Planning Outlook

All mountain areas of Britain from Wednesday 14th November 2018

Very wet underfoot on western mountains through midweek with localised flooding possible in south-west Scotland, the Lakes & west Wales. Residual rain will linger in western Scotland into Thursday, and areas of very low cloud will persist. High pressure to the east will then dominate into the weekend and beyond, resulting in a sustained period of dry weather for most mountains, with winds from the east or south-east. After a mild spell, temperatures are expected to lower next week. Low level fog common, and banks of low cloud at times coming in from the North Sea. Sunshine best in the west.
