Discussion
Several ingredients will come together later today and early tonight to produce the chance of severe thunderstorm activity in the Mid-Atlantic region. The combination of an approaching cool front, higher heat and humidity, a strong low-level jet, and a vigorous upper-level trough will result in showers and thunderstorms from later this afternoon into the late evening hours and any storm can reach severe levels with potential damaging wind gusts, heavy rainfall, and large hail. In addition, strong wind shear is expected to develop in this environment and this ingredient can result in isolated tornadoes; especially, across the northern Mid-Atlantic regions of NE PA and NW NJ. The surface cool front will move offshore by early tomorrow morning paving the way for lowering humidity levels on Thursday to go along with decreasing cloud cover. Another cool front can bring somewhat of a repeat performance of this type of weather on Saturday night and Sunday with the chance of additional showers and strong-to-severe thunderstorms.
