Hurri... uh... landcane?

There's no quick-and-easy name for it, but a large, impressive cluster of thunderstorms evolved into this mesoscale cyclone over Texas during the evening of April 23rd. Note the ring of intense convection with a relative lull in the center. A tornado warning was issued for this churning mess, as winds above the surface were rotating quite briskly around the center point. The scale of this feature is quite a bit larger than a typical mesocyclone associated with a rotating supercell thunderstorm.

To liken this to a hurricane would be inaccurate; however, it's possible that a process that causes tropical cyclones to deepen -- latent heat released from condensation -- helped produce this feature.
