Looks like capping around 500mb and quite a bit of dry air aloft may be big inhibitors tomorrow say south of the Pike.
I'm leaning towards a scenario tomorrow where we see discrete supercells develop across eastern NY and move into VT, MA, and NH with activity organizing into a line towards eastern sections. The forcing is really tied into the strong shortwave with not much frontal forcing (no real cold front pushing east). Given the degree of wind shear, both speed and directional, the degree of forcing we will have should favor a discrete storm mode. There may be enhanced forcing farther east (sea-breeze) which may help activity consolidate some.
I am very uncertain as to what to expect south into CT, but I think the seabreeze front should act least act as a initiator.
