Philadelphia wakes up to patchy fog before 8 AM, then clears into a mostly sunny, comfortable day with a high near 84°F—easily the pick of the week, so get outside while you can.
Today’s Setup
Weak high pressure is building in, and per the National Weather Service, winds stay light out of the east around 5 mph. It’ll be a bit cooler right along the coast and up on the Pocono Plateau, where highs only reach the upper 70s. Humidity is present but not oppressive—the heat index should run just a few degrees above the actual temperature, a welcome break from recent stickier days. Tonight cools to near 69°F under partly cloudy skies with only a 3% chance of rain.
Best Window To Be Outside
Midday through late afternoon today is the sweet spot—clear, dry, and light winds along the Schuylkill River Trail, in Fairmount Park, or anywhere around Center City. If you’re squeezing in nine holes, this is the day: golf weather doesn’t get much better than today’s mix of sun and calm wind. A set of Pinemeadow Golf hybrids or a golf GPS watch could be handy if you’re heading to the course before conditions turn.
Storms Arrive Thursday
Enjoy today, because the forecast discussion flags a real pattern change. Isolated showers develop Wednesday night into Thursday morning, then coverage increases Thursday afternoon and evening as a piece of upper-level energy and a cold front move through. Southwest winds will pump in deep moisture—PWAT values near 2 inches—so showers and thunderstorms (65% chance Thursday, high near 85°F) could produce heavy downpours with a quarter to half inch of rain, and another half to three-quarters of an inch Thursday night. Rounds of storms look likely into Friday as the front crosses the region, with lingering activity possible Saturday before drier air returns Sunday.
What To Wear Or Bring
Light layers and sunscreen today; keep the umbrella handy starting Thursday afternoon. If you’re planning an evening on the patio tonight, a citronella candle set will help keep bugs away while the air stays calm and dry.
Concerts And Tailgating This Week
Indoor plans are the smart bet once storms arrive. Poppy brings her Constantly Nowhere Tour to The Fillmore Philadelphia this Thursday, July 9—good timing to be under a roof as afternoon storms roll through. Saturday, July 11, Megan Moroney’s Cloud 9 Tour lands at Xfinity Mobile Arena—check out our in-depth Megan Moroney tour coverage for more, and grab a Megan Moroney t-shirt to wear to the show. That same night, Louis Tomlinson’s How Did We Get Here? World Tour plays the outdoor Skyline Stage at Highmark Mann—see our Louis Tomlinson tour details before you go, since it’s worth watching the forecast update for lingering weekend showers. For any of these, tickets on SeatGeek or tickets on StubHub are worth checking before prices climb.
With possible power blips from Thursday’s storms, it’s not a bad week to grab the DARAN 288Wh Power Station deal for backup power at home.
Tonight’s Meal Idea
With calm, dry air and a warm evening, tonight is perfect grilling weather—fire up the grill for burgers, steaks, or grilled chicken with corn on the cob. An instant-read meat thermometer and a grill brush and scraper set make cleanup and doneness a lot less guesswork. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
After today’s sunshine, expect rounds of showers and thunderstorms Thursday into Friday as the cold front crosses Philadelphia, with a few lingering storms possible Saturday before drier conditions settle in by Sunday.
