Honestly I think this setup has everything going for it except for somewhat sub-ideal moisture trajectories due to that pesky ridge centered just off the Atlantic coast, and wind profiles a little more parallel to the cold front that I would like to see across the northern end of the threat. Still, I think the potential is there for widespread wind and hail from Iowa to Oklahoma, with 1 or 2 potentially dangerous tornadic supercells primarily over E KS or W MO. This event could approach, but probably not match or exceed, last Tuesday in magnitude. Following severe weather over the last few years, I've become a big fan of lapse rates/cold air aloft.
Absolutely excellent forecast there. Gonna have to see how things evolve over SW MO/NW AR but you have nailed it.
