Summary for all mountain areas

There may be a lull in generally 'poor' conditions near the axis of an elongated low. But expect widespread strong to gale force upland winds, areas of constant (or near constant) precipitation, falling as snow on higher areas, giving whiteout on mainly the W & N Scottish Highlands.

Headline for West Highlands

Upland gales developing; widespread snow; freezing level dropping.

How windy? (On the Munros)

Confidence low due to close proximity of a deep low: a lull, perhaps lasting into the afternoon well inland, will give way as northwesterlies, in range 30 to perhaps 50mph develop.

Effect of wind on you?

Expect walking to become difficult, together with significant wind chill, across the hills from the west.

How Wet?

Rain or snow most of day; heaviest coastal mountains

Precipitation, most constant and heavy coastal mountains most of daylight. Snow above 550m to 900m, lowest afternoon from south. Periods of little precipitation central highlands and Loch Lomond NP east of A82. Whiteout; widespread coastal mountains.

Cloud on the hills?

Extensive across the mountains

Widespread cloud across the hills all day. Some breaks to 900m well inland and perhaps 1050m east of the West Highland Line south of Loch Treig. But cloud extensively at or below 500m, and sometimes lower coastal hills.

Chance of cloud free Munros?

Less than 10%; but 20% eastern Loch Lomond NP

Sunshine and air clarity?

Rare if any sun, except occasionally Loch Lomond NP. Fog across the hills; visibility appalling or near zero where in cloud and snow.

How Cold? (at 900m)

0 to -2C; will at times feel as cold as minus 16 Celsius directly in the wind.

Freezing Level

Around 1000m morning, dropping to 700m from west.

Planning Outlook

All mountain areas of Britain from Thursday 7th May 2015

One or two fine days with light winds on the mountains to come over the next week, but overall conditions will change day by day. There will still be one or two very cold days (low freezing level) across the Scottish Highlands, and there will be areas of rain, some very slow moving, and occasionally snow higher Scottish areas.
