Pittsburgh, PA – Drivers across western and northern Pennsylvania could see slick roads tonight as a passing weather system brings light to moderate snowfall, with the highest chances concentrated along the Interstate 80 corridor.
According to the National Weather Service Pittsburgh, snow is expected to develop Tuesday evening and continue overnight into early Wednesday. Forecast totals range from 1 to 2 inches along and north of I-80, including areas near Clarion, Oil City, Mercer, and Butler, while locations farther south — including Pittsburgh, Washington, and Wheeling — may see around a half inch or less.
Probability maps released Tuesday morning show a 60–70% chance of at least one inch of snow across much of northern western Pennsylvania, with chances decreasing sharply south of the city. Areas east toward Johnstown and the Laurel Highlands may also see light accumulations, though confidence there is lower.
Forecasters say the snow will be relatively light but could still create hazardous travel conditions during the Wednesday morning commute, especially on untreated roads, bridges, and elevated surfaces. Visibility reductions are also possible during heavier bursts.
The system is expected to exit by early Wednesday morning, with no major long-duration impacts anticipated. However, even minor snowfall can lead to spin-outs and delays, particularly along I-80, Route 8, and Route 28.
Residents are encouraged to allow extra travel time, monitor local forecasts, and use caution if traveling overnight or early Wednesday.
