Dull, murky weather with fog in some valleys but on the hills in many areas from lower slopes up. Highest cloud base will be on western mountains, and mainly in NW Scotland will break up. Fairly light wind. Higher Scottish summits sub-freezing.
Headline for Cairngorms NP and Monadhliath
Locally blustery; fine, many western summits clear of cloud.
How windy? (On the Munros)
Southeasterly, 20 to locally 30mph.
Effect of wind on you?
Mostly small, although will impede ease of walking on some higher mountains.
A little rain, mainly east; light snow higher tops.
Patchy drizzly light rain, or above 900-1100m snow, most prevalent summits accessed from Deeside; rain less likely elsewhere, and very likely dry west of the A9.
Cloud on the hills?
Extensive on higher areas
Low cloud will very likely shroud areas accessed from Deeside above 400-700m, lowest east. Elsewhere, typical cloud base 700-900, but on Northern Cairngorms & Monadhliath, the cloud may lift above 900-1100m and possibly break up temporarily.

Less than 10% southeast to 20% west of A9
Sunshine and air clarity?

How Cold? (at 900m)
Close to 0C from about 900-1000m up; perhaps a slight frost in some glens after dawn.
All mountain areas of Britain from Friday 28th November 2014
The remnants of the murky weather with low cloud will persist through the weekend, but slowly transitioning to fog in the valleys and some lower slopes, whilst above an inversion, many mountains enjoy superb visibility and very warm. A front will move southeastwards on Monday, followed over 48 hours by cold air (sub-freezing above typically 800m). Then as pressure builds from the south, becoming fine most areas, but frequent snow showers and upland gales on Tuesday and perhaps Wednesday W Scotland. The fine weather may then extend to the north of Scotland. Thus little prospect of significant snowfall.
