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 West Highlands

Risk snow, whiteout and strengthening upland gales.

How windy? (On the Munros)

Complex situation - speeds may change quickly: West to southwesterly, locally below 20mph for a time Lochaber, but threat often widely 40-50mph, and likely to strengthen through day.

Effect of wind on you?

Locally at times small, but prepare for rapidly deteriorating conditions setting in, with blowing snow and severe wind chill.

How Wet? (Precipitation and its impact)

Risk snow setting in

Some uncertainty of detail: A likelihood of periods of constant snow, may set in widely, giving sustained whiteout. Some areas may escape more often dry, or only see occasional flurries.

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?

20%

Sunshine?
Air clarity (below cloud)

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

How Cold? (at 900m)

-3C. In strongest wind on highest tops, wind chill feeling colder than -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.
