Becoming negligible.

How Wet?

A few showers; dying out

Starting showery, particularly Lochaber. Showers will become confined to Lochaber and by about midday more or less all die out.

Cloud on the hills?

Becoming confined to higher slopes, later may well almost all clear

Progressively improving as extensive cloud above 700m Lochaber and more patchy above 900m elsewhere gradually rises. By mid afternoon, perhaps still fragments some higher tops; but the hills mostly cloud free.

Chance of cloud free Munros?

30% gradually rising to 90%

How windy? (On the Munros)

Easterly 10-15mph; strengthening to around 25mph; very gusty in places.

Effect of the wind on you?

Mostly fairly small, but expect sudden gusts to develop (sometimes on lower slopes) making balance tricky.

How Wet?

Deteriorating: rain increasingly likely

Low confidence - timing of changes very uncertain: As cloud thickens from south, rain will probably spread northwards, and become widespread and constant.

Cloud on the hills?

Increasingly forming in rain

Most, possibly all hills cloud free morning, possibly for most of day. In rain, fog will gradually shroud some or most higher slopes, even extending to some lower slopes, particularly Loch Lomond NP and Arran.

Chance of cloud free Munros?

80% dropping to 30%

Sunshine and air clarity?

Little or no sunshine - although there may be some weak sunshine through thin high cloud. Excellent or superb visibility, but dropping markedly in rain.

How Cold? (at 900m)

9C

Freezing Level

Above the summits.

Planning Outlook

Still a few showers W & NW Highlands on Sunday, and threat of some rain by dusk western mountains. The rain will be ahead of a very complicated weather pattern early next week; areas of rain will drift slowly across central and mainly northern Britain, but the distribution of rain (and associated low cloud) remains very uncertain. Despite some recent rain (mainly in Scotland), away from the W & NW Highlands terrain remains exceptionally dry: 'tinder dry'.
