They actually mention tornados.

Scattered showers and thunderstorms are possible Monday evening as a storm system moves over southern Pennsylvania. First a warm front lifts from south to north allowing for incredibly high levels of moisture to pool ahead of developing showers and thunderstorms to our southwest as we head past sunset.
As the front lifts to our north these scattered showers and thunderstorms may increase in strength and number closer to sunset and into the early overnight hours. The biggest concerns are storms that produce strong damaging wind gusts greater than 60 miles per hour. There may storms that produce very heavy rainfall leading to localized flash flooding. Because of the advancing warm front and western motion of the thunderstorms that could create enough "spin" in the atmosphere to get these storms to rotate and a brief, spin-up tornado could form.
