Includes all higher summits in the southern half of Wales: the Bannau Brycheiniog / Brecon Beacons National Park, southern Cambrian Mountains and highest Preseli hills.
Tuesday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchwork of cloud and sun
Dry most or all day. A mix of cloud and sunshine. Occasional cloud banks drifting over higher slopes, lifting above the tops.
Cool to mild
Air temperature 5 to 10C on higher terrain. Comfortable temperatures on lower terrain, but feeling chilly if exposed to wind higher up, especially if stationary. Pack extra layers.

Fine drizzle where in cloud, mostly south and western areas, but most slopes stay dry.
Cloud on the hills?
Fairly extensive early, improving afternoon
Low cloud likely to cover many hills from 300 to 500m upward south and western areas. Mostly above 600m northward, and improving in the afternoon, becoming well broken, breaks to summits probable.
Chance of cloud free summits?
20% rising to 60%
Sunshine and air clarity?
Largely cloudy in the morning, murky southwestern areas, locally better visibility east and mid-Wales. Improving more widely afternoon with sun breaks, but some haze around.

From dawn, an extensive layer of cloud from lower slopes upward on southern aspects; north of high tops will see higher bases and perhaps some clear hills. Bases tending to lift with time, a possibility of breaks in the east, but likely becoming more extensive later.
Chance of cloud free summits?
30%

Planning Outlook
West to southwesterly winds prevail from mid-week into the weekend as areas of low pressure move toward northwest Scotland; regular rainfall here, most frequent and heavy over western mountains. Bands of rain from the west also affecting England and Wales. Milder temperatures from mid-week with freezing levels above all summits for a few days, substantial thawing to the summits in England and Wales, some high slope thawing in Scotland too. Extensive gales, only a brief easing on Wednesday, then soon unsettled again with cooler temperatures returning, showery west with bands of rain passing east, some snow on Scottish Munros. Some drier, brighter weather is possible over the weekend, though interruptions by bands of rain are likely with low confidence in detail.
