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. Cold on top: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind - wrap up.

Wind12 mph NW Gusts16 mph Feels3°C Rain0.3 mm Cloud base1,306 m Freezing level10,000 m

A fine day on Streap: summit wind broadly 5-15 mph, with gusts 10-20 mph early in the morning (a moderate breeze). Cloud base 800-1600 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. Low confidence (ensemble members are widely spread) - the summit peak could be anywhere from 6 to 21 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 Streap: summit wind broadly 15-30 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. Any cloud sits well above the tops (base 1500-3200 m) - clear summits. 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 16 to 42 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.
