Summary for all mountain areas
Higher areas, mainly Scottish Highlands frozen, and frost some valleys at first. Otherwise, benign as from the west the northerly wind drops and snow and hail showers become isolated.
Headline for West Highlands
Higher areas frozen. Bright sunshine. Wind dropping.
How windy? (On the Munros)
Northerly gradually backing west or southwesterly. A prolonged lull to 10mph after 25mph toward central highlands at dawn.

Mostly negligible
How Wet?
Precipitation not expected
Cloud on the hills?
Varied; some higher tops clearing, others remaining in cloud.
Generally, cloud base 900 to 1200m. The cloud will lift off many higher summits, particularly south of Lochaber but 'hang' on some slopes and corries most or all day. Cloud may begin to shroud west coastal slopes at 300-450m after dusk.
Chance of cloud free Munros?
50% Lochaber to 80% elsewhere by afternoon
Sunshine and air clarity?
Bright sunshine, unbroken Loch Lomond NP and Arran. The air very clear so excellent visibility, but fog some valleys and higher slopes.

A long series of Atlantic lows passing north of or across Britain will bring high rainfall to western mountains together with frequent upland gales (sometimes storm force) and low cloud. Temperatures on higher tops sometimes below freezing point, particularly at the weekend in Scotland, but elsewhere fresh snow transient.
