As of 12:42pm EAX radar...

Hook echo with TVS approaching Ionia, MO.

Rotating storms with mesos approaching Harrisonville, MO and Louisburg, KS. The Louisburg storm has exceptional inflow judging from the visible satellite imagery. In this case, it would also be a "tail-end Charley."

Three cells to the north of my house here torn warned,but terrain is very rough to chase.Take cover as these could be rain wrapped!!

 

[Jeff Duda]

Better add AR to the mix. Good looking cell just ESE of Little Rock. Tor warned, and shows decent rotation despite rather marginal shear (both deep layer and low level)

Gorgeous stack of plates look from the small supercell just north of Topeka...no real strong attempts at tornadogenesis, but definitely a well-organized mid-level mesocyclone resulting in picturesque structure!
