Power of incoming coldwaves in Europe is documenting a map of expected snowing occurrence of snowfall from tropicaltidbits.com – until 5. January (next 16 days) is snow expected almost in all Europe, what is evidence of cold phase of circulation over Northern Hemisphere.
Although a week before the Christmas, extremely warm winter weather surprised not only Mediterranean (Kerkyra, Greece, +22,2°C Palma de Mallorca, +20,2°C, but too Norway – Tafjord with anomalous +17,0°C!), very good news for lovers of winter are coming – next decrease of AO and NAO indices will be accompanied with big cooldown at Christmas 2020 and strong frosts during celebration night from 31. December 2020 to 1. January 2021!
3 Christmas days (24., 25. and 26. December) will start already on Thursday, 24. December with extremely warm weather in continental Europe, with maximum temperatures up to +15°C (!) (British Islands will be already under the effect of polar vortex part, with regional snowing in colder regions), however, big surprise is prepared for central part of continent – mainly Alpine and Carpathian areas – during Friday, 25. December and Saturday, 26. December, instead of +15°C in lowlands should report Munich, Prague, Vienna or other metropolitan cities in the region all-day frosts, minimally on Saturday.
E.g. Munich should experience with cooldown 16°C during the Christmas (23.12. maximum temperature +14°C, 26.12. only -2°C and snow cover).
