Several ingredients will come together late today and tonight to raise the chance of severe thunderstorm activity in the Mid-Atlantic region. The combination of an approaching surface cool front, higher heat and humidity, a strong low-level jet, wind shear, and an upper-level trough will result in showers and thunderstorms from later today into tonight and any thunderstorm can reach severe levels. The severe weather threats include damaging wind gusts, heavy rainfall, and large hail. In addition, given the expected formation of strong wind shear, there will also be the potential of isolated tornadoes.

An approaching cool front and a decaying complex of thunderstorms may be just enough to trigger the development of afternoon and evening showers and thunderstorms across the Tennessee Valley. This threat of rain will diminish late tonight and Thursday promises to be a nice break from the heat and humidity as high pressure arrives from the middle of the nation.

Several ingredients will come together late 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 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.

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.

Several ingredients will come together late tomorrow and tomorrow night to produce the chance of strong-to-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 an upper-level trough will likely result in showers and thunderstorms from later tomorrow into tomorrow night and any storm can reach strong-to-severe levels. The main threat should be damaging wind gusts; however, given the expected strong wind shear, there will also be the potential of isolated tornadoes; especially, over northeast PA and NW NJ.

A cool front passed through the Mid-Atlantic region early Monday and ushered in a comfortable air mass featuring noticeably lower humidity levels than recent days and they’ll stay in the moderate zone today. It’ll turn hotter and more humid on Wednesday ahead of the next cool frontal system and that front is likely to produce afternoon and evening showers and thunderstorms in the Mid-Atlantic region. Some of the PM thunderstorms on Wednesday can reach strong-to-severe levels. More comfortable air returns to the region on Thursday following the passage of the mid-week front and it stays comfortable into the weekend. Another front is likely to bring another round of showers and thunderstorms to the Mid-Atlantic region on Saturday night and Sunday.
