• A burst of Arctic air that AccuWeather meteorologists have been monitoring since last week is poised to plunge the eastern two-thirds of the United States into a deep freeze ahead of Christmas, bringing the coldest air in decades to some areas and causing heating demands to sky rocket.
• Subfreezing and, in some cases, subzero temperatures are expected to grip areas from the northern Rockies to the Plains, East and South. The mercury could dip to 25-50 degrees Fahrenheit below late-December averages during the height of the cold.
• “The Arctic air can envelop much of the central and eastern part of the country just prior to the holiday weekend, threatening the coldest pre-Christmas stretch in decades,” AccuWeather Meteorologist Elizabeth Danco said.
