Polar vortex may bring arctic air to U.S. this winter, affecting New York temperatures

The polar vortex may influence U.S. winter weather, particularly in New York, by potentially allowing arctic air to enter the region late in the season. This phenomenon typically occurs when the polar vortex weakens, disrupting its usual pattern. Currently, forecasts suggest a milder winter overall, with a strong polar vortex expected in January. However, historical patterns indicate that disruptions can lead to colder conditions towards the end of winter, lasting several weeks. Meteorologists are monitoring the polar vortex closely, but predicting specific impacts months in advance remains challenging. Any disruptions could affect North America, Europe, or Asia, depending on prevailing weather systems.
