Arctic Blast Hits US: Polar Vortex Unleashes Deep Freeze

A weakening polar vortex is currently allowing frigid Arctic air to sweep across the eastern United States, driving temperatures to dangerously low levels, especially in the southeast. This phenomenon, characterized by a large area of circulating cold air above the North Pole, is expected to bring a severe cold snap to the region.

Atlanta is anticipating a significant winter storm on Sunday, January 25, 2026, following a period of rain and potential ice accumulation starting Saturday, January 24. Forecasters warn that this ice could create hazardous road conditions and bring down trees and power lines, potentially leading to widespread power outages.

The National Weather Service has indicated that while Atlanta and North Georgia will experience freezing rain, widespread snow is unlikely. Residents are advised to stay informed through local alerts and prepare for potential disruptions to essential services like power, with Georgia Power offering a live outage map for tracking.
