Pittsburgh, PA – Drivers across northwest Pennsylvania are experiencing reduced visibility along Interstate 80 today as light snow continues to move through Mercer, Venango, Clarion, and Jefferson counties.
According to the National Weather Service Pittsburgh office, most visibility reports along I-80 this afternoon have ranged between 4 and 6 miles. However, forecasters noted that occasional drops to around 1 mile are possible as snow bands shift across the corridor. The agency emphasized that while accumulation will remain light, travel impacts are still likely, especially on bridges, ramps, and untreated surfaces.
The update included a traffic camera view from mile marker 35 near Clintonville, where light snow was visible on grassy areas and along the sides of the roadway. While pavement appeared mostly wet, forecasters warned that temperatures could allow isolated slick spots through the evening hours.
Snow coverage on radar extended across much of northwest Pennsylvania, with patchy bursts producing variable driving conditions. Forecast models show the steadier snow pushing east later tonight, though on-and-off flurries may linger into early Wednesday.
Officials are advising motorists to allow extra travel time, maintain safe following distances, and be prepared for quick changes in visibility, especially when passing through heavier bursts. No widespread road closures were reported as of this afternoon.
Residents across Mercer, Venango, Clarion, and Jefferson counties can expect light snow to taper by late evening, with improving travel conditions overnight.
