Snow advancing from the south during morning, likely most persistent areas Skye to Kintail. Through the day slowly all turning to rain up to higher slopes. Whiteout very likely.
Cloud on the hills?
Extensive, particularly south
Northern summits may be clear for a few hours, but as precipitation develops, expect cloud widely lowering to shroud hills, to low levels coastal areas south from Torridon.
Chance of cloud free Munros?
30% north; soon almost nil south& west.
Sunshine and air clarity?
Sunshine unlikely, at best hazy through high cloud far north around dawn. Visibility becoming very poor, often appalling due to low cloud and snow/rain.

All mountain areas of Britain from Wednesday 2nd December 2015
Continued bouts of severe upland gales over the next week to 10 days, although a possible lull in Scotland on Thursday this week, and perhaps England & Wales on Friday. On western mountains, precipitation at some stage almost daily resulting in considerable rainfall in total. Freeze-thaw cycles will occur on the Scottish Munros, although often sub-zero, allowing snow to accumulate. Further south, higher summits occasionally be below freezing point, but lying snow fairly transient.
