An Arctic blast gripped the northern Plains, Midwest and Great Lakes Saturday morning, with millions of Americans under freeze warnings.
Six million people were under winter alerts Friday from northern Minnesota into upstate New York, as snowfall totals downwind of lakes Erie and Ontario were expected to reach 3 feet or more.
The National Weather Service warned that the Arctic airmass is delivering the coldest temperatures since last winter. Wind chills in the northern Plains and upper Midwest are expected to plunge below zero Saturday morning. Parts of North Dakota could experience wind chills as low as minus 30 to 40 degrees, according to the agency.
The highest snow accumulations are expected east of Lake Ontario, where some isolated areas could be hit by up to 60 inches of snow by early next week around the Watertown, New York, area, the National Weather Service said.
New York Governor Kathy Hochul declared a state of emergency Friday for several counties, including Erie and Oswego. At times, snowfall rates will be blinding, at 3 to 4 inches an hour, and could be accompanied by thundersnow, a rare weather event that combines a snowstorm with thunder and lightning, creating hazardous travel conditions.
By Friday night, more than 20 inches of snow had already fallen along Lake Erie’s shores in parts of Ohio, Pennsylvania, and New York, according to the National Weather Service.
Erie, Pennsylvania, recorded 30 inches, the highest total so far, according to the agency.
Travel disruptions have choked post-Thanksgiving travel plans, especially along Interstate 90 between Cleveland and Buffalo.
The interstate was closed in Pennsylvania late Friday afternoon, between interstate 79 to the New York state line, Erie County Executive Mark Poloncarz, of New York, said during a news conference. Other possibly affected thoroughfares include Interstate 81, north of Syracuse, New York.
The National Weather Service said Friday that travel “could be very difficult to impossible” in spots downwind of the Great Lakes.
Other possibly affected thoroughfares include Interstate 81, north of Syracuse, New York. The “Sunday Night Football” face-off between the San Francisco 49ers and the Buffalo Bills could be buried under snow because Highmark Stadium is in Orchard Park, a town that is forecast to pick up between 12 and 18 inches, with higher amounts possible.
The Buffalo Bills posted Friday on X, for their diehard fans, dubbed the “Bills Mafia,” to register to shovel snow at the stadium.
Poloncarz said during the media briefing that central and southern Erie County will most likely be hit the hardest, with the majority of the snowfall arriving on Saturday and Sunday. The central regions of the county could see between 2 and 3 feet of snow, while the southern area of the county could see more than 3 feet, Poloncarz said.
Meanwhile, some 9 million people on Friday were under freeze watches and warnings across the South, stretching from Texas to the Carolinas.
A vigorous lake-effect snow event blanketing areas downwind of the Great Lakes, is expected to taper off early next week. But weather forecasters warned that colder air was still headed South, with an Arctic air mass spilling south out of Canada.
