Low pressure deepens north of Scotland on Sunday with a ridge of high pressure collapsing to the south. This allows a strong westerly flow to affect the country. Cloud and rain in Scotland and the north and west of Ireland. Broken cloud over most of England and Wales but thicker cloud and some drizzle on western coasts of Wales and southwest England. Highs at 7 to 12C.
A windy and unsettled day for Sunday. Low pressure is in control and will be north of the country. This brings cloud and outbreaks of rain, most to the west. Colder weather in Scotland may bring some snow over the Highlands later. Gales could occur on southern England and Wales. Highs at 7 to 12C.
Low pressure to the north of Scotland pushes fronts eastwards. This takes gale force winds, cloud and rain with it, some of it heavy at times. Rain may turn to snow over the higher ground of Scotland. Highs at 3 to 8C.
Low pressure continues to affect Scotland on Christmas Eve bringing some snow showers here, especially in the north and west. Cloud and rain clear to the south, with cooler and brighter weather following through the rest of England and Wales. Highs at 5 to 8C.
