Includes all higher summits in the southern half of Wales: the Bannau Brycheiniog / Brecon Beacons National Park, southern Cambrian Mountains and highest Preseli hills.
Friday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.
Chilly
Air temperature typically 0 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Summary for all mountain areas
A few morning snow flurries in west Scotland, then dry and sunny for most. Cloudier in Wales, some light afternoon rain; high cloud gradually weakening the sun more widely. Wind strengthens from the west afternoon, most notably in Scotland where reaching gale-force in exposure by evening, severe in west around dusk.
Headline for Brecon Beacons
Increasingly windy, gales later; afternoon light rain, cloud lowers.
How windy? (On the summits)
Southwest 10mph or less from dawn into early morning. Shifting southerly and strengthening from the west, to 25-35mph during afternoon, 45mph by dusk, over 50mph for a few hours after dark, moderating a little then overnight.
Effect of the wind on you?
Mostly small in morning, but with time becoming increasingly blustery in exposure, strenuous conditions with notable wind chill developing later afternoon, further deteriorating to become difficult during evening.
How Wet?
Light rain afternoon
The morning through early afternoon is likely entirely dry. A band of rain is likely to sweep east across most hills for several afternoon hours, generally light in nature, some snowflakes on the high tops, likely breaking again late in the day. Heavier rain then well into night.
Cloud on the hills?
Mostly clear, though shrouding summits or high terrain for a time afternoon
Variable banks of cloud in the morning, these soon lifting and breaking after sunrise for clear hills. During afternoon rain, cloud banks return to terrain above 700m, momentarily lower during a heavier fall, but then rising back towards the summits late in the day.
Chance of cloud free summits?
Above 90%, lowering to 40% afternoon
Sunshine and air clarity?
Largely cloudy, some weak sun through high cloud with occasional brighter moments, but trending more widely cloudy with time. Very good visibility, a light early haze; poorer later for a time in rain.
How Cold? (at 750m)
-1 or 0C rising to +2C afternoon, staying fairly steady into night and rising up to 5C for a few overnight hours. Later, feeling like -10 to -13C in wind.
Freezing Level
700-800m at dawn, gradually lifting through morning, to clear the summits afternoon.

Rising to 80%

Bursts of sunshine, some extended periods of sun. Variable visibility, often very good but poor in showers.

Occasionally on high tops
Most cloud often confined above 700-800m, clearing all tops for periods, but briefly lower patches around 600m in showers, most frequent in west in morning.
Chance of cloud free summits?
50%
Sunshine and air clarity?
Brief moments of bright sunshine. Visibility changing suddenly from very good to very poor or briefly appalling in showers.

Planning Outlook
Showers and sunshine this weekend, windy with gales at times, and cool temperatures bringing snowflakes to some middle slopes. Variable weather regimes next week: Atlantic west-southwesterly winds likely dominant, with low pressure to the northwest of the country, bringing cloud, rain, and mild temperatures, often followed by sun, showers, and cooler temperatures; rain will be increasingly common to the high Munros, but the snowfall level will lower too during periods of cooler weather, and perhaps to high Lakeland fells, though any snow unlikely to accumulate here. Next weekend, indications of high pressure increasingly building, bringing drier and brighter conditions with mild days, though the risk remains of occasional rain and cooler temperatures, notably in Scotland.
