Summary for all mountain areas
Bright sun and showers, mostly chilly temperatures. Showers cluster for steady falls and heavy bursts with hail, first in Scotland (snow on high Munros), then into England and Wales afternoon. Showers tend to scatter into evening, though sometimes returning to north parts of Scotland and Wales.
Headline for Brecon Beacons
Patchy sun, some afternoon showers forming
How windy? (On the summits)
Northwesterly 20-25mph, some notable gusts forming over high tops, and tending to slightly strengthen and shift northerly later.
Effect of the wind on you?
Mostly fairly small, some blustery moments forming on the high tops.
How Wet?
Few showers, a brief cluster afternoon
Some light showers will drift onto the Cambrians, only a few reaching east into the Brecon Beacons in the morning. Afternoon brings a greater risk of showers more widely, greatest risk of a heavy burst to the east.
Cloud on the hills?
Mostly clearing
Some ragged cloud clings to the hills around dawn after overnight rain, this lifting and generally dissipating for clear hills. A few caps may drift over high tops of Cambrians and western Brecon Beacons around showers.
Chance of cloud free summits?
Rising to 70%
Sunshine and air clarity?
Often sunny, some patchy high cloud around. Good visibility, a little haze.
How Cold? (at 750m)
5 or 6C, may rise to 7C easternmost hills exposed to sun.
Freezing Level
Above the summits.

Chance of cloud free summits?
90%
Sunshine and air clarity?
Mostly sunny, a little high cloud may form. Very good visibility.

Planning Outlook
A window of more settled weather this weekend as a core of high pressure builds over Scotland. Clear night skies allow for chilly mornings with ground frosts, some valley mist particularly in Scotland. Mostly sunny, though locally a little cloud lingering on some high slopes; an easterly breeze will keep the skies a touch cloudier in England and Wales, chance a little rain for England on Sunday with building cloud, though detail currently uncertain. The following week starts with some rain and wind in Wales, more settled to the north but with strengthening wind and building cloud as well. Forecast confidence is low into the week: a general trend towards unsettled conditions is indicated, soonest in the southeast. Scotland may stay largely dry into mid-week, northernmost areas clearest of cloud.
