In early November 2026, the polar vortex is expected to weaken significantly, potentially leading to colder temperatures and increased snowfall in parts of Eastern Europe. This unusual event may result in the earliest recorded sudden stratospheric warming, with air temperatures at high altitudes rising dramatically. Forecasts suggest that by the end of November, Eastern Europe will experience below-normal temperatures and more snowfall, while other regions may see milder conditions. The weakening vortex could also influence weather patterns in December and January, with colder air penetrating Europe and increased snowfall in many areas. The interaction with El Niño may complicate these effects, as it tends to bring warmer temperatures in some regions.
