A cold front will be clearing south through Ireland and the southern UK on Friday. The front has little more than broken cloud and some showers along it by then. Much brighter, colder weather follows behind the front, although there will be some bands of showers making their way from north to south. The showers could be wintry over the Grampians and northern Highlands and some heavier bursts could affect the northwest of England, Wales, the Midlands and south-central England. Feeling cold for all, but very cold along eastern coasts. Highs at just 7 or 8C for Scotland and Northern Ireland, more widely at 9 to 14C.
A chilly night across the UK. Cloud and showers will clear to the south overnight leaving a mostly dry night with clear skies. Some showers will continue along north-facing coasts and hills, particularly in Scotland and the northeast of England. Overnight lows falling widely to -3 to 0C allowing a ground frost to form. Staying just above freezing for south Wales and southern England.
High pressure to the northwest on Saturday brings a cold north to northwest flow and the risk of a morning ground frost to western areas. There is a risk of some showers, which may be wintry in nature, in the north and east of Scotland and eastern England where it will be feeling cold. Brighter and drier to the west with sunny spells and just a chance of an isolated shower. High temperatures at 7 to 11C.
High pressure brings another chilly start to the day with a risk of a ground frost. A mostly fair day with good sunny spells, although some patchy rain may affect northern Scotland with a few showers along eastern coasts of England. Highs at 8 to 13C.
