Stob Coire a' Chearcaill weather forecast.

Cloud-free timing: Around 100% early, falling to around 80% later.

A mixed day on Stob Coire a' Chearcaill: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (strong winds). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 900-1500 m) - clear summits. Little or no rain expected.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

A grey, cloudy day on Stob Coire a' Chearcaill: summit wind broadly 10-25 mph, with gusts 25-35 mph early in the morning (strong winds). Thunderstorms are possible from around midday into the evening. Keep an escape route from exposed ridges and descend if thunder develops. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, then around 600–900 m around midday and 400–700 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Some rain is likely, with around 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 17-26 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 7 hours on when it arrives.

Cloud-free timing: Around 0% early, improving to around 100% later.

A mixed day on Stob Coire a' Chearcaill: summit wind broadly 0-15 mph, with gusts 5-15 mph during the evening (a moderate breeze). Cloud base around 400–700 m in the morning, lifting to 600–900 m around midday and 1800–2100 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. Little or no rain expected. 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.

Cloud-free timing: Around 0% early, improving to around 100% later.

A rough, clagged-in day on Stob Coire a' Chearcaill: summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (fresh and blowy). A meaningful thunderstorm risk is indicated from the morning into the evening. Avoid committing to exposed ridges if storms begin to build. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 300–600 m in the morning, lifting to 400–700 m around midday and 800–1100 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 southern slopes; the northern 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. Confidence moderate (Summit wind could be roughly 14-29 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 14-29 mph, so treat the headline as mid-range.

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

A rough, clagged-in day on Stob Coire a' Chearcaill: summit wind broadly 15-50 mph, with gusts 60-70 mph during the evening (storm-force winds). A meaningful thunderstorm risk is indicated from early 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 03:00 the following day. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 300–600 m in the morning, then around 500–800 m around midday and 300–600 m by late afternoon. Expect the top to stay in cloud for most or all of daylight, with no dependable break. Cloud is likely to hang lowest on southwestern slopes; the northeastern 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 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Low confidence (Summit wind could be roughly 24-60 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 24 to 60 mph; check again nearer the time.

Forecast confidence: A low thunderstorm risk remains difficult to time precisely.

Cloud-free timing: Around 0% early, improving to around 100% later.

A grey, cloudy day on Stob Coire a' Chearcaill: summit wind broadly 15-30 mph, with gusts 35-45 mph around midday (strong winds). Thunderstorms are possible from the morning into the afternoon. Keep an escape route from exposed ridges and descend if thunder develops. The ground is likely to be wet after recent rain. Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, lifting to 700–1000 m around midday and 1000–1300 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 northwestern slopes; the southeastern 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. 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.
