Philadelphia is heading into a Saturday that should turn partly sunny, with temperatures climbing toward 72 degrees. The calmer weather will not last all weekend: showers are expected Sunday, followed by a noticeably cooler start to next week.

At Philadelphia International Airport, the National Weather Service reported 70 degrees, mostly cloudy skies and northeast winds at 10 mph with gusts to 20 mph at 12:54 p.m. Saturday. That is a midday observation; the city forecast calls for partly sunny skies and a high near 72, with east winds around 5 mph. The airport’s latest conditions and Philadelphia forecast show both readings.

Saturday Offers A Mild Outdoor Window

Saturday, October 3, should turn partly sunny by afternoon, with light northeast winds around 5 mph and only a minimal chance of rain. The forecast looks favorable for errands, neighborhood walks and outdoor plans.

The National Weather Service’s Mount Holly office says high pressure will build over the region, helping skies clear for much of the Philadelphia area. No watches, warnings or advisories are listed for the city.

Sunday Showers Arrive After 9 A.M.

Sunday brings the weekend’s main weather complication, with showers expected mainly after 2 p.m. and an 80% chance of precipitation in the Philadelphia forecast. Mostly cloudy skies and easterly winds will hold the high near 66 degrees, the National Weather Service’s latest forecast says.

The Sunday forecast calls for between a tenth and a quarter inch of new precipitation, with an 80% chance of rain during the day and a 20% chance Sunday night. Showers are expected mainly after 2 p.m., and the forecast allows for a slight chance before 2 a.m. Monday. The National Weather Service’s Philadelphia forecast points to a wet interruption, but not a forecast of steady rain all night.

The timing and rain chances represent a more unsettled outlook than the earlier weekend forecast, according to Hoodline’s previous update. Temperatures fall to around 59 degrees Sunday evening, the current Philadelphia forecast shows.

Clear Skies Return With A Cooler Feel

Monday should bring mostly sunny skies and a high near 71. Tuesday will be sunny but only reach around 63 degrees.

The current Philadelphia forecast calls for clear skies Tuesday night, with a low near 46 degrees. Wednesday should be sunny, with a high near 67, and Thursday sunny, with a high near 71, according to the National Weather Service.
