More than 100 million Americans are in the path of the storm as it tracks from the southern Plains to the East Coast over the next few days, the National Weather Service said.
But the nation's heartland will get some relief over the weekend, the weather service reported, as the frigid air will begin to moderate over the next couple days.
A magnitude 7.7 earthquake struck the same area last week, triggering a tsunami warning in New Caledonia and its neighbours.
It prompted the National Emergency Management Agency to issue a tsunami threat and urged residents along the country's northern coast to avoid beaches and shore areas.
It told people in or near the sea from Ahipara Bay to the Bay of Islands, Great Barrier Island, and from Matata to Tolaga Bay to move out of the water, off beaches and shore areas and away from harbours, rivers and estuaries.
The warning was lifted after a few hours.
No tsunami warning has been issued today.

Large parts of Syria were covered, including the capital Damascus which is witnessing this winter's first snowfall. Snow was as high as 15 cm (6 inches) in the mountains of Sweida province, according to the official state news agency SANA.
Roads in some provinces were blocked. In the central province of Hama, bulldozers shoveled snow to open roads while vehicles skidded on ice, further causing traffic disruption.
The University of Damascus called off mid-term exams scheduled for Wednesday and Thursday in all its branches around Syria because of the extreme weather conditions. The country's ports remained open.

Here are some of the records that have been broken across the United States by the cold weather as well as some of the more interesting statistics recorded due to the extreme temperatures.
Extreme cold yet a record high
There was a 130-degree spread in temperatures across the US yesterday, from 90 degrees in Florida to 40 below zero in Wisconsin and Minnesota.
The earthquake occurred at a shallow depth of 10 km beneath the epicenter early morning on Wednesday 17 February 2021 at 5:36 am local time. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
Based on the preliminary seismic data, the quake should have been widely felt by almost everyone in the area of the epicenter. It might have caused light to moderate damage.
Moderate shaking probably occurred in Kastraki (pop. 910) located 7 km from the epicenter, Nafpaktos (pop. 13,400) 12 km away, and Aigio (pop. 20,400) 19 km away.
