Summary for all mountain areas
A slow-moving front from the west brings rain and low cloud to western Scotland, turning to snow on tops as colder air arrives; freezing level later below 800m. Patchy rain encroaching further into Cumbria with time. Some heavier thundery bursts possible in Wales. Strong southerlies ease and turn W-NW'ly.
Headline for Brecon Beacons
Some weak sun early, trending cloudy with rising risk of showers
How windy? (On the summits)
Southerly 20-25mph, a gradual easing, briefly 15mph or less afternoon, then reorienting northerly into evening/night and restrengthening, up to 30-35mph high western tops.
Effect of the wind on you?
Feeling blustery in exposure in the morning, improving to fairly small effects for a least several hours. Afternoon into evening brings renewed nuisance wind, perhaps strenuous conditions in exposure as night approaches.
How Wet?
Afternoon showery rain
The morning likely dry, then a risk of showers in the afternoon which may be locally heavy, risk isolated rumble of thunder. Into evening, patchy rain lingers.
Cloud on the hills?
Clear periods, deteriorating with time
Ribbons/banks of cloud at several elevations in the morning, some ragged patches possible on lower slopes too, but soon lifting and dissipating. Caps come and go on high tops for several hours before a more extensive sheet of cloud arrives from the west late in the day.
Chance of cloud free summits?
70% lowering to 30%
Sunshine and air clarity?
Weak sun through a veil of high cloud through morning, perhaps afternoon too but cloud increasingly thickening from the west. Visibility limited by haze.
How Cold? (at 750m)
7C lifting to 8C. Lowering slightly in the west later, then several degrees into night. Feeling near freezing in early wind.
Freezing Level
Above the summits.

30%

Largely overcast, some brighter moments to the west. Excellent visibility away from cloud/rain.

Cloud breaking to give occasional sun. Visibility very good, may be hazy lower down.

5 or 6C, slight rise into afternoon.

Planning Outlook
Higher pressure extends back across the country to bring dry conditions on Saturday, feeling mild in sunshine by day after a chilly start. More cloud by Sunday as weak fronts encroach in from the west, some drizzly rain moving into western Scotland. Patchy rain likely in the west at least early in the new week, likely dropping back just below freezing on the Munros for a time with some snowfall on higher areas. Winds fairly light early week, then a risk of strengthening southwesterlies later in the week; changeable weather conditions with spells of rain coming in from the Atlantic. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, only very patchy snow remains around highest tops in England and Wales.
