High confidence for general story but low confidence for any cloud breaks and timing of the rain on Sunday.
Low cloud and hill fog are likely to persist for the evening with some drizzly outbreaks overnight.
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.
Low cloud, rain and drizzle in the morning clearing by late afternoon.

An overcast morning with extensive low cloud producing some drizzle at times. More organised rain will form later in the morning with the odd heavy spell particularly on high ground. By late afternoon the rain will move south with cloud clearing in the evening and a clear night is expected later with temperatures likely to fall close to zero and frost forming in sheltered areas. Cloud will clear slightly later in the southern Lake District but some evening sun is a possibility.
In the morning 20% chance of cloud free tops but from lunchtime hill tops in the north will progressively clear with the southern tops like the Old Man of Coniston last to clear. By early evening 80% of tops will be clear.
Visibility below the cloud will be moderate but will become poor in drizzle or light rain, perhaps less than 1km in places, navigation will be difficult on hills for much of the day. Later visibility will improve from the north with good views by late afternoon.
A noticeable wind veer in the afternoon will mark the passing of the weather front and cloud will begin to break and clear after that. Temperatures will drop as the northwesterly airmass sets in with a marked windchill later in the day.
No recent ground conditions report available.
A clear start to the day with frost forming in many sheltered areas. Good sunny spells once the sun comes up but some cloud is expected to come and go during the day. Cloud is likely to thicken in the evening, particularly in the west with a dull end to the day and risk of a spot or two of rain.
Northwesterly 20 mph with gusts around 30mph at 800m, the winds will back westerly during the afternoon.
90% chance of cloud free tops. Some of the highest tops in the west may see some wisps of cloud by the evening.
Visibility will be excellent for much of the day with great views expected at height; visibility will reduce slightly in the evening as winds turn westerly but will still be better than 10km in most places.
