PHILADELPHIA, Pa. –
A soggy Sunday is on the way for much of southeastern Pennsylvania as a strong fall storm system sweeps in from the coast, bringing widespread rain, gusty winds, and a noticeable cooldown by early next week. The system is expected to create slick travel conditions and reduced visibility along I-95, I-76, and major urban arteries through Sunday night.
According to the National Weather Service in Mount Holly, rain chances rise sharply after daybreak Saturday, peaking Sunday as steady rainfall combines with winds gusting 20 to 25 mph. By late Sunday, temperatures will tumble into the 50s, ushering in a crisp, breezy pattern that continues into Monday. Commuters should plan extra time for slower highway travel and be alert for ponding in low-lying areas.
Rainfall totals may approach an inch in some areas, raising the risk of localized flooding, especially near creeks and storm drains. Outdoor events, pumpkin patch visits, and fall festivals could see washouts this weekend, though brighter, milder weather should return by midweek. Residents are advised to check drainage around homes and secure lightweight decorations ahead of the winds.
By Tuesday, high pressure builds back in with sunshine and a classic fall chill. Morning lows will dip into the mid-40s, signaling the season’s first brush with a potential cold snap later next week.
