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.
Burns and unbridged crossings may rise quickly. Assess them at the water and turn back if unsure.
Cloud-free timing: Around 0% early, improving to around 20% later.
A rough, clagged-in day on Pole Bank (Long Mynd): summit wind broadly 10-25 mph, with gusts 20-30 mph around midday (fresh and blowy). Thunderstorms are forecast from around midday into the evening. Avoid exposed summits and ridges during the risk period. Severe spate risk based on forecast rainfall. Burns and unbridged crossings may become unsafe or impassable. Most likely from around 08:00 until around 02:00 the following day. Cloud base mostly around 500–800 m through daylight. Expect clag for much of the day, though a brief clearance is possible during the evening. Cloud is likely to hang lowest on eastern slopes; the western 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.
