Lochnagar weather forecast.

A wild day on Lochnagar: summit wind broadly 15-40 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 1000-1600 m - the top is likely to drift in and out of cloud, with the best chance of a view from the morning into the evening. Cloud will be lowest on the NW slopes, down to about 1400-1700 m; the SE side should be clearer, lifting to around 1600-1900 m. Little or no rain expected. Cold on top: air temperature broadly 0 to 4°C, feeling around -6 to -2°C in the wind - wrap up. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 29-40 mph, so treat the headline as mid-range.

A rough, clagged-in day on Lochnagar: summit wind broadly 40-60 mph, with gusts 75-85 mph during the afternoon (storm-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base 700-1100 m - expect clag for much of the day, though a brief clearance is possible early in the morning. Cloud will be lowest on the W slopes, down to about 900-1200 m; the E side should be clearer, lifting to around 1200-1500 m. 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. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 48-65 mph, so treat the headline as mid-range.

A wild day on Lochnagar: summit wind broadly 45-65 mph, with gusts 75-85 mph early in the morning (storm-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base 900-2000 m - the top is likely to drift in and out of cloud, with the best chance of a view from late afternoon 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 SW slopes, down to about 1100-1400 m; the NE side should be clearer, lifting to around 1400-1700 m. Little or no rain expected. Cold on top: air temperature broadly 6 to 10°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 44-66 mph, so treat the headline as mid-range.

A wild day on Lochnagar: summit wind broadly 25-60 mph, with gusts 70-80 mph early in the morning (storm-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud will be lowest on the W slopes, down to about 1400-1700 m; the E side should be clearer, lifting to around 1500-1800 m. Little or no rain expected. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 39-64 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.

A fine day on Lochnagar: summit wind broadly 5-25 mph, with gusts 15-25 mph early in the morning (fresh and blowy). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1400-1700 m) - clear summits. 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. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 9 to 28 mph; check again nearer the time.

A mixed day on Lochnagar: summit wind broadly 15-35 mph, with gusts 35-45 mph during the evening (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base 800-1400 m - the top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 14 to 41 mph; check again nearer the time.

A rough, clagged-in day on Lochnagar: summit wind broadly 35-50 mph, with gusts 55-65 mph during the morning (storm-force winds).
