Wider weather episode

An area of low pressure across New England began slowly moving westward during the late evening hours of November 21 and into November 22, 2024 allowing for a long-duration snow event for portions of central Pennsylvania. A strong pressure gradient northwest of the area of low pressure also allowed for gusty winds throughout the event with a wet snow prompting multiple trees and wires down throughout portions of Sullivan County, resulting in over 70% of the county having no power. There were also multiple roads closed across portions of Cambria and Somerset Counties with disabled vehicles, trees/wires down, and jack-knifed trailers.
