Pennsylvania – Sunshine and dry pavement dominate Philadelphia this morning, but the quiet stretch begins changing within 36 hours. Temperatures climb to 82 degrees today before a warmer, wetter pattern develops through Wednesday.
According to the National Weather Service, Philadelphia International Airport reported 70 degrees with northeast winds near 8 mph this morning. Humidity stood at 53%. Visibility was 10 miles. Tonight’s low reaches 63, with patchy fog developing after 1 a.m.
Sunday brings the first notable change. Philadelphia reaches 87 degrees before showers and thunderstorms become possible after 5 p.m. The rain chance stands at 30%. That timing could affect evening traffic along I-95, I-76 and the Schuylkill Expressway.
Keep an umbrella nearby if Sunday plans stretch into the evening. Thunderstorms remain possible after 7 p.m., with temperatures holding near 71 degrees.
Monday stays warm at 87 degrees. A slight shower chance develops after 2 p.m. The wetter window arrives from 8 p.m. through 2 a.m., when rain chances rise to 40%. The NWS indicates rainfall could total one-tenth to one-quarter inch, with higher amounts possible in thunderstorms.
Tuesday turns hotter, reaching 88 degrees. Showers become possible after 2 p.m. with a 40% chance continuing into the evening. Drivers could encounter briefly wet pavement during the afternoon and evening commute.
Wednesday keeps the summer pattern locked in. Philadelphia again reaches 88 degrees, with a 30% chance of showers after 2 p.m. No snow, near-freezing temperatures or flash-freeze conditions appear in the supplied Philadelphia data.
The national setup supports the changing pattern. The Weather Prediction Center expects a stationary front to extend into the Mid-Atlantic by Monday. That boundary provides another focus for showers as the new week begins.
For now, Philadelphia gets a dry start before repeated afternoon and evening rain opportunities return. Additional alerts could follow if thunderstorm risks strengthen.
