(CNN) -- The powerful winter storm that moved across the United States this week, dropping record-breaking snow and spinning dangerous tornadoes on Christmas, isn't over yet. It dumped more snow on the Northeast on Thursday and left behind bitterly cold weather, especially in the South. While the Northeast is used to dealing with heavy snow in late December, some parts of the country haven't seen this kind of weather in decades. Canadians were preparing for the white stuff, too. "If you are in Atlantic Canada ... you are just getting going. If you are in New York City the cold air is coming down the Hudson (River)," CNN meteorologist Chad Myers said. "If you are off to the east, you're still going to get snow in Maine on up into New Brunswick. And that snow could be heavy at times. We're talking about another foot in some spots."
