The globals had something going on there 360 hour a couple days back, but I'm not akin to this behavior. There's actually a strong Upper level ridge pushing off the east coast as we speak, this will depart and result in a blocky pattern over the east coast. Now according to the GFS, this will prevent any track that would lead to a east coast landfall, and keep it south. By 144 hours the disturbance is already in the leeward islands...I would imagine the shear would be great in an area between two highs, therefore development would be hindered.
