Periods of wet weather are likely to affect northwestern parts of the UK at times, particularly early in this period. Some heavy rain is possible and this is likely to be accompanied by spells of strong winds. South of this, across the rest of the UK, it is likely to be more settled and whilst some rain can't be ruled out at times, there is likely to be plenty of dry weather through this period. Winds will be lighter and this will bring the risk of overnight frost and fog. Overall, temperatures will be close to normal for most, but it is likely to be mild at times in the northwest. Brief colder spells are likely here in between weather systems though.

There are signs that there may be somewhat of a northwest-southeast split to the UK's weather through this period. The north or northwest is likely to bear the brunt of wet and windy spells, whilst towards the south or southeast, it may be drier and more settled. Some rain is still likely at times here though, as are brief drier spells further north. Temperatures will probably be close to average overall, but some milder spells are likely, especially in the north. Brief colder spells are likely in between weather systems though, and the south is likely to be at greatest risk of seeing some overnight frost and fog.
