Meteorologists warn: due to the weakened polar vortex, Germany and neighboring countries may be hit by an extremely cold winter. Although experts do not have a consensus, many point to a high probability of Arctic cold spells - especially after the Christmas holidays, reports Euronews.
According to forecasters, the polar vortex this winter appears significantly weaker than usual. It was such a combination in 1978-1979 that led to the 'winter of the century': powerful snowstorms, prolonged frosts, and a transport collapse.
Christmas will be mild, but after that, a sharp cold is possible. Current weather models for the period around Christmas indicate rather mild weather with isolated cold episodes. The European Meteorological Center forecasts a drop in temperatures after the holidays.
The American NOAA, on the other hand, expects above-normal temperatures on average for the month - but this figure is significantly 'pulled up' by the next two weeks, so further cooling is still possible.
Most models indicate a changeable and fairly mild January. However, EFFIS models show a trend towards lower temperatures and less precipitation.
Such a scenario means stable high pressure over Central Europe: calm weather during the day, but at night - severe frosts and fog, causing long-lasting ice on the roads.
An additional risk is the possible disturbances of the polar vortex in the middle of winter, which could suddenly direct Arctic air into Europe.
NOAA climatologists confirm that this year is under the influence of La Niña, which will last at least until the beginning of 2026. This phenomenon usually brings lower temperatures and increased humidity to Western Europe.
For the Alps, this means a higher likelihood of intense snowfall - good news for skiers.
