Southeast PA Forecast
Scattered showers, then thunderstorms as low pressure moves through the region Thursday…
A frontal boundary brings scattered showers to eastern areas Thursday morning, with another round of scattered showers and thunderstorms in the afternoon and evening as low pressure moves through the region. Some stronger storms will be possible mainly in our far western and southwestern areas. After evening storms exit, partial clearing is expected later at night.
Thursday’s system on the lead of a trough will effectively lower temperatures and humidity to very comfortable levels both Friday and Saturday with mostly sunny skies expected both days. Mostly cloudy skies on Sunday ahead of the next frontal boundary, which could touch off late day scattered showers, which continues into Sunday evening. Remaining on the cooler side of average behind the front on Monday with mostly sunny skies expected. An area of low pressure may affect the region late Tuesday and Tuesday night with showers, then partly cloudy skies return on Wednesday.
