Meteorologist's view
A pleasant day with winds lighter than of recent days, but still feeling rather chilly at height.
Weather
The odd light wintry shower in the early hours. Otherwise a largely dry day with sunny spells in the morning once early patches of hill fog lift above summits. Turning widely cloudier during the afternoon, with light rain and hill fog spreading in from the west by evening, the rain falling as snow on highest summits.
Chance of cloud-free hill tops
60% rising to 90%. Decreasing to 30% in the evening.
Low cloud and visibility
A few patches of low cloud above 1000m early morning, quickly lifting above all summits. Low cloud above 800m returns in the evening. Outside of hill fog visibility will be generally excellent.
Ground conditions
No recent ground conditions report available.
