Varying quickly over high terrain
Cloud frequently changing over tops, often capping windward higher slopes in the west and north above 800-900m, ragged patches to 600m in showers; occasionally breaking above higher slopes.
Chance of cloud free Munros?
30%

Planning Outlook
Staying notably chilly for mid-May through this week as air from the north-northwest prevails, with showers heavy at times and containing hail with snow over the tops, but over the weekend a front will edge in and bring a change to westerly winds. Next week may see ridging across England and Wales giving drier conditions, but occasional rain and blustery south-westerly winds for Scotland.
