[O]utbreaks of rain, sleet and snow will extend east across Scotland and northern England later Saturday evening and through Sunday morning.
This will lead to icy stretches developing in places whilst some temporary accumulations of snow are also expected.
As much as 1 to 3 cm may fall in places at low levels over eastern and northern Scotland and also the north of England on ground above 150 m.
Over the higher ground of Scotland as much as 5 to 10 cm may accumulate. Sleet and snow will turn to rain from the west and north after midnight.
This will lead to a risk of icy stretches on untreated surfaces as well as some temporary accumulations of snow.
Any sleet and snow will turn to rain from the northwest after midnight.
There is a chance of difficult driving conditions on untreated roads and slippery conditions on pavements and cycle paths are possible.
