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.

A rough, clagged-in day on Blà Bheinn: summit wind broadly 10-40 mph, with gusts 40-50 mph during the evening (gale-force winds).

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. 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 25-45 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 25 to 45 mph; check again nearer the time.
