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.
