Here is your back bent WF on euro. Goes from center of H7 low and curls near ack and off Chatham. Can see that on the kinks of the height lines.
on the 3k Nam check out that moisture train feeding into SNE. The real mid level dynamics verbatim on this snap shot are in NJ, but that is a pure gravy train on the 3k Nam. Eventually you do get the mid level forcing, but with such a deep cutoff…that moisture train looks impressive.
it’s just something I noticed. There will still be deformation bands etc.
