High for east to southeasterly flow holding sway through the coming days and for wintry precipitation being confined to Wednesday. Medium for the extent and timing of the showers within the flow. Low regarding cloud amounts in the weekend.
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 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 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.
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.
Winter conditions at height at first, with persistent, and occasionally heavy snow above 400m. Rain and sleet to lower levels. This clearing through the day, but hills likely remaining obscured.

Winter conditions at first on even modest tops, with frequent and occasionally heavy snow above 400m, with some sleet or temporary snow to lower levels. However this will ease through the morning, with any snow restricted to above 600m, and largely dry conditions developing into the afternoon. Despite that, it will stay rather cold, with brisk winds.
20% at first with cloud obscuring tops above 500m, perhaps down to 300m in the east. These lifting and breaking into afternoon, to become 80% by mid-afternoon, with broken cloud around 700m. Becoming near 100% by midnight.
Very poor to poor at first, especially on the tops during snowfall. Visibilities improving into the afternoon, with moderately distant hills likely becoming visible as dry conditions develop and cloud lifts.
Wintry on the tops, with paths and rocks likely covered on summits. Good navigation skills in winter conditions essential for those heading onto the summits during the morning. Whilst conditions will improve, the ground on the tops will remain frozen throughout, with some summits remaining obscured until the evening. Feeling cold, with warm layers required.

A period of clear skies during the early hours, could lead to some mist and valley fog, whilst hills will freeze. However higher freezing levels will spread in from the east during the morning, leading to a thaw at all levels. This will be accompanied by some extensive cloud, and outbreaks of rain or drizzle, which could persist for much for the day.
Southeasterly 25mph with gusts 35mph.
Falling to around 40% in the east and 70% in the west by dawn with cloud around 500m spreading in from the east. This becoming extensive during the afternoon, with chances falling to 20% for all hills.
Good views at first, for many hills, especially in the west. But falling to moderate, perhaps poor at times during outbreaks of rain or drizzle later.
