PITTSBURGH, Pa. – A summerlike stretch continues across western Pennsylvania this weekend, with sunshine and rising heat creating a September warm-up. Temperatures in Pittsburgh are climbing into the mid-80s by Sunday, keeping roads dry but raising air quality concerns for sensitive groups. Commuters along I-376 and the Parkway West should prepare for patchy morning fog before skies quickly clear.
According to the National Weather Service in Moon Township, Sunday will stay sunny with highs near 86 degrees and calm winds. Nights bring some relief, with lows around 60, though humidity may keep evenings feeling warmer. Drivers should remain alert for reduced visibility during the overnight and early morning hours, especially in low-lying valleys and river crossings.
The warming trend builds into Monday, when highs reach 87. Afternoon winds may pick up slightly but won’t offer much cooling. Tuesday and Wednesday continue with mostly sunny skies, highs between 84 and 86, and comfortable evenings in the low 60s. These stable conditions should ease travel across Allegheny, Beaver, and Washington counties, though residents should monitor hydration and limit strenuous outdoor activity during peak afternoon heat.
With no rain in the forecast, outdoor plans remain safe through midweek, making it ideal for sports, festivals, or late-summer yard work. The warm stretch also reduces short-term flood risk, though officials encourage residents to conserve water as dry conditions persist.
Warm, sunny days dominate the upcoming workweek, but cooler nights signal the first hints of fall’s arrival. Additional updates are expected if weather patterns shift later in the week.
