Philadelphia, PA – A low pressure system moving into Pennsylvania from the southwest is expected to bring widespread rain and isolated thunderstorms through Thursday night, with rainfall totals reaching up to 1.5 inches in parts of the state.
According to the National Weather Service in Mount Holly, the unsettled pattern began Monday night and is forecast to persist until Thursday evening. The heaviest rainfall is anticipated across southeastern Pennsylvania, including Philadelphia, Allentown, and Reading, where between 1 and 1.5 inches of precipitation could accumulate. Localized thunderstorms may result in even higher totals.
Wilmington, DE, and Trenton, NJ, are also expected to receive similar amounts of rain as the system spreads across the Mid-Atlantic region. The NWS warns of potential ponding on roads, especially during the evening commute Tuesday and Wednesday, and urges caution when driving through low-lying areas.
The rain should taper off by Thursday night, offering a brief reprieve before additional unsettled weather may return Friday morning. Residents should monitor local forecasts, secure outdoor items, and ensure gutters are clear to prevent minor flooding.
This weather pattern follows a relatively dry spring period for much of the region, making storm drainage efficiency especially important in urban areas like Philadelphia.
