Treacherous weather will maintain its grip on many parts of the United States from Tuesday through Friday, with up to 4 inches of snow and freezing rain expected from the southern Plains into the Northeast, forecasters said.
An Arctic air mass that descended over much of the country pushed temperatures to historic lows on Tuesday, said meteorologist Lara Pagano of the National Weather Service's Weather Prediction Center in College Park, Maryland.
In Lincoln, Nebraska, a reading of minus 31 degrees Fahrenheit (minus 35 degrees Celsius) on Tuesday shattered a record set in 1978 of minus 18F (minus 27C).
In typically toasty Dallas-Fort Worth, minus 1F (minus 17C) broke a record set in 1903 of 12F (minus 11C).
In just Texas alone, there were more than 4.4 million power outages.
Icy roads were blamed for one of the four deaths tied to the bitter cold. The others were identified as a homeless person and two carbon monoxide poisoning victims, said Houston Police Chief Art Acevedo.
- We have snow in Texas. I'm down here in San Antonio where we never see snow. Saw about a foot for the first time since 1985. Hopefully power comes back on soon. Because people are cold. It's freezing inside this house.
