An area of low pressure over the North Sea will bring heavy rain and snow to much of Scotland and into the north of England through Wednesday morning. Wintry showers will affect central and southern England, Wales and western and northern parts of the island of Ireland. Through Wednesday afternoon the low will track southwestward across Scotland and into the Irish Sea bringing further heavy rain to northwestern Scotland and Northern Ireland. Scattered wintry showers are possible elsewhere through the afternoon. Breezy in the northwest with gales for the Western Isles and Northern Ireland. Hail and thunder possible at times. High temperatures at 6 to 10C.
Through Wednesday night and into Thursday heavy rain, sleet and snow will continue for much of Wales and Ireland. Showers over Scotland and England will initially ease before a further band of rain, sleet and snow moves into northeast England and southeast Scotland through the small hours. Elsewhere will be mostly dry but cloudy. Overnight lows falling to -2 to 2C.
A very complex set up continues on Thursday with a large low pressure system extending along the length of the western half of the UK. This will bring further heavy rain, sleet and snow over higher ground to Scotland, Wales, Northern Ireland and the southern half of England. Rain will ease through the afternoon for most but showers will continue to affect much of England, Wales and Ireland. Gales for the far northwest. High temperatures at 7 to 10C.
An ongoing complex pattern continues on Friday with low pressure to the west of Ireland and a ridge of high pressure trying to build in the east.
