Outlook for Saturday to Monday:

Wet and windy on Saturday with heavy persistent rain, sleet and some hill snow. Drier overall on Sunday but often cloudy with further rain on Monday. Milder.

An unsettled start, with strong winds and some showers for many parts, these most frequent in the north. Temperatures easing back towards average for most places, but still mild in the southeast. The strong winds will make it feel rather cold though. It then looks like turning colder for all parts, with a return of wintry showers for a time, especially in the north. Conditions then look like settling down as high pressure briefly builds across the country, this bringing a risk of some stubborn fog patches as winds ease. It may turn unsettled and milder again later next week. Into December, high pressure may re-assert itself, with temperatures generally close to 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.
