High for easterly flow holding sway through the coming days and for wintry precipitation being largely confined to the very highest peaks from Thursday. Medium for the extent and timing of the showers within the flow.
Showers merging to longer periods of rain and summit snow towards late evening, with hill fog becoming extensive, combining with gales over the summits and a severe chill effect to bring some hazardous conditions.
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.
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.
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.
Very difficult conditions initially with periods of rain and summits snow, hill fog and gales at height, but improving from early morning.

Some hazardous conditions at first with periods of rain and sleet, falling as snow from around 450-600m, with cloud bases extensive and covering most summits, particularly across eastern ranges. Conditions look set to improve from early morning with outbreaks dwindling to a few well scattered showers by mid to late morning, with most staying dry and seeing the weak sunny spells increasing through the afternoon. Staying largely dry and clear for the evening.
Initially 20% in east and 40% in west with bases extensive from around 550m and 750m respectively, with patches lower across eastern aspects. Increasing from early morning becoming 90% by mid-afternoon as the cloud lifts and breaks.
Moderate or poor at first, occasionally very poor in wintry precipitation, becoming good or very good by early afternoon.
Some hazardous conditions initially with blizzards over the higher peaks. Conditions improving from early morning, but chill effect continuing at height.
No recent ground conditions report available.
Showers spreading for the east overnight, and continuing through the day and evening. The bulk of these will be focused over the eastern peaks, falling as rain at all levels, but perhaps turning sleety at times across Scafell Pike.
East to Southeast mean speed initially 45-50mph over the highest peaks with gusts reaching 60-65mph, easing slightly from mid-morning.
90% at first, falling by mid-morning to 25% across eastern peaks and 60% for western peaks as bases lower to 550m and 850m respectively.
Good or very good becoming moderate or poor in showers.
