Additional weather information
Met Office Aberdeen meteorologist's view
Gusts of over 40mph will give difficult walking conditions with a risk of being blown off balance. Combined with blowing snow showers, navigation will be challenging with energy output significantly increased when walking into the wind. Lying snow or ice will mean suitable footwear is advised. Keep up to date with the latest forecast from the Scottish Avalanche Information Service.
Weather
Thursday evening's rain will clear shortly after midnight allowing conditions to become dry with clear spells through the early hours. Clear or bright spells and the odd shower in the morning, these wintry above 600m. These become more frequent through the afternoon and evening as the freezing level falls, bringing snow down to 300m, with a chance of lightning later in the day. Strengthening winds with a chance of summit gales later.
Chance of cloud-free hill tops
70% in the morning, 40% later.
Low cloud and visibility
Clear periods with good visibilities at times, but cloud bases falling to 600-800m and visibilities rapidly falling poor as showers pass through.
