Ullr has a soft spot for the east and before it gets really warm for a few days, he's really pouring it on the almost Polish-Russian areas of the Eastern Alps.
But where exactly? There should be plenty of fresh snow from the Karwendel to the Rax
The center should lie in a very narrow corridor between Upper Austria and Salzburgerland. But - and now we come to the reason why the oracle waited so long to provide information - as the whole thing lies on an air mass boundary and is caused by the warm air masses pushing in, this corridor can also move back and forth and in this case it will decide whether there is 40 cm or a meter of fresh snow. The current status is: Arlberg nothing. Up to the Nordkette 0-40 cm From the Nordkette eastwards 40-60 cm and in the core (see above) up to north-western Styria 70-100 cm of snow. From the Loser (please giggle briefly and vigorously) to the east then again 50-80 cm to the end of the Alps. You can see how close together it all is. If it shifts a little, 100 km can make a huge difference. The main precipitation starts on Friday evening and ends on Saturday morning. The core will move along the air mass boundary from east to west, so the largest amounts will actually fall in the west just before the lift opens.
It is uncertain to what extent the whole thing can penetrate to the main ridge and to what extent damming effects can intensify this. However, as the whole thing is quite warm and is therefore constantly subsiding, I don't think that there is more than 10-20 cm extra in the usual holes. In any case, I would be very surprised if the 100+ were reached at all. And that brings us to the main problem, the heat. Tendentially, the snow line should be lower in the east than in the west, but since warm air is pushing in, it's very difficult to forecast. At 2000 m it will be between -2 and -4/5 degrees Celsius depending on the area, but there should still be enough snow in the east down to 1000 m and lower. In the west, it will certainly rain in some places up to 1300 or 1400 m during the main precipitation. As an extreme range, I would say that the snow line could be between 600 and 1600 meters. From east to west. In general, however, you should be on the safe side in the core areas above 1000-1200 m. I can't say for sure whether it will break up on Sunday. But I wouldn't rule out a few gaps in the precipitation core towards the Salzburger Tauernhauptkamm. In the medium term, it looks bleak until January 10/11, but after that more exciting options will open up on the weather stock market. From mid-January, hopes for better quarterly figures from UllrAG will increase. Fingers crossed. So you in the East: Praise Ullr and see you next time. Powder to the People Your Oracle
