Summary for all mountain areas

Warm and fairly humid southerly winds will bring a few bursts of thundery rain northwards - ahead of more widespread thunderstorms reaching Wales in the evening and most other areas through the night. Some of the rain will be heavy.

Headline for Cairngorms NP and Monadhliath

Gusty winds; scattered bursts rain, chance thunder. Warm.

How windy? (On the Munros)

Southerly, speed fluctuating both in time and between adjacent slopes. Typically 25 to locally a very gusty 40mph morning. Will gradually ease afternoon and evening.

Effect of the wind on you?

Expect variable conditions, sudden gusts even on lower slopes may well make balance difficult. Fairly small later in day.

How Wet?

A few bursts of rain; small risk lightning

A few showers, possibly the odd heavy thundery burst. In morning, perhaps patches drizzly rain east from Ben Alder to summits immediately north of Glen Garry.

Cloud on the hills?

Gradually clearing most summits: most persistent more southern hills

Varied conditions from dawn; cloud sometimes forming lower slopes perhaps widely on summits immediately north of Glen Garry where even in afternoon perhaps cloud base only 600m. Elsewhere, by early afternoon, cloud nearly all above 900 to 1100m - may all clear.

Chance of cloud free Munros?

30% morning; in afternoon 70% Cairngorms and Monadhliath

Sunshine and air clarity?

Sunshine increasingly coming through and visibility mostly excellent by midday.

How Cold? (at 900m)

How windy? (On the Munros)

East later southerly 10mph, perhaps 20mph for a few hours morning. Sudden gusts 40mph possible.

Effect of the wind on you?

Mostly small, but gusts, mainly near thunderstorms, perhaps sudden, could well unbalance you.

How Wet?

Periods of thundery rain

Detail uncertain: Areas of thundery rain will move northwards, easing afternoon to scattered (perhaps still thundery) showers. Total rainfall very varied, in places within a few miles.

Cloud on the hills?

Generally very extensive, although some breaks to the tops near the coast

Frequently or persistently foggy higher slopes, and particularly morning fog sometimes from just above the valleys upward. Will improve at times, perhaps extensively later in day when breaks possible toward or above 900m.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Cloudy or dull and misty much of the day, particularly away from western summits.

How Cold? (at 900m)

How windy? (On the Munros)

Westerly, varying between 15 and 25mph.

Effect of the wind on you?

Fairly small

How Wet?

Little or no rain

Drizzly rain possible here and there - but the day substantially dry.

Cloud on the hills?

Unlikely to lift above higher summits all day

Cloud base will tend to rise, by afternoon mostly 750 to 900m west of A9 and 1000 to 1200m further east - with the highest chance of cloud free summits being those accessible from Deeside.

Chance of cloud free Munros?

10%, but 60% Deeside afternoon

Sunshine and air clarity?

Patches of sun, particularly Deeside. Very good visibility.

How Cold? (at 900m)

11C

Freezing Level

Above the summits.

Planning Outlook

Colder air from the west will reach all areas by Sunday. However, low cloud probably very extensive on western mountains, together with drizzly showers. Most of next week will be dry and increasingly warm, but western Scotland will still have occasional rain as weakening fronts affect particularly coastal mountains. By mid week it should be fine everywhere - although it may not last through the following weekend.
