Deep South in deep freeze as brutal cold grips the Midwest

CNN reports:

The deep freeze gripping two-thirds of the United States has temperatures plummeting to unbelievable lows Monday.

Much of the country will see the coldest temperatures in almost 20 years, the National Weather Service said. Some cities will experience chills 30 to 50 degrees below average.

To put things in perspective, the weather in Atlanta and Nashville on Monday will be colder than in Anchorage, Alaska.

And by Wednesday, nearly half the nation will shudder in temperatures of zero or lower, forecasters said.
