Discussion

An active cold frontal system supported by vigorous upper-level energy will generate heavy showers and potential strong thunderstorms in the Philly metro region from later today into early Thursday. Heavy rain on the order of 1-3 inches has the potential to create some localized flooding problems and scattered strong thunderstorms are possible during this upcoming heavy rain event. The heaviest and steadiest rain will end early tomorrow, but residual showers are possible Thursday afternoon as the upper-level low associated with this dynamic system passes nearby. High pressure will bring improvement to the Mid-Atlantic region as we close out the work week and begin the weekend with the return of some sunshine, but it'll turn noticeably cooler for Sunday and Monday.
