Pittsburgh, Pennsylvania – A stormy Friday afternoon could bring traffic slowdowns across Allegheny County and surrounding areas, with heavy downpours and possible thunderstorms arriving just in time for the evening commute.
According to the National Weather Service in Pittsburgh, showers will develop Friday morning, becoming widespread and possibly severe between 2 p.m. and 8 p.m. A slight risk for excessive rainfall exists across western Pennsylvania, with locally higher amounts expected—up to one inch in some areas.

Friday night will remain wet, with more showers and thunderstorms expected before midnight. While no severe weather warnings are currently in effect, drivers are urged to reduce speed and watch for ponding water and reduced visibility during evening hours.
