The areas & period
This first alert goes until Monday morning and actually it would be wiser to wait until tomorrow morning as I'm breaking my 48 hour rule here, but it's relatively clear what's supposed to happen and only then will there be a small break in the precipitation and I'm probably quite busy at the weekend too.
The areas are essentially the entire northern slope of the Alps from northern France to the Rax, although the focus will probably be from northern France to the Arlberg due to the position of the trough. Some models are also expecting something in the south/southeast due to leeward developments over northern Italy, but I'm rather skeptical about that.
The snow line: will no longer be a problem from Saturday evening and it will snow all the way down to the green meadows.
