Cloud-free timing: Around 0% early, improving to around 100% later.

A mixed day on White Coomb: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). The ground is likely to be wet after recent rain. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 600-900 m in the morning, lifting to 800-1100 m around midday and 1500-1800 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Cloud is likely to hang lowest on northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. Little or no rain expected. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up.

A wild day on White Coomb: summit wind broadly 20-35 mph, with gusts 40-50 mph during the morning (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 600-900 m in the morning, lifting to 1000-1300 m around midday and 1000-1300 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the morning into the evening. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Little or no rain expected. Cloud base is the least certain part of this - the models are only moderately agreed, so it could sit a couple of hundred metres either way.
