Very warm or hot by afternoon and very high humidity - anticipate dehydration and possible sunburn. Scattered thunderstorms will drift about slowly, mainly England and Wales, bringing locally torrential rain.
Areas of thundery rain soon clearing. Very warm with hazy sunshine.
Winds varying in direction, 10mph or less.
Negligible.
Rain unlikely by mid morning
Overnight thunderstorms will by dawn have largely cleared northwards. Then very likely dry although toward Great Glen, small risk isolated bursts of rain and perhaps thunder in afternoon.
Extensive after dawn. Will improve: most summits will clear.
After dawn: very varied; some areas foggy from lower slopes or glens up whilst in others fog higher up, and some summits between cloud layers. Will progressively improve as most higher summits clear, although in places patches above 750m to in afternoon 900m. However coastal slopes may have banks of fog from lower slopes up on and off all day.
20% rising to 80% by early afternoon
Patchwork of hazy sunshine after a widely dull and misty start. Visibility improving although a haze most or all day.
15C.
Above the summits.

Direction likely to vary 10mph or less. Near the coast, mostly northerly, up to 20mph - not necessarily on higher slopes.
Mostly negligible
Rain not expected
Clearing nearly all summits
Cloud extensive from dawn, forming many lower slopes up, although toward the west coast south from Wester Ross, only patches on higher tops - where by late morning, most summits cloud free. Elsewhere the improvement slower: most or all summits cloud free by mid afternoon.
70%
Cloud breaking, particularly western mountains to give patches of sun. Probably haze, although perhaps excellent visibility northern mountains.
Varied, as low as 7C where in cloud, but up to 13C near west coast in afternoon.
Above the summits.

Direction varied; 10mph or less.
Negligible
Rain not expected
Very little by late morning
Ribbons of fog from valleys up after dawn, in some areas extensive. Nevertheless, some summits cloud free (in places above the fog). The cloud will all or nearly all clear by mid or late morning, but may leave patches on higher tops near the coast.
70%
Banks of cloud will tend to break up to give sunshine. Far north may be most cloudy. Haze very likely lifting to give excellent or superb visibility.
10C, rising away from far north to 17C.
Above the summits.
Remaining warm and particularly England and Wales humid. However, thundery rain will become mostly confined to Wales, whilst the Scottish Highlands are extensively dry. Overall extensive sunshine, although banks of very low cloud, mainly more eastern mountains, including those in east Wales. A change to wetter and gradually less warm conditions across Britain is likely early next week.
