Philadelphia, Pennsylvania – Drivers and residents across Southeastern Pennsylvania should prepare for a sweltering and smoky Tuesday as early June heat and lingering wildfire haze settle in. Temperatures in Philadelphia are expected to spike to near 90°F by June 3rd afternoon, with hazy skies possibly reducing visibility and triggering air quality concerns.
According to the National Weather Service, the high Tuesday will reach 82°F under sunny skies, but warmer air and calm winds will allow smoke from Canadian wildfires to linger over the region. By Wednesday and Thursday, highs of 87°F and 90°F, respectively, will bring the first true summer-like stretch of June weather. Light south winds Tuesday night will only offer modest relief, with overnight lows staying around 60°F.
Air quality alerts could be issued as conditions worsen. Sensitive groups—such as children, older adults, and those with respiratory issues—are advised to stay indoors during peak afternoon hours. PennDOT has also warned drivers along I-76 and I-95 to anticipate reduced visibility from smoke haze, particularly during Tuesday’s evening commute.
Wednesday and Thursday bring continued heat and clear skies. However, a change is expected Friday into the weekend, when a 40–50% chance of showers and thunderstorms arrives, cooling things slightly but potentially disrupting weekend plans.
