Pittsburgh, PA – Western Pennsylvania wakes to steady rain this Tuesday, October 7, as a fast-moving cold front brings the region’s first real taste of fall. Commuters across Allegheny, Beaver, and Butler counties should prepare for slick roads and brief downpours through the morning commute.
According to the National Weather Service in Pittsburgh, multiple rounds of rain could lead to localized flooding today before conditions clear by late Wednesday. Drivers on I-79 and I-376 may encounter reduced visibility and ponding water during the heaviest rain bands.
