The initial storm in north TX has, as mentioned, lost its previously supercellular characteristics as the main updraft moved off the dryline. The storms have quickly backbuilt as they continue to work their way through an environment conducive to severe weather, even if the initial supercell is gone. This is quickly pointed out by the latest radar trends which continue to show massive a massive reflectivity core aloft with 65dbz approaching the 36,0000 ft level--quite impressive, as are the VIL's that are pushing the mid and at times upper 70s. Thus the storms appear capable of extremely large hail during the short term.
As I mentioned previously, the LCL's in the storms initial environment appeared to be somewhat high, which is probably what kept it from becoming a real tornado producer (although there was one unconfirmed report of a tornado according to FWD). As of this writing, the storm continues to exhibit at least mid level rotation owing to the 50kts of 0 to 6 km shear the storms are working through, so one would expect the severe threat in the form of hail/winds/and now flooding to continue, although isolated/brief tornadoes would seem to still be possible to some degree, depending on how cold individual RFD's are in the storms.
