Storms have been firing since early this morning along an old outflow boundary/warm front in W NE. Now those storms have progressed southward in to KS and extreme eastern CO and are looking more and more impressive by the minute. Cell in Cheyenne Co., KS (near St. Francis) looks like a supercell moving SSW with the rotation or convergence/divergence signature all the way on the far north side of the storm. Also, another cell to the southeast, currently in Logan and Gove Cos., KS, has taken on a cell-bow echo shape and is dropping an OFB that the first storm is about to intersect. My guess is, when that storm picks up the vorticity from the outflow boundary, it will definitely go tornadic or at least significantly supercellular.
ADDITION: just as I was typing this, the cell in Cheyenne Co. picked up an anticyclonic fish hook shape and is indeed rotating anticyclonically on the northeast side of the storm, yet has a small echo overhang on the southwest side of it with maybe the slightest hint of cyclonic rotation.
SECOND ADDITION: That storm has been showing a gnarly hail spike on it for quite a few scans. It also appears to have turned even more to the southwest after having met with the OFB.
