Summary for all mountain areas

A complex area of low pressure pulls away from Scotland, but leaves a legacy of snow and rain across the Highlands, breaking up into showers through the day. Locally frequent showers for northern England, but Wales should be largely dry. Winds varied, up to gale force for a few hours, focused on the Lakes/Pennines & Snowdonia in the morning.

Headline for The Northwest Highlands

Snow/rain may persist locally. Blustery, upland gales. Improving.

How windy? (On the Munros)

A possible lull around dawn, but soon northwesterly 30 to 40mph, strongest northern summits. By afternoon, backing westerly, easing to 20-25mph on/near Skye.

Effect of wind on you?

Frequent buffeting across the hills; walking often arduous on higher areas. Significant wind chill.

How Wet?

Snow/rain locally persistent for a few hours

Areas of snow (rain below 600m), locally persistent for several hours, likely focused on western hills. Tending to break up into showers through the day, fading in afternoon.

Cloud on the hills?

Extensive, but breaks forming

Covering many hills in the morning, bases 600-800m, or lower near west coast during precipitation. Cloud base will tend to lift, with breaks to 1000m or above by afternoon.

Chance of cloud free Munros?

30% morning; 60% afternoon.

Sunshine and air clarity?

A few glimpses of sun breaking through, mainly inland during afternoon. Visibility becoming generally good, but suppressed during rain and especially snow.

How Cold? (at 900m)

Around 0C, lowering from west to -2C in afternoon. Feeling close to -15C where exposed to strongest wind.

Planning Outlook

All mountain areas of Britain from Saturday 24th March 2018

A cool westerly pattern this weekend, with temperatures sub-zero above 700-800m, and overnight frost in valleys. Scattered showers, focused on western Scotland, but plenty of dry and bright weather. Cloud breaking to many high tops and visibility excellent. A chilly breeze, although winds relatively light for many areas. Changeable next week, with frontal systems approaching from the Atlantic, but then a switch to colder northerly winds from midweek and toward Easter. The freezing level dropping widely, and very cold conditions are possible on many mountains. Further accumulating snowfalls are likely, although detail is uncertain.
