Scattered showers and strong thunderstorms are currently moving eastward from south central PA and will affect parts of the Philly metro area later this evening. The western suburbs (e.g., Chester County) and northern suburbs (e.g., Montgomery County) will be the first areas to feel the affects of this batch of showers and thunderstorms between about 9 and 10PM. The rest of the metro region can expect scattered showers and storms between 10PM and midnight. Some of the storms will produce brief heavy rain and strong, gusty winds. More showers and storms are possible tomorrow as much cooler air moves in from the Upper Midwest.
