I think I already addressed this. The velocity was so high there were many touchdowns vs return to wall cloud.

It was the high velocity the professionals weren't used to and were caught in the high energy, water vapor saturated heat storm. I did already state that. But, I also stated the weather service would be analyzing the data and presenting it's findings. They did and have confirmed my own prescription to death and disaster. I don't enjoy those analysis either. The El Reno heat storm did not 'make my day.' Quite the contrary. 

However, this proves without a doubt there is solid science used in measuring these storms to understand the profound changes occurring in our climate.

The tornado (click here) that struck El Reno, Okla., Friday "is officially the widest known tornado in the U.S.," says the National Weather Service office in Norman, Okla., announcing today that at its widest, the storm stretched across 2.6 miles....
...The El Reno tornado's intensity was upgraded to the maximum rating of EF5; the weather agency says its winds reached 295 miles an hour while it was on the ground in the area west of Oklahoma City....

I need to address something, a misuse of the language surrounding these storms. There is a difference between Shelf Cloud and Wall Cloud. If professionals want to be understood by the public they need to be consistent in their use of language.


This is a Wall Cloud. It is unique and only occurs when tornadoes are the prevalent threat. This photo is by NOAA.

Below is a shelf cloud. This one happens to be a thunderstorm. There is a difference. When Wall Clouds are noticed in the area people need to take their safety very seriously. That might be the case with a Shelf Cloud, too, but they do not have the profound danger accompanying Wall Clouds.


Shelf clouds can also result in Roll Clouds. They are all considered Arcus Clouds. They are different from Mammantis Clouds which carry their own prediction capacity.

But, the public likes to be correct in their language and understanding definitions. It empowers them. As a professional the public should have a place in the definition of the practice. Professionals exist because the public values them.
