Sort of two areas of forcing. The stuff near NYC is more synoptic...think H7 and H5 factors like vorticity advection, divergence, deformation etc. Then increasing LLJ and low level frontogenesis off s coast. All the while you have good venting aloft with strengthening jet above 30,000ft. There probably will be an area stiffed, but overall many should have a decent drink. Possibly prolific amounts in a narrow area.
