Pittsburgh, Pa. – Southwestern Pennsylvania will see another hot, dry day Monday, with highs pushing near 90 degrees under mostly sunny skies. Light winds and low humidity will make for a calmer start to the workweek, but that pattern changes quickly by Tuesday.
According to the National Weather Service in Pittsburgh, a slight 20–30% chance of isolated thunderstorms develops Tuesday afternoon and evening, with most areas staying dry. The greater concern comes overnight Tuesday into Wednesday, when storm coverage is expected to expand and bring more widespread showers across the region.
Storms on Wednesday could be accompanied by gusty winds and brief downpours, particularly during the afternoon commute. Highs will cool into the mid-80s under mostly cloudy skies, offering some relief from Monday and Tuesday’s heat. Motorists should be prepared for reduced visibility in heavy rain and potential ponding on roadways, especially in low-lying areas.
The unsettled pattern may persist into late week, with additional shower chances possible. Residents should monitor updates as timing and intensity of storms become clearer.
