Some early showers from south Scotland to north Wales, largely fading with sun breaks; south Wales is dry and brighter. Strong wind widely, easing Wales and north Scotland.

Headline for Southern Uplands

Strong wind, risk early gales; early showers largely fade

How windy? (On the summits)

Westerly 35-45mph, to 50mph Cheviot at dawn; easing to 30-35mph for several hours, a northwesterly trend, but then rising back to 40mph afternoon with stronger gusts over tops.

Effect of the wind on you?

Strenuous walking with wind chill in exposure all day; some variability, difficult conditions in the far east at dawn.

How Wet?

Early showery rain mostly eases

Showers drifting from the northwest, generally light in nature and well scattered, and many hills substantially dry, especially late in the day; greatest risk of notable falls in the early hours.

Cloud on the hills?

Lifting to the tops, likely above most east tops

Fairly extensive across high terrain in the morning, lowest bases Ayrshire hills where locally to 500-600m. Lifting, likely above the summits for several hours, but some banks may variably fill in over more high terrain later, greatest risk Borders and Galloway hills.

Chance of cloud free summits?

Rising to 60%

Sunshine and air clarity?

Glimpses or bursts of sunshine, likely a cloudier spell in the mid/later afternoon. Very good visibility away from cloud and rain.

How Cold? (at 750m)

Chance of cloud free summits?

60%, deteriorating afternoon

Sunshine and air clarity?

Mostly sunny morning, cloud shrouding the sky as afternoon goes. Very good visibility.

How Cold? (at 750m)

7 to 11C; variable throughout the day, but typically coolest east, only rising later.

Freezing Level

Above the summits.

Planning Outlook

Sunday will be a clearing day for most under a core of high pressure: early rain in Scottish Highlands easing, most cloud lifting off all hills except the north of Scotland, and good sunshine through weakened by high cloud. Temperature more widely mild, warm in Wales. Into next week, a mixed southwesterly pattern remains, windy at times with periods of rain, drizzle and low cloud most persistent in the west. Warmest in England and Wales, but may stay cooler in Scotland as low pressure to the northwest recycles air from the north Atlantic back onto the Munros. Tuesday into Wednesday shows indications of a wetter and windier spell. Pressure generally trending higher later in the week, but extensively settled weather remains elusive until at least the following week.
