Harrisburg, PA — Pennsylvania could face a major winter storm this weekend, with snowfall totals ranging from several inches to as much as 24 inches, depending on the exact track of the system.
According to the National Weather Service, forecasters are now focusing on two remaining storm scenarios, both of which would bring snow to Pennsylvania, but with vastly different impacts.
In Scenario 1, the storm tracks farther south before curving north toward the Mid-Atlantic coast. Under this outcome, much of Pennsylvania would see lighter accumulations, generally 1 to 6 inches, with the heaviest snow staying south and east of the state. This scenario is currently considered less likely, though still possible.
In Scenario 2, the storm tracks farther north along the Appalachian spine, placing central and eastern Pennsylvania closer to the storm’s core. This would significantly increase snowfall potential, with 12 to 24 inches possible across parts of central Pennsylvania, the Susquehanna Valley, and into northeastern Pennsylvania. Higher totals exceeding two feet could occur in the higher elevations of the Poconos and central mountain regions.
Snow is expected to begin Saturday night, become heavy at times Sunday, and continue into Monday, with cold temperatures ensuring snow remains on roadways. The National Weather Service warned that travel conditions could become dangerous or impossible, particularly if the heavier-snow scenario develops.
Probabilities for 6 inches or more of snow are already above 60% across much of Pennsylvania, rising to 80–90% in eastern and mountainous areas, according to the latest guidance. While a Winter Storm Watch has not yet been issued statewide, forecasters say one is likely within the next 24 hours if trends continue.
Residents are urged to prepare now by adjusting travel plans, stocking emergency supplies, and ensuring vehicles and heating systems are ready. With an extended cold period expected after the storm, impacts could linger well into next week.
Additional updates are expected as forecast confidence continues to increase.
