Severe storms could bring damaging winds to south-central Pa.

Storms could bring damaging winds, heavy rain and potentially tornadoes to parts of south-central Pennsylvania.A warm front first 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. Storm chances move east of the Valley between 2 and 4 a.m. as the storm moves into New England. Skies stay mostly cloudy with lows in the lower 70s.
