (possibly 4) undocumented tornado scars within the limits of the Black Warrior Wildlife Management Area in Lawrence County. The scars showed up sometime between 2006 and September of 2011, but the rapid cyclic pattern of the two big tornadoes leads me to believe this was on 4/27. The largest one is likely in the EF2+ range, and the other 2/3 are non-significant. One of the three is a satellite. I have a graphic at home made; I'll post it when I'm back on my main PC.

I'm going to reach out to NWS Huntsville (emailed) to see if they can evaluate/potentially confirm these tornadoes. With the recent confirmation of the EF2 near Forkland by BMX I have no doubt they'll add these to the database.

I'm still evaluating radar to see exactly which day these happened, but I'm sure they'll figure it out. The rightmost one is possibly an EF1 that occurred on April 20, 2011, but that track is only 3 miles long, is in a northeast direction, and starts significantly east of where the big one first touched down.

Upon further research I am almost 100% confident that all of these tornadoes took place during a QLCS event on April 20, 2011 (which explains the quick cyclic pattern), with the rightmost one being documented as an EF1. The other 2-3 are completely undocumented, however. The longest-tracked tornado is likely in the high-end EF1 to low-end EF2 range based on treefall and the rest are very weak. I'm not surprised the other 2-3 were missed, as none crossed any roads.

Does this look like two distinct mesocyclones (one to the SW) to y'all? I've already sent BMX the report of the two undocumented funnels captured on Coleman's video as I've found damage likely associated with them (directly E of Aldridge; probably not associated with the morning EF3 although it can't be ruled out), but just double-checking. The main reason these weren't able to be sent in prior to yesterday is that no attempt was made to geolocate Peters/Coleman's video and line up the time they showed up on video with the NWS-made path; lining everything up put them just east of Aldridge, which is where I found damage.

I counted at least four tornadoes spawned to the south of the main tornado, with two having definite damage and one being extremely weak, with only a few trees down. The fourth is a 50/50 as the damage is possibly not tornadic and it wasn't caught on video. None are satellites as all have a visible mesocyclone. Sorry for posting about these undocumented AL tors so much.

i think you mean this video?



theres like 2 tornadoes and a extra funnel in this video , there are a lot of possible gaps with cordova , i believe there were multiple tornadoes.

Nice work, I would consider the Blair Creek Tornado EF3 intensity as it completely flattened the Poplar School. And no words on Gallatin...it is definitely F5 intensity no doubt. (It cycled after TN though).

We 100% have undocumented tornadoes from this outbreak, wonder if you can provide us some. Also Gallatin is F4+ (basically F5)
 
Question about El Reno/Piedmont 2011...

So I've heard it implied a few times that some of the house damage was rated EF5, but the DAT does not reflect this at all. Was there really any EF5 rated structural damage from that tornado at all besides the oil rig? As far as I know, there wasn't but maybe I'm wrong. Also, regarding the infamous "trenched house", is it included on the DAT, where was it located, and was it ever given a rating? Any info on this would be great.

From what I know, El Reno was rated EF5 based off of the damage to the oil rig and no "traditional" EF-5 damage indicators were found (well-built homes swept away). However, if you ask me, I still think the EF5 rating should stand due to the sheer number of homes that were swept away and the fact that it produced some of the most incredible contextual damage every documented.

Yes, a tornado seemed to touch down and damage parts of McLeansboro in Hamilton County Illinois some time later after the tri-state tornado passed a few miles south of the town. A few photos that I have somewhere show damage and one or two homes destroyed.

There was one home north of Piedmont that was relatively new and appeared to be built on a concrete slab foundation, but due to the lack of a ground survey it was given a default rating of EF4/200. While it was plausibly well-built, can't confirm without ground photos unfortunately. (satellite photo was taken post-cleanup, but the DAT entry confirms it was swept by the tornado)

I'm not so sure that's a still of the Bossier City tornado. I know the screencap comes from a KERA-TV (PBS affiliate) segment about the storm in question, but the tendency of major news networks to 'fill in' with stock footage if no actual material is available, always makes me suspect.

With that said, I hope it actually is Bossier City - not just for accuracy's sake, but also because it would be pretty incredible if footage of the actual tornado exists.
 
Speaking of tornadoes I am actually working on annotated maps for those who cannot access the interactive damage path that should be more meaningful than just screenshots of the path like this one below:
1769549588674.png
I actually made one already and posted it here of the tornado at peak width, but have been doing some more. These are only in Franklin& Hamilton County so far. (Red markers indicate complete destruction, yellow is severe damage, green is moderate/light, blue are non damage placements). Places with a black star indicate fatalities with the number of stars representing the number of deaths. Same coding as the interactive path. What is also neat about these annotated ones is that they are overlayed on 1938 aerial photos which would make them far more authentic to the actual 1925 path era than modern google earth is. For those who have read my article which details all these locations it will make a lot more sense. West Frankfort I omitted most damage points on purpose and only put in a few notable places on the annotation.

The level of detail here is extraordinary, man. You never fail to impress me with any post you make, this is incredible documentation

Bumping this guy because he makes fantastic real time reconstruction videos. If you're looking for something similar to Tornado Forensics, this is absolutely what you are looking for. Wonderful documentation and detail of the Jarrell tornado including all footage known from the day

while made well there is some huge inaccuracy with the path map , i just released the damage path online a few moments ago

mine = Black
vs
theoldcallisto = Pink

download link to it , it includes all the damage points as well.
