Honestly not impressed by CAPE values at this point. First sniff of the NAM came in even less than the GFS. Think a forced squall line with damaging winds, maybe a few embedded tornadoes in the most likely outcome.
The NAM is probably lowballing surface temperatures a bit in the warm sector looking at the models that also have relatively solid cloud cover getting them to 72-74˚F, with the NAM holding them at 68-70˚F. I have a hard time believing temperatures aren't going to rise at least a bit Saturday afternoon from 12z given the strong southerly flow in the warm sector.
One thing to take away from the NAM though, adding southerly/slightly backed surface winds (like what should happen in this scenario) to this is making the low level hodographs very large.
