Rain and strong winds are likely at times, especially in northern and western parts during Saturday and spread to most areas by the end of the weekend followed by colder, showery weather. Next week it may become drier and more settled again with some sunshine but also overnight fog patches, which could be slow to clear by day. However, Atlantic fronts could still bring further rain and strong winds across western parts of UK at times. There will probably be some marked variations in temperature across the UK but more often below average in the north and above average in the south. However, the more settled spells could bring colder conditions more widely at times, accompanied by night frosts.

There is significant uncertainty through this period. However, the second week of November may become more settled and dry for many areas with a some sunny spells. Any spells of rain are more likely in southern and southwestern areas.
