Summary for all mountain areas

Fronts will clear slowly south-eastwards across England and Wales, bringing rain and low cloud for several hours, then becoming brighter from the north. Scotland sees scattered showers, these becoming heavier and more widespread later, of snow on highest summits.

Headline for Southern Uplands

Cool and breezy. Early rain clearing; cloud lifting.

How windy? (On the summits)

Westerly; post-dawn briefly up to 40-45mph, but most of the day around 20mph, occasionally less. By evening nearer 25mph, or 30mph by sunset.

Effect of wind on you?

Mostly fairly small.

How Wet? (Precipitation and its impact)

Early patchy rain fading; becoming largely dry

The remnants of overnight rain will be on and off for a few hours early morning, but breaking up and clearing southeastwards, soonest in Galloway, and by midday in Cheviots. Toward sunset and after dark, a few showers will spread from the west.

Cloud on the hills?

Extensive at first, but lifting

Widely covering the hills above 500-600m at first, but cloud base lifting as rain fades, and most tops clearing into the afternoon, perhaps sooner.

Chance of cloud free summits?

40% morning; 80% afternoon.

Sunshine?
Air clarity (below cloud)

Cloud breaking up in morning to give a patchwork of sunshine. Visibility improving, becoming excellent.

How Cold? (at 750m)

5 to 7C

Freezing Level

Above the summits.

Planning Outlook

All mountain areas of Britain from Thursday 21st June 2018

High pressure builds from the west later this week to bring plenty of fair weather over the next week to 10 days. This weekend has a risk of patchy rain and low cloud for the north-western Highlands brought in on fresh westerly winds, otherwise it will be dry with many summits clear. Rather cool in the short term, but temperatures rising into next week, and eventually it may become widely hot and humid. By the end of June this may break into thunderstorms.
