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.

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.
