Pittsburgh, Pennsylvania – Summer scorches into western Pennsylvania as temperatures climb into the 90s through Sunday, with the hottest day expected in Pittsburgh on July 7. Saturday and Sunday will be dangerously hot, prompting a summer weather alert for residents heading outdoors or traveling along major routes like Route 28 and I-376.
According to the National Weather Service, Thursday will reach a high near 88°F after early morning fog. Friday and Independence Day bring near-identical highs of 87°F under sunny skies — ideal for fireworks and barbecues. However, calm winds and clear skies will give way to rising humidity and peak heat heading into the weekend.
Expect highs near 91°F Saturday and 94°F by Sunday, with partly cloudy skies offering little relief. Nights will remain warm and humid, with lows only dropping into the upper 60s and low 70s. Residents should stay hydrated, limit strenuous outdoor activities, and check on vulnerable neighbors.
Relief may come Monday afternoon, but not without a risk: showers and thunderstorms are likely after 2 p.m., with a 50% chance of precipitation. Another round is possible Tuesday night and Wednesday.
Keep your devices charged and stay alert to sudden changes in weather conditions.
