Freezing temperatures are set to grip the eastern United States as the polar vortex plunges southward.
Meteorologists warn that the South-East and East Coast will experience temperatures far below average through mid-January. Even typically warmer areas like Florida and the Gulf of Mexico may face sub-freezing conditions.
Heavy snowfall is predicted for the Great Lakes region and the Appalachians, with bitterly cold wind chills sweeping across much of the country.
What is a Polar Vortex?
The polar vortex is a mass of frigid air circulating around the Arctic. When it shifts and expands, it brings icy temperatures to regions farther south than usual. Independent forecaster Atmospheric and Environmental Research models show the polar vortex expanding over the U.S. in early January, driving a significant cold snap.
The National Weather Service (NWS) warns of “the coldest air of the season” and dangerous wind chills across the south-east. Lows could plummet to -8°C (18°F) in Texas and -4°C (25°F) in Georgia, while northern Minnesota faces bone-chilling -25°C (-13°F).
Snowfall and Wind Chill Risks
By the second week of January, heavy snow is expected from the Great Lakes to the central and eastern U.S., with the possibility of snowfall as far south as Texas. Though significant accumulation isn’t forecast for the South-East, even light snow could cause major disruptions in areas unprepared for icy conditions.
Hazardous wind chills in northern states could drop to -29°C to -34°C (-20°F to -30°F), posing a severe risk of frostbite on exposed skin within 30 minutes.
Comparisons to 2022 Arctic Storm
The current forecast brings back memories of the devastating Arctic winter storm of 2022, which caused widespread power outages, halted oil production on the Gulf Coast, and resulted in multiple fatalities.
As the coldest weather approaches, experts advise taking precautions to stay safe and avoid travel in affected regions.
