Philadelphia Weather: Sunny Start to the Week Before Late-Week Storms and Temperature Swings

Philadelphia, PA – Residents in the Philadelphia region are enjoying a picture-perfect start to the week with sunshine, low humidity, and temperatures hovering in the upper 80s, though conditions are expected to shift with the arrival of clouds and possible storms later this week.

Sunny Monday Brings Ideal Summer Conditions

Monday kicks off with mostly sunny skies and comfortable humidity levels, making for a fantastic start to the week. Highs are expected to reach 88°F, with some parts of the area potentially touching 90°F.

However, haze from distant wildfires may be visible across the region. The smoke will be most noticeable in Delaware today and could spread closer to Philadelphia by Tuesday and Wednesday.

Warming Trend Through Midweek

Tuesday continues the warm, dry trend with highs around 88°F, under partly cloudy skies and a touch more humidity. Clouds will begin building Tuesday night as moisture arrives on an onshore flow, signaling a change in weather patterns.

By Wednesday, increasing cloud cover from a southern system will spread north, although high pressure overhead should keep the area mostly dry. Temperatures will drop slightly, with highs in the low 80s.

Slight Rain Chances From Thursday On

A stray shower is possible beginning Thursday, especially in areas south and east of the city, as a low-pressure system offshore begins to influence local weather. While the system’s track remains uncertain, forecasters are keeping low rain chances in the forecast from Thursday through Saturday.

Expect highs in the upper 70s to low 80s Thursday, followed by a rebound into the upper 80s by the weekend.

“We’re watching a potential low-pressure system offshore. It could bring more rain late in the week depending on its track,” meteorologists noted.
