Philadelphia is starting Friday with muggy air, temperatures around 72 degrees and patchy fog hanging on through the morning. The fog should lift by 10 a.m., giving way to partly sunny skies and a high near 84. A few showers or thunderstorms could pop up from late morning through late afternoon, but this is not expected to be a washout.

Friday's Front Brings A Narrow Storm Window

A cold front will pass through the region Friday, bringing a 30% chance of showers and thunderstorms, according to the National Weather Service. The best chance for rain in Philadelphia runs from about 11 a.m. to 5 p.m., with partly sunny conditions returning around the storm window. Any rainfall should generally be light, with new totals expected to stay below a tenth of an inch.

The strongest storm risk is expected south and east of the city, particularly across southern New Jersey and the Delmarva Peninsula. No watches or warnings are listed for Pennsylvania, New Jersey, Delaware or Maryland in the current forecast package, but thunderstorms can still bring a quick downpour and lightning.

Saturday, August 29, Looks Like The Weekend's Easy Win

Saturday should bring a cleaner weather reset, with mostly sunny skies, a high near 84 and a low around 64 Saturday night. Winds will remain light from the north, generally 5 mph or less. Sunday, August 30, turns warmer at about 87 degrees, with mostly sunny skies and only a slight chance of showers Sunday night.

Summer Heat Rebuilds Into Tuesday

The warmth ramps up again Monday, August 31, when Philadelphia could reach 89 degrees under mostly sunny skies. Tuesday, September 1, may hit 90, with a 30% chance of showers and thunderstorms as humidity creeps back into the forecast. The broader outlook from the National Weather Service calls for a return to upper-80s and low-90s temperatures early next week.

Jersey Shore Beachgoers Should Watch The Water

Anyone heading to the Jersey Shore Friday or Saturday should note the moderate risk of dangerous rip currents, while Delaware beaches are listed at low risk. The regional forecast calls for no marine hazards, but swimmers should stay near lifeguards and avoid entering the water when conditions look rough.
