High confidence for a southwesterly airflow for several days, but medium confidence for timings and amounts of rain.
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.
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.
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Dry, bright start, but cloudier by the afternoon with a spell of drizzly rain, but clearing later with clear spells.

A dry and bright start with some sunshine, but cloud will build towards midday with a spell of drizzly rain around midday, then clearing before dusk.
Patchy cloud above the tops on Sunday morning, but chance reducing to 30% around midday with broken cloud around 500m, perhaps 400 m in drizzle.
Mainly good, but misty beneath cloud into the afternoon, and falling moderate or poor at times in rain.
A windy morning with gales 35mph gusts 45 mph over higher slopes and exposed ridges and summits, easing slightly later.
