Planning Outlook

All mountain areas of Britain from Saturday 31st January 2015

Cold throughout the coming week. Snow showers, focussed on mountain areas with the sea to the north will continue into next week, but over next week as a whole, there will be substantial fine conditions. Upland winds, still gale force intermittently into next week will then ease. Most terrain will remain frozen most or all next week, but otherwise, weather conditions will become fairly benign.
