A couple of quick things:
The latest high resolution guidance suggests that there will be little if any substantial convection near/south of I-40 in Oklahoma through midday Monday. This is an alarming trend, which leads the latest 00z HRRR to break out numerous supercells (likely tornadic) across the warm sector and near the warm front in the afternoon.
In fact, the HRRR shows a relatively discrete/semi-discrete storm mode in most of the risk area through early Monday evening. Taken verbatim, this run would suggest, in my opinion, a higher-end, regional, as opposed to localized, tornado outbreak.
Also, there is increasing confidence in the potential for a few tornadoes as far east as Arkansas during the afternoon as well. Local climatology with a warm front near the Arkansas River Valley suggests that there will be sharply backed, channeled, flow in the vicinity of I-40. For example, winds will probably be out of the SE, if not ESE, in this area. This would locally enlarge low-level hodographs and could lead to a few tornadoes there as well. I don't think many will choose to chase there, unless they live locally, but in my view, Arkansas is under a tornado threat, too.
