Summary for all mountain areas
A band of rain over central Scotland in the morning sweeps into England and Wales; some heavy bursts with extensive cloud. Rain eases afternoon, to patches over Wales and the Peak District. Drizzle and light rain follows in west Scotland, little reaching eastward where high cloud breaks form.
Headline for Brecon Beacons
Light rain arrives, varied hill cloud from dawn tends to lift
How windy? (On the summits)
Westerly 10-15mph. Later, shifting northwesterly and strengthening somewhat, further strengthening overnight.
Effect of the wind on you?
Small, though a notable breeze will pick up late in the day, particularly western hills.
How Wet?
A little light rain
Some spotty light rain drifts onto the western hills in the morning, a rising risk of spots spreading more widely from midday with local heavy bursts, but may well stay on the drier side.
Cloud on the hills?
Early low cloud, then varied over high terrain
From dawn, cloud banks at varied elevations, most extensive to the west; upper east terrain may start above cloud. Lifting through morning to shroud most high terrain for several hours, may well at times break or lift above the summits, but returning in rain.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Early glimpses of sun will give way to mostly cloudy conditions. Varied visibility, very good where out of cloud and rain but may suddenly deteriorate.
How Cold? (at 750m)
18 or 19C, beginning to lower from the west, finishing near 16C (though warmer east where may see little change until evening).

Planning Outlook
Though the weekend, high pressure is never far away to the southwest, keeping conditions generally drier and brighter across England and Wales, though a northwesterly flow will bring some cloud to western hills. Scotland is more often cloudy with patchy rain, mostly north and west, and a rising risk of cloud and some bursts of rain more widely into Sunday with fresher air. Windier and wetter conditions are indicated next week, though day-by-day detail is currently uncertain. Monday sees a rising risk of strengthening wind and rain, at least in northern areas, then a blustery northwesterly wind draws fresher air and showers more widely through midweek; some drier, brighter windows to the east. Staying mixed into next weekend.
