Jeez, it’s in the teens back in western portions of SD. Can’t help but think if some of that CIN could erode that this could turn into quite the tornado event tonight. I don’t envy these mets calling warnings, line is moving so so fast every scan is crucial

Agreed! Was thinking about this exactly, the mainline is pretty much a Cat 1 Hurricane

* Severe Thunderstorm Warning for... Webster County in south central Nebraska... Adams County in south central Nebraska... Southwestern Hamilton County in south central Nebraska... Buffalo County in south central Nebraska... Hall County in south central Nebraska... Clay County in south central Nebraska... Western Nuckolls County in south central Nebraska... Eastern Franklin County in south central Nebraska... Northeastern Phelps County in south central Nebraska... Kearney County in south central Nebraska... Southwestern Merrick County in central Nebraska... Eastern Sherman County in central Nebraska... Howard County in central Nebraska... * Until 215 PM CST. * At 120 PM CST, severe thunderstorms were located along a line extending from 8 miles south of Elm Creek to near Hildreth to 10 miles south of Franklin, moving northeast at 85 mph.

Quite possibly the most absurd setup I've ever seen. Wild parameters (Storm motions of 80 mph, LCL's super low, great helicity, lapse rates at 9°) combined with a frickin snowpack

Foundations can usually are built to handle 4,000 PSI

It really speaks for itself how violent this tornado really was. It’s been 8 years since we’ve had an EF5 in the United States, so the fact it seems like a slam dunk is very telling. I’d compare this a lot with Greensburg though, especially with the rail car damage

One thing that stuck out to me while following the mesoanalysis that night was how the cap eroded perfectly ahead of the storm like a police escort. Pretty much everything to the north and east couldn’t get surface based and nothing fired up to its immediate south. The storm essentially had free reign until the main line caught it in a very moist, extreme helicity environment. I can’t really recall ever seeing anything exactly like this

The roar man…

The damage on TWC right now is unreal. That town of Mayfield is gone

Two large tornadoes that could come into play soon for Owensboro and Clarksville. While the big one may be on its last legs, these two definitely are not. Instability is still there and SRH is off the charts now as the pressure continues to fall with this deepening low. Just an absurd environment

I don’t think this tornado has weakened as much as folks think. It’s in a bit of a radar hole and still posting a solid couplet

Was going to post this. Louisville is going to be under the gun around 1:30 Eastern and the SPC believes if anything that the atmosphere is only going to ripen ahead of this

My thoughts exactly. Regardless of if there was some lift at all, we’re looking at a damage path of 150-200 miles. The emergency response is going to have to be incredible here for so many affected. Hopefully they can get Paducah’s radar back, there are still some strong supercells off to the west

If I’m not mistaken, this is probably the longest track tornado ever at this point

Probably need to send the National Guard in ASAP. Another town wiped out there in Princeton…

What’s horrifying is that this low is deepening and SRH levels across the region are rising considerably. LCL by and large is only 600 meters as well. In all honesty, this is the best environment of the evening currently

I’ve never seen this much debris falling out on a radar. Until that main line catches up, this thing is going to continue to be violent. Absolutely amazing how long this has gone unimpeded by neighboring storms

I feel like I’m watching Greensburg all over again

Worse thing I’ve seen in a long time. That town just got wiped out

KY/IN storms clearly battling CIN at the moment. Not a very robust look outside of the long tracker that just entered the state

Not the most impressive reflectivity considering the CC drop

Some CIN ahead in Kentucky could be the dagger

That thing is incredibly violent at the moment. And the environment is just perfect. SPC has a discussion about it

And it’s in a little bit of a radar hole as well. That structure looks as good as ever

Just wow at the scope of this outbreak currently. Talk about a big dog cell north of Memphis
