The good thing first: there's enough for an alert until Sunday. But it will be very warm after the snowfall and the limit will also rise during the snowfall, so you have to go high on Sunday if you still want to find powder in the northern Alps.
The area:
From the Bernese Alps to Salzburgerland in the east.
The wind:
Will probably be moderate to strong, but as you have to go very high up, it will have blown strongly where there was still powder on Sunday. As it has a strong westerly component, I would try my luck in higher areas that could benefit from it. It should also reach the main ridge this time.
The snow line:
Starts quite low everywhere and rises from west to east to 1500-1700m by the end of the snowfall. In the east, this won't happen until Sunday night, but even there it rains quite high before the precipitation stops.
The amounts:
Widespread snowfall of 20-40cm above 1800-2000m is possible, with 40cm being the upper limit, which will only be reached in the snow holes. The models have more in them at certain points, but I say that these are model errors rather than opportunities. But if someone finds 50cm in a high alpine west/northwest snow hole, they should consider themselves very lucky. I don't think that will happen.
Where to go with my climate-friendly bamboo bike?
If you want to set off today, you should still head for a glacier or a ski resort that is well above 2500m on Sunday, otherwise there won't be much powder even on the north side with a zero degree limit of 3000m. Today, on Saturday, I would only play in the higher trees if I was there anyway, had a season pass or really wanted to do a tour. Most of it won't be here until tonight anyway.
In the medium term:
...it will remain snowy after the brief warm peak and fields of precipitation from the northwest are expected to approach the Alps from time to time. Whether this meets the 30cm alarm criteria will be decided spontaneously. Powder to the people! Your oracle
