Planning Outlook

All mountain areas of Britain from Tuesday 1st September 2015

High pressure will dominate the weather over the coming week, possibly two weeks. But this week, its position, just west of Britain will ensure persistent cold conditions in northerly winds, bringing frost to some valleys at night, and highest Scottish summits close to freezing point. It will become substantially dry, but frequently cloudy although away from N Scotland. Most of the cloud will be above the summits. Frequently superb visibility.
