A rough, clagged-in day on Sgùrr a' Mhuilinn: summit wind broadly 5-15 mph, with gusts 10-20 mph during the evening (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. There could be a spate risk based on forecast rainfall.

Expect the top to stay in cloud for most or all of daylight, with no dependable break. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. 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.

A grey, cloudy day on Sgùrr a' Mhuilinn: summit wind broadly 10-35 mph, with gusts 40-50 mph during the evening (gale-force winds). The ground is likely to be wet after recent rain.

Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with around 5-10 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 17-37 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 17-37 mph, so treat the headline as mid-range.
