This Evening and Tonight:

Dry through the period with variable cloud. Cloud breaks expected in places overnight, most likely in the southwest, allowing temperatures to drop and frost to develop in many areas, with mist and fog also possible. Minimum temperature -4 °C.

Wednesday:

Cloud clearing through the morning to leave a sunny but cold day. Turning cloudier overnight, but another very cold night expected with widespread frost. Maximum temperature 5 °C.

Outlook for Thursday to Saturday:

Mostly dry on Thursday with variable cloud. Brief outbreaks of snow possible on Friday, but dry and sunny Saturday. Very cold, with fresh winds at times, particularly along the coast.

Cold northerly winds dominant across the UK in the first week of January. These will bring wintry showers (often of snow) to many coastlines (and areas just inland of these) that are exposed to onshore winds. Day-to-day changes in wind direction will change the places most exposed to the showers, but many inland locations across central and southern areas will remain mostly dry but cold - some more coherent bands of rain, sleet and snow working south at times. Into the second week of January slightly milder conditions will attempt to move in from the west, with a risk of further snow on the leading edge of these turning to rain. Colder regime more likely to the north with average to just below average in the south.

Whilst confidence in details is low, by the start of this period the transition back to westerly winds bringing Atlantic weather systems into the UK is expected to be complete, with temperatures most likely recovering to around or just below average. There is perhaps a weak signal for slowly evolving weather patterns to be more favoured than normal, such patterns increase the chances of frost and fog above normal by night.
