Pittsburgh, Pennsylvania – Rising summer heat and a renewed threat of severe storms will converge on Pittsburgh Monday, setting up a week of unsettled weather for Allegheny County and beyond. Travel on major roadways like I-376 and Route 28 could be impacted by periods of heavy rain, localized flooding, and damaging wind gusts.
According to the National Weather Service in Pittsburgh, scattered thunderstorms will develop after 11 a.m. Monday, July 14, bringing the risk of flash flooding, especially near the Appalachian ridge-line and lower-lying neighborhoods. Motorists should remain alert for ponding water, especially along I-376, I-79, and local streets prone to quick runoff. Commuters are advised to slow down and avoid water-covered roads.
The threat of storms continues into Monday night, with patchy fog possible as rain lingers. Additional showers and thunderstorms will return Tuesday afternoon, with the mercury soaring to a humid 91°F. The risk of localized flooding and strong winds increases on Wednesday as another round of summer storms targets Pittsburgh and surrounding areas, including Butler and Westmoreland counties.
Residents are urged to prepare for brief power outages and keep electronic devices charged. If you live in a flood-prone area, review your evacuation plans and clear storm drains before storms hit. Be cautious around swollen creeks and avoid walking or driving through floodwaters.
By late week, conditions remain unsettled. Storms are likely Thursday, with a chance of lingering showers on Friday. The first clear, dry day is expected Saturday, providing a brief break before storm chances return.
Warnings remain in effect for the Pittsburgh region through Wednesday night, with additional alerts possible as summer storms persist.
