An area of low pressure moves across central Britain & Ireland, bringing a complex mix of rain and snow. Areas from the Midlands northwards have a high likelihood of heavy snow for many hours. A tricky mix of rain and snow for central England - snow mainly high ground. Southern regions should just see rain. Largely dry and bright for Scotland, although risk of local snow showers. Temperatures ranging from 0 or -1C north, up to 6 or 7C in southern England.
A cold day for all. Low pressure pulls away south into Europe, drawing cold air back across all of the British Isles from the north. Areas of residual snow possible, locally giving some disruptive falls. Snow showers most frequent around coasts in the west & north. Widespread ice, and previous lying snow will likely result in transport disruption. Staying close to freezing for most. Locally 5C around coasts in the south.
Staying cold with overnight temperatures well below freezing for some. A general north-westerly pattern influences the country. A bright day, with crisp winter sunshine. Wintry showers around coasts exposed to the breeze, resulting in frequent snow over the hills in Wales & northern Scotland. Central inland regions should stay mainly dry. Temperatures 0 to 3C for most, locally 5 or 6C near coasts in the south-west.
The next complex area of low pressure moves in from the Atlantic, bringing another messy day of rain and snow. A chance that milder air advances further across the country, meaning more areas will see rain and a thaw of previous snow cover. However, rain may be preceded by snow, and in northern regions it may stay as snow for many hours. Blustery winds. Highs 2 to 7C.
Most likely on the chilly side, with north-westerly winds. Areas of wintry showers, widely of snow inland and over the hills in northern regions. Some bright or sunny spells. Highs 1 to 6C, mildest near coasts in south-west.
Staying cool or cold. Further wintry showers possible. Frosty overnight. Some sunshine by day. Highs 1 to 7C.
