Johnstown, Pennsylvania – Snow will begin around 1 a.m. Sunday, and up to 10 inches could blanket the Laurel Highlands before the storm tapers early Tuesday, threatening power lines and major travel corridors.
According to the National Weather Service in State College, a Winter Storm Warning is in effect for Cambria and Somerset counties from 1 a.m. Sunday until 1 a.m. Tuesday. Forecasters expect 6 to 10 inches of total snowfall, with locally higher amounts on ridgetops due to upslope enhancement. Wind gusts could reach 40 mph, increasing the risk of downed tree limbs and sporadic power outages.
Statewide impacts will center on central Pennsylvania’s higher terrain. In Johnstown and Somerset, snow-covered roads could develop before sunrise Sunday and worsen through Sunday night. The Pennsylvania Turnpike, U.S. Route 219 and Route 30 may become snow-packed and slick, especially across exposed mountain ridges. Blowing snow could reduce visibility at times and create drifting along open stretches.
Travel could become very difficult to impossible, particularly during the Monday morning and evening commutes. Residents are urged to delay non-essential travel, dress in layers if heading outdoors and monitor PennDOT’s 511 system for live road updates. The warning remains in effect through early Tuesday, and additional advisories could follow if snowfall totals trend higher.
