Milder temperatures may have set in along the eastern seaboard, but residents of the Great Plains and other parts of the northern United States are still being warned to avoid going outdoors, where the wind chill makes it feel like 55 degrees below zero on Sunday.
The National Weather Service warning says that the bitterly cold temperatures in North Dakota continue to pose a threat to human life.
The NWS says that a few minutes' worth of exposure to the air could result in frostbite.
It is urging residents of the states that border Canada as well as those nearby to stay indoors.
If it is necessary to go outside, the service advises that residents wear multiple layers of clothing.
The subzero temperatures have broken record lows in the Midwest and the Plains this weekend.
While actual temperatures are in the 20s and 30s, the wind chill factor has at times made it feel as low as minus 40, according to The Weather Channel.
Residents of wide swaths of the US stretching from North Dakota and Minnesota to as far south as Oklahoma and the Texas Panhandle have seen wind chills dip below zero.
The bitter cold late Saturday night smashed records in Denver (-15 degrees); Bismarck (-31 degrees); Valentine, Nebraska (-27 degrees); Amarillo, Texas (0 degrees), and Dodge City, Kansas (-8 degrees).
It's not that bad I walk like two hours every night and sure, when I get home I need both hands to turn the key in the lock, and maybe it takes another 10-15 minutes before I'm able to untie my shoelaces, but now I feel fine.
