In reply to NIGBEE: It's been raining pretty heavily both yesterday and this morning; It seems to be falling as rain higher up because the temperatures have risen quite a lot.
I'd say it was snow free; the snowdon webcam shows a pretty snowless snowdonia as well.
I'm sure someoen that's headed up this week will be able to tell you more accurate conditions though.
I'd say you probably wouldn't need crampons and an axe.
