Mountain weather
North Grampian Mountain weather forecast table
Confidence
High confidence for colder conditions to continue until Wednesday when there will be a period of very mild conditions, turning colder again by Friday. Further snow accumulations expected on Monday as freezing level falls and showers continue. Milder conditions mid week will cause some melting of the snowpack.
This evening forecast
Rain, sleet and snow is expected for the evening period, freezing level will be around 900m, a few clearer spells developing by late evening, strong northeasterly winds and a severe wind chill.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Severe Chill Effect
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.
Poor Visibility
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.
Blizzards
Blizzards and whiteouts present challenging and serious conditions due to a combination of falling or blowing snow, strong winds and cold temperatures. They can be highly disorientating, often resulting in near-zero visibility with limited or no visual references and no distinction between ground and sky. Cliff edges and cornices may not be apparent, even close up. These conditions require very good navigational skills.
Mountain weather forecast
Turning wintry again with wintry showers for the Northern Cairngorms, drier and brighter further west, bitterly cold in strong northeasterly winds.

Additional weather information
Met Office Aberdeen meteorologist's view
Turning colder during the day as freezing level falls, bitterly cold in wintry showers during the morning with significant windchill, progress will be tricky at higher levels with further snow accumulations expected, strong northerly winds will cause some drifting and blizzards.
Weather
A cloudy day with frequent snow showers for more northern and Eastern ranges, further west there will be brighter and drier conditions. Showers frequent in the east in the morning but becoming more isolated during the afternoon with some brighter spells developing. Accompanied by strong winds there may be blizzard conditions at times for the higher northern Cairngorms. Freezing level lowering from 1100m to 700m, showers turning increasingly wintry during the morning.
Chance of cloud-free hill tops
50%, greater chance further south and west, improving to 70% in the afternoon.
Low cloud and visibility
Scattered or broken layers of cloud above 500m during the morning, perhaps more overcast for the Northern Cairngorms, cloud tending to be patchier further west towards Loch Ossian where less showers are likely. During the afternoon cloud becoming patchier with more chance of clear summits out with showers. Visibility will be poor or very poor in the morning for the Northern Cairngorms and summits in the east but will improve steadily during the day with good periods in the afternoon.
