Pittsburgh, Pennsylvania – Snowfall south of the I-70 corridor Tuesday afternoon may disrupt travel during the evening commute.
According to the National Weather Service Pittsburgh, winter weather is expected to impact portions of western Pennsylvania mainly south of Interstate 70, with the heaviest snowfall rates developing Tuesday afternoon and continuing into the evening hours. Light snow is forecast to begin after 10 a.m. Tuesday, with the most intense snowfall expected between 3 p.m. and 7 p.m., overlapping peak commute times.
Forecasters indicate the highest snowfall totals are most likely in higher elevations, particularly across eastern Tucker County and eastern Preston County, where accumulations could reach the upper end of forecast ranges. Lower elevations across areas near Interstate 79, U.S. Route 119, and surrounding roadways are expected to see lighter totals but still face slick conditions as snowfall intensifies.
While confidence is increasing regarding the timing of snowfall, the National Weather Service notes that the precise location of the heaviest bands remains uncertain. Even so, travel impacts are considered likely, as snowfall rates may briefly overwhelm road treatment efforts during the evening rush hour.
A Winter Weather Advisory remains in effect for portions of northern West Virginia from 10 a.m. Tuesday until 1 a.m. Wednesday. With cold road temperatures, even minor accumulations may lead to slippery roads, reduced traction, and slower travel speeds.
Commuters, students, and evening shift workers are urged to allow extra travel time Tuesday evening, especially on elevated and untreated roadways.
Additional updates are expected as conditions develop.
