Updated:
UK long range weather forecast
High pressure is likely to dominate the weather across many parts of the UK during this period. This will mean plenty of dry and settled weather through to the middle of November. Where skies clear overnight some areas of fog and frost are likely to develop. Southern areas are expected to be mainly dry during this period. Any more unsettled conditions and periods of rain are more likely to affect areas further north, particularly the far north and northwest of Scotland. Winds will likely be light in the south, but there could be some spells of strong winds across the north. Temperatures will probably be close to normal overall, although some cold nights are possible at times.
Updated:
After a relatively settled start to November, around mid-month there will probably be a change toward more unsettled conditions for a time. This means an increased risk of periods of wet and windy weather for parts of the UK, perhaps more so in the south. However, there is low confidence whether unsettled, wetter weather or drier and more settled conditions will dominate by the end of the month. Temperatures will probably be close to average overall, although some colder interludes are possible.
