Arctic cold weather: Preparations made as U.S. braces for freezing temperatures, snow

Preparations are underway as an arctic blast dives into the nation's interior and southern regions and pushes a snowstorm into the Mid-Atlantic and Northeast that will be followed by lethal cold.

Preparations are underway as an arctic blast dives into the nation's interior and southern regions and pushes a snowstorm into the Mid-Atlantic and Northeast that will be followed by lethal cold.

In key messages on the icy atmosphere, the National Weather Service said today that it would produce "the coldest air of the season thus far, and in many cases the coldest in several years."

High pressure over Canada was pushing the arctic air south and east, with only the regions west of the Rocky Mountains spared its sting, federal forecasters said.

In fact, more than 212 million people, amounting to nearly two-thirds of the U.S. population, were under winter weather watches and alerts, including winter storm warnings, winter weather advisories and extreme cold watches Saturday evening.

At the same time, the air mass was finding friction amid the warmer air and fertile precipitation of the Gulf Coast and Deep South, an altercation feeding a snowstorm and cold wave expected to move across Texas, the Gulf Coast, the Deep South, Mid-Atlantic, the Northeast and parts of New England, weather service forecasters said.
