A broad and very slack area of low pressure will edge north bringing extensive low cloud and areas of drizzle, with again bursts of heavy, perhaps locally thundery rain, developing into Scotland. Best breaks in cloud and sun in the northwest Highlands, and clearer, brighter conditions developing for southern Wales.
Low cloud local drizzle east. Sunnier in west. Heavy showers may develop. Gusty.
Easterly 20-30mph, in morning, gusty around major summits. Will ease and become more variable from south in afternoon.
Blustery in morning which may affect comfortable walking on tops mostly in north. Small into afternoon.
Local drizzle, risk heavy showers forming.
Drizzly if in hill fog, mainly toward east. Many western areas often dry, but risk isolated bursts of rain forming. During the afternoon, greater risk of scattered heavy and possibly thundery bursts developing.
Most persistent low cloud in east
Blanket fog from lower elevations upward in eastern areas. Some hill slopes inland may be between cloud layers for periods. Breaks better westwards toward Skye, some western hills often clearer all day.
20% east to 60% west.
Sun mainly near west coast, but weak through high level cloud. General slight haze, but murkier eastern areas.
7C in east Ben Wyvis to Ben Hope, up to 10C near west coast and on Skye.

Slow-moving weather patterns continue through the Bank Holiday weekend as a weak zone of low pressure dominates over the British Isles. There will remain uncertainty of local day-to-day detail, but most likely the wind often light and temperatures generally mild, but less warm than midweek in western Scotland. Sunday into Monday, will see varied zones of heavy showers forming, local thunderstorms, but some places escaping often dry with the best sunny breaks for coastal areas as the convection builds inland. High pressure then tends to build from the west into midweek to bring a fair amount of dry weather, although rain bearing fronts may return to the northwest at times.
