A fine day on Tarrenhendre: summit wind broadly 5-20 mph, with gusts 20-30 mph during the morning (fresh and blowy). Any cloud sits well above the tops (base 1200-1800 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 12-22 mph, so treat the headline as mid-range. Treat the cloud base with caution - the models disagree on humidity, so it could be well above or below the figure given.

A fine day on Tarrenhendre: summit wind broadly 5-15 mph, with gusts 10-20 mph during the evening (a moderate breeze). Any cloud sits well above the tops (base 900-1400 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 7 to 17 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.
