Pittsburgh is starting Tuesday, August 4, 2026, under clear skies with temperatures around 61°F in the latest local observation, but a brief patch of fog could linger before 9 a.m. The fog should give way to a sunny, hot afternoon, with temperatures climbing to near 87°F and only a light east breeze.
Sunny Tuesday, Quiet Tuesday Night
Once the fog lifts, dry conditions and sunshine are expected through the afternoon, with east winds staying light at 1 to 5 mph. Tonight will turn partly cloudy, with temperatures dipping to around 68°F and a southeast wind near 5 mph.
Storm Chances Build Wednesday
Wednesday starts partly sunny, but an isolated shower could develop between 1 and 2 p.m., followed by scattered showers and thunderstorms into the evening. The chance of rain is about 30% during the day and 50% Wednesday night, with temperatures reaching near 88°F before falling to around 70°F.
Rainiest Stretch Arrives Thursday And Friday
Showers and thunderstorms become more likely Thursday, when Pittsburgh could see an 87°F high and a 70% chance of rain. Friday looks like the wettest day of the stretch, with mostly cloudy skies, a high near 86°F and an 80% chance of showers and thunderstorms, according to the National Weather Service in Pittsburgh.
Forecasters say the most active weather may arrive Friday into Saturday, when locally heavy rain or stronger storms are possible, although specific impacts remain uncertain. No watches, warnings or advisories are currently posted for Pennsylvania, Ohio or West Virginia in the local forecast area.
Weekend Weather Stays Unsettled
Saturday remains mostly cloudy with a high near 85°F and a 50% chance of showers and thunderstorms. Sunday offers a mostly sunny high near 88°F with only a slight storm chance, while Monday stays warm near 88°F but brings a 40% chance of afternoon showers and thunderstorms.
