Summary for all mountain areas

A complex area of low pressure to the north and west of Scotland brings a risk of snow setting in for periods for the W/NW Highlands. Smaller amounts of snow toward east. Frequent snow also for western hills of England & Wales. Widespread upland gales and severe wind chill, expect perhaps N Scotland.

Headline for The Northwest Highlands

Risk locally persistent snow. Winds may reach gale force.

How windy? (On the Munros)

Complex situation - speeds may vary marked locally and through the day: West to southwesterly, in range 20 to 40mph, perhaps local lulls.

Effect of wind on you?

At times small, but be aware of a potential deterioration, resulting in significant wind chill and difficult conditions in blowing snow.

How Wet? (Precipitation and its impact)

Risk snow setting in west

Some uncertainty of detail: A risk of periods of constant snow, focused on western mountains - threat setting in giving sustained whiteout. Areas across Sutherland escaping more often dry.

Cloud on the hills?

Fairly extensive higher tops

Banks of cloud across higher slopes, at times forming to lower levels, mostly around snow and across west coastal hills.

Chance of cloud free Munros?


Air clarity (below cloud)

Limited if any sun. Visibility appalling in snow and low cloud, but in places often very good.

How Cold? (at 900m)

-3C. In strongest wind on higher terrain, wind chill feeling close to -20C.

Freezing Level

Most mountain terrain frozen and snow covered from lower slopes up; or above 400-500m coastal hills.

Planning Outlook

All mountain areas of Britain from Sunday 15th December 2019

Staying cold through into early next week. Most mountain terrain frozen, to lower slopes in Scotland. Some substantial snowfalls, with snow lying from many lower slopes up away from immediate coasts. Most precipitation focused on western mountains. Winds very varied, sometimes gale force, but also some lulls. Quieter conditions briefly early next week. A gradual but complex rise of freezing level from the south through midweek, although Scottish mountains may well stay substantially frozen. Rain preceded by snow extending in from the southwest.
