A fine day on Moel yr Henfaes: summit wind broadly 10-25 mph, with gusts 25-35 mph during the morning (fresh and blowy). Any cloud sits well above the tops (base 1700-2000 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 17-23 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.
