It will be a cold start to the day with icy patches in places.
For most, Sunday will be a day of sunshine and showers.
Some of the showers will be heavy and thundery with the risk of hail and sleet. Snow is likely to fall across some hills.
It will remain breezy, making it feel rather cold, with a top temperature of 11 Celsius (52F).
Showers should ease in the west later.
