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

[Shakespeare 2016]

whoops, wrong time.

I think is safe to say that the damage is at least EF4.

 

[Maxis_s]

Based on this, I'm inclined to agree

Plus based on the DOW data which showed likely EF-5 intensity windspeeds before entering the town.

That 1 fatality is in Adams county, not sure if same tornado as greenfield?

Apparently a photo of the pavement scouring, combined with extreme tree debarking.

I’m not sure, this seems like it was already pretty bare before the tornado hit.

That's where the tornado first touched down, but Greenfield is in Adair County.

Manhole covers and pavement reported ripped from the ground in Greenfield.

That was used as an EF5 indicator in Joplin iirc

Perfect timing for there to be an event keeping me at work until 8 pm

That's where the tornado first touched down, but Greenfield is in Adair County.

I doubt this will continue, but I'm glad there has yet to be any reported fatalities in Greenfield.

Still haven’t heard anything from the Cambridge, Iowa area. Where the tornado was moving at 85mph

If it is rated EF3+, it will record the fastest ground speed ever by a violent tornado, overtaking the 1925 Tri-State tornado.

Pilger Nebraska 2014 is that record holder…violent tornado had a forward speed of 94 mph near the end of its life.

The tornado watch in Missouri/kansas/oklahoma/Arkansas has really underperformed so far.

Wind fields weren't as impressive in MO but that can change as shear picks up towards dark if some cells are still discrete

 

[Austin Dawg]

I just saw an aerial shot in Greenfield. It's easy for it to make EF3. They will have to look on the ground to see if it deserves any higher, but it really is catastrophic. It has about a quarter-mile central pathway of complete devastation.

I’m not necessarily talking from a tornado point of view, the SPC really built up the hail threat and it just hasn’t materialized

Things have kind of hit a lull. Wondering if the LLJ will put things back in play.

Stable air loading.

Different country, but here in Ontario we just got the loudest thunderstorm I've ever heard. Constant rumbling from lightning, it sounded like a jet engine.

 

[jiharris0220]

Perhaps a strong rotation in the line segment.
