Planning Outlook

All mountain areas of Britain from Monday 6th July 2015

Several days of cooler fresher conditions mainly over Scotland. On Monday a large area of rain, some of it heavy particularly northern England and southern Scotland, is likely to move across all mountain ranges from the southwest. A slow improvement likely as showers on subsequent days become increasingly confined to the north and east of Scotland. As temperatures fall appreciably midweek these showers will turn to snow over highest tops in Scotland where night temperatures may dip just below freezing. However, milder, wetter conditions should soon return.
