Sweet shots on the blog Mark...
I reckon the backs have been catching lots of snow. During the clear spells today you could see the SW faces were a bit scoured so the NE faces should be getting loaded. That's backed up looking at the high res version of the pic I posted a link to (thanks Great Glen Game). You could see cornices developing above Winger Wall and that has to be a good sign that the snow is going in the right direction.
Looking at the forecast seems like more snow tonight, dry tomorrow, more snow tomorrow evening, then a very brief warm up Thursday, but with more wet snow either side. [

Infact a very brief warm up followed by more snow is just what is needed to consolidate the snow and give a base. IF Nevis were open Saturday there could be a fairly mature snowpack in the backs with some lines pretty well filled in, might even be worth the hike....
