Planning Outlook

All mountain areas of Britain from Friday 6th March 2015

A change in weather pattern will bring extensive south or southwesterly winds to all mountain areas. There will be sustained thaw of lying snow - particularly into this weekend, leading to considerable snow loss across the Scottish Highlands. There will be extensive low cloud and rain focussed on western mountains over the next few days, although this may well clear the Scottish Highlands on Sunday. Through next week, rain bearing fronts will move slowly eastwards from time to time, but overall substantial fine weather.
