A rough, clagged-in day on Lurg 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. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 00:00 until around 20:00. Cloud base around 400–700 m through the morning, lifting to 800–1100 m by late afternoon. Expect clag for much of the day, though a brief clearance is possible during the afternoon. A persistently wet day is possible, with around 5-10 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: Thunderstorm timing is inherently uncertain and may shift by several hours.

A rough, clagged-in day on Lurg Mhòr: summit wind broadly 10-35 mph, with gusts 40-50 mph during the evening (gale-force winds). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 08:00 until around 23:00. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base mostly around 400–700 m through daylight. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on western slopes; the eastern side should see somewhat higher bases and better breaks. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Cold on top: air temperature broadly 4 to 8°C, feeling around 0 to 4°C in the wind - wrap up. Confidence moderate (Summit wind could be roughly 18-39 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 18-39 mph, so treat the headline as mid-range.
