Summary for all mountain areas
Windy across higher areas, particularly so those near the north Irish Sea and Scottish Highlands (where widespread upland gales). Drizzly rain will affect some western mountains, but otherwise extensively dry. Much mountain terrain at least partly frozen, particularly morning.
Headline for Brecon Beacons
Windy west Wales; areas of sunshine. Terrain partly frozen.
How windy? (On the summits)
Southerly 25mph east Wales, but 30 locally 35mph SW Wales and Cambrian range.
Effect of the wind on you?
Fairly small east Wales, but arduous walking and marked wind chill open ground west Wales.
How Wet?
Risk isolated shower SW Wales
Small risk of a drizzly shower Preseli hills.
Cloud on the hills?
Mostly confined to higher slopes
Preseli east to western Brecon Beacons: frequent cloud above 450m. Elsewhere, risk patches some higher slopes, but hills extensively cloud free.
Chance of cloud free summits?
80%
Sunshine and air clarity?
Extensive sunshine east Wales; cloud coming and going elsewhere; little sun southwest Wales where hazy. Elsewhere, pockets of mist after dawn will clear to very good visibility.
How Cold? (at 750m)
0C tending to rise toward 2C through morning.
Freezing Level
700m rising above the summits in morning. Frost valleys morning.

How windy? (On the summits)
Still considerable uncertainty: Southwesterly 20 to 35mph; later abruptly northwesterly 30 to possibly 45mph.
Effect of the wind on you?
Temporarily small, but zones where wind chill significant and walking difficult - these challenging conditions could set in abruptly.
How Wet?
Periods of rain
Areas of rain will circulate within general low pressure, perhaps falling as snow on higher tops by dusk - when it will often be dry, although still risk of showers.
Cloud on the hills?
Fog extensive, although cloud base likely to rise
Fog in some areas from lower slopes up, and few breaks above 600m. Probably an improvement as most cloud rises to above 750m - timing uncertain.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Sunshine occasionally, most likely afternoon. Regions of very poor visibility - but often very good later in day.
How Cold? (at 750m)
3C
Freezing Level
Above the summits.

Snow/hail showers
Occasional snow and hail showers, mainly morning. Very few showers will reach east Wales. Rain below 350m.
Cloud on the hills?
Extensive higher areas
Fog frequent, in morning rarely clearing above 750m. By afternoon, cloud intermittently clearing all but perhaps highest summits (above 1000m). Near showers, cloud below 500m.
Chance of cloud free summits?
70%
Sunshine and air clarity?
Intermittent sunshine; most sun east Wales. Visibility mostly very good.
How Cold? (at 750m)
-1C. Will feel as cold as minus 8C directly in the wind.
Freezing Level
700m.
Planning Outlook
On Sunday, uncertainty in forecast detail remains within a complicated area of low pressure. Beyond, cold with higher terrain frequently or almost permanently frozen most or perhaps all next week. Wales, and perhaps N England, will see one or two incursions of much warmer air together with areas of persistent rain and snow. Some higher areas may have a considerable snow. Overall, low precipitation across Scotland, but marked exceptions: here too, where the frequently northerly wind rises over mountains (with the sea directly to the north), accumulations of snow may well be considerable.
