Planning Outlook
West to southwesterly upland gales will ease briefly into Boxing Day as high pressure expands northwards. Mild for all through midweek; little if any remaining lying snow on the mountains. Damp with extensive very low cloud, some steadier rain western Scotland; higher cloud bases and brighter further east. Southwesterlies strengthening again into Friday and the weekend, particularly Scotland where gale force again for periods over the mountains; rain remaining frequent over western Scotland, occasionally snow only on highest tops. Into New Year period, likely generally unsettled with areas of low pressure bringing risk of more widespread precipitation - indications favour colder conditions with upland snow.
