Wind25 mph W Gusts32 mph Feels0°C Rain1.1 mm Cloud base603 m Freezing level1,880 m

A grey, cloudy day on Askival: summit wind broadly 15-30 mph, with gusts 25-35 mph early in the morning (strong winds). Cloud base 500-900 m - the top is likely to drift in and out of cloud, with the best chance of a view early in the morning. Cloud will be lowest on the W slopes, down to about 500-800 m; the E side should be clearer, lifting to around 700-1000 m. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain. 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 Askival: summit wind broadly 45-60 mph, with gusts 70-80 mph during the evening (storm-force winds). Much calmer lower down - generally 30-40 mph in the valley, rising towards the tops. Cloud base 500-800 m - expect clag for much of the day, though a brief clearance is possible early in the morning. 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 5-10 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.

A rough, clagged-in day on Askival: summit wind broadly 40-60 mph, with gusts 65-75 mph early in the morning (storm-force winds). Much calmer lower down - generally 30-40 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 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.

Medium confidence
Wind37 mph W Gusts47 mph Feels2°C Rain0.4 mm Cloud base946 m Freezing level10,000 m

A wild day on Askival: summit wind broadly 20-40 mph, with gusts 40-50 mph early in the morning (gale-force winds). Much calmer lower down - generally 15-25 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 400-1000 m) - clear summits. Cloud will be lowest on the W slopes, down to about 800-1100 m; the E side should be clearer, lifting to around 1000-1300 m. Little or no rain expected. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 28-48 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.

Low confidence
Wind9 mph N Gusts13 mph Feels4°C Rain0.0 mm Cloud base579 m Freezing level10,000 m

A mixed day on Askival: summit wind broadly 0-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). Cloud base 500-800 m - the top is likely to drift in and out of cloud, with the best chance of a view from midday into the afternoon. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 5 to 16 mph; check again nearer the time.

Low confidence
Wind35 mph S Gusts41 mph Feels8°C Rain0.0 mm Cloud base1,530 m Freezing level10,000 m

A mixed day on Askival: summit wind broadly 20-40 mph, with gusts 35-45 mph during the evening (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base 500-2100 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. Little or no rain expected. Bright spells with UV up to 5 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 18 to 57 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.

A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 18 to 61 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.
