Pittsburgh, Pennsylvania – After a weekend marked by warm, sticky air across western Pennsylvania, residents can expect a short-lived break from the heat as temperatures fall into the low to mid-80s Monday. Communities from Pittsburgh to Butler and New Castle are set to see high temperatures in the 82°F to 84°F range—just below Sunday’s widespread upper-80s.
According to the National Weather Service in Pittsburgh, this reprieve will be brief. By Tuesday, a surge of warm and humid air is expected to push high temperatures back to the upper-80s and near 90°F across Allegheny, Beaver, and Westmoreland counties. Morning commuters in areas such as Washington and Indiana should still prepare for muggy conditions, though Monday’s lower temperatures may offer some relief for outdoor workers and school activities.
Residents are advised to keep hydrated, limit strenuous activity during peak heat hours, and check on vulnerable neighbors, especially as heat indices rise again midweek. Those traveling on I-79 or Route 22 should expect dense afternoon traffic and possible delays as roadways heat up. It’s the kind of July swing typical for the region, with humidity levels adding to discomfort.
This cooler trend lasts just one day, with higher temperatures and more advisories possible as the week progresses.
