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.
Extensive low cloud and drizzly. Some heavy showers may break out.
Risk occasionally gusty easterly 20-25mph early in the day, otherwise often variable and low speeds 10-15mph or less.
Mostly small, but risk of suddenly gusty locations on some slopes early in the day.
Drizzle/local rain, risk heavy showers forming.
Drizzly in hill fog. Risk localised bursts of rain forming almost anywhere. During the afternoon, greater risk of scattered heavy and possibly thundery bursts developing, mostly in the west.
Extensive low cloud
Blanket fog from mid-slopes upward much of the region, to some lower slopes in east. Highest cloud bases toward Lochs Tay and Rannoch, but shrouding many hills all day.
10%
Little if any weak sun. Hazy, risk widely murky.
6 or 7C.

Under a very slack cyclonic pattern, winds will vary markedly 5-10mph, at times calm. In and around showers, risk 25mph.
Small to negligible often through the day. Risk of sudden gusts within the vicinity of any heavy showers.
Drizzle, developing to heavy showers.
Pockets of drizzle and patchy rain from dawn here and there. Within an unstable environment, will develop into heavy showers with the risk of thunderstorms.
Extensive, local breaks as bases slowly rise.
Within a humid environment, expect extensive hill fog through the day. Lowest bases in morning, before slow rise as convection builds, with local breaks.
20%
Little or no sun. Hazy, and for periods in the morning murky.
6 to 8C, warmest towards and into afternoon.

Winds remaining slack and variable, 5 to 10mph or a times calm. Scope however, for sudden gusts of 25mph.
Small, but scope for local sudden gusts of in and around any heavy, perhaps thundery, showers.
Patchy rain, then thundery showers.
Patches of rain here and there in morning, but some areas dry. Will break up into heavy downpours and scattered thunderstorms into the afternoon.
Extensive, some local breaks
Low cloud very likely widespread from dawn with banks from lower slopes. Slow rise in base, will allow some breaks, but these filling in again in the downpours.
30%
Mostly overcast with rare glimpses of sun. Hazy, with rather murky conditions, may improve to become good at times, away from rain when visibility will be poor.

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.
