Summary for all mountain areas

Cold northerlies continue; significant chill factor over mountains, though speeds less than recent days. All terrain frozen; snow cover widely in Highlands, substantial in north, further showers of snow and hail. Showers continue to feed into N/W Wales. Largely dry with sun and broken cloud N England/S Scotland.

Headline for West Highlands

Cold brisk wind, snow showers north, sunnier south.

How windy? (On the Munros)

Northerly 25-30mph, strongest early morning, some squally gusts all day in showers, shifting northwesterly with time, easing a little inland afternoon, but then tending to increase to 35mph into night.

Effect of the wind on you?

Significant wind chill, severe on high exposed tops where walking conditions will be strenuous with buffeting at times.

How Wet?

Snow showers coasts and Lochaber

Occasional snow showers mostly north Lochaber over Creag Meagaidh/Ben Nevis ranges. Some showers reaching Mull and Islay as well. Extensive snow cover on ground in north. Largely dry Glencoe and southward. Then well into night, persistent snow (or rain to mid-slopes near coast & on islands) moves in from west.

Cloud on the hills?

Varied, often covering northern and coastal tops; clearer south

Varying cloud bases Lochaber and coasts, 700-800m, locally lower in showers. Also often capping tops inland Lochaber above 800-1000m. Well broken or often clear south of Glencoe to Loch Lomond NP/Clyde Sea Lochs.

Chance of cloud free Munros?

40% Lochaber/coasts, to 70% south.

Sunshine and air clarity?

Bursts of sunshine, often sunny Loch Lomond. Visibility excellent away from showers, but in places risk very poor where snow falls or blows around.

How Cold? (at 900m)

-5 or -6C; -8C above 1200m. Wind chill feeling like -17C, to 22C on higher tops, particularly morning.

Freezing Level

Terrain widely frozen; at dawn near -10C some inland glens. Nearest the coast, partial thawing in sunlight to 200-300m, rising slightly further after dark.

How windy? (On the Munros)

Changeable: west-southwesterly 20-30mph, rising with time, up to 40mph over summits, shifting northerly later.

Effect of the wind on you?

Variable conditions, walking increasingly strenuous in exposure with significant wind chill.

How Wet?

Patchy sleet/snow, setting in later

Bands of patchy snow pass eastward, increasingly as sleet/rain to middle slopes near the coast. A broader area of snow arrives afternoon, setting in heavy for several hours inland.

Cloud on the hills?

Becoming extensive

Cloud shrouds the mountains above 800-900m most or all day, variable bases down to 600m during pulses of snow but a few local higher breaks for a time. Filling in more widely to middle or lower slopes with time, first in the north.

Chance of cloud free Munros?

10%

Sunshine and air clarity?

Sunshine unlikely. Moments of very good visibility early, though increasingly appalling as snow sets in with whiteout conditions.

How Cold? (at 900m)

-1 to -3C, some variability, warmest near the coast; trending colder overnight. Feeling as cold as -15C in the wind.

Freezing Level

Terrain widely frozen from overnight, lifting but variable; up to 800m along coasts, unlikely above 300-400m well inland.

How windy? (On the Munros)

Westerly 15 to 30mph, speed likely to vary during day, a lull may develop, then risk increasing south-southwesterly later.

Effect of the wind on you?

Fairly small, but be prepared for marked wind chill on exposed high terrain, risk more blustery in places at times.

How Wet?

Risk snow/rain arrives from west

Rare flurries at first, but largely dry for several hours, but then a risk of more persistent snow developing, moving in from west, near coast turning to rain to mid heights, or above on islands.

Cloud on the hills?

Patchy cloud, risk lowering west

Varied cloud banks in the morning, mainly higher slopes, but some lower mist around glens and mid-slopes inland for a time. If precipitation develops, more extensive cloud lowering over hills.

Chance of cloud free Munros?

40%

Sunshine and air clarity?

High cloud may largely cover the sky, some early brightness, overcast skies becoming duller. Visibility very good whilst dry, risk very poor if snow develops.

How Cold? (at 900m)

-3C, lifting to -1C near west coast, then nearer 0C all areas after dark. Feeling around -10C if exposed to wind.

Freezing Level

Near/below freezing glens upward inland; 500m coast & islands. Tending to rise after dark, but much terrain inland stays frozen.

Planning Outlook

Freezing conditions widely over the mountains all this week - some changes toward the weekend as Atlantic lows try to circulate further northwards, bringing some variable thawing mainly to England and particularly Wales, whilst Scottish mountains may see brief if any periods of above-freezing conditions even onward into mid-month. Complex weather systems later this week, with potentially a deep low moving across southern Britain by Thursday-early Friday which may bring some snowfalls to Wales and the southern Pennines, accompanied by possibly severe gales. More variable wind speeds for Scotland, trending westerly; some lulls but interspersed with gales. Further accumulating upland snow, mixed with some lowland rain.
