Conditions through this period are somewhat uncertain, and the detail especially so, but it is more likely than not that a mainly westerly regime will dominate the UK's weather. It is therefore likely that further spells of mild, wet and windy weather affect the UK at times, interspersed with colder, showery conditions with a risk of some snow in the north, mainly over higher ground. However, there is also a chance that drier, more settled conditions develop at times, especially towards the south or southeast of the UK. Temperatures are likely to be close to or a little above average overall, although with a risk of overnight frost in between frontal systems or in association with any drier spells.

Much of this period looks like being mainly unsettled, with Atlantic frontal systems moving east across the UK. These will bring spells of mild, wet and windy weather at times, interspersed with colder, brighter but probably showery conditions, with a risk of snow over higher ground in the north. However, it may become a little drier and more settled towards the south or southeast after mid-month, with the wettest and windiest weather possibly becoming more confined towards the northwest. Temperatures are likely to be a little above average overall, although overnight frost is possible at times where skies are clear and winds light enough.
