Summary for all mountain areas

A damp atmosphere shrouds most west coastal hills in fog to lower slopes in morning. Some breaks forming for England, Wales & eastern Scotland. Rain heavier in middle of the day in western Scotland, spreading later to NW England and N Wales.

Planning Outlook

Low pressure drifts slowly southwards across Britain through Friday into the weekend, followed by improving conditions from the north as pressure builds. Residual areas of rain, drizzle and low cloud may affect Wales, the Pennines and perhaps eastern Scotland through the weekend, whilst west & northwest Scotland become fine and increasingly warm. Most indications favour high pressure influencing Britain into next week, bringing mainly dry and warm weather. Despite some rain this week, most mountain areas will remain very dry underfoot: beware of the risk of fire.
