Patchy rain toward the south of the Highlands, and tends to become more persistent west coasts. Varied low cloud, higher breaks generally north. A swathe of rain and low cloud northern England and southern Scotland. Clusters of showery rain for Wales, heavy bursts with local thunder. Wind speeds varying.
Windy much of day, up to gale-force. Showery bursts.
South-southeasterly 40-50mph at dawn, powerful gusts 60mph at first, easing through morning to 25mph for a few hours, turning southwest later westerly, rising again quickly by afternoon to 40-50mph, slight drop through dusk.
Strenuous walking, balance challenging in places, feeling distinctly chilly in exposure; a few hours of improvement middle of day, but still breezy, then deteriorating to be arduous again in afternoon.
Heavy rain at first, showery bursts passing east during day
Rain fairly persistent from before dawn, heavy widely for a couple of hours, briefly fading in morning, but soon further heavy bursts cluster together from southwest, passing east middle of day into early afternoon, chance of isolated thunder. Tending to fade later, but leaving patchy light rain mainly western hills into evening.
Extensive
Shrouding many hills much of the day, from low-mid slopes upward southern areas, highest bases toward eastern mid-Wales. Some brief moments of improvement possible, a greater chance late in the day in east.
20%
Overcast, mostly dull, poor visibility in rain, locally better if dry east Wales areas for a time; tending to improve later.
6C rising to 9 or 10C afternoon, then dropping again into evening. Feeling below freezing in the wind, near -5C early and late on high tops.

Southwesterly 25-35mph, gusty over tops, particularly early in the day; deteriorating, sustained speeds 35mph+ later.
Ease of walking always affected, including to low slopes, more strenuous over tops where feeling chilly., and deteriorating.
Little rain expected until late
A few spots of light rain here and there drifting from the southwest, perhaps a fine drizzle on the summits in the early hours, but most hills substantially dry. Late in the day, some risk of a broader area of rain developing.
May cling to high terrain
Fairly extensive cloud above 600m in the morning, lowest bases to the southwest as low as 400m. Lifting with time, perhaps clearing most or all terrain, but a risk of caps clinging to the high summits.
Rising to 60%
Weak sunshine through high cloud, trending patchier through afternoon. Good visibility, though some haze west.
8C rising to 10C, or 11C east hills; less rise southwest areas. Feeling near freezing in strongest wind.

Southwesterly 15 to 25mph.
Fairly small effect on walking, but feeling blustery and a noticeable chill on exposed high terrain.
Rain then odd showers
A band of rain clears eastward early morning, then drier but a scattering of showers.
Breaks to tops
Varied cloud banks mostly western hills and higher tops in morning, lifting higher up with breaks best in east Wales.
50%
Occasional sun by middle of day. Visibility very good after early rain clears.
5 to 7C. Feeling below freezing directly in the wind.

Generally unsettled next week - showers affect most hills Monday and Tuesday, lowest cloud and most persistent rain along western slopes, but with some breaks as well with sunshine. Risk of a deeper area of lower pressure from Wednesday or later bringing widespread strong winds, probably gales over many summits, with prolonged heavy rain. Temperatures trending milder again into next weekend, pressure may begin to rise in the south to give drier weather more widely with time.
