Summary for all mountain areas

Sun breaking out afternoon over Wales and the Pennines with milder temperatures, though a chill in wind.

Headline for Cairngorms NP and Monadhliath

Severe gales; drizzle south and west slopes

How windy? (On the Munros)

South-southwesterly 50-60mph. Powerful gusts over high terrain and to some lower slopes too, risk up to 70mph in exposure in the morning. An easing trend begins overnight.

Effect of the wind on you?

Mobility widely difficult with significant wind chill; any stability challenges over high tops likely result in being blown over and pushed.

How Wet?

Some drizzle, driest N Cairngorms

Frequent/persistent drizzle from Ben Alder to summits near/east of Drumochter. Mostly just drizzle in the wind elsewhere, driest northern Cairngorm plateau, particularly east of Ben Macdui. Rain approaches western mountains later afternoon.

Cloud on the hills?

Blanket of fog - highest base N Cairngorms and Deeside

Blanket fog over Monadhliath, Drumochter and south Cairngorms, bases from 400-600m; occasional higher breaks on Deeside hills and north Monadhliath to 800m. North Cairngorm slopes clearer, mostly above 900m.

Chance of cloud free Munros?

Almost nil Cairngorm plateau, 20% Monadhliath

Sunshine and air clarity?

Overcast and dull, although pockets of sun and very good visibility northern Monadhliath east across the lower slopes of the northern Cairngorm plateau.

How Cold? (at 900m)

5C most of the day, 6C north Cairngorms. Into evening, a cooling trend begins from the west, dropping several degrees widely overnight. Feeling like -10 to 13C in strongest wind.

Freezing Level

Above the summits during daylight, lowering onto high terrain overnight.

Chance of cloud free Munros?

Rising to 80%

Sunshine and air clarity?

Mostly sunny though some high cloud around. Excellent visibility.

How Cold? (at 900m)

Planning Outlook

Pressure begins to rise on Wednesday, bringing fairly widely settled conditions across the country. Some cloud and spotty light rain lingers in north England/south Scotland for a few days, elsewhere becoming mostly sunny; valley fog in many lowland areas early, lifting and dissipating after sunrise for clear hills. Generally milder temperatures and light wind but the occasional stronger gust. East Scotland stays cooler for a time, some overnight frosts possible under clear-sky nights. Over the weekend, first indications of a cool easterly wind building, perhaps some patchy rain here and there. Into next week, detail is uncertain; low pressure may occasionally unsettle the weather, brining cooler, wetter, and windier periods.
