PENNSYLVANIA – Drivers heading into the weekend should prepare for slick roads and reduced visibility as showers and fog move across western Pennsylvania. The unsettled pattern could bring delays on I-376 and other major routes through Pittsburgh starting Saturday morning. Residents are urged to allow extra travel time and avoid unnecessary driving when fog thickens.
According to the National Weather Service, scattered showers and possible sprinkles will develop Saturday with patchy fog returning Saturday night into Sunday morning. Visibility may drop quickly during early commutes, especially along river valleys and low-lying roads. Rainfall amounts should stay light, but wet pavement paired with fog raises safety concerns.
Pittsburgh will see highs near 78 degrees Saturday and 79 Sunday before temperatures dip slightly at night. Calm winds and moisture pooling near the surface make conditions favorable for persistent fog into Monday morning. By midweek, drier air arrives with cooler mornings signaling the approach of October’s early fall chill.
Travelers should plan for reduced speeds and keep headlights on in fog. PennDOT reminds drivers to avoid cruise control on slick surfaces and give extra space between vehicles. Outdoor events Saturday may need quick adjustments as showers pass through.
The unsettled pattern eases by Tuesday, with drier conditions leading into the first days of October. Cooler nights in the lower 50s will mark the season’s shift, though no freezing temperatures are expected yet. More fall-like weather could develop by mid-October.
