"Life-Threatening Cold" Enters The U.S.

A blast of Arctic air is engulfing the U.S. this week, bringing "life-threatening temperatures and record-breaking wind chills" to tens of millions, reports the FOX Forecast Center. Texas could experience cold rivaling the deadly freeze of 2021.

The extreme cold will persist through the end of February, with a wide swath of the country enduring 30 to 50F below average.

The harshest extremes will grip the north-central U.S., where wind chills of -60F are forecast.

The likes of North Dakota, Montana, and Minnesota are forecast deadly conditions, with frostbite becoming a near-instantaneous threat to exposed skin. The National Weather Service has issued 'Extreme Cold Warnings' across these regions, urging residents to take immediate precautions.
