High confidence for the general weather until Wednesday. Low confidence from Wednesday onwards for position of rain band over the UK.
A dry evening with clear spells and light winds. Patchy fog will develop in the valleys, mainly western side of the Yorkshire Dales.
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.
Prolonged exposure to heavy rain can result in drenched clothing and a risk of hypothermia if not wearing good quality waterproofs. Terrain may turn increasingly boggy underfoot, while mountain streams will rapidly rise into spate and may become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.
Progress will be impeded by very strong winds. Walking will be difficult and strenuous at times with a potential for one to be blown over in gusts. There can be a marked increase in winds through cols or on exposed ridges and summits. Distances often take longer to cover with compass bearings becoming more difficult 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.
Winds strengthening with low cloud and rain.

Dry overnight with some fog in the valleys. Outbreaks of rain will arrive during the morning and will become heavy for a time. Rain turning drizzly in the afternoon then clearing soon after dark with clear spells and patchy valley fog developing.
40% overnight but becoming almost nil during the morning with cloud bases descending to around 300 or 400m. Becoming 70% in the evening with cloud turning patchy and clearing most summits.
Patchy fog in the valleys and on some developing on higher slopes overnight. Turning poor during the morning with low cloud and rain or drizzle. Improving through the evening once rain clears.
Winds across some of the highest summits will gust 45mph at times during the day.

Staying dry with bright or sunny spells during the day, thick cirrus cloud will invade from the west at times. Patchy fog in the valleys and on low slopes will be slow to clear in places and will develop again in the evening.
West 15mph in early hours but mainly South or SW 5-10mph.
Good chance of clear summits for much the day but with some patches of cloud on low slopes and in the valleys.
Very poor in some of the glens where fog lingers, otherwise good.
