Planning Outlook

All mountain areas of Britain from Thursday 21st August 2014

Remaining cold on the mountains - and also at night in many valleys with ground frost some nights - until Sunday. The air very clear and many summits free of cloud during the day; although there will continue to be showers - these dying out through the weekend. Rain and areas of low cloud will come in early next week as an Atlantic low approaches and then crosses Britain.
