It's a cold morning for all parts of the country. There will be some mist and fog patches around this morning and these will be dense in places. Frosty for many too, the fog patches freezing in places. More cloud in Scotland means less mist and fog patches here. Where the fog patches lift (and they may linger in some areas of the Midlands, southern England and Wales throughout the day) there will be sunny spells. Most other areas seeing some sunny spells too, although always more cloud in Scotland. There could be lower cloud and some drizzle in western Scotland and western Ireland later this afternoon and evening. Highs at a cold 3 to 6C.
Another widespread frost developing tonight. Fog patches developing once more in Wales, the western Midlands and much of western England. Some low cloud and drizzle in the Western Isles and across western Ireland. Eastern parts of England may see some low cloud drifting in from the sea. Lows around -1 to -3C under the clearer skies, 4C in western Scotland and along eastern coasts where cloud moves in from the sea.
High pressure continues to dominate the weather across the UK and Ireland on Saturday. There will be some morning mist and fog patches in Wales, the Midlands and southern England. These lifting slowly during the day. Most places are dry with sunny spells, although some low cloud affecting western coasts and hills. Some drizzle over the western coasts of Scotland and western Ireland. Staying cold throughout the day with tops of 6C on western coasts and hills, 3 or 4C in central and eastern areas.
Changes on Sunday as a weak front passes southeast through Scotland, northern and western Ireland. The front brings outbreaks of rain with it, sleet and snow over the hills of Scotland. Western coasts and hills of Wales and England will have lower cloud and some drizzle as wel as mist and murk. More central and eastern areas also have increasing low cloud and some mist. A few bright spells in southern and eastern areas. Highs at 4 or 5C in East Anglia and southeast England, 10C in Ireland.
