Planning Outlook
Rain at some stage more or less daily on most mountain areas through the coming week. However, total rainfall small, and frequently dry E & S Wales and S Pennines. Frequently windy Scottish Highlands, whilst progressively southwards, periods of strong winds will less frequent. A brief period of colder weather around the middle of next week will bring snowfall to some northern mountains.
