Many mountains dry; warm sunshine in the west. Low risk of isolated thundery showers forming. Greater threat of thunderstorms mid & south Wales. Fog persists in eastern Scotland and England from low levels upward; just some highest tops above this layer.
Likely dry, fog breaking up. Mostly light winds.
Direction varied; 10mph or less although near central belt, particularly Arran northeasterly 15 or 20mph.
Mostly negligible
Rain very unlikely
Remote risk of isolated bursts of rain or possibly an isolated thunderstorm western mountains afternoon.
Very little by late morning
Ribbons of fog from some valleys up after dawn, in some areas extensive, particularly central highlands and perhaps across Loch Lomond NP. Nevertheless, some summits cloud free (in places above the fog). The cloud will all or nearly all clear by mid or late morning.
70%
Banks of cloud will tend to break up to give sunshine. Haze very likely lifting to give excellent, possibly higher up superb visibility.
11C from dawn, rising to 17C.

80%
Patches of sun, may break through widely western mountains. Areas of mist or haze may linger, but visibility may well become excellent.
Up to 17C locally in west, but around cloud banks nearer 10C.

Remaining warm and humid through the weekend, particularly in western regions, whilst eastern areas are cooler under North Sea air, which brings a risk of lingering fog banks. The Scottish Highlands stay extensively dry. Thundery rain mostly confined to Wales, although rain may expand back northwards into the Pennines by Sunday. Into next week, light winds and areas of slow-moving showers at first, then a gradual change is likely as windier conditions move in from the Atlantic, with belts of rain or showers.
