Melmerby Fell weather forecast.

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

Cloud-free timing: Around 100% early, falling to around 40% later.

A mixed day on Melmerby Fell: summit wind broadly 20-35 mph, with gusts 35-45 mph during the morning (gale-force winds). Much calmer lower down - generally 10-20 mph in the valley, rising towards the tops. Little or no rain expected.

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

A grey, cloudy day on Melmerby Fell: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. 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 southwestern slopes; the northeastern 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 18-29 mph, so treat the headline as mid-range.

A mixed day on Melmerby Fell: summit wind broadly 15-25 mph, with gusts 20-30 mph during the evening (fresh and blowy). A meaningful thunderstorm risk is indicated from early morning into the evening. Avoid committing to exposed ridges if storms begin to build. The ground is likely to be wet after recent rain. Cloud base around 400-700 m in the morning, lifting to 900-1200 m around midday. The top is likely to drift in and out of cloud, with the best chance of a view from around midday into the evening. Cloud is likely to hang lowest on southwestern slopes; the northeastern side should see somewhat higher bases and better breaks. Some rain is likely, with up to around 2 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 16-27 mph, so treat the headline as mid-range.

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

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

A rough, clagged-in day on Melmerby Fell: summit wind broadly 40-55 mph, with gusts 70-80 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. Much calmer lower down - generally 20-30 mph in the valley, rising towards the tops. Cloud base around 300–600 m in the morning, lifting to 600–900 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 during the evening. 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 6 to 10°C, feeling around 0 to 4°C in the wind - wrap up. Low confidence (Summit wind could be roughly 35-64 mph, which changes how difficult exposed walking may feel) - the summit peak could be anywhere from 35 to 64 mph; check again nearer the time.

Forecast confidence: Summit wind could be roughly 41-64 mph, which changes how difficult exposed walking may feel.

Cloud-free timing: Around 67% early, falling to around 0% later.
