A mixed day on Beinn Mholach: summit wind broadly 10-25 mph, with gusts 25-35 mph during the morning (fresh and blowy). 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 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 4 to 8°C, feeling around -2 to 2°C in the wind - wrap up.

A rough, clagged-in day on Beinn Mholach: summit wind broadly 30-50 mph, with gusts 60-70 mph during the evening (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 10-20 mm indicated; local totals could vary considerably. 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 32-55 mph, so treat the headline as mid-range.

A wild day on Beinn Mholach: 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 500-1500 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 1300-1600 m; the E side should be clearer, lifting to around 1600-1900 m. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 25-45 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.
