Odd part is moisture is a good bit north of 18z. Confluence in the northeast also not as great this go around. The back end energy seems to want to affect the storm this go around. A lot of different moving parts for sure here.
One thing I see and notice now is the energy up on the Dakota/Canada border seems to be taller and a tad more displaced westward, which I guess in theory would affect the moisture transport, along with a tick less confluence up north.
