Cloud on the hills?
Intermittently covering high terrain
Banks of cloud come and go with showers, mostly above 600-700m. Clear periods on tops will occur between showers. Cloud may fill in more extensive at times if broader areas of rain pass, though detail is uncertain.

60%

Planning Outlook
A cloudy and wet week ahead as several low pressure cores draw frontal systems across the British Isles. Rain at times extensive and heavy, streams in spate with a risk of flooding, primarily western mountains. Winds start fairly light but soon increase with gales becoming widespread by Tuesday, which may persist for several days. Temperatures remain mild until later in the week when cold air begins pushing into northern Scotland - timing and extent of the arrival of cold air remains uncertain but high terrain of Scotland and possibly northern England may start to see more snow around or after next weekend.
