High for the general weather story this week. Lower confidence for when the rain will clear east on Tuesday and for timings of rain arriving on Friday.
Mainly cloudy with showery rain, falling as sleet or snow above 700m, but becoming mainly dry late in the evening. Fresh southerly winds, about 20mph, gusting 30mph on the summits.
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.
Dry with sunny spells in morning, becoming windy with outbreaks of rain arriving in afternoon. Feeling cold.

Dry in the early hours with clear spells then Monday morning will be dry with bright or sunny spells. Clouding over in the afternoon with patchy rain arriving from the west. Rain perhaps heavy for a time in the evening, but staying mostly light and intermittent.
80% in the morning with a few patches of low cloud. Becoming 30% during the afternoon with extensive cloud developing, bases 500-700m.
Patchy early morning mist but otherwise good through the morning with excellent air clarity. Becoming poor at times from around mid-afternoon as rain and low cloud arrives.
A quiet morning of weather but note that conditions will become more hazardous from mid-afternoon onwards as winds strengthen bringing a significant wind chill.
No recent ground conditions report available.
Very windy with extremely challenging walking conditions on high ground. Patchy rain in early hours but rain will become heavy and persistent by dawn and last for most of the day to give drenching conditions. Heavy rain clears away to the east in the afternoon followed by clear intervals and scattered showers, wintry on summits.
Southerly average 50-60mph with gusts 80mph, easing through the afternoon to 20-30mph gusts 40mph.
Almost nil due to persistent cloud with bases 400-600m for most of the day. Becoming 70% through evening as cloud lifts and breaks up.
Poor for most of the day with low cloud at height and often a few km or less at low levels. Becoming clearer later as rain moves away east in the afternoon.
