A mixed day on Sgiath Chùil: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (strong winds). The ground is likely to be saturated after recent rain. Expect boggy paths and rapid runoff if more rain arrives. Much calmer lower down - generally 5-15 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 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up.

A rough, clagged-in day on Sgiath Chùil: summit wind broadly 25-40 mph, with gusts 45-55 mph during the evening (gale-force winds). The ground is likely to be saturated after recent rain.

Expect clag for much of the day, though a brief clearance is possible during the evening. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 5-10 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 19 to 41 mph; check again nearer the time.

A grey, cloudy day on Sgiath Chùil: summit wind broadly 20-35 mph, with gusts 35-45 mph during the evening (gale-force winds). A meaningful thunderstorm risk is indicated from the afternoon into overnight. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 800-1100 m in the morning, lowering to 800-1100 m around midday and 500-800 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible early in the morning. Cloud is likely to hang lowest on southern slopes; the northern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 15 to 53 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.
