Summary for all mountain areas
Widespread gales, powerful gusts over tops and down northern slopes, severe at times in Scotland, particularly west. Persistent rain for many, brief dry windows east (notably Pennines), then heavy rain sweeps east afternoon, followed by showers, only easing late in the day. Mild air, but feeling cold in wind.
Headline for Brecon Beacons
Patchy rain/drizzle, heavier for a time; gusty gales
How windy? (On the summits)
Southerly 40-50mph; powerful gusts, not just high slopes, approaching 55mph downslope to the north. A southwesterly trend later, speeds possibly slightly easing for a few afternoon hours.
Effect of the wind on you?
Arduous to often challenging walking with significant wind chill all day; gusts constantly affecting stability, strongest speeds will make forward progress difficult.
How Wet?
Drizzle, patchy rain, then heavy rain afternoon, later showers
A persistent drizzle over the summits through morning, to the middle slopes early, with patchy rain occasionally drifting from the southwest too. Rain sets in persistent and heavy for several afternoon hours, breaking into heavy showers, these easing into evening.
Cloud on the hills?
Extensive early, improving but variable
Extensive to at least middle slopes at dawn, to lower slopes or valley level southern slopes. Bases lift somewhat, 500-700m, some higher breaks briefly, but returning extensively again for a few afternoon hours. Breaking more later for a chance of clear summits.
Chance of cloud free summits?
20%, 40% later in the day
Sunshine and air clarity?
Mostly cloudy, a few fleeting bursts of sun, best chance of sun later afternoon as evening approaches. Often poor visibility in cloud and rain, locally very good at times; variable through the day.
How Cold? (at 750m)
7 or 8C morning into afternoon. Beginning to cool later afternoon from the west, 4 to 5C by evening. Feeling like -5 to -8C in direct wind.
Freezing Level
Above the summits.

Effect of the wind on you?
Fairly small at times, but feeling blustery in exposure, particularly in the morning when feeling chilly.

Early drizzle, some light showers
Drizzly over high terrain much of morning. Drizzle will ease, then scattered light showers will occur here and there through afternoon. A chance of some light rain later in the day.
Cloud on the hills?
Lifting to the summits, clear periods too
Most terrain above 700m in cloud from dawn, to 500m south and western slopes, bases rising to mostly just caps on the high tops by midday, clear periods likely too.
Chance of cloud free summits?
30% rising to 60%
Sunshine and air clarity?
Sunshine increasingly breaking out to a patchwork afternoon, slow to break in the west. Visibility becoming very good.

Southerly 30-35mph, soon shifting southwesterly, some variability, reaching 40mph or higher over summits at times.
Effect of the wind on you?
Walking often strenuous in exposure with considerable wind chill, a trend towards more arduous conditions later.

Patchy rain through the morning, setting in persistent and heavy for a time (perhaps only a few hours). Breaking into scattered showers that will ease with time.
Cloud on the hills?
Variable, most southwest, more extensive for a time
From dawn, cloud shrouds the high tops, variable lower banks, mostly west of Brecon. Filling in more widely to middle slopes as rain sets in, then breaking again later as rain eases, some breaks off summits.
Chance of cloud free summits?
30%, rising to 50%
Sunshine and air clarity?
Mostly cloudy, dull for several hours as rain sets in with poor visibility. Glimpses of sun later with good visibility.

6 or 7C. Feeling as cold as -5C in direct wind.
Freezing Level
Above the summits.
Planning Outlook
Unsettled conditions as the weekend approaches: showery on Thursday (local hail and lightning in Scotland), more rain and often heavy on Friday, accompanied by gusty winds, gales over mountains for periods; some bright spells on Thursday and later Friday too. Temperatures will tend to rise several degrees during daylight, even when cloudy, and often becoming warm in the valleys; slopes north of major hill groups often milder too. Saturday sees continued showers, mostly north and west where staying blustery, but a trend towards higher pressure building through late weekend into early next week. Confidence in detail for oncoming high pressure remains very low: a risk of chilly easterly wind for a time with showers, mostly east and southern areas.
