Overnight thunderstorms will have cleared by dawn. Then dry much of region, although in afternoon risk scattered thunderstorms, most likely Perthshire.
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 above low cloud. Will progressively improve as most higher summits clear. Banks of fog likely to return temporarily in and after rain.

Mostly negligible
Rain unlikely
Low risk isolated pockets of rain or drizzle.
Extensive, before clearing many tops
Cloud extensive from dawn, forming many lower slopes up, although west of A9, most cloud above 700m before lifting to clear summits by about midday. Elsewhere the improvement slower, clearing most or all summits afternoon (in places above lower cloud).

Direction varied; 10mph or less although near central belt, particularly Ochils northeasterly 15 or perhaps 20mph.
Mostly negligible
Rain very unlikely
Small risk of a few bursts of rain near central belt.
Probably very little by late morning
Areas of fog from valleys up after dawn, perhaps extensive Angus and Ochils. Nevertheless, some summits cloud free (in places above the fog). Most cloud will clear, although may leave patches below about 900m.
60%
Banks of cloud will tend to break up to give sunshine (in some areas perhaps above lower cloud). Haze may persist in some areas, but particularly higher up visibility excellent or superb.
10C at first and in cloud, rising as high as 17C by afternoon.
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.
