Up until this point, there's been nothing to force convective development south of I-40
That said, I would still keep an eye out on the Lawton and Wichita Falls area for more discrete development over the next couple of hours, especially with the actual jet streak moving in.
NWS Norman seems to be on a similar wavelength, because they're now thinking the best timing for severe weather in OKC and southward is between 11pm and 1am.
