Summary for all mountain areas

Dawn gales over summits of south Scotland and north England, strongest wind moving north, but staying breezy in northern parts of England and Wales. Showers for many in the morning, soon easing with sun breaks, but remaining frequent with heavy bursts in west Scotland; some rain approaches Wales later afternoon.

Headline for Brecon Beacons

Scattered showers, mostly east; blustery early

How windy? (On the summits)

Southwesterly 20-25mph most of the day, through 30-35mph just at and before dawn. Occasionally stronger in the west and trending towards a sustained 30mph westernmost hills around dusk.

Effect of the wind on you?

Fairly small at times, but feeling blustery in exposure, particularly in the morning when feeling chilly and again later in the day in the west.

How Wet?

Some fine drizzle, scattered showers

Fine drizzle drifting around high terrain from time to time in cloud. Also scattered showers will occur much of the day, generally light in nature, most frequent on eastern hills. Later afternoon into evening may see a few hours of more widespread light rain.

Cloud on the hills?

Lifting to the summits, clear periods too

Most terrain above 600m in cloud from dawn, to 500m or lower south and western slopes. Bases soon rising to mostly just caps on the high tops by midday, clear periods likely too between showers. As evening approaches, a risk of more extensive cloud returning to high terrain for several hours.

Chance of cloud free summits?

30% rising to 60%

Sunshine and air clarity?

Sunshine increasingly breaking out to a patchwork afternoon. Visibility becoming very good, though may suddenly deteriorate where showers occur.

How Cold? (at 750m)

5C, rising to 6C, 7C eastern hills. Feeling as cold as -5C in early wind.

60%

Planning Outlook

Friday stays windy with a band of rain passing east across the British Isles. A settling trend begins on Saturday, showers lingering in western areas, then the most settled conditions of the weekend on Sunday. Light or even negligible wind by Sunday with cool-to-mild temperatures, though perhaps on the chillier side in Scotland. The stronger sunshine will feel mild despite chiller temperatures. More certainty regarding a dominance of high pressure next week: a mix of cloud and sun, often dry, and cool temperatures. Greatest chance of scattered showers in eastern areas, more cloud here, and some low fog in the mornings as well. Easterly wind at times quite blustery and gusty in England and Wales, generally lighter Scotland.
