Summary for all mountain areas

Heavy, thundery rain moves north through Wales and England, showery thunderstorms following in Wales; beware sudden gusts, rapidly rising streams, and local flooding. Hill cloud and a little patchy rain in east Scotland; much of west Scotland clear of cloud, though some haze around.

Headline for Southern Uplands

Light spotty rain, best of sunny breaks west; warm and humid

How windy? (On the summits)

East-southeasterly 15-25mph; a gusty start, approaching 35mph west, but an easing trend with time.

Effect of the wind on you?

Nuisance gusts in the morning hours will ease, though walking could be strenuous on exposed western terrain at first. Fairly small effects much of afternoon.

How Wet?

Largely dry start, patchy rain gradually sets in from south

A few spots of rain south and east early, many hills start dry. Patchy rain increases in the south and east with time, and may set in on south and eastern slopes late in the day with a risk of extended heavy falls into night.

Cloud on the hills?

Fairly extensive east, lifting west

Most slopes shrouded just at dawn, lifting towards and then above high tops west; eastern hills unlikely clearing above 600-700m. May break up somewhat for a time but gradually returning more extensively over eastern tops and later more widely as the day ends.

Chance of cloud free summits?

Rising to 70% west slopes for a time

Sunshine and air clarity?

Patchy sunshine, some extended sunny periods to the west; more often cloudy to the far east. Fog and haze make for poor visibility east, improving west.

How Cold? (at 750m)

12 or 13C rising to 15C west, a degree cooler east; feeling humid.

Freezing Level

Above the summits.

How windy? (On the summits)

Variable 10-15mph, orienting generally westerly, local breezes approaching 20mph.

Effect of the wind on you?

Mostly small, but variably becoming breezy in some spots.

How Wet?

Persistent rain, heavy east

Rain rarely ceases on hills near/east of the M74, heavy bursts and risk of thundery downpours. Lighter westward, may break up for periods, notably later. Fast-flowing streams, risk local flooding.

Cloud on the hills?

Extensive

Cloud shrouds the hills in the morning, widely to middle slopes, to lower north and eastern hills. May locally lift, but eastern hills covered likely all day. A few higher breaks may begin to form late in the day, though only reaching western summits (if at all).

Chance of cloud free summits?

20%

Sunshine and air clarity?

A few brighter glimpses may break out west, but otherwise overcast, often dull with poor visibility.

How Cold? (at 750m)

12 to 14C.

Freezing Level

Above the summits.

How windy? (On the summits)

Generally westerly 10-20mph, quite variable and sometimes lower speeds.

Effect of the wind on you?

Mostly small.

How Wet?

Early drizzle, patchy rain increases

A little drizzle in early cloud, this mostly fading. Patchy light rain here and there, tending to increase in frequency, a risk of longer falls with heavy bursts late in the day.

Cloud on the hills?

Fairly extensive

A sheet of cloud shrouds the hills from at least middle slopes up in the morning. A lifting tendency, some breaks may approach 800m or higher at times, but bases will lower again and may fill in more extensively on south slopes later.

Chance of cloud free summits?

30%

Sunshine and air clarity?

A few glimpses of weak sun, trending overcast. Visibility becomes very good where cloud lifts.

How Cold? (at 750m)

11 or 12C, mildest east and may rise a degree here.

Freezing Level

Above the summits.

Planning Outlook

Heavy, thundery rain affects England, Wales & eastern Scotland on Friday, prolonged heavy falls bringing a risk of local flooding. A westerly wind will establish over the weekend, drawing cloud and drizzle onto western high terrain, several frontal systems sweeping more broadly across the country. The strongest wind and heavy rain may pass mostly across England and Wales, with the lightest rain in Scotland. Hills often shrouded in cloud, low patches around rain; only local improvements. A west-southwesterly weather track prevails next week: cloud and drizzle on western hill groups (particularly west Scotland), breezy with areas of rain regularly spreading widely at times. A few brighter interludes through the week, and a chance of a more settled window in the south into the weekend.
