In reply to jacobfinn: I went out for a short tour today up Glenshee. "Spring" snow at all levels, heavy slush below ~750m, still raining at 1000m. Snow from 900m upwards was firm, and even icy in places underneath a soft surface - especially where it's been exposed to the wind. It didn't freeze in Braemar last night, was cloudy/raining overnight. Skins on at the car park, loads of snow above 900m and most of the pistes are complete. Cairngorm has had significantly more snow too I believe.
Freezing level is forecast for about 900m tomorrow, I suspect the climbing above this level will be quite good, although I don't know how much snow the buttresses will have hung on to so it may have to be gullys. Will be very icy underfoot once it freezes.
