An arctic blast dumping snow on the Midwest on Sunday is expected to eventually cover two-thirds of the nation and bring record cold to the South.

The Arctic blast broke off from the polar vortex above Canada, sending the cold air south. New York Gov. Kathy Hochul characterized it as the first winter storm of the 2025-26 season.

A list of National Weather Service bulletins Sunday shows more than 105 million people are the subject of advisories, watches and warnings on freezing conditions, winter weather, and lake effect snow.

The blast is forecast to spread across the eastern two-thirds of the nation, and it could bring freezing temperatures to much of the South by Tuesday while setting low temperature records, the weather service said in Sunday's national forecast discussion.
