Cloud-free timing: Around 0% early, improving to around 100% later.
A mixed day on The Cheviot: summit wind broadly 10-25 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 around 500-800 m in the morning, lifting to 800-1100 m around midday and 1500-1800 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Cloud is likely to hang lowest on northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.
