My. Holly noted that the severe strongly depended on what happens with the weakening MCS.
It's already 1230 and showers are still affecting the area and will continue to do so. Greatest threat will be SE PA, southern third of NJ. Threats dead north of there IMO.
If you check out the instability parameters (CAPE, Shear, Supercell) they are targeting SNJ, SE PA. Some of that may affect N&E but not enough to help us.
