After a calm and seasonably warm Saturday, Pittsburgh and much of western Pennsylvania are preparing for a more unsettled stretch of weather beginning Sunday. The National Weather Service in Pittsburgh warns that a series of disturbances will trigger rounds of showers and thunderstorms across the region, with activity likely to linger into midweek. While Saturday brings mostly sunny skies and highs in the low 80s, the pleasant conditions will soon give way to a stormier pattern that may complicate travel and outdoor plans.
By Sunday afternoon, rain chances rise sharply to between 45 and 55 percent across western Pennsylvania and northern West Virginia. Cities such as Pittsburgh, Butler, and Morgantown are expected to experience scattered thunderstorms capable of producing periods of heavy rainfall, lightning, and gusty winds. The National Weather Service notes that while not all areas will see storms at once, any community that does could face a quick burst of intense conditions. With temperatures in the low 80s and rising humidity, the atmosphere will be primed for active weather.
The unsettled conditions are not expected to pass quickly. On Monday, isolated showers will linger, with a modest 20 percent rain chance and highs near 82 degrees. However, by Tuesday, storm coverage increases again, with Pittsburgh carrying about a 50 percent rain chance and nearby communities such as Morgantown and Dubois seeing probabilities as high as 60 percent. These storms could be more widespread and may repeat over the same areas, raising concerns for localized flooding. By Wednesday, the storm threat remains elevated, with rain chances near 55 percent and highs staying in the low 80s.
Travelers and commuters should remain alert, particularly along major routes such as I-79, I-376, and the Pennsylvania Turnpike. Heavy downpours may cause reduced visibility and ponding on roadways, leading to slower travel times. Gusty winds and lightning could also briefly disrupt outdoor events and activities. Forecasters encourage residents to secure outdoor furniture, keep electronic devices charged in case of power outages, and monitor forecasts for updates as conditions evolve.
The extended outlook underscores a prolonged period of instability. While Saturday provides a welcome break with dry skies and comfortable warmth, the return of rain and thunderstorms beginning Sunday will dominate the region’s weather through at least midweek. Each day carries its own hazards—from localized flooding potential to brief gusty winds and travel delays—making preparedness and flexibility important.
Western Pennsylvania and northern West Virginia are heading into a stormier stretch of weather after a quiet start to the weekend. From scattered thunderstorms on Sunday to more widespread activity Tuesday and Wednesday, the pattern suggests multiple rounds of unsettled weather. While temperatures will remain near seasonal norms in the low 80s, it is the frequency and intensity of storms that will shape the week ahead. Residents should stay weather-aware, particularly during afternoon and evening hours, when storms are most likely to develop.
