Increasingly blustery with afternoon patchy rain west, only east later

How windy? (On the summits)

Southerly, 10 to 20mph morning, strongest in the west and soon strengthening with a southeasterly shift, reaching 30-40mph later around evening, strongest west with powerful downslopes gusts to the northwest, further deteriorating.

Effect of the wind on you?

Fairly small through morning, but becoming more blustery over higher terrain, quite soon in the west, later strenuous in exposure with gusts requiring addition effort to maintain stability in the west with notable wind chill.

How Wet?

Patchy rain arrives west afternoon, later pushing east east

Starting afternoon, a rising risk of patchy rain from the southwest, mostly light and isolated west of M74 through much of afternoon, patches drifting eastward towards the Cheviots, and only reaching more widely late in the day.

Cloud on the hills?

Mostly little, likely all clearing, returning west later

Patchy cloud around some hills mainly southwest in morning, also mist in some valleys at first. Largely breaking up or lifting above the hills into middle of day, but then returning to high Galloway slopes through afternoon, deteriorating and spreading east into evening.

Chance of cloud free summits?

80%, lowering to 30% west through afternoon

Sunshine and air clarity?

Morning sunshine, high cloud gradually building from the southwest; sunny east until at least early afternoon. High cloud widespread later afternoon. Visibility excellent, deteriorating west later.

How Cold? (at 750m)

1C rising to 5C. Always a degree milder east, where may locally reach 7C for a time afternoon. Staying elevated into nighttime. Feeling colder later in day as wind increases.

How windy? (On the summits)

Southerly 35-50mph; very gusty, not just high elevations, locally variable direction; strongest west, perhaps higher speeds.

Effect of the wind on you?

Arduous to often challenging walking with significant wind chill all day; gusts constantly affecting stability.

How Wet?

Often raining, nearly persistent west

Raining on most hills early, soon patcher east. Drizzle lingers on tops. Near/west of M74, more often raining, persistent west Galloway hills. A heavier band of rain passes east later, risk of a very heavy burst as it passes.

Cloud on the hills?

Extensive west, improvements east

Extensive cloud shrouds Dumfries and Galloway hills from middle slopes up all day, lower slopes in the morning, and locally in valleys in the south. Extensive early east, bases lifting, towards 700-800m Lothians, chance brief breaks off high tops.

Chance of cloud free summits?

10% west, 30% east

Sunshine and air clarity?

A few glimpses of weak afternoon sun, but otherwise mostly cloudy. Mixed visibility, often poor in cloud/drizzle but very good where out of cloud.

How Cold? (at 750m)

7 or 8C, to 9C eastern Borders and Cheviots. Sharply cooling west into night. Feeling like -6 to -8C in strong wind.

How windy? (On the summits)

Southwesterly 35-45mph, an easing trend with time, to 25-30mph, locally stronger over tops.

Effect of the wind on you?

Walking often strenuous on high exposed terrain, particularly early when stability will require extra effort.

How Wet?

Early drizzle, soon showery

Drizzly on high terrain at dawn, locally to middle slopes west of M74. Drizzle fades as cloud lifts, then some scattered afternoon showers.

Cloud on the hills?

Early cloud improves, most east summits clearing

Extensive over high terrain at dawn, to the middle south Galloway slopes or lower. Bases lift with time, breaks forming, summits east of M74 becoming largely clear afternoon, just fleeting caps on tops. Merrick will be slower to clear, and perhaps cloud lingers over the summit well into the day.

Chance of cloud free summits?

30%, rising to 70% east

Sunshine and air clarity?

Sun increasingly breaking out, a patchwork through afternoon. Visibility becoming excellent.

How Cold? (at 750m)

3C rising to 5 or 6C. Feeling as cold as -8C in direct wind.

Freezing Level

Above the summits.

Planning Outlook

Milder from Wednesday into the weekend, but Scottish high tops below freezing at times, locally lower in the northwest. Unsettled conditions in the immediate near-term with showers (sometimes heavy with hail and lightning), occasionally more persistent rain, accompanied by often gusty winds, gales over mountains for periods, but also brighter spells between rain. With spring sunshine, temperatures will tend to rise several degrees during daylight, often becoming warm in the valleys; slopes north of major hill groups often milder. Saturday sees continued showers, mostly north and west, but higher pressure gradually builds through late weekend into early next week, bringing fewer showers and lighter winds; chilly overnight, but fairly mild spring days. Confidence is low regarding how long high pressure will establish.
