Philadelphia is in for a stormy Wednesday with a high near 85°F and a 60% chance of showers and thunderstorms developing this afternoon — grab a compact travel umbrella before you head out and keep outdoor plans to the morning hours.
Today’s Setup
A warm front lifting north of the area today will send dewpoints surging toward 70°F by midday, according to the National Weather Service, making it feel oppressively humid long before any rain arrives. Cloud cover will hold our high near 85°F along the Delaware Valley, but that sticky air makes it feel worse than the number suggests. Schuylkill River Trail runners and anyone planning time at Rittenhouse Square or FDR Park should get moving early.
Best Window To Be Outside
Get outside before noon. The National Weather Service expects isolated showers between 7 AM and noon ET, with more organized showers and thunderstorms developing from noon through 5 PM ET and continuing into the early evening. A packable rain jacket stuffed in your bag will be worth its weight this afternoon.
Storm Risk: What To Know
The National Weather Service flags a Marginal Risk of severe thunderstorms this afternoon. The main threats are heavy downpours and frequent lightning — instability is modest, around 1,000–1,500 J/kg, so storms should stay disorganized and short-lived. Still, if you’re heading out to see Josh Groban with special guest Jennifer Hudson or catching Ryan Bingham and The Texas Gentlemen at The Fillmore Philadelphia tonight, check the radar before you leave. Storms should wrap up by 11 PM ET.
Heat Wave Alert: Thursday and Friday
Thursday is where things turn dangerous. The National Weather Service has issued a Heat Advisory with a high near 95°F and heat index values as high as 102°F — real feels-like summer danger for South Philly, Fishtown, and anyone working outdoors. Stay hydrated; a hydration backpack is a smart call if you’re spending extended time outside. A 40% chance of afternoon thunderstorms remains Thursday too. The weekend is trending drier and more comfortable.
World Cup Weekend at Lincoln Financial Field
Start planning now: World Cup Match 9 Group E — Ivory Coast vs. Ecuador kicks off Sunday, June 14 at Lincoln Financial Field. If you still need seats, Find tickets on StubHub or Get tickets on SeatGeek before they’re gone. Pick up some Official team gear on Fanatics ahead of game day.
What To Bring Today
- compact travel umbrella — don’t leave home without one
- packable rain jacket — essential for afternoon and evening plans
- waterproof hiking boots — if you’re hitting trails before noon
Rainy Night Dinner Idea
Tonight is a perfect slow cooker night. Toss everything in a programmable slow cooker this morning — chili, beef stew, or chicken soup — and it’ll be ready when the storms roll through. An enameled cast iron Dutch oven works great for a batch of French onion soup on the stovetop. Need ingredients? You can order groceries on Amazon and have everything delivered before the afternoon storms arrive.
Next Few Days
- Thursday: High near 95°F, heat index up to 102°F, Heat Advisory in effect, storms possible after 2 PM ET
- Friday: Continued dangerous heat and humidity, thunderstorm chances persist
- Weekend: Trending drier — better conditions returning ahead of the World Cup at Lincoln Financial Field
