High for settled conditions, with risk of morning fogs, but otherwise clearing to sunshine. Fog clearance detail low confidence throughout.
A band of rain is expected to die out in situ, leaving a legacy of widespread low cloud and some valley mist and fog. Winds easing towards midnight.
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.
Chilly with extensive low cloud and fog during the morning. Mild in valleys with sunshine later.

A murky start, with extensive low cloud and valley mist and fog that should prove slow to clear in the east, with western slopes perhaps clear by mid-morning. Otherwise, conditions should improve to a fine day with plenty of sunshine, albeit perhaps a little hazy through high cloud. It will be very mild for February, especially in shelter although the southwesterly breeze at height may make it feel nearer mid-single figures degrees Celsius. Mist and eventually fog should reform in valleys during the evening, requiring caution from late descenders.
Perhaps 40% in the west at first, with valley fog and broken cloud around 800m. Chances generally improving to 90% by the afternoon, improving latest in the east.
Poor or very poor at first in valleys and near the higher summits, but improving to generally good by lunchtime. Deteoriating at low level into the evening as fog reforms.
While mild for February, the breeze in exposure at height may make it feel nearer mid-single figure degrees Celsius.

Fine with sunshine after early fog clears, with this expected to occur more readily than on Sunday, perhaps by mid-morning, with the east and north improving first. Mist and fog will reform during the evening in valleys, with care advised for late descents.
90% throughout, although note low level fog.
Poor in valleys at first and during the evening, otherwise improving to very good.
