Summary for all mountain areas

Morning showers and fog Scottish Highlands, showers trending eastward, heavier afternoon. Dry morning England and Wales, little hill cloud, then heavy afternoon showers, frequent and locally torrential over the Pennines with a risk of lightning. Little wind, but gusty around afternoon showers, deteriorating into night.

Headline for Southern Uplands

Early fog lifts, afternoon showers, becoming heavy

How windy? (On the summits)

Northwesterly 10-15mph, some notable gusts downslope towards south Galloway. Trending northerly, then northeasterly later, may rise towards 20-25mph Cheviot late in the day.

Effect of the wind on you?

Fairly small, though occasional inconvenient gusts over high terrain and around showers. Deteriorating late in the day, notably east.

How Wet?

Afternoon showers, frequent and locally heavy

Likely dry through the morning, only an odd fleeting sprinkle. With time, showers drifting from the north, suddenly becoming more frequent afternoon. A cluster of heavy showers is likely, greatest risk in central areas, pushing west.

Cloud on the hills?

Variable banks east, becoming mostly clear west

Cloud banks at various heights at dawn, bases lifting to high terrain through morning, becoming well-broken west for several hours with clear summits. Eastern areas may see more frequent cloud caps, locally 700-800m in showers, and later some cloud caps may return to the summit of Merrick.

Chance of cloud free summits?

70%

Sunshine and air clarity?

Sunshine breaking out through morning, best west, but then a patchwork forming widely afternoon, cloudier near showers. Excellent visibility, though suddenly poor in showers.

How Cold? (at 750m)

5 or 6C, rising to 9C near and west of the M74; staying nearer 7C in the far east. Suddenly lowering several degrees around showers.

Freezing Level

Above the summits.

Patchy mist in the valleys from dawn, locally thicker and drift upslope eastern Borders and Cheviots. This soon lifts and dissipates for cloud-free hills.

Chance of cloud free summits?

90%

Sunshine and air clarity?

Widely sunny. Excellent visibility.

How Cold? (at 750m)

6C, rising slightly, up to 9C towards Ayrshire. Little or no change at the Cheviot.

Freezing Level

Planning Outlook

A core of high pressure lingers northeast of Scotland well into the week. The weather will be mostly sunny but also windy, particularly in Wales and the southern Pennines; challenging conditions are likely for several days on high Welsh mountains, powerful gusts over tops and downslope to the west requiring great effort to maintain stability. Despite Monday showers, dry ground conditions, warm temperatures, and wind bring a high risk of wildfire. More settled in Scotland, though breezy in the west, most hill cloud in the east. Detail becomes uncertain into next weekend, but a rising risk of showers and longer spells of rain as pressure begins to drop.
