Through Friday, southern parts of the UK remain dry with some sunshine, though some frost and fog are possible again overnight. Further north, conditions will turn windier, with gales in the far north, ahead of a band of rain arriving from the northwest. This will usher in colder air and wintry showers across northern mainland Scotland and the Northern Isles overnight.

During Saturday, the band of rain will move southwards across the rest of the UK, with the cold air extending to southern areas on Saturday night.

Cold for all from Sunday

By Sunday, even colder air from the Arctic arrives across northern Scotland, and we’ll see the start of some unsettled weather for all parts as an area of low pressure arrives from the Atlantic.

A Yellow National Severe Weather Warning for snow and ice has been issued for the north of Scotland and the Northern Isles from Sunday afternoon to Monday morning. Here, showers will turn increasingly wintry through the day with hail, sleet and some snow. Little snow is likely to settle at low levels by day, but through the evening and overnight, 1 to 3 cm may accumulate in some places within the warning area, whilst 5 to 10 cm is possible on high ground above 300 metres by Monday morning. As temperatures fall overnight, ice is likely to form on untreated surfaces.
