7z,8z, and 9z runs of the HRRR are remarkably consistent with a supercell over the OKC metro. Even with no tornadoes, large hail could make a huge mess where that tracks. A thing to note is that the 07z HRRR is a degreee or 2 high with dews over parts of south central Texas at 11z. This is corrected by the 09z run. It has been consistent with dew points in Oklahoma as of 11z.
