Planning Outlook
More cloud by Sunday as weak fronts encroach in from the west, some drizzly rain moving into parts of Scotland, hazy elsewhere. Patchy rain likely in the west at least early in the new week, likely dropping back just below freezing on the Munros for a time with some snowfall on higher areas. Winds fairly light early week, then a risk of strengthening southwesterly later in the week; changeable weather conditions with spells of rain coming in from the Atlantic. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, only very patchy snow remains around highest tops in England and Wales.
