Saturday
A cold start to Saturday morning with a northerly airflow covering the country. Low pressure is to the east while a ridge of high pressure is building in from the southwest. Some snow flurries affecting eastern coasts. A further area of snow showers in northeast Scotland, perhaps falling as more persistent, but light snow for Moray and Aberdeenshire. Snow showers may also trouble western Wales and southwest England. There wil be plenty of sunshine elsewhere but it will be feeling cold. Ireland should be cold and bright with lots of sunshine, although some scattered wintry showers affecting northern and western coasts. Highs at 2 to 5C for most.

Saturday Night
Another very cold night everywhere with clear skies for most areas though cloud will build from the west overnight covering most of Ireland, Scotland and Wales and northwestern parts of England by daybreak. A band of rain of rain or sleet will follow close behind the leading edge of the cloud. This is likely to fall as snow over higher ground. Temperatures widely falling to -5 to -1C, colder in rural locations.

Sunday
A bright start to the day over much of England with an early frost and a few fog patches. Increasing cloud to the north and west as a front approaches, this bringing rain into Scotland and Ireland. The afternoon becomes increasingly damp across northern England and Wales with low cloud, drizzle, mist and murk affecting many areas. The southeast of England and East Anglia may stay bright and dry. High temperatures at a chilly 2 to 7C.

Monday
Low pressure is centred over the northwest on Monday which will lead to a cloudy start to the day for much of the country. A band of rain, some of it heavy, moves eastwards across the country and brings strong winds with it. Becoming drier and brighter through Ireland, Scotland and western parts of Wales and England later. Highs at a milder 5 to 10C.
