Plattsburgh, NY – An intense arctic outbreak is prompting preparations across northern New York and Vermont as dangerously cold wind chills approach minus 40 degrees this weekend.
According to the NOAA National Weather Service and Weather Prediction Center, a surge of arctic air will overspread the region beginning Friday night, with the most extreme conditions expected late Friday through Sunday morning. Wind chill values between minus 30 and minus 40 degrees are forecast across the Adirondacks, Champlain Valley, Green Mountains, and Northeast Kingdom of Vermont.
Air temperatures are expected to drop well below zero overnight, while strong northwest winds will dramatically increase the danger. Forecasters warn that frostbite can occur on exposed skin in as little as 5 to 10 minutes under these conditions, making the cold potentially life-threatening.
Travel impacts are possible along major corridors including I-87 in northern New York, I-89 across Vermont, I-90 near Albany, and U.S. Route 2 through central Vermont. While widespread snowfall is not the primary concern, blowing snow and brief snow squalls could cause sudden reductions in visibility, particularly in open and elevated areas.
State and local agencies across New York and Vermont are urging residents to prepare for extreme cold by limiting outdoor exposure, checking heating systems, and ensuring pets and livestock have adequate shelter. The cold may also strain power infrastructure and increase the risk of frozen pipes.
Daytime highs through the weekend are expected to remain well below freezing, with some mountain locations staying below zero even during the afternoon. Wind chills may remain dangerously low throughout the day on Saturday.
Commuters, students, outdoor workers, and weekend travelers should plan ahead, carry winter emergency kits, and avoid unnecessary travel during the coldest periods.
A gradual warming trend is expected early next week, though temperatures are forecast to remain below seasonal averages across the region.
