Additional weather information
Meteorologist's view
Unpleasant conditions at first and feeling bitterly cold with frequent heavy showers and widespread strong winds giving difficult walking conditions with a risk of being blown off balance, whilst navigation could be challenging with energy output significantly increased when walking into the wind. Much better conditions in the afternoon but still quite chilly.
Weather
Frequent heavy showers in the early morning with a very small chance of hail and lightning, accompanied by gales with a chance of storm-force gusts over the highest summits. Showers and strong winds gradually easing after dawn, becoming largely dry by midday and through the afternoon with sunny spells. Clouding over from the west in the evening with the chance of some patchy light rain shortly before midnight.
Chance of cloud-free hill tops
20% or less in early hours, rising to 40% by mid-morning, 70% from afternoon.
Low cloud and visibility
Quite widespread cloud down to 500-700m in the early morning with poor visibilities in hill fog and heavy rain. Cloud gradually lifting and breaking through the day with some clear spells developing but still patches of cloud around 900-1100m.
Ground conditions
