from late afternoon into the evening. Leave exposed summits and ridges if thunder develops.
Cloud-free timing: Around 0% early, improving to around 40% later.
A grey, cloudy day on The Cobbler: summit wind broadly 20-35 mph, with gusts 40-50 mph early in the morning (gale-force winds). Thunderstorms are possible from late afternoon into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 500–800 m in the morning, then around 1000–1300 m around midday and 700–1000 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from midday into the afternoon. Cloud is likely to hang lowest on eastern slopes; the western side should see somewhat higher bases and better breaks. Little or no rain expected.
