Summary for all mountain areas

A warm and humid day with extensive low cloud affecting many hills and pulses of thundery rain moving north through the morning followed by further clusters of showers or thunderstorms. Becoming largely dry through the afternoon across Wales as winds veer southwesterly. Best of the cloud breaks will be towards the west coast.

Headline for West Highlands

Rain/low cloud extending north, risk lightning. Best breaks in west.

How windy? (On the Munros)

Easterly; initially widely 30-45mph, sudden ferocious gusts lower slopes & valleys. Will drop to 10-15mph from south by the afternoon.

Effect of wind on you?

Risk of arduous walking conditions across higher terrain, and in places very gusty to lower slopes. Easing by afternoon.

How Wet? (Precipitation and its impact)

Rain extending north; risk lightning

Low confidence of detail/timing: A swathe of rain, focused across eastern areas and in places heavy and thundery, will spread north across the Highlands through the morning. Will tend to become more showery and ease for a time in the afternoon, before further thundery rain arrives late on.

Cloud on the hills?

Very extensive

Cloud extensive across the hills, with patches from lowest slopes upward, mainly central highlands. May break to or above highest summits occasionally toward west coast, and possibly more widely Arran to Mull and then Loch Lomond NP by evening.

Chance of cloud free Munros?

20%, but 50% toward west coast.

Sunshine?
Air clarity (below cloud)

Little or no sunshine. Very hazy - even when dry. Very poor visibility in heavy rain.

How Cold? (at 900m)

9C, increasing humidity.

Freezing Level

Above the summits.

Planning Outlook

All mountain areas of Britain from Tuesday 25th June 2019

A very warm and humid week ahead, will become hot and exceptionally humid for a few days from around the middle of the week with the risk of isolated bursts of rain/thunderstorms; although many areas will miss these and stay dry. Some periods of low cloud across the hills; especially focused across eastern hills. Winds from an east or southeasterly direction and blustery at times. Increasing risk of a thundery breakdown over the weekend with fresher conditions arriving from the west.
