If you think this week is cold, just wait until next week arrives. The fiercest blast of arctic air this season thus far will raid the eastern half of the country.

AccuWeather.com Expert Senior Meteorologist Alex Sosnowski says this could be the most painful cold blast of the entire winter season in many places and the one that people will remember most.

Though the cold will be most extreme as compared to normal across the Southeast, people from North Dakota to New York and Florida will all feel the wrath of this arctic outbreak.
