A grey, cloudy day on Caisteal Abhail: summit wind broadly 20-35 mph, with gusts 35-45 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. There could be a spate risk based on forecast rainfall. Burns and unbridged crossings may rise quickly. Most likely from around 02:00 until around 03:00 the following day. Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Cloud base around 400–700 m through the morning, lifting to 600–900 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view during the afternoon. Cloud is likely to hang lowest on southern slopes; the northern 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 22-42 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 22-42 mph, so treat the headline as mid-range.

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

A rough, clagged-in day on Caisteal Abhail: summit wind broadly 40-75 mph, with gusts 95-105 mph during the afternoon (storm-force winds). Thunderstorms are possible from early 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. 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 23:00. Much calmer lower down - generally 25-35 mph in the valley, rising towards the tops. Cloud base mostly around 300–600 m through daylight.

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 5-10 mm indicated; local totals could vary considerably. Cold on top: air temperature broadly 4 to 8°C, feeling around -4 to 0°C in the wind - wrap up. Low confidence (Summit wind could be roughly 54-86 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 54 to 86 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 40-61 mph, which changes how difficult exposed walking may feel.
