Planning Outlook

All mountain areas of Britain from Saturday 29th November 2014

This weekend; areas of low or very low cloud, but south from about the Scottish Borders, the mountains may well be above fog and murk. Blustery Scottish Highlands. Temporarily colder with snow showers, mainly W Scotland early next week, after a rain bearing front moves southeast across the country. But for most of the week, rain rare England and Wales, light winds and hills often cloud free. In Scotland, increasingly windy northwards and although frequently dry, rain from time to time, mainly NW Highlands. The expectation over the next 10 days of significant cold weather and snowfall is very low.
