Planning Outlook
East to southeasterlies continue 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. 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.
