Last updated Fri 1st May 26 at 2:58PM

Summary for all mountain areas

Very varied weather across the country: wettest in far northern and later eastern Scotland as cold and blustery weather penetrates southwards. Rain will later set in from south across Wales. Otherwise, areas of low cloud and pockets drizzle lifting to give patchy sunshine.

Headline for West Highlands

Colder. Showery rain, mainly afternoon.

How windy? (On the Munros)

Direction varied; widely 10mph or less.

Effect of the wind on you?

Negligible morning, but from north marked wind chill and and fairly widely uncomfortable walking in gusty winds (including on some lower slopes).

How Wet?

Rain becoming more widespread

Largely dry, although a few patches of showery rain until mid afternoon when in places the rain setting in for an hour or two - there may be heavy, possibly thundery bursts.

Cloud on the hills?

Generally extensive - though may clear most summits for a few hours.

Particularly toward the coast, cloud may for periods in morning form below 300m. Generally though, by late morning, most cloud above 900m, with some higher tops clearing. Will deteriorate again in rain, fragments from forest canopies up, and becoming extensive above 450 to 600m.

Chance of cloud free Munros?

30%

Sunshine and air clarity?

Occasional sunshine. The air very clear, but visibility poor where raining.

How Cold? (at 900m)

Between 5C near the coast and 8C, perhaps 10C well inland afternoon.

Freezing Level

Above the summits.
