Odd early snow flurries in north Scotland, otherwise clear Munros until late; some snow returns to the west and north Highlands near evening. Little or no rain south Scotland and England, several hours of morning sun and any hill cloud soon clearing. Spotty light rain for Wales, cloud clearing hills, but only glimpses of sun.
Scattered light rain, driest east; cloud above tops afternoon
Easterly 10-15mph in the morning, easing to around 10mph and often less, a slight southeasterly shift as well.
Small.
Patchy light rain, most in the west
Spots of rain drifting around many hills throughout the day, perhaps a lull in the precipitation around the midday hours; risk of patches lingering in westernmost areas, particularly Preseli hills. Rainfall totals likely small.
Varied on high terrain early, mostly east; lifting to clear summits
Some varied cloud around mid to upper slopes in the morning, risk of larger banks northern slopes and particularly Black Mountains. Lifting through morning, likely clearing the summits afternoon and staying clear into evening.

Southerly 10-20mph.
Fairly small.
Showery rain
Rain affecting many hills, the greatest chance in the afternoon when rain may become heavier and more persistent for a few hours.
Rising to the summits
Some varied fog banks in the morning, possibly to lower slopes, these lifting after dawn towards high terrain and becoming well-broken. Cloud caps will linger above 800m where rain occurs, possibly some ragged lower patches too.

Glimpses of sun. Excellent visibility but deteriorating during rain.

Generally east-southeasterly 10-15mph, often less and direction varying.
Mostly small.
Showers, most afternoon
Scattered showers most of the day, dry periods, but a rising risk of more frequent and heavy showers in the afternoon.
Lifting to or off summits, caps during showers
Fog at various heights in the morning, but well-broken below 600m. Lifting through morning to 800m or higher, a chance of summit breaks too, but then a risk of more often capping summits if heavier afternoon showers occur.
70%
Glimpses of sun. Variable visibility, very good during drier periods, may be very poor if heavier showers occur.
6C rising to 11C.
Above the summits.
Low pressure to the north of Scotland brings stronger wind and a greater risk of showery rain from Thursday. Cooler temperatures, high Munros staying below freezing for several days, the freezing level as low as 800-1000m. Showers affecting England and Wales, always a risk of heavier bursts afternoon, but timing and location of showers uncertain. Early varied cloud tends to lift to higher slopes, often above summits but some tops shrouded for longer. Into the weekend, low pressure south of the British Isles, facilitating a strong easterly wind with increasingly heavy rain and showers for Wales and southern Pennines. Pressure may remain higher in Scotland for a few days, but staying cold here with freezing levels perhaps to 700m. Indications of increasingly widespread unsettled weather into next week.
