Pittsburgh, Pennsylvania – Severe spring weather will bear down on western Pennsylvania starting Tuesday afternoon, with thunderstorms and damaging winds threatening to disrupt travel and power across Pittsburgh by Tuesday night. Key interstates like I-376 and I-79 are expected to see the brunt of the impact, especially during the evening commute and overnight hours.
According to the National Weather Service in Pittsburgh, thunderstorms are likely to develop after 2 p.m. Tuesday, intensifying into the night. The agency warns of possible severe wind gusts, heavy rainfall, and sudden visibility drops on major roadways. Power outages and downed trees may occur, especially in areas hit by the strongest cells. Residents are urged to charge devices now and secure any loose outdoor items ahead of Tuesday afternoon.
Drivers on I-376, I-79, and I-279 should prepare for hazardous conditions after sunset, with hydroplaning and fallen debris possible. Non-essential travel is discouraged during active storm periods. If you must be on the road, slow down, use headlights, and avoid flooded areas.
Showers linger into Wednesday morning, but skies will turn partly sunny by afternoon with a high near 74°F. The reprieve is brief—another round of rain and possible storms moves in Wednesday night into Thursday, keeping the region unsettled. Showers are likely through Thursday and Friday, before sunshine returns Saturday.
Stay alert for updated warnings and additional weather advisories as Tuesday’s threat develops. Warnings remain in effect for Tuesday afternoon through Tuesday night.
