Brecon Beacons
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.
Heavy rain
Near-constant heavy rain, sometimes torrential over the mountains, very wet underfoot.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
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
Widely very poor conditions on the hills: upland gales, and persistent fog and rain, or on higher areas (widely Scottish Highlands) snow. But western Scotland, mainly westernmost slopes, often dry with higher cloud base (sometimes clearing). Wales: some improvement from south during day.
Headline for Brecon Beacons
Upland gales at first; rain. Persistent fog.
How windy? (On the summits)
East veering southeasterly 30 to perhaps at first 40mph. Will ease from south through day (timing uncertain) toward or perhaps less than 20mph.
Effect of the wind on you?
Arduous walking and significant wind chill from dawn, although conditions will ease, perhaps markedly.
How Wet?
Rain on and off all day. Small risk lightning
Rain frequently morning, gradually transitioning to heavy showers: risk hail and chance thunder.
Cloud on the hills?
Fog intermittently lifting to higher tops
Covering hills early in day above 300-450m, sometimes lower. Cloud base rising intermittently toward 750m, some breaks forming - but lowering again in rain.
Chance of cloud free summits?
Almost nil rising to 30%
Sunshine and air clarity?
Dull and murky - though improving from south: occasional sun and very good visibility.
How Cold? (at 750m)
2 or 3C, tending rise slowly through day. Will feel as cold as -10C directly in the wind at first.
Freezing Level
Above the summits.

Planning Outlook
Overall little change in conditions over the coming week: the mountains extensively foggy, precipitation from time to time (although lower total rainfall in eastern Scotland and Wales than recently) and often strong southeast or easterly wind. However, a slight rise in temperature will result in thawing of lying snow from southern Scotland southwards and some thawing up to around 900, sometimes 1050m Scottish Highlands - although the chance of the return of low freezing level toward the middle of next week.
