Medium confidence
Wind33 mph W Gusts46 mph Feels-3°C Rain2.2 mm Cloud base806 m Freezing level2,000 m

A rough, clagged-in day on Conival: summit wind broadly 20-40 mph, with gusts 40-50 mph during the evening (gale-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 500-1100 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. Cloud will be lowest on the W slopes, down to about 700-1000 m; the E side should be clearer, lifting to around 900-1200 m. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Cold on top: air temperature broadly 2 to 6°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 26-39 mph, so treat the headline as mid-range.

A rough, clagged-in day on Conival: summit wind broadly 50-60 mph, with gusts 75-85 mph during the evening (storm-force winds). Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Cloud base 400-700 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 300-600 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 4 to 8°C, feeling around -4 to 0°C in the wind - wrap up. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 44-64 mph, so treat the headline as mid-range.

A grey, cloudy day on Conival: summit wind broadly 5-30 mph, with gusts 25-35 mph early in the morning (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base 500-900 m - expect clag for much of the day, though a brief clearance is possible early in the morning. 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. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 10 to 39 mph; check again nearer the time.

A mixed day on Conival: summit wind broadly 10-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base 600-3200 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 15 to 36 mph; check again nearer the time.

A wild day on Conival: summit wind broadly 25-40 mph, with gusts 45-55 mph around midday (gale-force winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 700-1500 m - the top is likely to drift in and out of cloud, with the best chance of a view from early 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 SW slopes, down to about 600-900 m; the NE side should be clearer, lifting to around 900-1200 m. 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 18 to 60 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.
