Southeastern Pennsylvania is enjoying a peaceful stretch of early fall weather, and Philadelphia will continue to see mostly sunny skies and mild conditions through the start of the week.
While the days remain warm and pleasant, cooler nights and increasing cloud cover may lead to reduced visibility for late-night drivers, especially on I-95 and nearby roadways.
Sunny Sunday with Mild Temps and Cool Night
According to the National Weather Service, Philadelphia will experience a high near 84°F on Sunday, with light northwest winds around 5 mph. Skies will stay mostly sunny during the day, making it perfect for outdoor plans like walks, picnics, or sports.
However, as the sun sets:
Clouds return overnight
Lows dip to around 63°F
Damp conditions may develop on roads
Visibility may be limited for late-night drivers
If you’re planning to drive late Sunday night, especially on I-95 or through suburban areas, use extra caution, as damp roads and cloudy skies could affect visibility.
Mild Start to the Week with Slight Midweek Changes
The pleasant pattern continues into Monday, with mostly sunny skies and a high near 83°F. The night will be partly cloudy and cooler, with lows around 61°F.
On Tuesday, the weather shifts slightly:
Highs reach around 81°F
Skies turn mostly cloudy
Overnight clouds increase
This sets the stage for a potential weather change midweek.
Rain Chances Return Late Wednesday into Thursday
By Wednesday, skies become partly sunny, and daytime temperatures cool slightly to around 77°F. The first chance of rain arrives late Wednesday night, with a 30% chance of showers. While it’s not a major storm system, commuters should be aware that roads may become slick by Thursday morning, especially during rush hour.
