Philadelphia is waking up to a crisp, dry Friday before temperatures climb into the mid-70s under mostly sunny skies. The calm stretch will hold through Saturday, giving the city two solid days for outdoor plans before a much wetter Sunday arrives. Early Friday temperatures are in the mid-50s, with west winds adding a noticeable breeze later in the day.

Friday And Saturday Stay Mild And Mostly Dry

Friday will reach about 74 degrees, with west-northwest winds of 5 to 10 knots in the morning and 10 to 15 knots in the afternoon, gusting up to 20 knots, while Friday night turns mostly cloudy with a low near 53. Saturday should remain dry and partly sunny with a high around 73, although a slight chance of showers develops after 2 a.m. Sunday’s wetter forecast is a sharper turn than an earlier Hoodline outlook suggested.

Sunday Brings Heavy Rain And Possible Thunderstorms

Rain is expected Sunday, with a high near 72 degrees and a 50% chance of precipitation. The region could receive 1 to 2 inches of rain, with some areas possibly exceeding 2 inches, according to the National Weather Service.

Sunday night remains unsettled, with showers and thunderstorms likely and a low around 62 degrees. The regional forecast discussion warns that periods of heavy rain could produce isolated flooding, while a few strong storms and minor tidal flooding are also possible Sunday into Monday.

Columbus Day Starts Damp Before The Pattern Improves

Showers may linger into early Monday, and Monday carries a 50% chance of showers. Columbus Day should be mostly cloudy, with a high around 70 degrees, followed by Monday night.

Conditions look quieter after the holiday, with mostly sunny skies and a high near 75 on Tuesday. Wednesday should be cooler and dry, with a high near 69 degrees, while Thursday could bring a chance of afternoon storms.
