Mountain weather
North Grampian Mountain weather forecast table
Confidence
Generally high confidence for unsettled conditions and milder temperatures from Wednesday to Friday. Lower confidence in the timing and nature of the rain on Sunday.
This evening forecast
A dry evening with plenty of clear spells, starting to turn a bit cloudier towards midnight. Moderate, but strong on highest peaks, southerly winds. Cold with a risk of 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.
Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
Mountain weather forecast
Cloud and outbreaks of patchy rain spreading eastwards with widespread hill fog. Cold with significant wind chill in strong winds.

Additional weather information
Met Office Aberdeen meteorologist's view
A rather cloudy day with frequent hill fog giving very poor contrast in whiteout conditions above the snowline. Note rising freezing level resulting in thawing of the snowpack.
Weather
Mostly dry, cloudy and cold through the first half of the morning before rain and drizzle spreads eastwards. The afternoon will be cloudy with patchy rain and drizzle, some longer dry spells in the evening. Strong southerly winds with the risk of gales on the highest peaks. A risk of severe wind chill, this most significant through the first half of the day.
Chance of cloud-free hill tops
70% chance for a time early morning but becoming nil through the morning.
Low cloud and visibility
Occasional cloud bases down to around 1000m through the early hours but bases soon falling through the morning as cloud thickens with the arrival of rain with bases 400-600m, but bases may fall as low as 200m at times. Visibility good outside of cloud but moderate in rain and very poor in low cloud and hill fog.
