Corserine weather forecast.

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

Cloud-free timing: Best around midday at about 100%; around 67% early and 80% later.

A fine day on Corserine: summit wind broadly 10-30 mph, with gusts 25-35 mph early in the morning (fresh and blowy). Much calmer lower down - generally 0-10 mph in the valley, rising towards the tops. Any cloud sits well above the tops (base 900-1200 m) - clear summits. Little or no rain expected.

Forecast confidence: Forecast models disagree on whether meaningful rain reaches the hills during 10:00-16:00.

A grey, cloudy day on Corserine: summit wind broadly 10-30 mph, with gusts 30-40 mph during the evening (strong winds). High spate risk based on forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Most likely from around 00:00 until around 21:00. 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 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 (forecast models agree on the walking impact of the wind) - the summit peak could reasonably be 19-30 mph, so treat the headline as mid-range.

Forecast confidence: Rain is possible, but forecast models differ by about 8 hours on when it arrives.

Cloud-free timing: Around 0% early, improving to around 60% later.

A grey, cloudy day on Corserine: summit wind broadly 5-20 mph, with gusts 15-25 mph early in the morning (a moderate breeze). The ground is likely to be wet after recent rain. Cloud base around 400–700 m in the morning, lifting to 600–900 m around midday and 900–1200 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. Some rain is likely, with up to around 2 mm indicated; timing and local totals remain uncertain.

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

Cloud-free timing: Best around midday at about 75%; around 0% early and 0% later.

A grey, cloudy day on Corserine: summit wind broadly 15-35 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. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 400–700 m in the morning, then around 1300–1600 m around midday and 400–700 m by late afternoon. The top is likely to drift in and out of cloud, with the best chance of a view from midday into 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 2-5 mm indicated; timing and local totals remain uncertain. Confidence moderate (Summit wind could be roughly 24-38 mph, which changes how difficult exposed walking may feel) - the summit peak could reasonably be 24-38 mph, so treat the headline as mid-range.

Forecast confidence: Summit wind could be roughly 41-70 mph, which changes how difficult exposed walking may feel.

A rough, clagged-in day on Corserine: summit wind broadly 40-65 mph, with gusts 75-85 mph during the afternoon (storm-force winds). 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 03:00 the following day. Much calmer lower down - generally 15-25 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 -4 to 0°C in the wind - wrap up. Low confidence (Summit wind could be roughly 41-70 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 41 to 70 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 37-56 mph, which changes how difficult exposed walking may feel.

A rough, clagged-in day on Corserine: summit wind broadly 35-55 mph, with gusts 65-75 mph around midday (storm-force winds). The ground is likely to be wet after recent rain. High spate risk based on forecast rainfall. Burns and unbridged crossings may become difficult or impassable. Most likely from around 00:00 until around 00:00 the following day. Much calmer lower down - generally 15-25 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 northwestern slopes; the southeastern side should see somewhat higher bases and better breaks. A persistently wet day is possible, with around 20-40 mm indicated; local totals could vary considerably. Cold on top: air temperature broadly 2 to 6°C, feeling around -4 to 0°C in the wind - wrap up. Low confidence (Summit wind could be roughly 37-56 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 37 to 56 mph; check again nearer the time.
