Pittsburgh, Pa. – Drivers in western Pennsylvania may face wet roads and possible delays Sunday as thunderstorms develop across the Pittsburgh region. Motorists on I-376 and I-79 should prepare for sudden downpours that could reduce visibility and slow travel during peak afternoon hours.
According to the National Weather Service in Pittsburgh, storms are expected between 11 a.m. and 2 p.m. Sunday before tapering to showers by evening. Rainfall totals may reach a half inch in some areas, with localized flooding possible in low-lying neighborhoods and along smaller roads. Gusts could approach 25 mph during stronger storms.
The unsettled pattern will ease by Monday, when skies turn partly cloudy and highs drop into the mid-70s. Cooler, drier air will dominate through midweek, creating safer conditions for commuters and outdoor events.
Travelers heading to Pittsburgh International Airport Sunday should allow extra time, as passing thunderstorms may cause minor flight delays. PennDOT crews remind drivers to slow down when roads slick over, especially on bridges and ramps where water can collect quickly.
Residents planning outdoor activities Sunday should keep phones charged for alerts and be ready to move indoors when storms approach. Conditions improve rapidly overnight, setting the stage for a stretch of mild, sunny weather.
Warnings remain in place through late Sunday evening, but no additional watches are posted as of Saturday night.
