Earlier this month, a sudden atmospheric warming event caused the Arctic's polar vortex to reverse its trajectory. The swirling ring of cold air is now spinning in the wrong direction, which has triggered a record-breaking "ozone spike" and could impact global weather patterns.

Signs of Early Weakening in the Arctic Polar Vortex Raise Alarms for a Severe Northern Hemisphere Winter The polar vortex, a persistent upper-level wind circulation in the stratosphere over the Arctic, is exhibiting early indicators of weakening as of November 2025, according to analyses from the NOAA Climate Prediction Center and associated atmospheric monitoring efforts. This vortex typically forms a robust barrier of westerly winds encircling the North Pole at altitudes between 10 and 30 mile

POLAR VORTEX SPLIT | It is true that a sudden warming event in the Arctic will eventually lead to a chunk of the polar vortex flooding into the eastern United States. How extreme this cold outbreak will be remains to be seen, but you can pretty much set your clock to feeling the effects about 2 weeks after the process gets underway. That would put us in mid-late January (start time likely after the 15th, but before the 20th). Again, specifics like highs/lows, snow, etc just can't be nailed down
