In reply to ruby2: I was in Llangynog over the weekend and there was about 1 or 2cm, it did thaw quite a lot on saturday and the snow level receeded to about 400m but it then froze hard over night and started snowing again on Sunday and I expect they had more yesterday.
I can JUST see them from the top fields of the farm. Earlier today they looked grey rather than white. I suspect there is maybe an inch, but nothing significant.
