Pittsburgh, Pennsylvania – Tires hiss against wet pavement as temperatures dip below freezing across western Pennsylvania, creating a quiet but dangerous mix on roads just as post-holiday travel continues. A round of freezing rain is moving through the Pittsburgh region today, raising concerns about black ice on major highways and local roads.
The National Weather Service in Pittsburgh has issued a Winter Weather Advisory in effect through mid-afternoon, covering the metro area and nearby counties. Forecasters warn that even a light glaze of ice can quickly turn commutes hazardous, particularly during periods of steady precipitation.
Freezing Rain Creates Hazardous Travel Conditions
Temperatures across Allegheny County are hovering near 29°F as precipitation spreads in. Under these conditions, rain freezes on contact with cold surfaces, forming an invisible layer of ice. Bridges, overpasses, and elevated roadways are expected to ice first, increasing the risk of sudden loss of traction.
Travel along I-376, I-79, I-279, and Route 28 could become dangerous, especially during the morning and early afternoon hours. Untreated side streets, hills, and shaded areas are particularly vulnerable, where ice can linger even after conditions improve.
What Drivers Should Expect Today
Transportation officials urge drivers to adjust plans if possible and remain cautious if travel is necessary. Recommended precautions include slowing down, increasing following distance, and avoiding abrupt braking or steering. Conditions can deteriorate quickly once freezing rain begins, catching drivers off guard.
As the day progresses, temperatures are expected to rise above freezing, allowing rain to replace ice on many roadways. However, patches of black ice may persist in shaded or elevated areas, especially later in the afternoon.
Weekend Weather Brings Brief Relief
Saturday is expected to bring mostly cloudy skies with calmer conditions, offering a short window of improved travel for weekend plans. High temperatures should remain in the low 40s, reducing the immediate risk of icing.
Attention then turns to Sunday, when a warmer system moves in, bringing widespread rain and mild temperatures. While ice will not be the primary concern, periods of heavier rain could again impact travel conditions.
Looking Ahead to Early 2026
As New Year’s week begins, fluctuating temperatures will keep winter hazards in play. Forecasts suggest rain could transition to snow early next week as colder air returns. Repeated freeze-thaw cycles increase the likelihood of black ice during early morning and evening hours, particularly on less-traveled roads.
Residents are encouraged to monitor updated forecasts, check PennDOT road conditions before traveling, and keep winter safety kits in vehicles. This late-December pattern is a classic setup where small temperature changes can lead to significant impacts.
