High confidence
Wind24 mph W Gusts34 mph Feels-1°C Rain0.1 mm Cloud base1,027 m Freezing level1,900 m

A mixed day on Aonach Shasuinn: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 700-1600 m - the top is likely to drift in and out of cloud, with the best chance of a view from the morning into the afternoon. 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 -2 to 2°C in the wind - wrap up.

A rough, clagged-in day on Aonach Shasuinn: summit wind broadly 35-50 mph, with gusts 60-70 mph around midday (storm-force winds). 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. Cloud will be lowest on the SW slopes, down to about 400-700 m; the NE side should be clearer, lifting to around 800-1100 m. A persistently wet day is possible, with around 20-40 mm indicated; local totals could vary considerably. Cold on top: air temperature broadly 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 29 to 58 mph; check again nearer the time.

A wild day on Aonach Shasuinn: summit wind broadly 20-40 mph, with gusts 45-55 mph early in the morning (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base 700-1000 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. Cloud will be lowest on the W slopes, down to about 800-1100 m; the E side should be clearer, lifting to around 1100-1400 m. Some rain is likely, with around 2-5 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. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 27-48 mph, so treat the headline as mid-range.

Low confidence

A mixed day on Aonach Shasuinn: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). Cloud base 700-1700 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. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 6 to 20 mph; check again nearer the time.

Wind22 mph S Gusts30 mph Feels6°C Rain0.0 mm Cloud base3,102 m Freezing level2,250 m

A mixed day on Aonach Shasuinn: summit wind broadly 10-25 mph, with gusts 25-35 mph during the evening (strong winds). Much calmer lower down - generally 0-5 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1500-3200 m) - clear summits. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 10 to 39 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.
