Forecast confidence: Thunderstorm timing is inherently uncertain and may shift by several hours.
from around midday into the evening. Leave exposed summits and ridges if thunder develops.
Cloud-free timing: Cloudy early, clearing later.
A mixed day on Cross Fell: summit wind broadly 15-30 mph, with gusts 30-40 mph during the evening (strong winds). Thunder watch from around midday into the evening: a small but credible risk is present. Watch for growing clouds and leave exposed tops if thunder develops. Much calmer lower down - generally 5-15 mph in the valley, rising towards the tops. Cloud base around 500–800 m in the morning, then around 1400–1700 m around midday and 1100–1400 m by late afternoon. Summit cloud should lift later, bringing a better chance of clear views. Little or no rain expected.
