Mother Nature always has cruel surprises. Intense tornado just hit Hillsdale, KS.

The main cause of this is deviant, inflated LLJ hodographs leading to unusual and cyclic tornadic behavior. Today is as classic as it gets for such nasty surprises. Pray or hope for them.

The fact that SPC can now do MCD's like 411 is absolutely incredible!

The most volatile kinematics were always there in Kansas. It was the initiation of convection that was the problem.
At the time even just 10 hours ago it looked unlikely that anything would initiate due to a stout inversion and nebulous forcing. Only the 3km NAM had initiation in Kansas and I even said it was out for lunch.
The moment I saw a CMU field and looked at Skew T however I knew we were in for very rude reality and unfortunately that seems to be the case.

Mound City is also probably still on the ground.

The storm dynamics are truly incredible right now. BWER developing North of the main circulation and is anticyclonic????

I know this isn't really relevant to the current threat, but the 0z hrrr run seems to have nothing really impact northern illinois tomorrow. it all seems like its gonna be a southern wisconsin threat. I wonder how that'll change things.

It's acting like a hurricane almost now with sporadic meaovortices.

I can only think of 4/19/23 as a analog for this. Deviant LLJ. Weird storm interactions. Classic night on the Plains dynamics-wise

I’m about 85 miles south/southeast of the southern most KS earnings and for almost 9:00, the winds are ripping out of the SE.

Also, just a classic thunderhead. Huge anvil, with a monster updraft and constant lightning. Really, really impressive.

Yeah I think we can safely call the Mound Ciry-Pleasanton an intense to possibly violent and long tracked tornado

Why’s that?

 

[Ozonelayer]

Why’s that?

Well for starters there was an intense CC and couplet for atleast few scans and I don't think it ever lifted

 

[ThatGuy;P]

these Kansas storms are making me think of Union City from a month ago- Unpredicted storms outside of the main tornado threat with likely significant tornadoes- except these are worse as there are TWO cells producing tornadoes.

Absolutely wild. The KC area wasn’t even under a general thunderstorm risk this morning. Stunning miss by the SPC.

It's getting quite late for me, so I'm going to go ahead and call it a night so that I'm ready for tomorrow. In the meantime, I hope that things calm down over the rest of the night!

Has there ever been an instance of this happening? We’ve had significant to even intense tornadoes before in a general thunderstorm risk area, but I don’t recall ever seeing this happen in area that had NO RISK AT ALL. That’s absolutely insane!
