Summary for all mountain areas

Windy. Low cloud and patches of rain will clear southward across Wales. Otherwise, a drop in freezing level will bring snow showers to Scotland (mainly west and north), and bursts of sun. Although a rise in cloud base, most western mountains will remain shrouded in cloud.

Headline for West Highlands

Upland gales or near gales. Snow showers, mainly Lochaber.

How windy? (On the Munros)

Northwesterly 35mph, although post dawn and then through the day at times on highest summits, nearer 45mph.

Effect of the wind on you?

Walking widely arduous, and for periods, particularly on higher summits difficult. Significant wind chill.

How Wet?

Occasional snow showers, mainly toward north

Occasional hail and snow showers, rain generally below 600m. In Lochaber and Mull in morning, the precipitation may be frequent. Few showers will reach southern and eastern Loch Lomond NP and Arran.

Cloud on the hills?

Almost constantly covering higher areas

Cloud base fluctuating, typically between 500 and 750m, although a few breaks higher up, mostly central highlands, where by afternoon cloud rarely below 900m.

Chance of cloud free Munros?

10% Lochaber to in afternoon 30% central highlands and near Loch Lomond

Sunshine and air clarity?

Mostly cloudy, bursts of sun mostly well inland and Arran. Visibility very good, but very poor in precipitation.

How Cold? (at 900m)

0 or -1C. Will feel as cold as minus 13C directly in the wind.

How windy? (On the Munros)

Upland gales and gusty. North westerly 40 to 50mph, at first will ease a little later in the day.

Effect of the wind on you?

Difficult and serious walking conditions where exposed to wind. Gusts may throw you off balance.

How Wet?

Persistent rain in morning

Persistent rain at first will clear, although timing uncertain. Showers following, soon of hail or snow to 450m. Will become showery once the front clears, the timing of which is uncertain.

Cloud on the hills?

Low cloud, rising a little

Low cloud in the morning will rise as the front moves south and clears. Cloud base will then vary quickly: dropping below 600m near showers, but breaks to 900, perhaps 1100m southern and eastern Loch Lomond NP.

Chance of cloud free Munros?

30%

Sunshine and air clarity?

Dull at first but then bursts of sun, and visibility intermittently very good.

How Cold? (at 900m)

4C dropping to -2C

Freezing Level

Above the summits at first but dropping to 700m behind the front.

Planning Outlook

Westerly winds, sometimes exceeding gale force at least in Scotland will continue until into next month. There will be frequent rainfall on western mountains; copious on the W & NW Highlands, where as temperatures oscillate, there will be both rain and snow - over time, the snow accumulation on the Munros. Further south, only occasionally will freezing levels be low, with most precipitation as rain. There remains uncertainty later Sunday (30th) when a small low may bring significant snow to the Scottish Highlands.
