Early freezing fog patches will only slowly clear this morning to leave a sunny but cold day. Cloud thickening from the northwest later in the afternoon. Maximum temperature 5 °C.

A dry night, with variable amounts of cloud. However, clear spells, especially in the south, are likely to give freezing fog patches and frost in places. Wind increasing towards dawn. Minimum temperature -3 °C.

Thicker cloud in the north at first, with the risk of some light rain. This dying out, with sunny spells developing. Breezy and cold. Maximum temperature 6 °C.

Cloudy with risk of some light snow early Friday. Then mostly dry, cold and sunny. Breezy, exacerbating the cold feel.

Cold northerly winds dominant across the UK in the first week of January bring wintry showers (often of snow) to many coastlines (and areas just inland of these) that are exposed to onshore winds. Into the new week more coherent bands of precipitation and thicker cloud will attempt to move in from the west, with a risk of further snow on the leading edge of these turning to rain. Confidence is low in the rate of this return to a more mild Atlantic flow, with a risk of further artic airflows following fronts to resume wintry showers, especially across northern areas of the UK. Temperatures recovering to just below average for most, though further north more likely to return cold at times.

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.
