Above the summits
All mountain areas of Britain from Saturday 5th September 2015
High pressure currently located to the west of Britain will push slowly east this weekend to become centred broadly across the country by Sunday and early next week. This will bring several days of fair weather, and very light winds. Daytime temperatures improving slowly. Cloud amounts will vary, but there will be some sunshine. Clear, still nights will result in frost and patchy fog forming in many valleys and glens. Later in the week, the pattern is expected to become south-westerly, bringing an increasing risk of rain and freshening winds for western Scotland.
