Two-thirds of the continental United States will be a frozen ice box on Tuesday, as the so-called polar vortex of frigid Arctic air spins across the US Midwest, clips the Great Lakes, the Ohio Valley and pushes on into New England.

The sub-zero cold and bitter winds will stick around for a couple of days, possibly bringing dozens of record lows with a life-threatening freeze before dissipating by the weekend, the National Weather Service reported (NWS).

The polar vortex is a mass of freezing air that normally spins around the North Pole, but has slipped southwards and swirled into the US, forecasters said.

The hardest-hit area will be the Midwest, where wind chill could take temperatures as low as minus 46 degrees Celsius (minus 50 Fahrenheit) in the Chicago area by Tuesday evening, the NWS reported.
