Severe Threat May 15-16, 2025

This is interesting.

This is interesting.

That's like one of those descriptions out of tornadoes from older Storm Data or Monthly Weather Review reports, where someone implies that it wasn't 'on the ground' saying instead it was 'at treetop level'. As I mentioned with respect to the 27 April 2011 Trenton tornado, what actually counts as a path break after which it's a new tornado? Can tornadoes skip again?

What I'm curious about is was it still doing damage during that time? Because funnels can decondense, but a lack of damage in that area would in fact mean it lifted.

First EF4 di’s added to the London tornado. But for damage nearer to somerset. Between the two towns.

Glad they upgraded this one because the structural+contextual damage is certainly indicative of EF4 winds.

One of the subdivisions that got hit that is west of I75 in London are still without DIs. I’ll be interested to see if those yield any additional EF4 damage points if they upload them.

They will, the explicitly said in their PNS that they found EF4 damage in the Sunshine Hills subdivision.

They said they are still finalizing dozen’s of DI’s from that area. So It’s still in a wip state.

The Somerset tornado's path is now viewable on Sentinel, showing quite clearly it was wider between the two towns:



Some interesting apparent terrain influence on the tree blowdown:



The Marion tornado's path is also visible, but not so marked:

St. Louis tornado one of the costliest of all time now. 1.6 Billion dollars in damage.

More di’s are being added to the London tornado once again.

I’m very impressed with the London survey. It’s very well done and executed.

And they are taking their time with it, definitely another thing you love to see

 

[tornado examiner]

There it is. The first EF3 di’s in the slabbed subdivision. Slowly filling in.

 

[tornado examiner]

First EF4 di has been added to the subdivision. A low rise church building that was slabbed.
And another one.

 

[tornado examiner]

Wow. Some of these homes must have been surprisingly well built if they’re being rated EF4 with some interior walls left standing.

 

[Ozonelayer]

Absolutly an unbelievable day that was. 2 EF-4s and multiple significant tornadoes.

One thing I noticed is the ratio of the tornado ratings.

2 EF-4s
3 EF-3s
11 EF-2s
24 EF-1s
15 EF-0s

Why do I bring this up? Its because for the amount of tornadoes there were, the amount of intense tornadoes (EF-3+) was quite high. It seems like any storm that did produce on the 16th either produced a brief rope tornado or a strong to violent tornado.

Seems like to me going through the Ef4 DIs, that the surveyors went upper bound with DOD8.

The photos attached to the DIs show houses made from a brick facade, the bricks are filled in with concrete, so not hollow.
There’s some anchor bolts as well, considering how long it took to but these out, it’s safe to assume the surveyors did their homework and went with Ef4 despite some walls still standing.

 

[tornado examiner]

Incredible survey. As close to perfect as you can get. Definitely giving nws Jackson Kentucky a high surveying rating.

 

[SouthFLwx]

not surprised the slabbed church got an EF4 rating. Seems to be the highest DI so far, so I'm curious as to see what many of slabbed homes got.
