A grey, cloudy day on Ysgafell Wen: summit wind broadly 15-30 mph, with gusts 25-35 mph early in the morning (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base 600-1100 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. 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. Little or no rain expected.

A fine day on Ysgafell Wen: summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (fresh and blowy). Any cloud sits well above the tops (base 1200-3200 m) - clear summits. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 15-26 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 Ysgafell Wen: summit wind broadly 5-25 mph, with gusts 20-30 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 1600-3100 m) - clear summits. Little or no rain expected. Bright spells with UV up to 6 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 13 to 29 mph; check again nearer the time. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.

A fine day on Ysgafell Wen: summit wind broadly 0-15 mph, with gusts 5-15 mph during the morning (a moderate breeze). Cloud base 500-1700 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. 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 6 - sunscreen on exposed skin. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 5 to 12 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.
