Pittsburgh, Pennsylvania – Rain and thunderstorms will push into western Pennsylvania by late Thursday afternoon, with wet roads and reduced visibility likely developing before the evening commute.
According to the National Weather Service in Pittsburgh, dry conditions hold through Wednesday before a cold front triggers widespread rain and thunderstorms starting Thursday afternoon and intensifying into Thursday night. Storm coverage reaches as high as 85% to 90% across Pittsburgh, New Castle, and Wheeling by late evening, with locally heavy rainfall possible into early Friday.
Communities along the I-376, I-79, and Route 22 corridors should expect ponding water and slower travel speeds beginning around 6 p.m. Thursday. Areas including Morgantown, Latrobe, and Zanesville could see repeated rounds of rain overnight, increasing the risk for minor flooding in poor drainage zones. Rain chances remain elevated into Friday morning, with lingering showers potentially affecting the commute.
Temperatures will climb into the mid-60s Thursday before dropping into the low 40s by early Friday, creating a sharp cooldown behind the front. While severe weather is not the primary concern, isolated heavier downpours could quickly reduce visibility below a half mile at times.
Drivers should allow extra travel time Thursday night, avoid water-covered roads, and monitor local alerts for any flood advisories. Additional updates are expected as the storm system tracks through the region into Friday.
