Extreme blizzard is already until the end of the current workweek forecasted for Austria, Switzerland, and parts of southern Germany, eastern France, northern Italy, or Slovenia.
While in Bratislava should be a little more snow such as in Vienna /https://mkweather.com/bratislava-should-surprise-40-cm-of-snowfall-the-metropolitan-city-is-preparing-for-snow-calamity//, Austrian capital city, or its closer metropolitan region, should surprise 20 – 30, in the warmest parts of the city 10 – 20 cm of fresh snow.
Much worse will be a situation in the Alps, where up to 1 meter of snow is possible just in lower situated basins and valleys below 1000 MASL – including densely populated parts of the country.
A similar situation is forecasted for other mentioned countries and regions.
