There was a bit of one (not as dramatic as Mayfield) for a couple of scans with the violent tornado in the northwest Omaha metro today, but it was somewhat masked by a convective cell just south of the tornado getting ready to merge into the updraft. At around the time that was happening, reflectivity in the debris ball was around 70+ dbz and delta-v was 230+ mph, all 500-750 ft above ground level.

Yeah I’d be surprised if that one weren’t at least high end EF3

TBSS on this storm… and I’m not sure it’s from hail.

Jeez, that's absolutely insane...

Big tor just east of Creston, IA.

The southern storm near grand river had significant rotation.

The southern storm near grand river had significant rotation.

Looks significant but it’s so far from the radar that it’s hard to tell much

 

[Tennie]

Has there been any word on casuality counts (preferably confirmed) yet?

 

[TornadoFan]

The models were pretty spot on for today.

The winterset storm really looks like it’s gonna try as it heads for Des Moines

 

[warneagle]

Might be outrunning the best thermos but the kinematics ahead of these storms are very impressive still.

 

[TheSuckZone]

Velocities have really started coming down in intensity other than the brief cell mergers

There was a good case study video Trey did on the 3/2/2012 outbreak and noted how the West Liberty tornado moved outside the warm sector that was in KY into a more hostile thermodynamically environment in West Virginia. The storm was able to maintain a while longer based on the insane shear parameters but once a supercell is built up and mature it’s hard for it to stop and can take time to weaken in circumstances.

Velocities are increasing on cell in SW Des Moines metro

edit = now warned

True but we’re getting into a messier storm mode so that might mitigate their ability to continue to propagate. Translate? I can never keep those straight.

Connor Croff had what looked like a funnel near St Charles
