To my eye, the upper dynamics of the system still doesn't mesh with the surface picture the models are putting out. I would think that a system with a jet streak like this
Should have a more consolidated vort field than this
My guess would be that the remnant jet over Wisconsin on Wednesday develops just enough to muddy the axis and delay the main jet from consolidating. But if you look at the strength of the two streaks, you'd think the southern one would be bullying the northern. Not the other way around.
