Philadelphia, PA – An intense arctic outbreak is expected to bring extreme cold and dangerous wind chills across Pennsylvania, New Jersey, and the Mid-Atlantic this weekend.
According to the NOAA National Weather Service Weather Prediction Center, frigid air and strong winds will spread into the region beginning Friday evening, with the most severe conditions expected from late Friday night through Sunday. Wind chill values are forecast to drop to around minus 20 degrees across much of eastern Pennsylvania, New Jersey, and parts of the central Mid-Atlantic.
Across Pennsylvania, including Pittsburgh, Harrisburg, Allentown, and Scranton, overnight temperatures are expected to fall into the single digits and below zero. Gusty winds will push wind chills into the minus teens and minus 20s, creating hazardous conditions for anyone outdoors. Similar wind chill values are expected across New Jersey, including Newark, Trenton, and Atlantic City, despite slightly higher air temperatures near the coast.
Daytime highs over the weekend are forecast to remain in the teens to low 20s, with wind chills staying below zero for extended periods. The coldest conditions are expected Saturday morning and again early Sunday.
Travel impacts may occur along major corridors including I-95, I-80, I-78, I-76, and the New Jersey Turnpike. While widespread snowfall is not expected, brief snow squalls and blowing snow could develop, especially in central and western Pennsylvania, causing sudden drops in visibility and icy patches.
The Weather Prediction Center warns that frostbite can occur on exposed skin in as little as 15 to 30 minutes under these conditions. The extreme cold may also strain heating systems and increase the risk of frozen pipes.
Commuters, students, and weekend travelers are urged to limit outdoor exposure, dress in layers, and prepare vehicles for severe cold. A gradual warming trend is expected to begin early next week, though temperatures will remain below normal.
