Detail is uncertain for Thursday, but a small area of low pressure is expected to pass eastwards, bringing a period of rain to most places, turning to snow on the back edge of this system across northwest England and Northern Ireland, then moving into the Midlands and Wales through the evening and overnight. Clusters of snow and hail showers will follow from the north-west. Blustery winds, risk gale force for a time. Temperatures 1 to 6C.
A chilly north or north-westerly flow on Friday. Areas of wintry showers, focused around coasts in the west and north, perhaps also eastern areas. Sunny spells in central and southern regions. Frosty overnight where sheltered. Highs 1 to 5C.
Pressure is likely to build from the west on Saturday. A few scattered showers in the west on coasts and hills. A good deal of bright sunshine. Widespread hard frost is likely early on. Highs 1 to 6C.
An area of low pressure passing southeast through the country on Sunday. This brings spells of rain, sleet and snow south with wintry showers following to the north. Highs at 4 to 8C.
A ridge of high pressure builds through the UK and Ireland on Monday. This brings a fair day for most with sunny spells. An odd shower in the east. Highs at 2 to 7C.
A milder day to the north and west with some rain moving into western Scotland and western Ireland. Dry and cold still across eastern and southern England and Wales. Highs at 3 to 8C.
