Well, the Cairngorm summit temp data wasn't that promising yesterday with the temp hovering around zero. Unfortunately it stopped transmititng for some unknown reason last night (it still seems to be off line) so as i'm generally an optimist Roger and i went for a look. He wasn't as optimistic as i was (more realist!) and we weren't really in a rush. It was 6 deg when we left the ski car park at 11.15 this morning and it was either as warm or warmer in the corrie which was shrouded in damp mist, thus preventing any real temp gradient with height.
There is snow in many of the gullies and when it re-freezes they should provide good sport on neve. There is some ice growing and if the thaw is short and not accompanied by heavy rain several routes should have ice in the corners which the old school will love and the new school hate!
We didn't do any climbing and went for a coffee. Note that when we looked back to the corries on the walk out they looked significantly blacker an hour later (we had lunch behind a boulder) as a fine drizzle was falling.
Sunday may be OK for the easy gullies and selected mixed climbs but i'm not sure how much riming on the steep routes will occur on Saturday.
