Areas and time period:
From Saturday morning to Sunday afternoon, alert amounts will be reached from central Switzerland to the far east of Austria. A small core should be on the Arlberg, but the second core from Salzburgerland to Styria should get more.
Snowfall limit:
And there we have the salad, because even if Ullr will initially let it snow up to 1600m in the west and 1200m in the east, the whole thing will gradually rise until Sunday and will probably end up at 1900-2200m in the west and somewhere between 1700 and 2000m in the east. This means that everything below 2400m in the west and 2200m in the east will turn into GLOP ™ by Sunday afternoon. Cold powder, if there was no wind in it, will probably only remain above 2600 or 2400m.
Wind:
Full gale from the west. With the weak foundations everywhere and the considerable amounts of fresh snow in the high mountains (i.e. exactly in the weak layers), this will probably not be an alarm to praise Ullr, because everything will be blown in.
