Buffalo, New York – A powerful winter storm is expected to impact much of Pennsylvania and New York beginning Sunday night, bringing heavy snow, dangerous cold, and periods of ice that could significantly disrupt travel and daily life across the region through early next week.
According to the National Weather Service, snow will spread from western Pennsylvania into much of New York late Sunday, becoming heavy at times through Monday. Arctic air surging in behind the system is expected to drive temperatures well below normal, producing dangerous wind chills and increasing the risk of frostbite during overnight hours and early morning commutes.
The most significant impacts are expected along major corridors including Interstates 90, 86, 80, and 81, where snow-covered and icy roads could develop quickly. Western and central New York, including areas east of Lake Erie and Lake Ontario, may see enhanced snowfall, while northern and central Pennsylvania faces the potential for prolonged accumulating snow. Southern sections of the region could also see periods of sleet or freezing rain, raising concerns for scattered power outages.
Officials urge residents to avoid non-essential travel during periods of heavy snow, prepare vehicles with winter emergency kits, and ensure heating systems are operating safely. Prolonged cold may strain utilities and increase the risk of frozen pipes.
Winter storm warnings and cold weather advisories are expected to remain in effect through Tuesday, with additional alerts possible as conditions continue to evolve across Pennsylvania and New York.
