Planning Outlook
East to southeasterlies continue through the weekend and onward into next week, frequently strong to gale-force over the mountains, giving severe chill factor. Below freezing across high terrain in Scotland, and into early next week a lowering freezing level over hills in England and Wales. Frequent or persistent snowfall over east and southern Scottish mountains, rain on lower slopes causing flooding in the short term. Patchier and small amounts reaching coastal regions in west-northwest Scotland. Areas of rain and increasingly hill snow push across England and Wales as low pressure remains dominant. Low cloud often covering many hills.
