Areas:
Ullr seems to be losing the battle for the Alps - slowly but surely - but in his rearguard action with climate change (or extremely annoying permanent weather conditions) he at least remembers to put the snow where there is already a base, namely the Southern Alps from Piedmont to Ticino.
The snow line:
Not a problem, as it only slowly rises towards 1200-1500m during the precipitation and there was no snow below 1800-2000m anyway. It's difficult to say whether there will be enough snow in the trees somewhere by Wednesday morning to still be able to get in.
The wind:
Will be quite draughty and will therefore blow a lot. Be aware, especially in the areas with less thick bases, that everything underneath is likely to be converted and read the LLBs.
The volumes:
The boundaries of the core are very tight and small-scale displacements can have a big impact. At the moment, it looks like the largest volumes are from Gran Paradiso to Piedmont. Ticino, the French Maritime Alps, Monte Rosa and the Simplon could see similar amounts, but at the moment it looks like a little less. It definitely won't be anything further east in the Southern Alps and generally everywhere in the north. You can play it safe in the Turin Alps, the Italian-French border as far as Piedmont, whereby the Italian-French border is significantly higher and has benefited from the November snowfalls.
In the core, 50-80cm of snow should fall across the board, possibly up to 1m in isolated cases. In the neighboring areas it will be 20-60cm with the higher amounts towards the core area.
