Probably a quieter interlude to start this period for much of the UK as high pressure builds across the north with a return of night frosts. However there is still a risk of some rain across southern parts of the country on Wednesday, although the northern extent of this is uncertain. The high is likely to migrate eastwards during the second half of next week, potentially allowing some outbreaks of rain to move into some some northwestern areas along with some stronger winds. Into December, and while signals are mixed it looks most likely that high pressure may re-assert itself close to or over the UK, with temperatures generally near average, but some overnight frost is likely, and rather cold by day where any fog persists.

The start of this period looks like being largely settled, with high pressure close to if not over the UK. However. there is also a chance of more changeable weather patterns, which would see Atlantic weather systems periodically move across the country. These will bring some wetter and windier interludes with a risk of some snow, especially for hills in the north. These conditions look more likely to dominate towards the middle of December. Temperatures generally close to average through the period.
