High confidence
Wind32 mph NW Gusts45 mph Feels2°C Rain0.0 mm Cloud base1,065 m Freezing level2,100 m

A wild day on Great Rigg: summit wind broadly 20-35 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 500-1600 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 NW slopes, down to about 900-1200 m; the SE side should be clearer, lifting to around 1100-1400 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.

A mixed day on Great Rigg: summit wind broadly 15-30 mph, with gusts 25-35 mph during the afternoon (strong 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 900-1200 m; the E side should be clearer, lifting to around 1100-1400 m. Little or no rain expected.

Wind27 mph SW Gusts38 mph Feels7°C Rain0.0 mm Cloud base815 m Freezing level3,180 m

A mixed day on Great Rigg: summit wind broadly 20-30 mph, with gusts 35-45 mph during the evening (strong winds). 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 evening. Little or no rain expected. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 21-31 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

A mixed day on Great Rigg: summit wind broadly 15-30 mph, with gusts 35-45 mph during the morning (strong 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 late afternoon into the evening. Cloud will be lowest on the W slopes, down to about 700-1000 m; the E side should be clearer, lifting to around 800-1100 m. Little or no rain expected. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 16 to 36 mph; check again nearer the time.

A mixed day on Great Rigg: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). Cloud base 500-1600 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. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. 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 9 to 23 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 mixed day on Great Rigg: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 1000-1300 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 15 to 39 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.
