At least 49 daily record lows were set across the country Tuesday morning, thanks to a fierce cold snap that's bringing the coldest weather in decades to portions of the central, eastern and southern USA.
Bitterly cold air straight from the Arctic, courtesy of the polar vortex, will continue to shatter records through Tuesday and into early Wednesday before moderating temperatures return by Thursday and Friday.
