Showers or longer spells of rain as well as occasional strong winds are most likely as Atlantic low pressure systems dominate in the vicinity of the UK. Some heavy rain is likely in places, with some snow at times in the north, mainly on high ground. Temperatures varying from around average to cold at times, especially in the north. While unsettled weather is likely to continue, there may be some drier interludes between weather systems. Later in the period, there is a chance that more prolonged drier and settled conditions may begin to develop.

Low confidence in the dominant weather patterns during this period. There are signals for both unsettled conditions, bringing a risk of some heavy rain, but also periods of drier, more settled weather, which may mean colder conditions. The latter, more settled pattern is looking slightly more probable at this stage, especially early in this period.
