A mixed day on Creag Mhòr: summit wind broadly 5-25 mph, with gusts 25-35 mph early in the morning (fresh and blowy). The ground is likely to be wet after recent rain. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 500-800 m in the morning, lifting to 1500-1800 m around midday and 1500-1800 m by late afternoon. The top is likely to drift in and out of cloud; views may come and go. 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 2 to 6°C, feeling around -2 to 2°C in the wind - wrap up.

A rough, clagged-in day on Creag Mhòr: summit wind broadly 30-45 mph, with gusts 50-60 mph during the evening (storm-force winds). The ground is likely to be wet after recent rain.

Cloud base around 3000-3300 m in the morning, lowering to 700-1000 m around midday and 700-1000 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during the morning.

A mixed day on Creag Mhòr: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). Cloud base around 500-800 m in the morning, lifting to 800-1100 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 late afternoon into the evening.

Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 8 to 19 mph; check again nearer the time. 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.
