Thursday
A ridge of high pressure builds on Thursday. A frosty start for many rural areas further north. The northerly flow brings some showers onto eastern coasts of England still and perhaps continuing down some westen regions of Wales into Cornwall. More cloud for the north and west of Scotland as well as most of Ireland. Light rain and drizzle could affect the far north of Scotland too. For other areas the day is going to be bright but chilly, the best of the sunshine in western and southern parts of England and Wales. Temperatures at 8 to 10C at best.

Thursday Night
Showers become more prevalent down and around northern and western coasts of Scotland overnight. Showers push in on to western regions of Ireland and perhaps again on to Wales and Cornwall too. Largely dry elsewhere. Cloud also builds and it should be a less chilly night further north but with lows close to zero in and across parts of England perhaps. Lows reaching 1 to 5C.

Friday
A frosty start for some western and northern parts of England as the ridge is maintained over much of the country. It will bring with it a largely dry day with some sunny spells but rather a lot of cloud about too. The thickest of the cloud reserved for western and northern Scotland as well as the far west of Ireland where there will be some spots of drizzle as well as some light rain. Highs at 9 to 12C.

Saturday
Low pressure to the north of Scotland on Saturday. Rain and gales, some of them severe affecting much of Scotland and Northern Ireland. Rain in Scotland and Ireland too, this reaching northwest England. Bursts of rain too for western Wales and southwest England. Drier in central and eastern areas of England. Highs at 9 to 13C.
