Summary for all mountain areas

A slow-moving front from the west brings rain and low cloud to western Scotland, turning to snow on tops as colder air arrives; freezing level later below 800m. Patchy rain encroaching further into Cumbria with time. Some heavier thundery bursts possible in Wales. Strong southerlies ease and turn W-NW'ly.

Headline for West Highlands

Rain and wind; easing, but turning colder

How windy? (On the Munros)

Gusty south-southwesterly 35-45mph. A sudden easing with a westerly shift along the coast in the morning, 25-35mph, settling northwesterly through afternoon; strongest wind south.

Effect of the wind on you?

Arduous walking early in the day with significant wind chill; an easing trend, may be fairly small for a period, but wind remains a nuisance on high terrain.

How Wet?

Often raining, turning to snow on high terrain; easing trend later

Rain soon widespread, perhaps just light drizzle in the south early. A heavier band will pass east, followed by just drizzle; rain turns to snow on the tops, the snowfall level lowering. A breaking trend from the west later.

Cloud on the hills?

Extensive, may improve late in day

Cloud soon shrouds nearly all terrain from at least the middle slopes upward. Some variability as rain comes and goes, and may begin to break somewhat along the west coast late in the day (remaining cloud banks below summits).

Chance of cloud free Munros?

10% rising to 40% west coast

Sunshine and air clarity?

Sunshine unlikely until late in the day. Substantially poor visibility.

How Cold? (at 900m)

3 or 4C from dawn, soon beginning to lower from west, -1 or -2C afternoon into evening. Feeling like -7 to -10C in the wind.

Freezing Level

Just touching the summits at dawn, lowering as rain passes, 600-700m evening, frosts forming in sheltered lower terrain overnight.

How windy? (On the Munros)

Southerly 15 to 25mph, but risk gusty 30mph in places around higher mountains, greater risk toward Mull.

Effect of the wind on you?

Fairly small, but locally gusty spots may be more uncomfortable.

How Wet?

Precipitation unlikely

Cloud on the hills?

Mostly little if any

Local patches around some south-facing slopes for a time, mostly lifting above 700-800m, may linger a for a time near Arran.

Chance of cloud free Munros?

70%

Sunshine and air clarity?

Mostly sunny Visibility excellent.

How Cold? (at 900m)

4C, but some lower slopes colder in the morning; small change with added height.

Freezing Level

Slight frost some glens and sheltered higher areas after dawn, but lifting above freezing to the tops.

Planning Outlook

Higher pressure extends back across the country to bring dry conditions on Saturday, feeling mild in sunshine by day after a chilly start. More cloud by Sunday as weak fronts encroach in from the west, some drizzly rain moving into western Scotland. Patchy rain likely in the west at least early in the new week, likely dropping back just below freezing on the Munros for a time with some snowfall on higher areas. Winds fairly light early week, then a risk of strengthening southwesterlies later in the week; changeable weather conditions with spells of rain coming in from the Atlantic. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, only very patchy snow remains around highest tops in England and Wales.
