A very severe day on the hills, with storm force winds extensive. Precipitation will vary from heavy sustained snowfall and whiteout northern Scotland, to little if any along the spine of Britain from the southernmost highlands southwards.
Headline for Cairngorms NP and Monadhliath
Extreme conditions: storm force upland winds; whiteout.
How windy? (On the Munros)
Northerly; substantially 55 to 75mph, gusts may approach 100mph on highest tops.
Effect of wind on you?
Very difficult walking/skiing from lower slopes up, and any mobility often tortuous on higher areas. Extreme wind chill..
Extensive heavy snowfall; hail, risk thunder
Snow, often heavy, which together with blowing snow will give sustained whiteout. Least precipitation southernmost Cairngorms NP (north of Glen Garry). However, there may be one or two breaks in the precipitation over a few hours - but snow may well return very suddenly.
Cloud on the hills?
Few glimpses of the summits (mostly likely only southern summits in Cairngorms NP); but cloud extensive above 600 to 900m lowest north, and intermittently below 400-600m, particularly Cairngorms and Lochnagar.
Chance of cloud free Munros?
Less than 10%
Sunshine and air clarity?
Sunshine very unlikely. Visibility widely near zero across higher areas; particularly Cairngorms.
How Cold? (at 900m)
Typically -3C; will tend to drop. Will feel as cold as minus 24 Celsius directly in the wind.
500m but will tend to drop through the day.
All mountain areas of Britain from Sunday 1st February 2015
Cold throughout the coming week with snow substantially remaining in place on the mountains and most terrain remaining frozen. By Tuesday or Wednesday substantially fine with winds easing markedly, although later in the week one or two temporary deteriorations, most extensively across the Scottish Highlands as weakening fronts bring temporarily stronger winds and snow (rain lower western areas).
