Summary for all mountain areas

A blustery, gusty morning in northern England and Scotland, gales for a time in northwest Scotland, tending to ease. Patchy rain from central Scotland down the spine of the Pennines eases into drizzle over the high tops, drizzle in east Wales too with extensive hill fog in these areas. Best of breaks west Wales and NW Highlands.

Headline for West Highlands

Windy, risk gales early, easing; patchy rain and hill fog

How windy? (On the Munros)

Southeasterly 35-40mph from dawn; strong gusts over tops and downslope, may reach 45mph, risk higher Mull/Lochaber early in the day. Easing as the day goes, 20-30mph by dusk.

Effect of the wind on you?

Blustery, turbulent airflow with sudden strong gusts running downslope and reversals in direction; expect considerable buffeting, stability challenges, and wind chill. Conditions improving with time.

How Wet?

Patchy rain and summit snow

Rain arrives onto the southern islands around dawn and drifts over the Clyde sea loch and towards Loch Lomond/Glencoe; falling as snow on high ground. Patchier rain drifts up towards Mull/Lochaber too. Largely dry east Lochaber/Creag Meagaidh area.

Cloud on the hills?

Most extensive south, best breaks northwest coast

Cloud often shrouding the high terrain of central and southern Highlands, some higher breaks for a time but will tend to lower as rain arrives, bases down to 600-700m. Higher bases with some breaks are likely west of Loch Linnhe. Will fill in more extensively into night.

Chance of cloud free Munros?

30% south, up to 60% coastal Lochaber

Sunshine and air clarity?

A little weak sun perhaps toward northwest coast. Otherwise cloudy. Visibility good, but poor in any rain or snow.

How Cold? (at 900m)

1 or 2C, some slopes reaching 3C near Glencoe/Loch Lomond. Feeling closer to -10C in the wind.

Freezing Level

Around 1000m, some local frosts in glens inland at dawn. Lifting, rising above the summits by dusk.

How windy? (On the Munros)

Southeasterly 30 to 40mph; gusty over the tops and downslope, strongest may reach 45mph.

Effect of the wind on you?

Fairly arduous conditions for several hours, sudden and strong gusts will challenge balance. Significant wind chill.

How Wet?

Morning rain, then drizzle south/west

Widespread rain before dawn lingers through morning, some local breaks inland Lochaber. Largely clearing to the northeast, but drizzly rain continues around the southern islands/Glencoe.

Cloud on the hills?

Fairly extensive, but breaks west coast

Fairly extensive banks at varying heights in rain. As rain clears, very disorganised cloud banks, ragged patches clinging to forest canopies for a time, best chance of clear hills coastal Lochaber.

Chance of cloud free Munros?

32%, rising to 50% northwest areas

Sunshine and air clarity?

Mainly overcast. Early rain and an increasing haze will limit visibility through the day.

How Cold? (at 900m)

3 or 4C, but feeling closer to -10C where exposed to the strongest winds.

West-southwesterly 10-20mph, may shift northerly afternoon.

Effect of the wind on you?

Fairly small.

How Wet?

Rain on and off

Periods of patchy rain for most mountains, likely more frequent on hills nearest the west coast.

Cloud on the hills?

Shrouding the tops with variable lower bases

Fairly extensive over all high terrain, lower bases during rain, down to 400-600m near the coast much of the day, particularly Lochaber; some fog in the glens as well early in the day.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Mostly cloudy. Good visibility but variable as rain comes and goes.

How Cold? (at 900m)

2 or 3C

Freezing Level

Above the summits, lowering to 1100m afternoon.

Planning Outlook

Cloud and patchy rain lingers for a few more days early next week, then a slow change to drier and chiller weather into the Christmas period as high pressure builds to the north. Easterly winds will be dominant, the strongest winds in England and Wales. Cloud may be fairly sheet-like in the east sometimes, though variably more extensive or broken. The coldest air will reach England and Wales on the easterly wind with freezing levels reaching as low as 400-600m in Wales, staying slightly warmer in northern Scotland with freezing levels nearer the high summits for a time under the core of high pressure.
