Severe Weather Threat 5/19-5/22/2024

Estimated winds from VROT and TDS.

Reported is the wrong word. Estimated.

Not sure I follow. The fourth chart in the tweet (probability density function) actually suggests winds are far more likely to be under 200mph. The third chart denotes this tornado had a Vrot of 80kts, also not directly suggestive of 200mph.

I thought that said 190

I believe that means the only analog that his database could return was the Washington, IL tornado from 11.17.2013, which had estimated peak winds of 190mph.

Allegedly footage from Greenfield via Jason Parkin. Damage looks severe.

Let's not turn this into an EF scale debate while the event is still ongoing, btw.

Meanwhile, a storm just south of the Kansas City area (Kansas/Missouri border) just went tornado-warned:

Just saw a chaser on Twitter complain they missed the Greenfield tornado about 10 minutes after it wiped out a town and I think I'm going to pull my hair out now.

Events like this make some people show their true colors. Some chasers are in it solely for the thrill, and for themselves. But I don't want to stray too off-topic now...

Notable hook over Stanhope, IA.

Tornado warning for the Des Moines radar.

Greenfield Hospital took a direct hit.

This is not for any discussion regarding tornado intensity, but insane nonetheless.

Nasty motion, looks like it was intense almost from the very beginning. Not surprising, as the TDS deepened pretty quickly after it touched down.

 

[jiharris0220]

It would be nice to have no fatalities out of this.

 

[TornadoFan]

Got pre-frontal cells starting to form NE of Des Moines.

It would be nice to have no fatalities out of this.

Granulation?

 

[vanni9283]

Ryan Hall's stream suggested 210+ mph winds were recorded at around 600 feet about the surface. That has to be at least 190 at ground level.

 

[TornadoFan]

There might be something going on near Martensdale, IA.

 

[warneagle]

TWC is reporting at least one fatality in IA. Doesn’t say where exactly.

 

[TornadoFan17]

There might be something going on near Martinsdale, IA.

Ryan Hall's stream suggested 210+ mph winds were recorded at around 600 feet about the surface. That has to be at least 190 at ground level.

215mph INBOUND winds, they didn't even include outbound winds in the calculation.
Also, likely twins just NE of Martensdale IA.
