Planning Outlook
Overall little change in conditions over the coming week: the mountains extensively foggy, precipitation from time to time (again concentrated on eastern Scotland and southern and eastern Wales) and often strong southeast or easterly wind. However, a slight rise in temperature will result in thawing of lying snow from southern Scotland southwards and some thawing up to around 900, sometimes 1050m Scottish Highlands - although the return of low freezing level toward the middle of next week.
