Forecast last updated on Monday 10th December 2018 at 3:10pm

Summary for all mountain areas

A murky day for many areas, with widespread fog across the hills, and patches of light rain or drizzle. The far north and northwest of Scotland will fare best for cloud breaks. Winds fairly light, but strengthening through the day on westernmost hills.

Headline for The Northwest Highlands

Largely dry. Some cloud breaks. Wind strengthening to gale force far west.

How windy? (On the Munros)

Southerly 25-35mph, strengthening through the day from west; by afternoon risk 45-50mph over several hours on summits toward west coast.

Effect of wind on you?

Walking becoming arduous, or perhaps difficult locally on/near Skye later. Some sudden strong gusts reaching lower slopes.

How Wet? (Precipitation and its impact)

Dry much of day

Risk of isolated patches of light rain/drizzle on and near Skye, may become more persistent after dark. Otherwise, dry most of daylight.

Cloud on the hills?

Extensive Skye, very little elsewhere

On and near Skye - Banks of cloud from lower slopes up for much of the day, although some breaks may occur for a time. Elsewhere - Some patches of low cloud at dawn will soon clear.

Chance of cloud free Munros?

60%

Sunshine?
Air clarity (below cloud)

Patches of sun, especially across eastern areas. Visibility generally good, but noticeable haze. Will deteriorate further in rain later in the west.

How Cold? (at 900m)

4 to 6C, highest around middle of day.

Freezing Level

Above the summits

Planning Outlook

All mountain areas of Britain from Wednesday 12th December 2018

A battle between cold air to the east and milder air to the west will take place later this week, with confidence low about the general developments into the weekend. It looks increasingly likely that for a couple of days at least, freezing levels will drop markedly, and there is scope for some snowfalls, chiefly on eastern hills. As fronts push northeastwards, there may be a more organised fall of snow into the weekend. Cycles of freeze and thaw are then likely. Winds varied, up to gale force at times, giving severe wind chill.
