A wild day on Càrn Chuinneag: summit wind broadly 15-35 mph, with gusts 40-50 mph early in the morning (gale-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 800-1500 m - the top is likely to drift in and out of cloud, with the best chance of a view from the morning into the evening. The cloud base is very changeable today - it could sit much higher or lower than that at times, so read the sky. Cloud will be lowest on the W slopes, down to about 900-1200 m; the E side should be clearer, lifting to around 1100-1400 m. Little or no rain expected. Cold on top: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind - wrap up.

Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base 500-800 m - expect the top to stay in cloud for most or all of the day, with no dependable break.

Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 30-59 mph, so treat the headline as mid-range.

A wild day on Càrn Chuinneag: summit wind broadly 30-50 mph, with gusts 55-65 mph early in the morning (storm-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops.

Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 32-55 mph, so treat the headline as mid-range. 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.
