At Cape Girardeau, Missouri, this morning, the temperature dropped to a record -19F (-28C), breaking the old record of -18 F set in January 1977.
This breaks the record, not just for the date, but for all time.
Old Man Winter will be unrelenting across the Midwest and Northeast this week as yet another blast of arctic air spreads deep into the South and off the Atlantic coast, says meteorologist Briam Lada.
Some southern cities forecast to dip into the teens – or even lower – include Birmingham, Alabama; Charlotte, North Carolina; Columbia, South Carolina; Nashville and Atlanta.
In Florida, temperatures will dip down to the lower 30s in cities such as Orlando, Melbourne and Daytona Beach.
In the mid-Atlantic, some daily record lows set during the late-1800s will be challenged.
