Cloud-free timing: Around 0% early, improving to around 100% later.

A mixed day on Illgill Head: summit wind broadly 15-35 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 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 western slopes; the eastern side should see somewhat higher bases and better breaks. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.

A fine day on Illgill Head: summit wind broadly 10-25 mph, with gusts 25-35 mph around midday (fresh and blowy). Any cloud sits well above the tops (base 600-1100 m) - clear summits. Little or no rain expected.

Cloud-free timing: Around 75% early, improving to around 100% later.

A fine day on Illgill Head: summit wind broadly 15-25 mph, with gusts 20-30 mph during the afternoon (fresh and blowy). Any cloud sits well above the tops (base 1100-3200 m) - clear summits. Little or no rain expected. Bright spells with UV up to 5 - sunscreen on exposed skin. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 13-23 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.

Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain.
