Arctic cold front to bring season's coldest temperatures to Florida over Christmas weekend

An arctic cold front blasting much of the U.S. with dangerously low temperatures is moving closer to Florida.

The front hit the central Plains Wednesday and forecasters warned residents temperatures could dip by 20 or more degrees within just a few hours.

More than 50 million Americans were under a wind chill warning Wednesday as the brutal cold and dangerous wind chills threatened the northern Plains en route to the East Coast by Friday.

The front is forecast to arrive in Florida Friday. The Panhandle and North Florida could see the coldest temperatures, with lows falling below freezing through the holiday weekend. Freezing temperatures could dip as low as Central Florida, include Tampa and Orlando.

Saturday morning, wind chills could make Florida temperatures feel like 10 degrees in Tallahassee to 33 in Naples.

Will the cold front affect holiday travel?

As more than 112 million people prepared to travel at least 50 miles for the holidays, according to AAA, the storm – expected to rapidly intensify into what's known as a bomb cyclone this week – could create dangerous air and road travel, forecasters predicted.

The National Weather Service warned of whiteout conditions on roads in the central and eastern U.S. where blizzards occur.

"Traveling in these conditions will be extremely dangerous, to at times impossible," the National Weather Service said. "You risk becoming stranded and more vulnerable to the bitterly cold weather."

More than 1,200 U.S. flights were canceled and another 676 were delayed Thursday as of 6:30 a.m. ET, according to the flight-tracking website FlightAware.
