All mountain areas of Britain from Saturday 23rd August 2014
Until Sunday night, cold on the mountains - and also at night in many valleys with ground frost some nights. The air very clear and many summits free of cloud; although there will be showers - these dying out through the weekend when the wind will gradually drop away. Rain and areas of low cloud will come in on Monday as an Atlantic low approaches and then crosses Britain. However, the rain may largely miss the NW Highlands. Through the week, generally unsettled, with further rain from time to time.
