Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on northern slopes; the southern 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.

Cloud base around 400–700 m in the morning, then around 1300–1600 m around midday and 400–700 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from the morning into the afternoon. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.

Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.

A mixed day on Meallach Mhòr: summit wind broadly 0-15 mph, with gusts 10-20 mph during the afternoon (a moderate breeze). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Cloud base around 400–700 m in the morning, lifting to 800–1100 m around midday and 1300–1600 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. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. 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.

Forecast confidence: Forecast models disagree on whether meaningful rain reaches the hills during 10:00-16:00.

Cloud-free timing: Around 0% early, improving to around 60% later.

A grey, cloudy day on Meallach Mhòr: summit wind broadly 5-30 mph, with gusts 25-35 mph during the evening (strong winds). Cloud base around 500–800 m through the morning, lifting to 900–1200 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during 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 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 13-33 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 13-33 mph, so treat the headline as mid-range.
