Philadelphia is waking to cloudy skies Tuesday as the departing nor’easter finally loosens its grip, with temperatures around the low 60s early and a high near 75. A stray sprinkle is possible, but meaningful rain should stay away, and the afternoon should turn partly sunny. Northwest winds are forecast to remain light.

Clouds Break As Philadelphia Warms Up

According to the National Weather Service, Tuesday night will be partly cloudy with a low near 59 before mostly sunny skies return Wednesday. Highs should reach 79 Wednesday, 82 Thursday and 84 Friday, making the middle of the week feel more like a last-minute summer encore than the start of October.

The warmer outlook is a modest but noticeable shift from Hoodline’s earlier forecast, which had Philadelphia topping out in the upper 70s through midweek. Friday remains mostly sunny during the day, with only a slight chance of showers after 8 p.m.

Weekend Rain Chances Rise Again

Saturday brings a 30% chance of rain showers and a cooler high near 74. The unsettled pattern becomes more likely Saturday night, when showers and possible thunderstorms could develop as temperatures fall to around 59.

Showers and thunderstorms are likely Sunday, with a 60% chance of precipitation and a high near 69 under mostly cloudy skies. The forecast then calls for a chance of early showers Monday before partly sunny conditions return, with a high near 67.

No Weather Advisory For Philadelphia

Philadelphia has no local weather advisories listed Tuesday. A Coastal Flood Advisory remains in effect until 2 p.m. Tuesday for vulnerable back-bay areas in New Jersey and Delaware, but the main city impact is a gradual shift from leftover clouds to warmer, drier weather.
