I've never seen one of these Miller B transfer types in my location, so will be interesting here. The more amped it is, the more it really wants to run an 850 circulation up the eastern valley.
Nam out to hour 27 could be better confluence, and the vort is moving a hair faster. But there could also have just been a high flying Sandhill crane fart in the wrong direction.
I'm curious as to how it is showing an ice storm for central and N. east TN with that track. Is it downsloping the midlevels, but locking low level cold air in? I hate ice, but meteorologically that would be something to see.
