Not only the Alpine region and East-Central Europe but too Balkan!
After extreme blizzard hits the Alps and Central Europe already around Thursday and Friday, 9.-10. December 2021 /https://mkweather.com/bratislava-should-surprise-40-cm-of-snowfall-the-metropolitan-city-is-preparing-for-snow-calamity/; https://mkweather.com/20c-in-austria-before-an-arrival-of-blizzard-20-30-cm-for-vienna-after-blizzard-will-be-even-colder//, blizzard conditions will shift at the weekend and early next week above Balkan Peninsula!
The worst should end mainly in Serbia and Bosnia and Herzegovina, where more than 2/3 of countries should end under masses of snowfall.
In mountainous parts of Serbia and Bosnia and Herzegovina, 20 – 50, regionally 50 – 100 cm of snowfall is forecasted, which should cause significant snow calamity in the region, with widespread problems in roads, highways, railways, power outages, or uprooted trees.
Snowing in the next period is forecasted almost in all Balkanian Peninsula, including Slovenia, central Croatia, Carpathian Romania, western Bulgaria, North Macedonia, or mountainous Albania and Montenegro.
Snow cover should appear in low-situated basins and valleys in Greece and later, Turkey.
After the blizzard, severe frosts up to -20°C are in Serbia, but other Balkan countries, too, are possible already around the next mid-workweek (15. December 2021).
