I believe that this is simply a miller A that bombs out too late for us. The current GFS and Icon have a low pressure off the coast south of NC. This is due to a SS and NS component that phases too late. This picture of the 6z GFS shows how it is a miller A due to the low off the coast and no miller B element.
Definitely, the way the radar is lined up we seem to at the very least have some sort of precipitation moving in when most models predicted nothing, if only it could arrive 8 hours earlier or later or it just be a bit colder out.
Looks like the bottom energy goes neutral tilt while the second piece of energy dives in behind it at a positive tilt and then phases with the first thing turning the whole system positive tilt. I think that’s what happens at least if anyone smarter than me wants to correct me please do.
