PA Weather: Thunderstorms, Flooding Possible Wednesday

PENNSYLVANIA - Thunderstorms and showers are slated to hit the Keystone State throughout Wednesday, with flooding possible in parts of the state.

"A thunderstorm cannot be ruled out as these showers continue progressing eastward and out of the area this afternoon," the National Weather Service said. Clouds will begin to taper off later today, with lingering breezy conditions."

The northeast portion of the state is likely to see rain Wednesday with a 80 to 90 percent chance of precipitation, the weather service said. The southeast, including Philadelphia, stands at around a 80 percent chance of precipitation; the rest of the state has a 90 percent chance of rain.
