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

Thunder risk: likely

Cloud-free timing: Cloudier around midday at about 0%; around 67% early and 80% later.

A wild day on Craig-las: summit wind broadly 10-30 mph, with gusts 30-40 mph early in the morning (strong winds). Thunderstorms are forecast from the morning into the evening. Avoid exposed summits and ridges during the risk period. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 700–1000 m in the morning, then around 500–800 m around midday and 700–1000 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from late afternoon into the evening. Cloud is likely to hang lowest on southeastern slopes; the northwestern side should see somewhat higher bases and better breaks. A persistently wet day is possible, with around 5-10 mm indicated; local totals could vary considerably.

A rough, clagged-in day on Craig-las: summit wind broadly 10-30 mph, with gusts 25-35 mph during the morning (strong winds). Thunderstorms are forecast from late afternoon into the evening. Avoid exposed summits and ridges during the risk period. 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 03:00 the following day. 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. A persistently wet day is possible, with around 10-20 mm indicated; local totals could vary considerably. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 18-27 mph, so treat the headline as mid-range.
