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.
Snow
Snowfall continuous or frequent over the mountains, beware of conditions becoming challenging on higher terrain. At lower elevations falling as rain.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
Cold
Air temperature below 0C all day on higher mountains. Significant chill factor if exposed to strong winds. Suitable protective clothing required.

Summary for all mountain areas
A change in the pattern as cold air will have extended south overnight. Nearly all mountain terrain frozen in Scotland whilst further south, particularly higher terrain progressively freezes. Patches of snow, at times persistent Wales, but otherwise total precipitation small.
Headline for Brecon Beacons
Terrain increasingly freezing; intermittent snow.
How windy? (On the summits)
Northeasterly 40-45mph, risk stronger for periods. A chance of lighter wind at and before dawn, but a sudden deterioration.
Effect of the wind on you?
Arduous to challenging walking with severe wind chill; foot placement and balance constantly challenged. Severe wind chill.
How Wet?
Frequent snow, rain to lower slopes
A mix of steady snow, lasting a couple of hours or so (most persistent east Wales), and heavy but briefer snow showers. Rain below about 300 or 400m.
Cloud on the hills?
Extensive, may begin to improve later
Cloud shrouds most mountains from 500m up well into the day. Fog may begin to lift and break late in the day.
Chance of cloud free summits?
20%
Sunshine and air clarity?
Overcast. Very poor visibility in snow, though at times good.
How Cold? (at 750m)
-1 or -2C, though just above freezing point at dawn south of A40 (through Brecon). Will feel as cold as minus 14C in the wind.
Freezing Level
Varying between 500 and 700m, although above southern summits at first. Higher terrain increasingly frozen.
