Summary for all mountain areas

Areas of snowfall will pivot in from the east to affect many areas of Scotland and Northern England through the day. Accompanied by upland gales giving severe wind chill for periods, but a substantial lull is likely S Pennines. Across Wales, snow showers later give way to persistent snow.

Headline for Southeastern Highlands

Upland gales, severe wind chill and snow; periods of whiteout higher slopes.

How windy? (On the Munros)

North or northeasterly, speeds may vary, but for periods risk 40-50mph high tops.

Effect of the wind on you?

Prepare for difficult conditions and severe wind chill on the mountains.

How Wet?

Periods of snow

Persistent snow coming in from the east likely to set in extensively for periods across the mountains. Becoming sleet or rain on lower slopes with time. Whiteout at times on higher terrain.

Cloud on the hills?

Fairly extensive

Blanket cloud likely to cover many mountains much of the day, particularly where snow sets in. Risk forming to lower slopes near and east of Glenshee.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Sun unlikely. Visibility likely widely very poor, appalling conditions in snow and cloud.

How Cold? (at 900m)

-4C, rising to -2C, in places 0C. Will feel closer to -20C or below in exposure to the strongest winds.

Freezing Level

Varied. Terrain frozen from most glens up in morning, and locally may stay near zero. Tending to rise to 800-1000m.

Planning Outlook

Cold weather patterns are likely to prevail well into December. A period of constant freeze, at least on the Scottish Munros, but often near or below zero on many lower summits across Britain. Upland terrain becoming extensively snow covered as bands of precipitation circulate slowly around low pressure - substantial snowfalls likely across many uplands, and snow may well lie for periods to lower slopes. Wind speed and direction will vary considerably, occasionally gale force. An east or northeasterly common across northern Britain.
