MWIS has been updated – outlook is:
Cold conditions will persist across all mountain areas for 5 to 8 days (models from most centres suggesting a return to milder
conditions will not now come in until early next week). Most terrain will become frozen, and there will be further snowfall.
Toward next weekend, very likely a couple of fine clear days before winds strengthen ahead of the slow advance of a thaw.
I’d be happy with that area, with options on the hills you mentioned, plus Glencoe not that far away. I also wondered about skiing up Ben Hairy-arse too…
Crianlarich YHA has space, or we could try By The Way at Tyndrum. Given the weather outlook I think accommodation will book up pretty quickly.
