3.1 Zones 4/5/6 (SE PA, S/C NJ) Severe Weather Update
A low pressure system will drive into the Great Lakes today, with warm air surging into the region from the southwest. This warm air has already arrived, with temperatures much above normal for this time of year. As a cold front moves towards the region later today and tonight, the combination of this warm air and plenty of wind shear in the atmosphere will lead to the potential for strong and severe thunderstorms. The wind shear in particular is impressive and could lead to the potential for strong, damaging winds in thunderstorms.
