Pennsylvania – Damp streets and shifting clouds across the Philadelphia region signal a fast-changing stretch of March weather. The morning begins calm with temperatures climbing toward 56°F, but a stronger storm pattern will quickly take control across the Mid-Atlantic.
According to the National Weather Service, scattered rain and a possible thunderstorm begin developing later today, with steadier rain arriving toward the early morning hours. Rainfall totals could reach 0.25 to 0.50 inches, and patchy fog may briefly reduce visibility across parts of the I-95, I-76, and Schuylkill Expressway corridors.
The atmosphere becomes more active Monday. Temperatures jump toward 67°F in Philadelphia, creating a springlike feel before a volatile storm line approaches. Meteorologists say severe thunderstorms are possible by late morning and afternoon, producing wind gusts near 35 mph and bursts of heavy rain.
Drivers across southeastern Pennsylvania and nearby New Jersey should prepare for rapidly changing conditions. Wet pavement and gusty winds could slow travel on Interstate 95, the Ben Franklin Bridge, and Route 1 during peak travel hours.
Colder air quickly follows the storm system. Showers continue Monday night while temperatures drop toward 32°F, with gusty winds reaching 40 mph. Any lingering moisture could freeze on elevated roadways by early Tuesday.
St. Patrick’s Day Tuesday turns noticeably cooler but calmer. Temperatures struggle near 40°F, and a few lingering showers early may give way to brighter skies later in the day.
Sunshine returns midweek with highs in the low 40s Wednesday before moderating again toward the low 50s Thursday. Longer-range outlooks hint at a broader warm spell developing late next week, a sign that spring may soon gain momentum across Pennsylvania.
