The snowline is at Currie level (it's quite a spectacular line across the hillside looking up from Hermiston area). There's nothing in the city but a couple of inches lying in Currie and I'd imagine much more higher up.
I was out on the roadbike yesterday morning – went Livingston – Kirknewton – Lang Wang – Balerno – Riccarton and back home along the A71 and it was grim as a very grim thing – dry when I set off, sleet by Kirknewton, snow on A70 into Balerno, sleet by Currie, rain by Riccarton and turned back to sleet in East Calder. Not remotely nice.
There's a lot of snow above Kirknewton and Balerno and it froze last night so will be pretty icy.
I wouldn't bother with Pentlands for a while.
