I've been recently observing severe tornadic supercells move SSE across the Kansas/Oklahoma border, within the slight risk area issued by the SPC.
9:47 PM CDT
Storms continue to pace eastwards in the vicinity of Cherokee, OK. The first supercell of interest appears to be a forming tornado located about 4 miles NW of Medicine Lodge, Kansas. The velocity radar images appear to be indicative of a tornado or mesocyclone in action. The storm is currently under a T-Storm Warning.
The second supercell of interest is about 11 miles southeast of Cherokee, OK and 6 miles SW of Medford, OK. The tornado signature has been fluctuating back and forth between strong and weak, but it appears that the TVS is strengthening again. A strong bow echo is also apparent.
The final and strongest TVS is located 5 miles east of Medford, OK. The storm is under a TORNADO WARNING. The TVS has been a persistent strong signature, keeping itself with a spiral appearance on base velocity radar images. During the past hour the TVS passed directly over the heart of Medford, OK. There may be damage associated with the strong supercell.
9:56 PM CDT
The supercell 6 miles SW of Medford is now strengthening and winds are wrapping around quickly toward a common center. The storm headed for Medicine Lodge is weakening but still remains severe. The Medford tornado is heading eastward with no fluctuation in satellite appeance.
