Summary for all mountain areas

High pressure builds in from the west, and a weak front which crosses the country in the early hours moves away eastwards. A largely dry and bright day, with cloud breaks to many higher tops. Windy in the morning, up to gale force for the Pennines and Wales, but tending to ease. Temperatures sub-zero again on the mountains.

Headline for Southeastern Highlands

Wind easing. Dry most of the day; rare snow flurries.

How windy? (On the Munros)

North to northwesterly, 30-35mph at dawn, but tending to ease slightly through day, toward 20-25mph by afternoon.

Effect of wind on you?

Buffeting and significant wind chill higher areas in morning, but conditions improving through the day.

How Wet?

Dry most or all day

A chance of residual snow (rain below 600m) on some hills near & east of Glenshee at first, but soon all fading, leaving most of the day dry.

Cloud on the hills?

Becoming confined to higher tops; breaks increasingly

Banks of cloud below 800m in the morning, may linger locally for a few hours. Cloud base lifting to 900-1000m, and breaks forming toward many higher tops.

Chance of cloud free Munros?

50% morning; 70% afternoon.

Sunshine and air clarity?

A patchwork of sunshine. Visibility generally very good.

How Cold? (at 900m)

-1C Feeling close to -15C where exposed to strongest wind post-dawn.

Freezing Level

Around 800m, but lowering a little by dusk toward 600-700m.

Planning Outlook

All mountain areas of Britain from Wednesday 21st February 2018

High pressure which briefly resides across Britain will become centred strongly over Scandinavia later this week, paving the way for very cold easterly winds to develop toward the end of February. Substantially dry conditions for the rest of this week, and most likely through the weekend. A risk of snow developing on eastern hills as the easterly winds arrive. After a brief lift above freezing at the start of this week, temperatures will be below freezing on the mountains for the foreseeable future, so the current snow-pack will substantially remain in place; probably well into March.
