[Michael O'Keeffe]

Brandon Green streaming a large tornado west of Amarillo, TX!

Edit: Just lifted but a large cone tornado was just on the ground near I40.

AMA radar have strong rotation west of Bushland just south of I-40.

 

[Chris Nuttall]

Both the reflectivity and storm-relative velocities from KAMA were very impressive between 0007z and 0011z. It's got to be mess trying to spot or chase on that thing. It's clearly wrapping up in rain. Velocity couplet remains impressive.

 

[Jeff Duda]

Velocities and shape now really losing magnitude. Either the storm is weakening or cycling. Looking at KAMA's VAD wind profile, the storm must've ingested some localized horizontal vorticity from the showers/convection to the west that merged with the storm just as the rotation flared up.

ADD: Wow, between the 0016Z and 0024Z volume scans the rotation/couplet just completely disappeared.

TWC finest Cantore was going on saying it was a wedge ...then Brandon doing a phoner burst his bubble by saying it was 100 yds. wide.

Looks like the storm's inflow may have gotten choked off by all of the other convection that it ingested.

I got off the phone with Bary Nusz, who said it got pretty "beefy" for a bit. He added that he did get some high contrast video.

Wes Luginbyhl on tornadovideos.net is streaming some absolutely amazing structure! It went from a mess to to a picturesque in minutes!

[Scott Weberpal]

Looks like its wrapping up again just west of Canyon. What amazing structure!

 

[Chris Nuttall]

It appears to be wrapping up again just N of Umbarger on US-60. It's still a bit broad, but it does have some nice vertical continuity.

EDIT: Nice reflectivity ball just appeared in the time I posted.

 

[Jeff Duda]

This new storm has a huge TBSS on it on the 0045UTC volume scan all the way from 0.5 to about 10.1 degree tilts!
