Am I seeing two seperate rotations on it?

That's what I was wondering. One potentially just East of Defiance and another basically splitting Defiance and Irwin.

 

[tornado examiner]

Exactly

 

[Tanner]

Yes there it is two rotations. Western one is occluding and the eastern one is forming.

Instability is not just about what is at the surface. It's 100% about the vertical distribution of those factors with height through the column of the troposphere. 500mb temperatures are -15C and colder in the supercell outbreak area up there. There have been instances in Iowa specifically with F3-F4 long-track tornadoes with surface temperatures in the upper 50s. Despite the surface observations as they are, mesoanalysis still shows 1500-2500 j/kg of SBCAPE nosing up into a good bit of southwestern Iowa and southeastern Nebraska.

I know there have been cooler temperatures for violent tornadoes but that usually happens in the early season. Though it does happen later in the tornado season it just seems more rarer.

Rich Hill, MO storm is really looking impressive.

 

[Tempestas Tonitrua]

Those cells back building from the Missouri tornado warned cell into Kansas need to be watched

 

[TornadoFan]

Iowa storm is back on the ground..

 

[TornadoFan]

Brad Arnold has a huge wedge on his stream.

 

[TornadoFan]

Stream of the new Iowa tornado. Still very large and dangerous.

Great minds think alike.

Great minds think alike.

Deleted it for redundancy's sake.

[TornadoFan17]

Stream isn't great for seeing it currently but the tornado is rain-wrapped. Still very much on the ground.

 

[TornadoFan17]

71 TOR reports for the day and counting...

 

[andyhb]

This looks high end. EF3-4 range.

 

[warneagle]

This looks high end. EF3-4 range.

Definitely tracks with the ~20,000 ft debris lofting in that area.
