A severe wave of arctic weather is forecast to sweep across the eastern United States (US), with meteorologists warning of the coldest temperatures in more than a decade. With the addition of a polar vortex, along with significant atmospheric pressure changes, temperatures are expected to run well below seasonal norms. Areas including the Appalachians, the Great Lakes, and the Northeast could experience heavy snowfall and disruptive winter storms, while wind chills in the southeastern U.S. could pose safety risks.

Record-breaking cold weather expected

According to the weather ReportsThe polar vortex — cold, low-pressure air circulating in the Arctic — has spread southward. This change, combined with a high pressure system over Canada, is predicted to bring sub-freezing temperatures to the Gulf Coast and Florida. Reports suggest that some areas could see below-average temperatures of 17 degrees Celsius, with the possibility of rare phenomena such as iguanas in Florida becoming active due to the cold.

Long-lasting arctic conditions

As Reported The Arctic blast is likely to continue into mid-January, with analysts predicting that January 2025 could rival the coldest months on record in a decade, according to Live Science. Paul Pastluk, AccuWeather’s chief long-range forecaster, has highlighted the possibility of multiple Arctic high pressure systems making landfall in the US, which could sustain freezing conditions for days to Live Science.

Potential barriers and safety concerns

Reports suggest that massive disruptions are expected due to heavy snowfall and icy conditions. Power grids in vulnerable areas may be stressed, while poorly insulated homes in southern states may suffer from frozen pipes. Analysts have also noted the possibility of record-breaking cold in states like Virginia, Georgia and Florida.

Preparations and vigilance are advised for affected areas, with officials stressing the importance of safety measures during this severe weather.
