Philadelphia is in for a hot, mostly sunny Sunday with a high near 93°F, and while forecasters can’t completely rule out an isolated shower or thunderstorm after 2 PM, most of the day should stay dry — so get your outdoor plans in before the afternoon sky gets moody.
Today’s Setup
A weak cold front slid through the Philadelphia region early this morning, and the National Weather Service’s Mount Holly office says that’s ushering in slightly drier air aloft, which should keep a lid on widespread storms today. Forecasters aren’t ruling out an isolated pop-up storm this afternoon, especially where the sea and bay breeze off the Jersey Shore collides with westerly winds inland — any that fire could bring a brief strong gust and frequent lightning before fading by sunset. Winds stay light at 5 to 10 mph out of the west, with tonight’s low settling near 74°F under mostly clear skies.
Best Window To Be Outside
Morning through early afternoon is your window, whether you’re on the Schuylkill River Trail, the golf course, or headed to Citizens Bank Park, where the Philadelphia Phillies host the Toronto Blue Jays today for Toyota Phillies Alumni Day. Fans at Subaru Park for Philadelphia Union vs. Club Necaxa should watch the western sky late in the match, since the isolated storm risk climbs after 2 PM. Get tickets on SeatGeek or Find tickets on StubHub if you’re still deciding, and pick up Official team gear on Fanatics before kickoff.
Rain, Wind, Fire, Or Heat Risk
No severe weather outlook covers Philadelphia today, and the Weather Prediction Center’s excessive rainfall concerns are focused on the Upper Midwest, not the Delaware Valley. The bigger story is heat and humidity: the NWS says hot, sticky conditions persist into midweek, though not quite as oppressive as recent days. Daily storm chances return Monday, with a 50% chance after 2 PM and a broader risk of strong to severe storms and localized flash flooding as the week goes on.
What To Wear Or Bring
Light layers and sun protection win today — a golf polo shirt men’s cut works for the course or errands, and anglers should pack a waterproof fishing tackle bag before hitting the river. Chasing that fishing-season sun? Don’t miss the UPF 50+ Sun Hoodie deal for just $5. As it turns muggy this evening, keep mosquito repellent spray handy on the porch or trail. Browse more outdoor gear deals while you’re at it.
Tonight’s Dinner
With a dry, 93°F afternoon on tap, it’s a great night to fire up the grill for burgers, steaks, or grilled chicken with corn on the cob. Keep an instant-read meat thermometer and grill brush and scraper set on hand, and for something different, try our guide to smoking tri-tip like brisket. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Monday turns hotter with a high near 94°F and a 50% chance of afternoon storms. The humid, unsettled pattern continues into midweek with a risk of stronger storms and heavy rain. Looking ahead, Foo Fighters bring the TAKE COVER TOUR to Lincoln Financial Field on August 13 — grab tickets on SeatGeek and gear up with a Foo Fighters t-shirt or Foo Fighters hoodie before the show.
