A changeable and often rather unsettled period looks most likely. Further areas low pressure will move in from the Atlantic and whilst all parts are likely to see some rain at times, it is southern areas which may turn out to be wettest, relative to average conditions, through this period. Strong winds are also possible from time to time. Incursions of milder air are likely towards the south, but it could remain on the cold side overall further to the north, where there is potential for sharp overnight frosts where clear skies and light winds combine. By the latter part of this period, weather patterns in the vicinity of the UK may become rather more slowly evolving.

Changeable or unsettled conditions are expected initially, with Atlantic weather systems bringing spells of rain and strong winds at times, interspersed with brighter, showery periods. Through late-November, low pressure may become slower-moving to the west of the UK, potentially bringing more prolonged rainfall, particularly to southern and western areas, along with a continued risk of strong winds. Into December, confidence becomes low, but there is a possibility that low pressure tracks shift further south as high pressure builds to the north. This could bring further rain at times to central and southern areas, while northern parts become somewhat drier. Temperatures will probably be near or slightly above average in the south, with an increasing chance of colder conditions extending southwards from the north into December.
