A fine day on Sgòr Mòr: summit wind broadly 5-25 mph, with gusts 20-30 mph early in the morning (fresh and blowy). The ground is likely to be wet after recent rain. Cloud base around 700-1000 m in the morning, lifting to 1300-1600 m around midday and 1500-1800 m by late afternoon. The top is likely to drift in and out of cloud; views may come and go. Cloud is likely to hang lowest on northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. Little or no rain expected. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (ensemble members show a moderate spread) - the summit peak could reasonably be 16-23 mph, so treat the headline as mid-range.
