Planning Outlook

All mountain areas of Britain from Saturday 16th December 2017

Snow melt will be substantial from Sunday, although from Wednesday there will be a series of freeze thaw cycles on the Scottish Highlands. Rain (occasionally snow higher summits) intermittently W & NW Scotland, but elsewhere total rainfall small. Most forecasts indicate frequent stormy, often wet conditions from Christmas as a series of deep Atlantic lows come in. Intermittently snow will fall, particularly Scottish Highlands. However, a small minority of indicators suggest much colder, drier conditions eventually returning.
