High confidence for rain and low cloud to move in through Friday, leading to cooler conditions than recent days. High for fine, dry, conditions returning Saturday and Sunday, although moderate in cloud amounts. Moderate for cloudier, showery weather arriving Monday, but easing away Tuesday.
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.
Heavy and persistent rain can lead to drenched clothing and footwear with waterproofs often becoming soaked through, especially if accompanied by strong winds. This can lead to significant loss of body heat and an increased likelihood of hypothermia. Terrain may turn increasingly boggy underfoot while streams can flood and 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.
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 start, however rain arriving from the northwest and spreading across the Yorkshire Dales during the morning. Poor visibilities developing, with cloud obscuring tops, especially during heavy bursts later.

A dry start, however cloud will thicken through the morning as outbreaks of rain spread southeast. As the rain and drizzle moves in, cloud will descend onto the hilltops, leading to some poor visibility developing. Whilst rain is likely to become sporadic through the afternoon, there is the potential for one or two heavier bursts to develop, especially in the west. Rain will then ease during the evening, however cloud will persist across the tops.
80% at first, with only isolated patches of cloud on the summits. However this falling to 40% by midday, with cloud obscuring hills above 500m and some patches down to 300m in the north and west.
Good or very good until mid morning when visibility will fall to a few kilometres in the rain and less than a kilometre in any heavier bursts. Some very poor visibility likely on summits, and in any drizzle that occurs.
Feeling much cooler than of late with cloudy skies, and outbreaks of rain. Visibilities could also be very poor, especially on the tops, so a much different day to recent ones.

A cool and cloudy start is expected, with hilltops remaining shrouded until the late morning, and perhaps the odd patch of valley mist. Eventually the cloud will thin and break, allowing some warm sunny interludes to develop by the late afternoon. A fine end to the day is then expected with light winds.
30% at first with cloud persisting above 400m. This cloud thinning and lifting, to become 80% by midday, and near 100% by the afternoon as warm sunny intervals develop
Some moderate to poor visibilities in the morning, down to a few kilometres, but improving throughout. By the mid-afternoon, visibilities are likely to exceed 20km, with some distant hills visible.
