Let's see how close this gets to what they put out on the 13z outlook. What's been announced in NWSchat sounds like very similar placement.Based on everything I've seen overnight and early this morning, if I was the SPC forecaster on desk for the 13z outlook this morning, these are the slight expansions and the risk upgrade I would be making:

Consistent signal for violence in north-central Oklahoma starting around 4-5pm and then ramping up after 6-7pm (meaning the updrafts also get rooted at the sfc before the nocturnal inversion develops). Also seeing a concerning signal for a tail-end charlie on the southern side of the Kansas QLCS that may be a supercell with violent tornado potential on the southern end.... near or south of the Wichita metro, and probably starting a bit sooner than the OK threat.
Very deeply and gravely concerned by the consistent HRRR depiction of that lead supercell in the OK cluster putting down a mesoscale boundary for the following long-track supercells to ride along in a synoptic background environment that's already very supportive of long-lived EF4+ tornadoes...
