PHILADELPHIA, Pa. – Damp leaves, gray skies, and the steady patter of early rain will mark the next turn in Philadelphia’s fall pattern, as a soaking system moves in Thursday and lingers toward Halloween. Roads could glisten by sunrise with puddles deepening through midday, making travel slow and sidewalks slick heading into the holiday.
According to the National Weather Service in Mount Holly, widespread rain arrives early Thursday with a chance of embedded thunder. Winds from the northeast may gust up to 35 mph, especially near the Delaware River and I-95 corridor. Rainfall totals could reach one to two inches before tapering late Thursday night, leaving behind damp air and a brisk breeze by Friday morning.
Friday’s Trick-or-Treat period looks drier but cooler, with temperatures in the upper 50s and a lingering northwest breeze. Streets and lawns may remain soft from the prior day’s rain, so families should plan extra time and wear visible clothing for low-light hours. By Saturday, sunshine returns with a classic crisp feel — perfect for leaf cleanup or early fall decorating.
Travelers should monitor conditions on the Schuylkill Expressway and Route 1 during Thursday’s rain window, where visibility could briefly drop under heavy bursts. Creeks and storm drains may see minor flooding during peak rainfall, though major impacts appear unlikely.
The Delaware Valley enters November under clearer skies but a chillier breeze — a sure sign that winter isn’t far behind.
