Showers soon drifting into northwest Scotland, cloud spreading onto western high terrain, and rain later more widespread across northern Scotland. Scattered showers in southern Scotland and afternoon in England, early low cloud but many summits clearing. Some showers in Wales, mostly south with heavy bursts afternoon.
Mild, cloud lifting to high terrain; showery, locally heavy later
North-northeasterly 5-15mph, trending towards the higher end of the range with time.
Small, but some nuisance breezes may form on high summits later.
Showers, locally heavy afternoon
A band of showery rain affects most hills from dawn, perhaps well into the morning. An easing trend from midday, just scattered showers afternoon, but the showers may increase in frequency again later afternoon, a risk of some heavy bursts.
Extensive early, lifting to high terrain afternoon with breaks
Cloud widespread from dawn, likely to middle slopes, to lower south slopes. Bases begin to rise through morning, mostly above 700-800m afternoon and likely with breaks off summits for a time. Where showers turn heavy, bases return to 700m or lower, and some ragged lower patches on southern slopes after rain.
20% rising to 80%
Mostly cloudy, but a few glimpses of sun breaking out here and there afternoon. Variable visibility, often very good, but deteriorating during showers.
6 to 9C, mildest in the east. Westernmost Brecon Beacons and Preseli may only reach 7C.

East turning southeasterly, 15 to 20mph, some gustier spots 25mph.
Fairly small, but feeling noticeably chillier if exposed to wind on higher tops.
Local showers
Risk of a little patchy light rain from time to time during the day. Scattered showers more likely in afternoon, greater risk in west, but some places stay largely dry.
Covering some slopes at times, lifting
Some varied cloud around mid to upper slopes in the morning, larger banks if any rain occurs. Much cloud lifting to the tops and breaking above into afternoon, but some ragged patches return in showers.

A little sun, perhaps often a rather cloudy sky. Visibility excellent.
4C, rising to 7C afternoon.

Chilly most or all week, particularly across the Scottish Highlands where fresh snow in some areas and morning freezing level sometimes below 700m; patchy frosts developing in the glens and corries, though always thawing soon after sunrise. Wednesday is likely the chilliest day. Mixed weather with showers drifting around the country, though total rainfall will be fairly small. Wind often light as well, though variable afternoon breezes will form, particularly around showers where gusts may be suddenly strong. Local low fog in the mornings, typically lifting towards high terrain, often above summits though regions for best breaks are uncertain; often cloud with just glimpses of sun for most. Next weekend is indicated to be wet in Wales and England; detail remains uncertain in Scotland.
