(CNN) - A snowstorm backed by bone-chilling cold began to push into the Deep South on Thursday, re-enforcing record-low temperatures well into Florida.
A days-long cold spell eased some on Wednesday, but for much of the nation, even lower temperatures are on the way through the weekend. Record-breaking lows are forecast for two-thirds of the country, for most areas east of the Rockies.
The arctic blast that began over the weekend has been blamed for at least seven deaths across the nation.
CNN meteorologist Rob Marciano said some areas in the South will have slightly warmer temperatures on Thursday before it cools off even more. He traveled to Memphis, Tennessee to find out just how cold it really is.
