Additional weather information
Meteorologist's view
Navigation will be challenging with quite widespread areas of hill fog for much of the day. Moderate UV levels where the sun breaks through so suitable protection is advised. Turning quite breezy late in the day.
Weather
Dry in the early hours with areas of low cloud and valley mist or fog. Widespread cloud around summit height spreading through the morning thick enough to generate a few showers. Some limited bright or sunny spells may develop between cloud in the afternoon. Dry in the evening but cloud lowering onto slopes again.
Chance of cloud-free hill tops
20% or less in morning and evening. Rising to 70% by afternoon.
Low cloud and visibility
Quite widespread cloud below 500m in the early morning and again in the evening, or some mist or fog patches forming in sheltered glens. This cloud lifting to around 800-1000m during the day with some limited breaks at times, before lowering again in the evening. Visibilities falling poor in hill fog.
Ground conditions
No recent ground conditions report available.
